Special medications, 90-day supplies, travel, and contraceptives
Get a Larger Supply of Select Medications
CHPW covers 90-day supplies for most chronic medications. Ask your physician or pharmacist for a 90-day supply of your medications at your next visit.
Some complex or chronic illnesses require specialty drugs that regular CHPW pharmacies don’t offer. Specialty drugs are covered when dispensed through Accredo Specialty Pharmacy or participating Community Health Center pharmacies. Check our formulary for your specialty drug and ask your local Community Health Center if their pharmacy supplies your medication.
If you’re traveling outside of our coverage area, please contact us. Usually, prescriptions filled outside of our network aren’t covered. Pharmacies can dispense up to a 72-hour supply of a medication in an emergency.
Emergency pills are a safe and effective way to prevent pregnancy. The sooner they are used after unprotected sex, the better they will work. They can be used up to 120 hours (5 days) after unprotected sex. Emergency contraceptive pills are available at most pharmacies in the state of Washington without a prescription and are available at clinics, doctors offices, or online.
OTC contraception coverage
Over the counter (OTC) birth control, also known as contraceptives, are covered by Apple Health (Medicaid) and CHPW without a prescription at no cost to you. Some birth control, like condoms, can also help prevent sexually transmitted infections.
What is OTC birth control?
OTC birth control such as condoms and most emergency contraceptives (e.g., morning after pill) can be obtained without a prescription or a visit to your doctor. For a list of covered OTC birth control products, see the Apple Health covered OTC contraceptive list.
How to get OTC birth control
Apple Health and CHPW cover OTC birth control at no cost when billed by a pharmacy.
- Follow the instructions in the Find a pharmacy section to locate a pharmacy that accepts Apple Health coverage.
- Go to your pharmacy and speak with the pharmacist about which OTC birth control is best for you. Bring your Apple Health/CHPW card with you.
- You do not need a prescription, but you must go to the pharmacy counter so they can bill Apple Health.
- If your pharmacy has questions on how to bill for OTC birth control, refer them to the CHPW Pharmacy page for more information.
- Only products included in the CHPW pharmacy database are covered. For a list of covered OTC birth control products, see the Apple Health covered OTC contraceptive list.
Limits on OTC birth control
There are no limits on age, quantity, or frequency.
Can I buy OTC birth control and be reimbursed for the cost?
No, OTC birth control must be billed by a pharmacy. You cannot be reimbursed for OTC birth control you purchase yourself.
When a prescription is needed for birth control
Some methods of birth control require a visit to a doctor.
- Birth control pills
- Patches or rings that are taken daily or weekly
- As well as depot-medroxyprogesterone (DMPA, Depo-Provera)
- Intrauterine devices (IUD)
For more information on choosing the birth control that is right for you, you can visit the Department of Health birth control and emergency contraception page. You can also contact your primary care provider (PCP) or other health care provider for guidance.

Personal Medication Coach Program
The Personal Medication Coach Program helps members who are managing more than one medical issue and are taking multiple medications. We partner with MedWiseRx to make sure your medications are working effectively and safely.
Some drugs require prior authorization. This means CHPW has to approve coverage before we can help you pay for them. Check whether your medicine needs prior authorization or has any coverage restrictions by calling Customer Service or checking our list of covered medications (formulary).
- If you need medicine that isn’t listed on our formulary, you can request a coverage determination review through Customer Service.
- If your coverage is denied by Express Scripts, you may appeal the decision with CHPW. Read about how to appeal or file a grievance.
- If you paid full price for a prescription at a retail pharmacy, you can ask for a reimbursement. Check the formulary to make sure there were no restrictions on your medication before you ask to be reimbursed. Fill out a reimbursement form and either fax or mail it to Express Scripts.
- You can submit a request for excluded drugs by sending in an Exception to the Rule Request Form.
