Why This Denial May Be Wrong

A medical necessity denial means your insurance company has decided that the treatment your doctor recommended is not required for your condition. This is the most common type of insurance denial, accounting for roughly 40% of all claim denials. Insurers use internal clinical guidelines to make this determination, often without reviewing your full medical record.

Importantly, your doctor disagrees with this decision. The doctor who prescribed or recommended the treatment believes it is medically necessary based on your specific clinical situation. The appeal process exists to challenge the insurer's determination using your actual medical evidence.

Your Legal Rights

Under the Affordable Care Act (ACA), you have the right to appeal any denial of coverage. For medical necessity denials, Section 2719 of the Public Health Service Act requires insurers to provide you with a clear explanation of why the claim was denied and instructions for how to appeal. You have at least 180 days to file an internal appeal. If the internal appeal is denied, you have the right to an independent external review by a third party who has no relationship with your insurer. Your state may have additional protections that exceed federal requirements.

How to Appeal: Step by Step

  1. 1Request the complete denial letter and your insurer's clinical policy guidelines for the denied service.
  2. 2Ask your doctor for a letter of medical necessity explaining why this treatment is required for your specific condition.
  3. 3Gather supporting documentation: medical records, test results, treatment history, and peer-reviewed studies.
  4. 4Write your appeal letter citing the specific clinical evidence that supports medical necessity.
  5. 5Reference applicable regulations: ACA Section 2719, your state insurance code, and the insurer's own clinical policy.
  6. 6Submit via certified mail with return receipt requested. Keep copies of everything.
  7. 7Follow up at 30 days if you haven't received a response.

FAQ

What counts as medical necessity?

Medical necessity means the treatment is appropriate for your diagnosis, follows accepted medical standards, and is not primarily for convenience. Your doctor's clinical judgment is the primary determinant.

Can I appeal if I already received the treatment?

Yes. You can appeal retroactive denials. The same appeal process applies whether the treatment has been performed or is being pre-authorized.

How long does the appeal process take?

Insurers typically have 30-60 days to respond to an internal appeal. Expedited appeals for urgent situations must be resolved within 72 hours.
