The Aetna CVS Caremark Medicare tier exception form is a one-page request your prescriber submits to move a drug from a higher-cost tier to a lower one on your Aetna Medicare Part D plan. If the plan approves it, you pay the copayment or coinsurance of the lower tier when you fill the prescription. The form itself is short. The clinical statement your prescriber writes on it is what decides the outcome.
Who Files the Form
Federal rules give every Medicare Part D enrollee the right to ask for a tiering exception, and you can file the request yourself or have your prescriber file it for you.1eCFR. 42 CFR 423.578 – Exceptions Process In practice, the form needs a prescriber’s signature and a clinical justification, so most requests start at the doctor’s office.
One limitation to know upfront: specialty-tier drugs are generally not eligible for a tiering exception. Since January 1, 2022, Part D sponsors have been allowed to design their exception process so drugs on a specialty tier cannot be moved to a non-specialty tier.1eCFR. 42 CFR 423.578 – Exceptions Process If your drug is on Aetna’s specialty tier, this form is not the right path.
What the Form Asks For
The form has three sections: patient information, prescriber information, and the medication request. Gathering everything before the office starts typing prevents the back-and-forth that slows a request down.
Patient Information
You’ll need your full name, Aetna member ID number, mailing address, home telephone number, gender, and date of birth.2Aetna. Aetna CVS Caremark Medicare Tier Exception Form Check that the member ID matches your current card. Plans sometimes issue new IDs at the start of a plan year, and an outdated number can delay processing.
Prescriber Information
Your prescriber enters their full name along with their NPI and DEA numbers.2Aetna. Aetna CVS Caremark Medicare Tier Exception Form Leaving either field blank risks a rejection on a technicality.
Medication Request
The form asks for the drug name, strength, route of administration, and dosing frequency.2Aetna. Aetna CVS Caremark Medicare Tier Exception Form Be precise. “Eliquis 5mg oral twice daily” is far better than “Eliquis as directed.” Vague entries give the reviewer a reason to send the form back.
The Prescriber’s Supporting Statement
Most tier exception requests succeed or fail on the supporting statement. The form has a dedicated area for the prescriber to explain why the requested drug is medically necessary and why preferred alternatives aren’t appropriate, and additional pages or clinical documentation can be attached.2Aetna. Aetna CVS Caremark Medicare Tier Exception Form
Under federal rules, the statement must establish at least one of the following: that the preferred drugs on a lower tier would not be as effective for you, that they would cause adverse effects, or both.1eCFR. 42 CFR 423.578 – Exceptions Process A generic note that the patient needs the drug almost never works. Specific clinical detail does:
- Prior drug failures. If you tried a lower-tier medication and it didn’t work, the prescriber should name the drug, the dates you were on it, and the specific outcome, such as continued symptoms or lab values that didn’t improve.
- Side effects from alternatives. If a preferred drug caused a documented adverse reaction, the statement should describe what happened and when.
- Contraindications. If another condition or medication makes a preferred drug unsafe, the prescriber should explain the interaction or clinical risk.
A reviewer wants to see that the prescriber considered every reasonable lower-tier option, not just the most obvious one. Attaching chart notes, lab results, or records of a prior adverse reaction strengthens the case.
How to Submit It
The fastest route is fax. The number printed on the form is 1-800-408-2386.2Aetna. Aetna CVS Caremark Medicare Tier Exception Form Fax creates an immediate transmission record, which matters if a dispute later arises about when the plan received the request.
Aetna also offers an online option through the member portal, and prescribers can call the Customer Care number on your ID card to start a request by phone.3Aetna Medicare. Prescription Drug Information and Resources Even if you submit online, your prescriber may still need to fax the supporting statement, since the plan cannot act without the clinical justification.
Mail works too, but it is the slowest option. The federal decision clock does not start until the plan actually receives the supporting statement, so every day in transit is a day you wait.
How Long the Decision Takes
Once the plan has both the form and the supporting statement, federal timelines take over. A standard tier exception decision must be issued in writing within 72 hours. If your health could be seriously harmed by waiting, your prescriber can request an expedited review, which requires a decision within 24 hours. The plan may give its initial decision by phone, but a written notice must follow within three calendar days.4Centers for Medicare & Medicaid Services. Exceptions
If approved, the plan adjusts your cost-sharing so you pay the lower-tier amount at the pharmacy. The approval generally lasts through the end of the current plan year. If you stay on the same Aetna Medicare plan the next year, you may need to request the exception again, because plans are not required to carry approvals over automatically.
Getting Your Drug While You Wait
Waiting 72 hours is manageable if you still have pills. If you don’t, ask about a transition supply. Part D plans must provide temporary coverage to prevent interruptions in therapy while an exception request is being processed, typically a one-time 30-day fill. If the request or any appeal hasn’t been resolved by the time that supply runs out, the plan must extend the transition period on a case-by-case basis so you aren’t left without medication.5Centers for Medicare & Medicaid Services. Medicare Prescription Drug Benefit Manual Chapter 6 Call the Customer Care number on your member ID card to arrange one.
If Aetna Denies the Request
A denial is not the end. Medicare Part D has a five-level appeals process, and most tier exception disputes that have merit are resolved at the first or second level.
Level 1: Plan Redetermination
You, your representative, or your prescriber must ask for a redetermination within 65 days of the date on the denial notice. The plan reviews the request again, and this is the opening to add clinical documentation the first submission lacked. A standard benefits appeal gets a decision within 7 days; an expedited appeal, within 72 hours.6Medicare. Appeals in a Medicare Drug Plan If the original supporting statement was thin, a more detailed letter at this stage often reverses the outcome.
Level 2: Independent Review
If the plan upholds its denial, you have 60 days to ask an Independent Review Entity for a reconsideration. The IRE has no connection to Aetna and reviews the clinical evidence on its own.6Medicare. Appeals in a Medicare Drug Plan
Beyond Level 2, the process continues to an administrative law judge, then the Medicare Appeals Council, and finally federal court, each with a 60-day filing window and, at the later stages, minimum dollar thresholds.6Medicare. Appeals in a Medicare Drug Plan Those stages are uncommon for a single drug’s cost-sharing dispute.
Why Requests Get Denied
Common reasons include a supporting statement that is too vague, missing prescriber identifiers like the NPI or DEA number, requesting that a specialty-tier drug be moved to a non-specialty tier, and failing to explain why each preferred alternative on the formulary is inappropriate rather than just one of them. The denial letter will spell out the specific reason the plan gave, which tells you exactly what a resubmission or appeal needs to address.
