Over-the-Counter (OTC) Contraceptive Coverage
What are OTC contraceptives?
Contraceptives, or birth control, help to prevent pregnancy. And some, like condoms or dental dams, also help you protect yourself from sexually transmitted infections. Over the counter (OTC) just means you can buy it without a prescription.
Which OTC contraceptives are covered?
All FDA-approved over-the-counter contraceptives, provided by an in-network pharmacy, in-network online service, or in-network provider are covered with no cost shares by CHPW Individual & Family Plans including:
- Oral contraceptives, like birth control pills
- Emergency contraceptives, like the morning after pill
- Birth control barrier methods, like condoms and dental dams
- Sponges and more
This benefit is available to everyone, for any medical purpose, inclusive of all sexual orientations. There is also no age limit.
How to purchase contraceptives
Make your purchase at an in-network pharmacy, in-network online provider, or in-network clinic and your CHPW Individual & Family plan will pay you back (reimburse you). But you do need to let us know you made the purchase and provide receipts, by submitting a claim.
Keep in mind, some oral contraceptives like the birth control pill or the morning after pill, are not available on the shelf at most pharmacies. To buy in store, you may need to talk to someone at the pharmacy counter.
Also, if you purchase OTC contraceptives from a store that is not in your plan’s network, like a convenience store or vending machine, you will not be able to get reimbursed.
How to get reimbursed for OTC contraceptives
To get reimbursed for over-the-counter contraceptives, follow these steps:
- Make your purchase from an in-network pharmacy or provider.
- Save your receipts.
- Submit your claim within 90 days, by mailing your reimbursement request.
- Send your request in writing by mail including your receipts from the in-network pharmacy or provider directly to:

Emergency Fill is when a participating pharmacy dispenses to a Member a prescription drug that is subject to Prior Authorization under their plan, without first obtaining that authorization. The participating pharmacy provider uses their professional judgment to identify that the Member has an “urgent medical need” requiring immediate fill of the prescription medication.
CHPW covers Emergency Fills for the drugs on our formulary with the following limitations:
- Emergency Fills are not available for certain Specialty Drugs, such as oncology drugs, hepatitis C, biologics, multiple sclerosis treatments, and enzyme replacements, which do not meet the criteria for “urgent therapeutic need”
- Emergency Fills are not covered at Non-Participating Pharmacies
Only the Emergency Fill dosage of the Prescription Drug is covered. In the event that the Prescription Drug is continued for treatment beyond the approved Emergency Fill, standard formulary restrictions and utilization management procedures will apply.
You will be responsible for your Cost Share of the Emergency Fill supply, including applicable Deductibles, Coinsurance, and Copayments. Please refer to the Schedule of Benefits for details. The cost share is based on the tier in which the Prescription Drug is included in the 2023 Formulary and 2024 Formulary.
