What is Twirla?
Twirla is a new contraceptive patch designed for patients who want freedom from the daily pill without committing to a longer acting method. This transdermal patch delivers 120mcg of levonorgestrel and 30mcg of ethinyl estradiol through Agile’s Skinfusion® patch, which consists of five layers and serve as the reservoir for the active and inactive ingredients, as well as a barrier to prevent accumulation of debris from daily wear. Twirla is designed to be applied once weekly for three weeks, followed by one patch free week for menstruation.
Currently there is only one hormonal contraceptive patch available for consumer use called Xulane (norelgestromin 150mcg/ethinyl estradiol 35mcg). Women who use this patch have higher blood serum concentrations of estrogen compared to oral methods (AUC0-∞ 37.7±5.6 vs. 22.7±2.8), which is associated with health concerns such as increased risk of blood clots in the legs and lungs. Agile Therapeutics, the women’s healthcare company behind Twirla, saw an unmet need in the market for a low-dose hormonal contraceptive patch. This market gap lead to the development of their newly formulated contraceptive patch, Twirla.
What are the pros and cons of Twirla?
This patch provides another option for women who desire an alternative from a daily pill, without the constraints of a longer acting method. Twirla is applied once weekly, meaning women only have to remember their birth control about three times a month rather than every day. With various daily activities and responsibilities, a weekly patch liberates women from one of those daily routines. There are other birth control options such as the Depo-Provera injection, IUDs, or implants that serve as alternatives to the pill but some women perceive these methods as more invasive compared to the patch. Additionally, given the lower dose of estrogen, Twirla appears to have a lower risk of blood clots as shown in comparator studies but remains equally effective in regulating menstrual cycles and preventing pregnancies as compared to the existing patch option.
Although the convenience of a patch is desirable, there are several noteworthy considerations with this product. As previously mentioned, Twirla’s formulation lowers the risk of blood clots, but there remains a risk of blood clots with hormonal patches compared to oral methods. Additional side effects reported with Twirla include unscheduled vaginal bleeding, weight gain, headache, and abdominal cramps. Women have also reported skin irritation when applying and removing the patch. Regarding size, Twirla is round and slightly larger (28cm2) than the Xulane (14 cm²) patch. Additionally, both Twirla and Xulane are currently only produced in one neutral shade of beige. For many women, this prevents the possibility of a discrete form of birth control which may make this a less desirable option.
Are there different considerations with a patch compared to other contraceptive methods?
Given the hormones in Twirla, the patch works just like the pill in terms of preventing pregnancy by delaying ovulation. It can be applied on the upper arm, buttocks, back, or lower abdomen. The patch is designed to withstand activities such as exercising, swimming, showering, etc. If the patch does happen to fall off during the week, it can be reapplied or a new patch may be used in its place. If the patch has been off more than 24 hours, a back up method such as condoms should be used for the next seven days of the new patch cycle. Although it’s rare (<2% of the time), healthcare providers recommend daily checks to ensure the patch has not accidentally fallen off. Patches should not be worn longer than the week they are intended and consequences of doing so include bleeding, spotting, and increased risk for unintended pregnancy. If a patient is more than 48 hours late transitioning from the existing patch to a new patch, then a back up should be used for seven days. Like all other birth control methods, Twirla does not protect against sexually transmitted diseases or HIV.
Is Twirla a good option for everyone?
There is no one-size fits all method that is right for all women. Some women might be at greater risk for adverse effects with the patch. Agile reported reduced efficacy in preventing pregnancy for women who weigh 202 pounds (92kg) or more, or who have a BMI of 30 kg/m2 or greater. As a result, the drug company initially issued a Limitation of Usestatement in their product labeling that documented this clinical outcome. Since gaining FDA approval, this limitation has transitioned to a listed contraindication. Xulane’s package insert lists the same contraindication, yet is regularly prescribed in women with a BMI >30 kg/m2. Studies have shown that the decrease in efficacy does not preclude the use of these patches in obese women. To combat the associated risks, additional counseling to emphasize the importance of strict compliance with the patch for optimal protection is necessary. Studies have also shown an increased risk in blood clots in women who are overweight and those who smoke. Additional contraindications for using Twirla include women with a high risk of thrombotic disease, who experience migraine with aura, who have liver disease, or who have undiagnosed abnormal uterine bleeding.
Is Twirla available now?
Twirla was approved by the FDA earlier this month on February 14, 2020. As part of the approval process, the FDA is requiring Agile to conduct a long term, observational post-marketing study to further evaluate the risks of blood clots in new users of Twirla. With its recent approval, the manufacturer is now focusing their attention on commercializing Twirla for consumer use. They hope to complete the manufacturing process and expect to ship the initial product to wholesalers as early as the end of this year.
With patient needs and safety in mind, the approval of this medication further expands the range of contraceptive options available for women. Given that there have only been three non-daily combined hormonal contraceptive methods made available since 2001, this is a valuable and timely option for women who seek alternative methods.

What is endometriosis?
Endometriosis is characterized as a condition in which endometrial tissue, which normally lines the uterus, develops outside of the uterine cavity in abnormal locations such as the ovaries, fallopian tubes and abdominal cavity.1 Endometriosis is a common cause of chronic pelvic pain in women and can sometimes be associated with infertility.2 It is estimated that 1 in 10 women suffer from endometriosis (with percentages even higher in women with chronic pelvic pain and infertility). On average, it takes anywhere from 3 to 11 years from the onset of pain symptoms for women to be accurately diagnosed with endometriosis.3
As pharmacists, it is important to establish our role in patient care and to be aware of this underdiagnosed condition and the role of hormonal contraception in managing symptoms and the disease. We can assist patients with endometriosis by having confidence in the medication they were prescribed and keeping in mind the individual treatment goals in each patient. While there is no definitive cure for endometriosis, there are pharmacological approaches in the management of the associated pain. While there are many different options available for women with endometriosis, this article will be focusing on the use of hormonal contraceptives in endometriosis pain management. Additionally, it is important to keep in mind that no hormones are free of side effects and severity and tolerability can vary significantly; not all types of endometrial pain respond equally to hormonal treatment.4
What is the role of hormonal contraceptives in endometriosis treatment?
Combined hormonal contraceptives (CHCs) and progesterone only pills (POPs) have been used for pain management associated with endometriosis. Hormonal contraceptives help to slow the growth of new endometrial tissue and may prevent formation of new adhesions which can help decrease the pain patients have. However, hormonal contraceptives will not eradicate any endometrial tissue that currently exists in the patient.5
There are a few differences in tolerability and the level of evidence for each treatment. For assessing the different types of contraceptive treatment for endometriosis, the European Society of Human Reproduction and Embryology (ESHRE) has created a grading scale as part of their justification for treatment:
Grade A: treatment has been backed by meta-analysis, systemic review or multiple RCTs (high quality).
Grade B: treatment has been backed by a meta-analysis, systemic review or multiple RCTs (moderate quality), single RCT, large non-randomized trial, case-control or cohort studies (high quality).
Grade C: treatment has been backed by a single RCT, large non-randomized trial, case-control or cohort studies (moderate quality).4
CHCs may considered as it can reduce endometriosis-associated dyspareunia, dysmenorrhea and non-menstrual pain.4 Oral CHCs are considered “Grade B”.4 It is important to note that endometriosis is considered to be a predominantly estrogen-dependent disease. It is possible that the estrogen component of CHCs may mask the effect of the progestin by possibly activating the disease. However, it has been argued that ethinylestradiol doses are too low to reach an activating threshold.4 According to the American College of Obstetricians and Gynecologists (ACOG) guidelines, CHCs showed significant decrease in pain in patients and if that therapy is not tolerated patient could move on to progestins. Unlike the ESHRE, they did not differentiate between types of contraceptives and their related effectiveness.5
Among the CHCs, it is important to recognize that different dosage forms have different grades of evidence of efficacy in the ESHRE guidelines. Continuous CHCs (active tablets only) were given a “Grade C”. Vaginal contraceptive rings and transdermal patches were also given a “C”.4
Progestin-only pills are considered “Grade A” by the ESHRE guidelines because they have the most evidence to date in reducing endometriosis-related pain. Additionally, while Levonorgestrel-containing IUDs are not FDA approved as treatment for endometriosis, they are given a “Grade B” as an option to reduce pain related to the disease.4 Additionally, the ACOG guidelines recognize the use of levonogersterol-containing IUDs to reduce endometriosis related pelvic pain, but emphasized that potential side effects like irregular bleeding and weight gain are common.5
Another type of progestin contraceptive that can be used for endometriosis-associated pain is Depot medroxyprogesterone (DMPA). DMPA works to prevent follicular growth preventing ovulation.6 ACOG recognizes DMPA as a suitable treatment as it has been approved by the FDA for treatment of endometriosis-associated pain.5 Furthermore, ESHRE gave DMPA a “Grade A” as an option to reduce endometriosis-related pain.4
As pharmacists, we serve a vital role in the patient care plan and can be there to help patients recognize the types of treatment options available to them. As a patient, it may be hard navigating through the different contraceptive options that they have for endometriosis pain management. Pharmacists can help patients navigate these options in order to help improve their quality of life.

Why is preconception care important?
Roughly 4 million pregnancies occur in the United States annually.1 A common misconception is that preconception care is only a health care need when there is an intention to become pregnant. However, because nearly half of all pregnancies in the United States are unplanned, most birth defects occur within the first 3 months of pregnancy, and nearly one-fifth of pregnant women in in the United States receive no prenatal care before the end of their first trimester, preconception care is a serious population health issue deserving of attention.2-4
Why should pharmacists consider being involved?
Although preconception care is recommended to be routinely provided to all women of reproductive potential, gaps exist. With an estimated 90% of Americans living within 5 miles of a community pharmacy, community pharmacists have been proposed as an ideal provider of selected preconception care services to help fill these gaps and support preconception care initiatives.5,6
Where do we even start?
My PGY-1 community pharmacy residency was an incredible year filled with many great experiences that truly helped sculpt my professional practice during my first year as a pharmacist. One of the requirements was to develop and implement a research project; the topic chosen was preconception care. In full disclosure, I did not know much about it when I started the project and quickly found I had more questions than answers. However, I rapidly realized how deserving it is of continued attention.
Our primary objective was to perform a needs assessment using modified evidence-based core indicators:
The above parameters were assessed with the use of a 1-page patient survey, retrospective chart review, and vaccine database review.3,7
Of the 110 patients who were asked to complete the survey, 99 patients took the survey and were included in the study for analysis. More than 75% of the patient population reported being sexually active and only about 50% of participants indicated they used some form of contraception, highlighting a large proportion of the population with the potential to become pregnant, as well as for unplanned pregnancy.
96% of study participants were found to have at least one health concern that could adversely affect a pregnancy if she were to become pregnant. The majority of study participants reported at least one of the following:
- Abnormal BMI
- Missing documentation of at least one assessed vaccination
- No form of daily multivitamin that contained folic acid
Additionally, roughly half of survey participants were on at least one medication with potentially teratogenic effects.
Not only was preconception care need established across the majority of survey participants, but needs were found to span multiple preconception care parameters as well as differing demographics. However, despite the demonstrated need, 78.8% of the survey participants indicated they were not interested in receiving more information on preconception care. Therefore, pharmacists must play an active role in identifying and educating eligible patients.
Are you ready to begin implementing preconception care services within the community pharmacy setting?
If the answer is yes — and I hope it is — what are the next steps?
In identifying these concerns, we hoped that the results could be used in developing new clinical services to support preconception care needs.
Pharmacists already provide non-dispensing services via multiple service models, therefore preconception care services may be built within existing frameworks.6,8,9,10 This support can include:
- Screening for preconception parameters
- Optimizing pharmaceutical care plans for adequate disease state management
- Counseling for prescription and over-the-counter (OTC) products to assist in family planning
- Prescription contraception via statewide protocol or collaborative practice agreement (depending on state/scope of practice)
As we continue to learn more about the need for and how preconception care fits into community pharmacy practice, I leave you with one final question:
Where might preconception care services fit within your pharmacy workflow and how might you implement these types of services to better the health of the patients you serve?

The use of prescription medications by pregnant women has increased over the past 30 years and with the usage comes an increased associated risk of exposing the fetus to the drugs. These medications can cause fetal abnormalities during a pregnancy. Often, for unique reasons, women are not concomitantly prescribed contraception or are not educated regarding the importance of using contraception while taking these high risk medications. Although, the use of teratogenic medications may be necessary for a woman’s health it is important to use birth control while on these drugs to prevent exposure during a pregnancy.
What are teratogenic medications?
Teratogens are agents that interfere with fetal development when exposed during pregnancy and cause abnormalities. Examples of these teratogens include, but are not limited to alcohol, smoking, and various prescription medications.
The thalidomide tragedy is an unfortunate example of what teratogenic drugs can do to the development of fetuses. In the late 1950s and early 1960s, thalidomide was widely used for the treatment of nausea in pregnant women soon after, it became apparent that the treatment caused malformations of the arms and legs. Currently, the drug is limited to use for the treatment for various conditions such as skin lesions caused by leprosy and multiple myeloma.
Why is it important to take contraception while on these medications?
Many women take potentially teratogenic medications for health conditions such as hypertension, diabetes, cholesterol, etc. and taking these medications while pregnant increases the risk of fetal malformations and spontaneous abortions. The use of contraception while taking these medications reduces the risk of having pregnancies with abnormalities.
A study was conducted to evaluate teratogenic medications and associated prescription of contraception in the primary care setting. They found that 25% of the patients that participated in the study were prescribed at least 1 high risk medication from Table 1 and of those patients over half did not have contraceptive management. Ondansetron, often used for nausea in pregnancy, was excluded from the second analysis resulting in 10% of the patients on a high-risk medication and 61.9% of those patients were found to be without any use of contraception management.
The table below summarizes the medications that were used in a study and the teratogenic risks associated with them.
Table 1. Common teratogenic medications and related potential fetal effects
|Medication Name||Potential Fetal Effects|
|Atorvastatin, Simvastatin, Pravastatin||Congenital abnormalities in infants and skeletal malformations in rats and mice|
|Topiramate||Cleft lip/palate and hypospadias|
|Valproic Acid||Facial dysmorphology, congenital heart defects, spina bifida, cleft lip/palate, development delays|
|Paroxetine||Cardiac malformations and pulmonary hypertension|
|Lisinopril||Spontaneous abortion, oligohydramnios, newborn renal dysfunction|
Who is at risk?
Women who were less than 25 years of age had a low probability of receiving contraception when prescribed a teratogenic medication compared to patients who were of advanced maternal age (over 35 years old). Demographically, among all women who participated in the study, 60% belonged to a minority group compared to the 40% who were not in a minority group which suggests that minorities may be prescribed teratogenic medications more frequently compared to their non-minority counterparts.
Why is this a problem?
The study did not explore why this trend was seen. There are multiple challenges that family physicians face regarding contraception and teratogenic medication management. The first is that physicians may not be able to identify their patients’ family planning intentions, making appropriate counseling challenging. Second, they may experience difficulty finding clinically relevant information on the teratogenic medications. Additionally, while some medications are monitored strictly such as isotretinoin (Accutane), most are not, which makes it difficult for the provider to regularly re-evaluate reproductive plans when patients do not make frequent office visits. Lastly, specialists might prescribe these medications and fail to communicate with the primary care physician leaving the management of contraception up to the patient.
What can pharmacists do?
It is important to practice interprofessional collaboration which results in safer prescribing practices. Pharmacists are now able to prescribe birth control in some states and can educate patients about contraception use while on teratogenic medications and directly provide contraception if needed and document it.

What’s this new pill?
Slynd® is the new progestin-only oral contraceptive approved by the FDA in May 2019. This novel progestin-only pill (POP) contains drospirenone 4 mg in each active tablet, which is a higher dose than what is found in drospirenone-containing combined oral contraceptives (COCs).
Table 1. Products with drospirenone.
Yasmin, Zarah, Syeda, Ocella
Drospirenone 3 mg, ethinyl estradiol 30 mcg
Drospirenone 3 mg, ethinyl estradiol 30 mcg, levomefolate calcium 451 mcg
Yaz, Gianvi, Loryna
Drospirenone 3 mg, ethinyl estradiol 20 mcg
Drospirenone 3 mg, ethinyl estradiol 20 mcg, levomefolate calcium 451 mcg
Drospirenone 4 mg
This will be the second POP formulation available, in addition to the many norethindrone 0.35 mg products currently available.
What are the features of this new pill?
This pill provides pregnancy prevention with a 24/4 dose regimen. In the ongoing evolution of contraception, the goal has always been to improve efficacy as well as minimizing adverse events. Estrogen dose reduction and shortening of hormone-free intervals have been helpful to meet these goals. As a result, Slynd was developed with a 24/4 dose regimen which provides a more stable hormonal timeframe compared to traditional 21/7 dose regimens, achieving greater pituitary and ovarian suppression. For this reason, the 24/4 regimen has less hormone withdrawal effect and improves pelvic pain, headaches, breast tenderness, and bloating symptoms that are reported during the hormone-free days with 21/7 regimens.
Figure 1. Slynd pill pack containing 24 active pills and 4 inactive pills.

Slynd also allows a 24-hour missed pill window which improves reliability and bleeding profiles in the event of a missed dose. One study compared two arms — one with four missed doses (four 24-hour delays) and the other with no missed dose during the cycle. Even with four missed doses in the cycle, there was adequate ovarian suppression and the same follicular size was observed in both arms.
Drospirenone inhibits ovulation by suppressing luteinizing hormone (LH) secretion. Additionally, by modifying cervical mucus, it reduces sperm transport and thus prevents fertilization. Unlike other conventional synthetic progestins, drospirenone has a similar profile to endogenous progesterone. As an analogue of 17-alpha spironolactone, drospirenone has anti-mineralocorticoid and anti-androgenic activity. Due to the anti-mineralocorticoid activity, it increases urinary sodium and serum aldosterone. Therefore, compared to other COCs causing fluid retention and edema, drospirenone has an ability to reduce blood pressure.
Should we be worried about blood clots with drospirenone?
Drospirenone was first introduced to the market in combination with low dose ethinyl estradiol as a contraceptive well suited for women with premenstrual dysphoric disorder (PMDD), moderate acne, polycystic ovarian syndrome and hirsutism.
While the FDA is concerned about the potential correlation between contraceptives containing drospirenone and blood clots, the overall result of two prospective multicenter phase III studies reported no single case of venous thromboembolism (VTE) in patients who used POP. FDA has funded a study to investigate the correlation, and still is reviewing other clinical trials. In 2011, the FDA reported that “preliminary results of the FDA-funded study suggest an approximately 1.5-fold increase in the risk of blood clots for women who use drospirenone-containing birth control pills compared to users of other hormonal contraceptives.”
Other studies have shown use of drospirenone-containing COCs was not associated with increased risk of thromboembolic events compared to other COCs containing other progestins. Due to data limitations, the causality is still unclear, and FDA will provide updates once available.
While there is an increase in the relative risk of this rare adverse event with COCs containing drospirenone, the incidence is still very low and much lower than pregnancy and postpartum periods. ACOG’s Committee on Gynecologic Practice has concluded that the risk of thromboembolism in patients who use drospirenone-containing COCs is very low.
It is unknown whether Slynd increases the risk of VTEs, however, any potential risk with this POP is expected to be lower than COCs containing drospirenone.
Which patients should not use this pill?
Drospirenone is contraindicated in women with positive or unknown antiphospholipid antibodies, ischemic heart disease, stroke, current or history of breast cancer, hepatocellular adenoma, malignant hepatoma, and severe hepatitis. Clinicians should use this medication with caution in patients who are taking other medications that can predispose them to hyperkalemia, or monitor potassium level.
The drug interaction profile is similar to drospirenone-containing COCs. Although drospirenone is metabolized independently of P450 enzymes, it is a minor substrate of CYP3A4. It is recommended to avoid use in patients taking strong 3A4 inhibitors to prevent hyperkalemia. Strong P450 and P-glycoprotein transporter inhibitors and inducers can affect the serum concentration, efficacy, and adverse effects.
What’s the bottom line for place in therapy?
In conclusion, Slynd can be used in most patients and will be an important option for patients with contraindications to estrogen — including history of high blood pressure or smoking above age 35 — PMDD, as well as patients desiring contraception without androgenic effects, such as those with acne or polycystic ovary syndrome (PCOS).

One area of focus for ASP chapters is to “provide education on the pharmacist role in reproductive health, including hormonal contraceptive options and access to hormonal contraceptives.”
This year at the University of Michigan – College of Pharmacy, our APhA-ASP chapter is working to promote women’s health at our college and within the university. Since women’s health pharmacy is a niche area within the profession, we wanted to provide a career development event for pharmacy students to be exposed to “The Pharmacist Role in Rxeproductive Health”.
On Monday, November 11th, our chapter hosted its first “Rxeproductive Health” event focusing on pharmacist involvement in a variety of fields within reproductive health. We invited Dr. Lauren Leader, PharmD, BCPS of Michigan Medicine and Dr. Brooke Griffin, PharmD, BCACP of Midwestern University and Birth Control Pharmacist to educate our students on topics of peripartum health, pharmacist prescribing of hormonal contraception, and policy to expand the pharmacist profession in women’s health. The event began with phast phacts (“fast facts”) on women’s health and where in the United States pharmacists have prescribing authority for hormonal contraceptives, followed by a question and answer between our panelists and audience. The program ended with a collaborative reflection with our guest speakers on a policy brainstorming session, asking ourselves: “What role or roles do we want to see pharmacists to have in women’s health and reproductive health?” Despite an all-day snow storm in Michigan that day, we had a lot of students attend and participate, making for a memorable and meaningful event.
As I reflect on my first three years of pharmacy school and as my interests in women’s health continues to grow, I have started to notice the lack of women’s health events outside of the lecture room. APhA-ASP launching their campaign last year has given our organization the opportunity to advocate for women’s health to the community and to our college of pharmacy. “The Pharmacist Role in Rxeproductive Health” was our first focused women’s health event for ASP, providing our students with the knowledge and networking to advocate for this population in health care. Given the success of our first event, I am excited to see where our ASP chapter will go from here.

About the Author:
Tina Bednarz, PharmD Candidate is a third-year pharmacy student at the University of Michigan – College of Pharmacy where she is the Policy Vice President of the chapter’s APhA-ASP organization.
The American Society for Emergency Contraception (ASEC) recently held their annual EC Jamboree in Washington, DC. Participants included health care providers, researchers, reproductive health advocates, and pharmaceutical stakeholders.
One highlight was the key clinical discussions centered on drug interactions between emergency and other hormonal contraceptives, including ulipristal acetate (ella, Afaxys Pharma).
A selective progesterone receptor modulator, ulipristal acetate binds the progesterone receptor, and has both antagonistic and partial agonistic effects. When ulipristal acetate is in the picture, along with another progestin hormone, there will be competition for the progesterone receptors. For this reason, the patient’s use of another progestin-containing hormonal contraceptive either before or after may impact its effectiveness 
This theory is based on the pharmacology of the drugs and was supported by a European study. The study looked at the impact of starting a desogestrel progestin-only pill the day after taking ulipristal acetate, compared to starting the same progestin-only pill without ulipristal acetate beforehand. The group that had taken ulipristal acetate showed a slower onset of action of the progestin-only pill in preventing ovulation and thickening the cervical mucus. This particular progestin-only pill is not available in the United States 
Following this study, Afaxys revised the ulipristal acetate label in March 2015 to include: “Hormonal contraceptives: Progestin-containing contraceptives may impair the ability of ella to delay ovulation … Avoid co-administration of ella and hormonal contraceptives. If a woman wishes to start or resume hormonal contraception after the intake of ella, she should do so no sooner than 5 days afterwards, and she should use a reliable barrier method until the next menstrual period.“ 
Last year, another study found that combined oral contraceptives containing estrogen and progestin hormones are expected to reduce efficacy of ulipristal acetate, as well. In this United States study, researchers evaluated the impact of initiating an ethinyl estradiol/levonorgestrel combined pill 2 days after ulipristal acetate use . More participants experienced ovulation when the combined pill was initiated compared to those who did not initiate any hormones after ulipristal acetate.

The inaugural States Forum on Pharmacist Birth Control Services was recently held in conjunction with the American Pharmacists Association (APhA) 2019 Annual Meeting in Seattle, Washington. This session was hosted by Birth Control Pharmacist. Most states were represented at the forum with over 60 participants, and there was meaningful discussion on how to make this service not only possible, but also impactful.
Sally Rafie, PharmD kicked off the program with a review of the current landscape. Sharon Landau MPH followed by facilitating brief updates from the states, including those that have implemented pharmacist birth control services, are in progress, and are considering this action. State representatives shared successes, challenges, and lessons learned. Don Downing, BSPharm then led a focused discussion on payment for pharmacist services.
Here are 5 pearls to take away from the States Forum:
1. Even states that tend to be conservative, particularly with women’s health, should consider pursuing policy.
Legislation to allow pharmacist birth control services is a nonpartisan effort. While some of the early states had Democratic lawmakers sponsoring bills, more than half of those passed and under consideration are sponsored by Republican lawmakers.
2. Avoid certification because this is standard practice for pharmacists.
Payment for pharmacist services is critical to success. Multiple states cited this as the biggest challenge they are currently facing. Health plans may look for “certification” to credential a pharmacist as a provider or pharmacists assessing a body system to determine the service is eligible for payment. Washington has had success with payment for pharmacist services by recognizing pharmacists as medical providers and using legislation to mandate payment for pharmacist services by all government and private health plans.
3. Provide education for pharmacists and identify pharmacist and physician champions in advance of proposed legislation.
Pharmacists are not the only stakeholders who champion initiatives for pharmacist birth control services in the states; legislation has even moved forward without necessarily engaging the state pharmacist associations or other pharmacists. In some states, pharmacists have more concerns than other stakeholders and may even testify in opposition of proposed legislation. Many of these concerns may be due to knowledge gaps and can be addressed with education opportunities in advance of legislation. Identifying physician champions is important, particularly for testifying in support of any proposed legislation. Check with local teaching hospitals for family planning fellows who will likely be enthusiastic about engaging in this work.
4. We need to promote our birth control services as a profession, as well as individual pharmacists and pharmacies that offer the service.
While pharmacists are getting trained and geared up to provide this service, the public remains largely unaware. Some pharmacies are seeing low patient demand for their birth control services. With over 1100 participating pharmacies on the birthcontrolpharmacies.com map, there is an opportunity to have a greater impact in serving communities.
5. Join us next year for the States Forum.
Pharmacists valued sharing ideas, experiences, best practices, and strategies. Especially those in states who are considering legislation found the forum to be helpful. States that were farther along in implementing pharmacist birth control services were more than willing to share and help other states.

As of April 2019, California’s State Medicaid program, Medi-Cal, is providing payment for selected pharmacist services. This change is due to legislation (California Assembly Bill 1114) that was passed in 2016.
What is covered?
Pharmacist services are benefits for eligible fee-for-service Medi-Cal beneficiaries.
The following pharmacist services are now covered:
- Hormonal contraception
- Tobacco cessation
- Travel health
At this time, Medi-Cal is allowing pharmacists to bill for the following CPT codes:
- 99201 – New Patient (~10 minutes)
- 99212 – Established Patient (~10 minutes)
- 90471 – Immunization administration only
A new patient is one who has not received any pharmacist services at the same pharmacy in the last 3 years. An established patient has received pharmacist services at the same pharmacy within the last 3 years.
The rate of reimbursement for pharmacist services is 85% the physician rate. This is a change for reimbursement of the pharmacist service only. There is no change to the reimbursement for any medications that are furnished (prescribed and dispensed) — those have always been reimbursed at the same rate regardless of what provider type wrote the prescription.
Pharmacist services must be billed by a Medi-Cal enrolled pharmacy. Since payment will be made to the pharmacy (and not any individual pharmacists), bills must be submitted by the pharmacy and include the rendering provider/pharmacist information.
How do pharmacists get started with billing?
Pharmacists must enroll as an Ordering, Referring, and Prescribing Provider (ORP Provider) with the California Department of Health Care Services (DHCS) in order to bill for these services.
Before beginning the enrollment process, pharmacists will need:
- A Type 1-Individual National Provider Identification (NPI) number. It is free to sign up for your NPI number online and only takes a few minutes.
- A digital copy of their pharmacist (RPH) pocket license from the California Board of Pharmacy.
- A digital copy of their California Drivers License.
To complete the ORP Provider enrollment process, follow these steps:
- Go to the PAVE Portal. If you are a pharmacy owner, you likely already have an account that you use to manage your pharmacy’s Business Profile account. You can invite your staff pharmacists as users for the pharmacy’s Business Profile, so that they may associate themselves with the pharmacy.
- Select New Application.
- Select “I’m new to Medi-Cal and I want to create a new application” and “I’m an individual licensed/certified healthcare practitioner. See screenshot below.
- For Business Structure, select “I’m an Ordering/Referring/Prescribing (ORP) provider.” See screenshot below.
- For NPI number, enter your Type 1-Individual NPI number. This is your personal pharmacist NPI number, not the pharmacy’s NPI number. See screenshot below.
- For Provider type, select Other and type “Pharmacist” in the box. See screenshot below.
- For the remaining steps, follow the instructions to complete your application. TIP: When entering your professional license information, there should be no space between the alpha character and the license number. For example, enter your pharmacist license as RPH12345 without any spaces.
For technical support, call the PAVE Help Desk at (866)252-1949, Monday – Friday, 8:00 am – 6:00 pm Pacific time, excluding state holidays.
When can I start billing?
Visit dates on April 1, 2019 or after can be billed to Medi-Cal. Pharmacists will need to wait for their enrollment as an ORP provider to be approved before they can begin billing — you should expect this to take 3 months and may take up to 6 months.
How do I bill?
All claims must be submitted using CMS Form 1500.
