To request coverage for a drug your plan doesn’t cover, your prescriber completes the Prime Therapeutics formulary exception form, attaches a supporting clinical statement, and submits it by electronic prior authorization, fax, or mail. Prime Therapeutics decides standard requests within 72 hours and expedited requests within 24 hours.1Centers for Medicare & Medicaid Services. Exceptions
Pick the Right Type of Request First
Prime Therapeutics uses different forms for different kinds of exceptions, and the wrong form slows everything down. Match your situation to one of these:2Prime Therapeutics. Request for Medicare Prescription Drug Coverage Determination
- Formulary exception — the drug isn’t on the plan’s formulary, or was removed during the plan year.
- Step therapy exception — the plan wants you to try a preferred drug first, but your prescriber believes that drug would fail or harm you.
- Quantity limit exception — you need more than the plan’s standard allowed amount.
- Tiering exception — the drug is covered but on a high-cost tier, and you want the lower copay of a preferred tier.
The clinical bar differs. For a tiering exception, the prescriber shows that preferred drugs for your condition would be less effective or cause adverse effects.3eCFR. 42 CFR 423.578 For a true formulary exception on a non-covered drug, the bar is higher: the prescriber must show that every covered alternative on any tier would be less effective or harmful for you specifically.
What Information the Form Requires
Have your insurance card out before anyone starts filling in fields. The form needs your full name, date of birth, member ID, and group number so it routes to the correct benefit plan.
Your prescriber’s office supplies the rest: the prescriber’s name, direct phone and fax, and 10-digit National Provider Identifier.4Centers for Medicare & Medicaid Services. National Provider Identifier Standard
Medication Details
Write in the exact drug name, strength (milligrams, milliliters, or other units), dosage form, and frequency. The prescriber adds the diagnosis using an ICD code plus a written description of the condition.5Prime Therapeutics. Choice Prescription Drug Prior Authorization Form – Coverage Exception
Clinical Justification
This is the section that decides the outcome. The prescriber’s supporting statement must explain why the requested drug is medically necessary and why formulary alternatives will not work for you.6Prime Therapeutics. Step Therapy Exemption Form For a step therapy exception, that means documenting that the required first-line drugs have been tried and failed, or that clinical evidence shows they would be ineffective or harmful.
Concrete documentation wins. If you tried a formulary drug and it failed, name it, note whether it was brand, generic, or over-the-counter, and give the dates.7Prime Therapeutics. Choice Prescription Drug Prior Authorization Form If you had an allergic reaction or serious side effect, say so. Lab results, imaging, chart notes, or peer-reviewed journal articles supporting the requested drug for your condition all strengthen the case, especially when the drug is being used outside its typical indication.
Where to Get the Correct Form
Prime Therapeutics publishes separate forms for commercial plans and Medicare Part D, and separate forms for coverage exceptions, step therapy exceptions, and Part B medical drugs. Your prescriber’s office should confirm the version matches your specific insurer before filling anything in.

How to Submit the Form
Electronic Prior Authorization
Prescriber offices can submit through CoverMyMeds, which integrates with many pharmacy and electronic health record systems. Offices without existing integration can sign up directly at CoverMyMeds.11Prime Therapeutics. Electronic Prior Authorization This is usually the fastest route because the data enters Prime Therapeutics’ system without manual intake.
Fax
Fax is still common for offices that don’t use electronic prior authorization. The number depends on the form. The commercial general prior authorization form directs submissions to 1-800-424-3260.12Prime Therapeutics. Prescription Drug Prior Authorization Form The Part B medical drug form uses 855-212-8110.9Prime Therapeutics. Part B Medical Drug Coverage Use the fax number printed on your specific form rather than assuming one works for everything, and keep the confirmation page as proof of the date and time.
Paper submissions go to Prime Therapeutics LLC, Attention: Clinical Review Department, 2900 Ames Crossing Road, Suite 200, Eagan, Minnesota 55121.9Prime Therapeutics. Part B Medical Drug Coverage Mail adds transit time and manual data entry on the receiving end, so turnaround runs longer than fax or electronic submission. Use it only when digital options aren’t available.
When to Expect a Decision
The clock starts when Prime Therapeutics has both the completed form and the prescriber’s supporting statement. For Medicare Part D plans, CMS requires decisions within 72 hours for standard requests and 24 hours for expedited requests.1Centers for Medicare & Medicaid Services. Exceptions You can ask for an expedited review if waiting the full 72 hours could seriously harm your health.
An incomplete submission pauses the clock. If Prime Therapeutics has to call the prescriber for missing clinical details, the timeline doesn’t restart until that information arrives. That is the single most common cause of delay. Fill in every field and attach supporting records the first time.
When a request is approved, both you and your prescriber get a written notice specifying the drug covered, the cost-sharing tier, and the duration. Approvals for Medicare Part D exceptions typically last up to one year, after which the prescriber may need to submit a new request to continue coverage.13PrimeTime Health Plan. Part D Prescription Drugs – Coverage Determinations, Appeals, Grievances
If the Request Is Denied
Read the denial letter carefully. For employer-sponsored plans governed by ERISA, the letter must state the specific reasons for the decision, point to the plan provisions it relied on, describe additional information that could strengthen the claim, and explain the appeal procedures and deadlines.14eCFR. 29 CFR 2560.503-1 – Claims Procedure If the denial was based on medical necessity, you are entitled to the clinical reasoning behind it, either in the letter or free of charge on request. Often the fix is straightforward: the prescriber provides the chart notes or prior-trial documentation that was missing from the first submission.
Internal Appeal
You have 180 days from the date you receive the denial to file an internal appeal.14eCFR. 29 CFR 2560.503-1 – Claims Procedure The appeal goes back to Prime Therapeutics, but a reviewer who was not involved in the original decision evaluates it. Address the specific gaps the denial letter identified. If a failed prior drug trial wasn’t documented, submit that now. If the prescriber can write a more detailed letter on why no formulary alternative works, include it.
For Medicare Part D plans, appeal timelines mirror the initial decision timelines: 72 hours for standard, 24 hours for expedited, measured from when the plan receives the appeal and supporting documentation.1Centers for Medicare & Medicaid Services. Exceptions
External Review
If the internal appeal is also denied, you can request an external review by an independent organization with no tie to your plan or Prime Therapeutics. Federal rules require a decision within 45 days of receipt for a standard review, or within 72 hours for an expedited review when your condition demands it.15eCFR. 45 CFR 147.136 – Internal Claims and Appeals and External Review The external reviewer’s decision is final and binding on the plan.
Getting Medication While You Wait
If you recently switched plans and are already taking a drug that isn’t on the new formulary, you may qualify for a transition fill. Medicare Part D plans must provide a temporary supply, typically a one-time 30-day fill, of non-formulary drugs or drugs subject to prior authorization, step therapy, or quantity limits during your first 90 days of enrollment. That buys time for your prescriber to work through the exception request or identify a formulary alternative.
Transition fill rules vary for commercial plans, so ask your plan or pharmacist if you need an immediate supply. For truly urgent situations, have your prescriber mark the exception request as expedited, which compresses the decision window to 24 hours.
