What to Do When Insurance Denies Your Medication

If your insurance denies a prescription, you have the right to appeal, starting with an internal appeal to your plan and often followed by an independent external review if the internal appeal fails. HealthCare.gov outlines this two-step appeals process for marketplace and most private health plans (HealthCare.gov). Comparing prescription prices can help cover the gap while your appeal is pending.

Read the denial letter first

Your insurer is required to tell you in writing why a prescription was denied. Common reasons include:

  • The drug requires prior authorization that was not obtained or approved.
  • The drug requires step therapy, and the required lower-cost drug was not tried first.
  • The drug is not on your plan's formulary.
  • The quantity or dosage prescribed exceeds plan limits.
  • The plan considers the drug not medically necessary based on the information submitted.

Understanding the exact reason determines what kind of appeal or fix is needed. If the issue is a missing prior authorization, sometimes a quick resubmission with more complete paperwork resolves it without a formal appeal at all.

The internal appeal process

An internal appeal asks your own insurance company to reconsider the denial. HealthCare.gov describes the process in three general steps: a claim is filed, the plan denies it and must explain why in writing, and then you file an internal appeal with any supporting documentation, such as a letter from your doctor (HealthCare.gov). Insurers must notify you of a decision within set timeframes, for example within 72 hours for urgent care cases, though standard timeframes are longer.

To file an internal appeal, you typically need to:

  1. Complete any forms your insurer requires, or write a letter including your name, claim number, and health insurance ID number.
  2. Include supporting documentation, especially a letter from your doctor addressing why the plan's stated reason for denial does not apply to your case.
  3. Submit within your plan's deadline, which is stated in your denial letter.
  4. Ask your state's Consumer Assistance Program for help if you get stuck, since many states offer free help navigating this process (HealthCare.gov).

The external review process

If your internal appeal is denied, you can generally request an external review, an independent review conducted by someone outside your insurance company. This step exists specifically to check whether the insurer's decision was fair and consistent with your plan's terms. KFF's consumer FAQ on marketplace appeals confirms that after your internal appeal, you have the right to ask for this independent review of the decision (KFF).

If you have Medicare Part D

Medicare Part D has its own multi-level appeals structure, separate from marketplace or employer plan appeals:

LevelWhat happensTypical deadline to file
Coverage determination / exception requestYour plan makes an initial decisionN/A (first step)
Redetermination (1st appeal)Plan reconsiders its own denial60 days from denial
Independent Review Entity (2nd appeal)An outside reviewer examines the case60 days from redetermination denial
Office of Medicare Hearings and Appeals (3rd appeal)Formal hearing review60 days from 2nd appeal denial
Medicare Appeals Council (4th appeal)Final administrative review60 days from 3rd appeal denial
Federal District Court (5th appeal)Judicial review, subject to a minimum dollar amount60 days from Council denial

CMS provides detailed guidance on requesting exceptions and appeals for Part D denials, including standard and expedited decision timeframes (CMS).

What to do while the appeal is pending

Appeals take time, and you may need your medication before a decision comes through. A few practical steps:

  • Ask your pharmacist for the cash price and compare it across nearby pharmacies. This can be a reasonable bridge, even though it usually will not count toward your deductible.
  • Ask your doctor about manufacturer patient assistance or copay card programs, which are separate from your insurance and may reduce your out-of-pocket cost while the appeal is processed.
  • Ask if an expedited appeal applies. If waiting could seriously harm your health, you may qualify for a faster review timeline.
  • Keep records of everything, including denial letters, call dates, names of representatives you spoke with, and copies of anything you submit.

Why denials happen more often than people expect

Prior authorization and step therapy requirements, which insurers use to manage costs, are common triggers for denials, especially for newer or more expensive drugs. Understanding how these tools work ahead of time can help you and your doctor prepare stronger documentation from the start. See our guides on prior authorization and step therapy for more background on why plans require these steps before covering certain medications.

When to bring in outside help

If your appeal is complex, or your state has a consumer assistance program, do not hesitate to ask for help. Many states offer free navigators or ombudsman services specifically for insurance appeals. Your employer's HR department, if you have employer coverage, may also be able to point you to resources. And your doctor's office, especially if they have a patient advocate or billing specialist, is often more experienced with this process than you might expect.

Frequently asked questions

What's the first thing I should do if insurance denies my medication?

Read the denial letter carefully for the specific reason. Then call your plan to confirm you understand it, and contact your doctor's office right away since they usually need to provide additional information or documentation for an appeal.

How long do I have to appeal a denied prescription?

Deadlines vary by plan type. Marketplace and most private plans require an internal appeal within a set window described in your denial letter, often 180 days, while Medicare Part D has its own shorter deadlines for each appeal level. Check your specific denial notice.

What is an external review?

An external review is an independent review of your appeal by someone outside your insurance company, available after you exhaust your plan's internal appeal process in most cases. HealthCare.gov outlines how to request one for marketplace and many private plans.

Can my doctor help with the appeal?

Yes, and in most cases your doctor's support is essential. A letter from your doctor explaining medical necessity, prior treatments tried, and why the prescribed drug is appropriate for you is usually the most important part of an appeal.

What should I do about the cost while my appeal is pending?

Ask your pharmacist about the cash price and compare it across pharmacies, since you may need to pay out of pocket temporarily. Also ask your doctor's office about manufacturer patient assistance programs that might help bridge the gap.
