Medicare Appeal Letter - How to Write + Template

Medicare has denied a claim for a medical service, treatment, equipment, or prescription drug that you or your doctor believes should be covered. Here are the most common denial scenarios and how to appeal them: - Medical necessity denial (Part A or B): Medicare determined that a service your doctor provided or ordered was not medically necessary according to Medicare's National Coverage Determinations (NCDs) or Local Coverage Determinations (LCDs). This commonly occurs with advanced diagnostic imaging, certain surgical procedures, extended inpatient hospital stays (especially when Medicare believes the service could have been provided on an outpatient basis), skilled nursing facility stays beyond what Medicare considers medically necessary, and home health services. Your appeal should include a detailed letter from your treating physician explaining why the service was medically necessary for your specific condition, supported by your medical records and any relevant medical literature. - Prescription drug denial (Part D): Your Medicare Part D plan denied coverage for a prescription drug, typically because the drug is not on the plan's formulary, the plan requires prior authorization that was not obtained, quantity limits or step therapy requirements were not met, or the plan considers a generic alternative appropriate. Part D appeals follow a specific process: first you request a coverage determination from your plan, then an internal appeal (redetermination), then an external review by an Independent Review Entity (IRE). For urgent medication needs, you can request an expedited determination that must be decided within 24 hours. - Skilled nursing facility or rehabilitation denial: Medicare denied continued coverage at a skilled nursing facility, inpatient rehabilitation facility, or home health agency, determining that you no longer need skilled care or that you are not making sufficient progress. These denials are particularly common and often incorrect - Medicare requires that you need skilled nursing or therapy services on a daily basis, but the Jimmo v. Sebelius settlement clarified that Medicare cannot deny coverage solely because a patient is not improving, as long as skilled care is needed to maintain function or prevent decline. - Durable medical equipment denial: Medicare denied coverage for a wheelchair, hospital bed, CPAP machine, prosthetic device, or other durable medical equipment (DME), often citing lack of medical necessity documentation or failure to meet specific coverage criteria. DME coverage requires a physician's order, documentation of medical necessity, and in many cases a face-to-face encounter with the prescribing physician. - Hospital observation vs. inpatient admission: You received hospital care classified as outpatient observation rather than inpatient admission, which affects your Medicare coverage, particularly your eligibility for subsequent skilled nursing facility coverage (which requires a qualifying 3-day inpatient stay). The MOON (Medicare Outpatient Observation Notice) should have been provided, and you may be able to appeal the classification. - Medicare Advantage plan denial: Your Medicare Advantage (Part C) plan denied a service that would be covered under Original Medicare. MA plans must cover all services that Original Medicare covers, though they may have different rules for referrals, prior authorization, and network restrictions. If your MA plan denies a service, you can appeal through the plan's internal process and then to an independent external reviewer.
