In short
- Your appeal path depends on your type of coverage.
- Medicare, Medicaid, Marketplace, and job plans each have their own steps.
- Look at your card or denial letter to find your type.
What this means
Your appeal rules depend on your health coverage type. If you have a Medicare Advantage plan (HMO, PPO, PFFS, MSA, Cost Plan, or Health Care Prepayment Plan), follow the Medicare Advantage path under 42 CFR Part 422, Subpart M [1]. If your prescription drug plan (Part D, standalone or in an MA plan) denied a drug, use the Part D path under 42 CFR Part 423, Subpart M [2]. If you have Medicaid coverage or a Medicaid health plan, you may request a State fair hearing after the adverse benefit determination is upheld, per § 438.408 [3]. If you bought coverage through HealthCare.gov or a state marketplace, or have any individual plan, you must use an ACA internal appeal followed by external review, with only one level of internal appeal allowed [4]. If your coverage comes through a private employer, follow the ERISA claims procedure, which requires a reasonable opportunity to appeal to a named fiduciary and a full and fair review [5]. If you received a surprise out-of-network medical bill (e.g., emergency care, in-network hospital, air ambulance), you may file a No Surprises complaint and also appeal through your plan [6]. Each path has specific deadlines and steps, and rules vary by plan type.
