Caremark Prior Authorization Fax: Form, Number and Checklist
Find the right Caremark prior authorization form and fax route. Check the plan, prescriber requirements, attachments and privacy safeguards.
The fax number on CVS Caremark’s published Global Prior Authorization form is 1-888-836-0730. Use it only when the prescriber confirms that form applies to the patient’s plan and request.
We checked the official non-Medicare Global form on October 7, 2026; its printed revision is March 18, 2024. Re-check the official page and the current request the day you send. A plan or drug-specific form may direct the office elsewhere.
Verify the form before sending
| Published form | Fax on the form | Send |
|---|---|---|
| CVS Caremark Global Prior Authorization, non-Medicare | 1-888-836-0730 | Open HIPAA fax to Caremark |
If the office received a different prior authorization request, compare its destination and requirements with the plan’s instructions. Do not send a coverage appeal, pharmacy claim or unrelated insurer’s precertification form to this number just because it concerns a prescription.
Build the prescriber packet
The Global form requests patient and plan identifiers, prescriber details, medication information, diagnosis and supporting clinical information. The prescriber completes the attestation and required signature/date. Follow the requested attachments rather than sending an entire chart.
Before uploading, check the packet as a document:
- Is the form complete, including any pages after the signature page?
- Can the recipient read the member ID, prescriber contact details and medication information?
- Are the supporting pages in the order referenced by the request?
- Are signatures and dates visible, without a scanner cutting off the page edges?
- Does the fax destination match the form being used today?
Keep an exact copy of the submitted packet in the office’s approved records system. That makes it easier to respond if the reviewer asks for a missing attachment or a clearer page.
Use the HIPAA flow for PHI
Prior authorization paperwork can contain protected health information. Use SingleFax HIPAA fax and complete the electronic BAA before uploading PHI. The Caremark link above opens that flow with the destination filled in. Confirm that your organization is authorized to transmit the information and check the recipient again before sending.
Use a cover sheet with the prescriber office’s callback information, department and page count. Keep clinical details off the cover when they belong in the request itself. A confidentiality statement can help identify a misdirected fax, but it does not replace recipient verification or a BAA.
HIPAA sends have their own quote and pricing in checkout. Pay-on-success describes the transmission charge; it does not depend on whether Caremark approves the medication.
After transmission
Save the receipt and follow the request through the plan’s or prescriber’s normal status channel. If more information is requested, identify which pages are needed and confirm where to send the response before transmitting it.
For an urgent clinical situation, the prescriber should follow the plan’s urgent-review instructions and assess the appropriate clinical next step. Do not treat a fast fax result as an authorization decision or a substitute for that assessment.
