My drug was removed from the formulary. How do I get an exception?
A formulary exclusion is not a medical-necessity decision, so the route is a formulary exception request with a prescriber statement that the covered alternatives are not appropriate for you, filed under the plan's exception process. ACA plans must decide a standard request within 72 hours and an urgent one within 24; employer plans follow ERISA's pre-service timeframes.
What to do, in order
- Step 1
Get the exception form and the alternatives list
Ask the plan or PBM for its formulary exception form and the list of covered alternatives it expects you to try. The exception request has to answer that list drug by drug.
- Step 2
Prescriber statement
One page from the prescriber: diagnosis, the drugs on the alternatives list you have tried or cannot take (with dates, doses and what happened), why the excluded drug is medically necessary for you, and the clinical harm expected from switching. Attach the chart notes that show it.
- Step 3
Ask for a transition supply while it is decided
Most plans provide a transition fill for a drug you were already taking when the formulary changed. Ask for it by name at the pharmacy counter and in the request.
- Step 4
Appeal a denial as a pre-service claim
A denied exception is an adverse benefit determination. Appeal in writing, ask for the criteria applied and the reviewer's credentials, and if the internal appeal fails go to external review; for drug exceptions on ACA plans the external reviewer must decide within 72 hours standard.
The deadline that applies
ACA individual and small-group plans: standard exception decided within 72 hours, expedited within 24 hours, and the external review of an exception denial within 72 or 24 hours (45 CFR 156.122(c)). ERISA plans: 15 days pre-service, 72 hours urgent (29 CFR 2560.503-1). Medicare Part D: 72 or 24 hours (42 CFR 423.578). The denial letter controls the appeal deadline.

Related questions
Is a formulary exclusion the same as a denial?
It becomes one when your claim rejects. Ask for the written notice and use the exception process; that is the appeal route the plan has to provide.
What if the alternative is a different drug class?
The prescriber statement should say why the class is inappropriate for you, not just the molecule. Reviewers look for a clinical reason, not preference.
Can the plan make me try the alternatives first?
It can require a documented reason not to. Prior trials, contraindications, interactions and stable control on the current drug are the usual reasons.

Upload the denial letter. A senior reviewer reads it within 24 hours and tells you in writing whether it can be appealed and how. $0 upfront, 10% of what is recovered, nothing if we do not recover. Not a law firm.
