My prior authorization renewal is stuck in a fax loop with CVS Caremark. How do I break it?
The loop is between the prescriber's fax and the PBM's fax queue, and you can break it from your side by getting the case number, the exact missing item and the receipt date from Caremark, then having the prescriber resubmit by electronic prior authorization instead of fax. While it is pending, ask for a transition or continuity fill.
What to do, in order
- Step 1
Get three facts from the PBM
Call Caremark and write down the PA case number, the exact criteria item they say is missing, and the date they received the last submission. Ask them to read the note on the case. Most loops are one missing field, not a decision.
- Step 2
Resubmit by ePA, not fax
Ask the prescriber's office to resubmit through electronic prior authorization (CoverMyMeds, Surescripts, or the EHR's ePA module). ePA requests carry a case number and a timestamp and are far harder to lose than a fax.
- Step 3
Ask for a transition fill
Many commercial plans allow a short continuity-of-therapy override when a renewal is stuck for a drug you are already on. Ask Caremark for it by name and ask the pharmacy to run the claim with the override code they give.
- Step 4
Force a written decision
If nothing moves, ask Caremark in writing for a decision with appeal rights. A request that is neither approved nor denied within the plan's stated time is treated as denied on most plans once the clock runs, and the written denial is what starts the formal appeal. If it is an employer plan, HR's benefits contact can escalate to the plan's account team, which is usually the fastest lever.
The deadline that applies
Employer (ERISA) plans must decide a non-urgent pre-service request within 15 days, one 15-day extension allowed, and an urgent one within 72 hours (29 CFR 2560.503-1). Medicare Part D coverage determinations are due within 72 hours standard or 24 hours expedited (42 CFR 423.568). Marketplace and other ACA plans must decide a standard formulary exception within 72 hours (45 CFR 156.122). Your own appeal window runs from the written denial; the letter controls.
Calculate your date →Documents to gather
- Every fax confirmation sheet and ePA case number
- The PA criteria for the drug (ask Caremark for the document)
- The prescriber's chart note showing the criteria are met
- The pharmacy rejection with the code

Related questions
Can I submit the prior authorization myself?
On most plans the prescriber must submit clinical criteria, but you can send the supporting records and you can always file the appeal once there is a written denial.
Will Caremark tell me what is missing?
Usually yes if you ask for the case note by case number. Ask specifically which criterion is unmet, not whether it is pending.
Is a stuck renewal appealable?
Once the plan's decision time has passed without a decision, yes. Ask for the written denial or state in writing that you treat the request as denied and are appealing.
