How to appeal a Medicaid denial

Medicaid gives you something most coverage doesn’t: the right to keep your benefits running while you appeal — if you ask in time. The path runs through the plan first, then to a state fair hearing.

Medicaid is run by the states within a federal floor, and most enrollees are in managed-care plans. A Medicaid managed-care denial is appealed first through the plan’s internal appeal and then, if upheld, through a state fair hearing; fee-for-service Medicaid goes directly to the fair hearing. A defining feature is the right to continued benefits during the appeal when it’s requested before the change takes effect.

How appeals work at Medicaid

For Medicaid managed care, you must generally exhaust the plan’s internal appeal first — federal rules give you at least 60 days from the notice to file it (42 CFR 438.402) — and if the plan upholds the denial you can request a state fair hearing. Fee-for-service Medicaid goes straight to the fair hearing. States must allow at least 90 days to request a fair hearing (42 CFR 431.221). If you request the appeal before the effective date of the action, your benefits generally continue while the appeal is pending (42 CFR 431.230, 438.420). Exact deadlines and procedures vary by state.

What Medicaid commonly denies

  • Prior authorization missing or criteria not documented.
  • Medical necessity (CO-50-type) under the state’s coverage rules.
  • Reduction, suspension, or termination of an existing service or hours.
  • Level-of-care or eligibility-related determinations.

Is a Medicaid denial worth appealing?

Often worth appealing

Usually worth appealing — and acting fast matters twice over: the internal-appeal clock can be as short as 60 days, and requesting the appeal before the effective date can keep your benefits in place while it’s decided. Map the record to the state’s medical-necessity or coverage rule the denial cited. For a reduction or termination of an existing service, the continued-benefits right is the most valuable lever you have.

How to appeal a Medicaid denial

  1. 1

    File the plan’s internal appeal first

    For managed care, request the internal appeal within the deadline on the notice (at least 60 days federally) before going to a fair hearing.

  2. 2

    Request continued benefits in time

    If the denial reduces or ends a current service, ask for continued benefits before the effective date so coverage doesn’t lapse during the appeal.

  3. 3

    Take it to a state fair hearing

    If the plan upholds the denial, request the state fair hearing — states allow at least 90 days — and map the record to the state’s coverage rule.

Do I appeal to the plan or to the state?
For Medicaid managed care, you generally appeal to the plan first, then — if it’s upheld — request a state fair hearing. Fee-for-service Medicaid goes directly to the fair hearing.
