CVS Caremark Fax Number — Prior Authorizations and Coverage Reviews

CVS Caremark is the pharmacy benefit manager arm of CVS Health, and it deals mostly in coverage decisions rather than dispensing at a counter, so its faxes are about authorizations, not prescriptions to a store. A prior authorization, formulary exception, or appeal goes to Caremark's clinical review team on a fax that is specific to the medication and the member's plan, printed on the form itself. Prescribers pull those forms from the Caremark provider portal or submit electronically through tools like CoverMyMeds and Surescripts. Because Caremark administers many different employer and health-plan benefits, always take the fax from the current form for that member rather than reusing a saved number.

What You Can Fax to CVS Caremark

  • Prior authorization request forms
  • Formulary exception requests
  • Coverage determination appeals
  • Clinical notes supporting medical necessity
  • Step-therapy override documentation
Tip: Remember that Caremark handles benefit coverage, not filling at a retail counter, so its fax intake is for authorization paperwork tied to a drug and plan. This documentation is protected health information; a HIPAA-eligible service such as Send FAX Mail's Business plan ($79.99/month) keeps it compliant and returns a delivery receipt to file with the case. Include the member ID, group, and date of birth so the review attaches to the right benefit.

Faxing to CVS Caremark — FAQ

No — CVS Pharmacy is the retail counter that dispenses prescriptions, while CVS Caremark is the benefit manager that decides coverage. A store fax reaches a pharmacy queue; a Caremark fax reaches a clinical review team, and the two are entirely separate.

It's printed on the drug-specific PA form that prescribers obtain through the Caremark provider portal for that member's plan. Since numbers differ by medication and benefit, use a current form rather than a copy saved from an earlier case.

Yes, Caremark accepts prior authorizations electronically through platforms such as CoverMyMeds, and fax remains available on the printed form. Electronic submission often confirms receipt faster, though either path routes to the same review process.

Fill in the member ID, diagnosis, requested drug, tried alternatives, and the prescriber's signature and contact details. Leaving out the clinical justification or the signature is a frequent cause of a request being delayed or returned for more information.
