CVS Caremark prior authorization fax number (2026)

CVS Caremark's prior authorization page prints two fax lines: 1-855-633-7673 for Medicare Part D and 1-866-255-7569 for Medicaid, each beside its phone line. The non-Medicare block prints a phone line, 1-800-294-5979, and no fax. An older copy of the Global Prior Authorization Form prints 1-888-836-0730, and the current copy says to use ePA.

Every fax and phone number below is printed on CVS Caremark's own prior authorization page or on a form it hosts. Express Scripts runs a separate set of numbers.

Which CVS Caremark number matches the request?

Phone hours are Monday through Friday, 8 AM to 6 PM Central time. The page's opening text lists only two ways to ask, ePA or a phone call, and notes that the plan decides which one a prescriber can use. The page itself prints a fax line only in the Part D and Medicaid blocks.

Is the Medicaid fax line CVS Caremark's own?

Yes. The Medicaid block sits under the page's Contact CVS Caremark Prior Authorization Department heading and names no state beside its numbers. The only state it mentions is Minnesota, in the label of the one form it links. That Medicaid PA Request Form (Minnesota) lists the payer as CVS Health, 1300 East Campbell Road, Richardson, TX 75081, with the phone (877) 433-7643 and the secure fax (866) 255-7569 that the block carries. It tells the sender not to route the form to the Minnesota Department of Health.

Is there a fax number for non-Medicare requests?

Not on the page. The Non-Medicare block lists the ePA address and the phone line, 1-800-294-5979, and links the Global Prior Authorization Form. That form, code 106-37207A 081826, prints no fax to send it to and asks prescribers to submit through ePA. The Florida, Louisiana and West Virginia state forms and the Minnesota commercial form carry the same ePA instruction.

An earlier edition of the Global form, code 106-37207A 031824, tells the prescriber to fax the completed form to 1-888-836-0730. The page does not link that edition. It does link New Hampshire, New Mexico and Texas state forms that list the same number for commercial or non-specialty drugs, each with a separate line for specialty drugs. The page and the current form leave 1-888-836-0730 out, so call 1-800-294-5979 and ask which route applies before a patient's record goes there.

Other linked forms carry fax lines of their own. The Preventive Services Contraceptive Zero Copay Exception Form says to fax signed forms to 1-888-487-9257, and the Colorado state form and the Minnesota exchange form print a different number for exchange business.

How do I route a Medicare Part D request?

For Part D the page defers to the plan. The block names no form of its own, and the form and the submission steps for a Part D determination, whether a prior authorization or an exception, sit on the patient's plan website. Read those steps before you fax 1-855-633-7673. The block's phone line is 1-855-344-0930.

A Part D plan sponsor must give notice of a standard coverage determination within 72 hours of receiving the request and of an expedited one within 24 hours (42 CFR 423.568(b) and 423.572(a)). On an exceptions request, the hours count from the prescriber's supporting statement.

What does the current Global form ask for?

It runs two pages: patient, prescriber and drug details, general clinical questions, a prescriber attestation, and question sets for eight drug classes, from topical antifungals to testosterone products. The prescriber completes the set that matches the drug and attaches the relevant clinical documentation. An expedited review box carries a certification the prescriber makes by signing. Put your practice's own number in the Secure Office Fax # field.

Can I send a CVS Caremark request electronically?

Yes. All three blocks print www.caremark.com/ePA, and the ePA page sends prescribers to CoverMyMeds or Surescripts, either through a web portal or inside an electronic health record. CVS says portal registration takes a few minutes and costs prescribers nothing.

ePA accepts prior authorizations and two kinds of exception, quantity limit and formulary. Tier exceptions fall outside it. CVS says a request moves two to three times faster this way than by phone or fax and that some automated decisions can come back in under six seconds. Chart notes and attachments travel with the request.

How do I send a CVS Caremark form from a HIPAA fax account?

For the Part D or Medicaid line, save the completed form as one PDF with the prescriber's signature and date, add the clinical documentation, enter the number from the table and check each digit against the page. The delivery certificate that follows belongs in the request file. How to fax a prior authorization request covers the steps for any payer.

The payment definition in 45 CFR 164.501 lists preauthorization of services, and 45 CFR 164.502(b) asks a covered entity to limit protected health information to the minimum necessary for the purpose of a disclosure. A fax service that stores the packet falls within the business associate definition in 45 CFR 160.103, and every Fax Pigeon plan comes with a BAA signed at signup. Basic costs $4.99 a month billed annually and covers 200 pages, sent and received combined (plans and pricing).

What if the fax does not go through?

If no delivery certificate arrives, call the phone line in the matching block before you resend. A form saved in a shared drive keeps the number it printed that day, and the Global form shows why: its fax line appears in the 031824 edition and not in the 081826 edition. A digit off sends the record to a stranger. Under 45 CFR 164.402 a disclosure the Privacy Rule does not permit is presumed a breach unless a risk assessment shows a low probability of compromise (wrong-number faxes). A practice changing fax providers can port its number before cancelling, and porting in is free on every paid plan.
