You hand over a prescription you have filled a dozen times and the pharmacist says the plan needs approval first. Nobody at the counter can tell you how long it will take. You are holding up a queue.
This guide is about what has actually happened, and what to do in the next hour.
The three restrictions
Plans use three tools to manage what they pay for. They look similar at the counter and they are not the same thing.
Prior authorization means the plan will not pay until your prescriber justifies the prescription. It is the most common and usually the quickest to clear.
Step therapy means the plan wants you to try something else first — normally a cheaper drug for the same condition. If you have already tried it, that history can be submitted and the step waived.
Quantity limits mean the plan will pay for a set quantity over a set period. If your dose is higher than the standard, or your prescriber wants a ninety-day supply where the plan allows thirty, this is what you have run into.
All three are legitimate and all three are appealable.
In the first hour
Ask for the written notice. The pharmacy must give you a notice explaining that the drug was not covered and telling you how to contact the plan. Ask for it by name; it is not always offered.
Telephone the plan yourself, the same day. The number is on your plan card. Ask exactly three things: what is required, who has to supply it, and what the decision deadline is. Write the answers down with the date and the name of the person you spoke to.
Telephone the prescriber’s office and speak to the person who handles prior authorizations. Every practice has one, and it is rarely the doctor. Tell them the plan’s name, the drug, and what the plan told you it needs. This one telephone call is usually what determines whether this takes two days or two weeks.
Ask the pharmacist for an emergency supply if you will run out. In many circumstances a short supply can be dispensed while the decision is pending. It is not guaranteed, and it is always worth asking.
What your prescriber should send
A prior-authorization request is a clinical argument, and the strong version of it says three things: what has been tried, what happened, and why this drug is the right one now.
If you have tried the plan’s preferred alternative and it did not work, or you could not tolerate it, say so specifically. “Patient tried X in 2023, discontinued due to Y” does more work than a page of general reasoning.
If the plan’s preferred alternative is contraindicated for you — because of another condition or another medication — that should be stated plainly. Plans have to allow for it.
If you have been stable on this medication for years, that is itself an argument, and it is one that plans accept.
The deadlines
Decisions on drug requests have deadlines, and there is a faster track when waiting would seriously harm your health. Your prescriber can ask for the expedited version, and if they support the request the plan must use the shorter clock.
Ask for the expedited route if delay would genuinely cause harm. Do not ask for it routinely — it is a real mechanism and it works better when it is used for what it is for.
Note the date you were refused. Every deadline that follows is counted from it, and losing track of that date is the most common way people end up out of time.
If the answer is no
A refusal is the beginning of a process, not the end of one.
You have the right to a redetermination by the plan, and if that fails, to review by an independent organization that has no relationship with the plan. There are further levels beyond that. Denials are overturned at every level more often than people expect, largely because the first refusal is frequently a paperwork outcome rather than a clinical one.
The separate guide on appeals sets out the levels and the timescales. Two things matter more than the detail: start immediately, and put everything in writing even when you also telephone.
Preventing it next year
Most of this is avoidable, once a year, in about half an hour.
When you compare plans in the autumn, do not stop at whether your drugs are on the formulary. Check whether any of them carries prior authorization, step therapy or a quantity limit on that plan. The Medicare Plan Finder at Medicare.gov shows these restrictions, and so will any adviser worth sitting with.
If a medication you depend on carries a restriction on every plan available to you, that is worth knowing in October rather than discovering in January. It does not necessarily change your choice, but it lets you get the paperwork started before you need the drug.
One thing to hold on to
None of this is a judgment about you or your prescription. It is a payment rule, applied by a computer, at a counter, in front of other people.
The pharmacist is not refusing you. The plan has a process, the process has deadlines, and the deadlines are on your side more often than not — provided somebody starts the clock. That somebody is usually you, with one telephone call to the prescriber’s office.
General information, not advice
This guide describes how Medicare generally works. It is not advice about your situation, and rules, dates and figures change — verify anything that matters to a decision against Medicare.gov, 1-800-MEDICARE, or your State Health Insurance Assistance Program, all of which are free.
