Prior Authorization for Psychiatric Medications: How to Get Through It

Prior authorization is your health plan's requirement that your prescriber justify a medication before the plan will pay for it. For psychiatric medications, the fastest route through it is usually the same: your prescriber submits the plan's form with your diagnosis and medication history, you track the request, and if it is denied you appeal with the specific reasons the plan gave.

In New York, state law sets deadlines for most fully insured plans, including a 72-hour clock (24 hours when your health is in serious jeopardy) for requests to override step therapy, and it treats a missed deadline as an override. Those state rules do not reach self-insured employer plans, Medicaid fee-for-service or Medicare, which follow their own rules. This guide explains which rules apply to you and what to do at each step. It is general information, not tax or legal advice.

Prior authorization, step therapy and quantity limits: what each means

Plans use several tools that all feel like "the pharmacy won't fill it." They are different, and the fix for each is different. Medicare's drug program, for example, lets you or your prescriber ask the plan to waive a step therapy, prior authorization or quantity limit rule through an exception request.

Your pharmacy's rejection message often names the rule. Ask the pharmacist to read you the exact reject reason, because "needs prior auth" and "quantity limit exceeded" lead to different paperwork.

First, find out which rules govern your plan

The single most useful fact is what kind of plan you have, because it decides which deadlines and appeal rights apply. Your insurance card and plan documents usually say whether the plan is fully insured, self-funded by your employer, Medicare, or Medicaid managed care.

Medicaid managed care plans follow New York's step therapy law, but Medicaid managed care also has a separate rule under state Social Services Law, so ask your plan which process it uses.

Step by step: getting a prior authorization approved

1. Confirm the reason for the rejection at the pharmacy and ask whether a covered alternative exists at the same strength.
2. Tell your prescriber's office the exact rule (prior authorization, step therapy, quantity limit or non-formulary) and the plan's name and member ID.
3. Your prescriber submits the request, usually through an electronic portal or the plan's form. Under New York's step therapy law, it is the health care professional who must submit the supporting rationale and documentation.
4. Write down the date and time the request went in and any reference number. New York's clocks start when the plan receives the necessary information, so the submission date matters.
5. Call the plan after one business day to confirm the request is complete. For a New York step therapy override that already includes the prescriber's supporting rationale and documentation, the plan must decide within 72 hours (24 hours if urgent) even if it asks for more information.
6. Once approved, ask how long the approval lasts so you are not surprised at the next refill.

What makes a request strong

Plans approve requests that answer their criteria directly. You can help your prescriber by having this ready:

• A list of every medication tried for the same condition, with approximate dates, doses and why each was stopped (side effects, no benefit, partial benefit). A separate guide covers how to prepare your medication history.
• Any medical condition that makes the plan's preferred drug risky for you, such as a heart condition, pregnancy, or a past serious reaction.
• Whether you are currently stable on the requested medication, including on a previous plan.
• Records from a previous prescriber if your earlier trials happened elsewhere.

You may also ask the plan, in writing, for the clinical review criteria it uses for step therapy override decisions; New York plans must provide them on request.

New York's step therapy override law, in plain terms

New York requires plans covered by Insurance Law 4903 to grant a step therapy override when your prescriber's documentation shows any of these:

• The required drug is contraindicated or likely to cause an adverse reaction.
• The required drug is expected to be ineffective based on your known clinical history.
• You have already tried the required drug, or one in the same class or with the same mechanism, and it was stopped for lack of benefit, reduced effect or an adverse event.
• You are stable on a drug your prescriber selected for the condition, although the plan may still require you to try an AB-rated generic equivalent of a brand-name drug first.
• The required drug is not in your best interest because it would create a significant barrier, for example to sticking with treatment or by worsening another condition.

Three details matter in practice. First, the plan must decide within 72 hours of receiving the supporting documentation, or 24 hours when your health is in serious jeopardy. Second, if the plan misses that deadline on an initial override request, the override is deemed granted. Third, an approved override must give immediate coverage, lasting for the lesser of the evidence-based treatment duration or twelve months.

Some limits are worth knowing. The law does not stop a plan from requiring you to try more than one preferred drug, and the regulator has said that a trial using samples or manufacturer coupons may not establish that you are stable on a drug. Not taking a drug as directed is not the same as the drug failing, so be candid with your prescriber about how you actually took earlier medications.

Medicare Part D: exceptions and the transition supply

In Medicare drug plans, a request to waive prior authorization, step therapy or a quantity limit is called an exception, which is a type of coverage determination. You, your prescriber or your representative can ask, but your prescriber must send a supporting statement, and the plan's clock runs from that statement: 24 hours for an expedited request and 72 hours for a standard one.

If you are new to a plan, or you switched plans, Part D plans must give a one-time temporary supply of a non-formulary drug or a drug that needs prior authorization or step therapy, of at least a month's supply, during your first 90 days of coverage. That transition fill exists so treatment is not interrupted while the exception is decided. Ask the pharmacist to run it as a transition fill if the claim rejects.

Medicare Open Enrollment runs October 15 to December 7, with changes effective January 1. If your current plan keeps imposing prior authorization on a medication you depend on, compare plans' formularies for that drug before the deadline.

When the answer is no: appeals

A denial is not the end. Read the denial letter closely; it should state the reason and the criteria used, and your appeal should answer that reason point by point. The guide to appealing a denied mental health claim walks through letters and records in more detail.

For a non-formulary drug, a New York external appeal is decided within 72 hours, or 24 hours when expedited. For a non-formulary drug in a non-grandfathered individual or small group plan, if the plan does not require an internal appeal, you can request an external appeal after the first denial. External reviewers consider the plan's criteria but are not required to uphold them.

Bridging the gap while you wait

The riskiest moment is running out of a medication while paperwork is pending. Plan ahead and keep your prescriber informed.

• Request refills early enough that a prior authorization can be processed before your last dose.
• If a gap looks likely, tell your prescriber. Some psychiatric medications cause discontinuation symptoms if stopped suddenly, and only your prescriber can decide whether a short bridge, a temporary alternative or a different strength is appropriate. Never stop or swap a medication on your own.
• Ask the pharmacy whether a smaller fill is covered while the request is pending.
• Check whether the manufacturer offers a patient assistance program; Medicare's own guidance suggests checking whether the company that makes your drug offers help paying for it.
• Paying cash with a discount card can bridge a short gap, but for people with Medicare those purchases do not count toward the plan's deductible or out-of-pocket maximum. Manufacturer copay coupons generally cannot be used for drugs paid for by Medicare or Medicaid.

Cost strategies are covered in the companion guide on lowering prescription costs for psychiatric medications.

A worked example

Consider a patient in a fully insured New York plan who has been stable on a brand-name antidepressant under a previous employer's plan. The new plan requires a generic SSRI first. The prescriber files a step therapy override, citing that the patient is stable on the current drug and listing two earlier SSRI trials that were stopped for side effects. The patient notes the submission time. Because the request includes the supporting rationale, the plan has 72 hours to decide; if it says nothing, the override is deemed granted. If it denies, the patient files an internal appeal with the denial letter and the prescriber's notes, then requests an external appeal if needed.

The same patient in a self-funded employer plan would not have the New York override rule, so the prescriber would use the plan's own exception process and the patient would rely on federal claims deadlines.

Questions to ask your plan and your prescriber

• Is my plan fully insured or self-funded, and which appeal process applies?
• Exactly which rule is blocking this fill, and which drugs does the plan prefer for this condition?
• When did you receive the request, and is anything missing?
• How long will an approval last, and will I need to renew it?
• Can you send me the clinical criteria used for this decision?
• For my prescriber: is there a covered alternative that is clinically reasonable for me, or is an override the better route?

If you are unsure whether a change in medication is the real question, the guides on ongoing medication management and on generic versus brand-name psychiatric medications can help you prepare for that conversation. All guides in this series are collected in the guide to choosing psychiatric care.

How this works with Dr. Lewis's practice

Dr. Lewis and all of the practice's practitioners are out of network with all insurance plans, including Medicare and Medicaid, and payment for visits is due at the time of service. Prior authorization concerns your pharmacy benefit, which is separate from how visits are paid, so it is worth asking how prescription paperwork is handled. The free discovery call covers questions about care options, scheduling and insurance. Details on visit payment and superbills are on the insurance and payment page, and the practice's approach to prescribing is described on the medication management page.

Frequently asked questions

Can I submit a prior authorization myself?

Usually not. Plans need clinical information from the prescriber, and New York's step therapy law requires a health care professional to submit the supporting rationale. You can still call the plan to confirm the request arrived, ask what is missing and track deadlines.

Does a prior authorization approval last forever?

No. Many approvals expire and must be renewed. In New York, an approved step therapy override lasts for the lesser of the evidence-based treatment duration or twelve months. Ask the plan for the end date when you are approved.

My plan changed its formulary in the middle of my treatment. What can I do?

Ask your prescriber to file an exception or override, citing that you are stable on the current medication. In Medicare drug plans, current enrollees affected by formulary changes are included in the transition process, so ask the pharmacy about a transition fill.

Will using a manufacturer savings card get around prior authorization?

Usually not. A copay card lowers what you pay once the plan covers a drug; it does not replace the plan's approval. Coupons also generally cannot be used with Medicare or Medicaid drug coverage.

What if the medication is urgent?

Ask your prescriber to mark the request as expedited and explain why. New York plans must decide a step therapy override within 24 hours when your health is in serious jeopardy, and Medicare plans decide expedited exceptions within 24 hours of the prescriber's statement. If you are in crisis, call or text 988 or go to an emergency room.

Who can help me if my plan ignores the deadlines?

For New York fully insured plans, a missed step therapy deadline counts as an override, and you can contact the New York Department of Financial Services about external appeals and complaints. For Medicare, call 1-800-MEDICARE or your local State Health Insurance Assistance Program.
