Alzheimer's Care Insurance Claim Denied? How to Appeal

Insurance denials for Alzheimer's care affect thousands of families each year, often at the most vulnerable moments in a loved one's decline. Whether the denial involves memory care facilities, cognitive testing, Alzheimer's medications, or care management services, the refusal is rarely the final word. Alzheimer's disease claims use ICD-10 codes G30.0 (early onset), G30.1 (late onset), G30.8 (other), and G30.9 (unspecified). Under the ACA Essential Health Benefits framework, diagnostic services, physician visits, and medication management for Alzheimer's disease are covered services. The Alzheimer's Association Care Practice Guidelines and the American Academy of Neurology (AAN) Practice Guidelines both establish that regular neuropsychological monitoring and structured care programs are medical services — not custodial. This guide covers why insurers deny Alzheimer's care claims and the exact steps to fight back.

Why Insurers Deny Alzheimer's Care Claims

Alzheimer's care denials fall into several distinct categories:

• "Custodial care" exclusion — The most common denial for memory care facility claims; insurers draw a line between skilled nursing care (covered) and custodial care (assistance with bathing, eating, and daily activities) and classify memory care as the latter, ignoring the medical complexity of caring for Alzheimer's patients
• Not medically necessary — Insurers argue cognitive assessments, care management visits, or medications are not clinically required, despite Alzheimer's Association and AAN guidelines to the contrary
• Cognitive testing frequency denied — Claims for neuropsychological assessments beyond once every few years are denied, despite guidelines recommending regular monitoring to track progression and adjust care
• New disease-modifying drug denials — Lecanemab (Leqembi) and donanemab received FDA approval for early Alzheimer's; some commercial payers deny these drugs as "experimental" despite FDA approval and CMS coverage determinations
• Long-term care (LTC) benefit trigger not met — Insurers dispute whether the policyholder has met the ADL (Activities of Daily Living) impairment threshold or cognitive impairment standard required to trigger LTC benefits
• Documentation insufficient — Medical records, physician letters, or formal cognitive assessments do not meet the insurer's submission requirements

How to Appeal an Alzheimer's Care Denial

Step 1: Understand the Specific Type of Denial

Read the denial letter carefully to identify whether the denial is based on the custodial care exclusion for a memory care facility, "not medically necessary" for cognitive testing or medications, LTC benefit trigger not met, documentation gap, or experimental drug classification. Each requires a different argument — a single letter cannot effectively address all of these simultaneously.

Step 2: Reframe Memory Care as Skilled Medical Care

If the denial cites the "custodial care" exclusion, your appeal must establish that Alzheimer's memory care involves skilled medical services beyond basic custodial support. These include complex polypharmacy management requiring nursing oversight, behavioral health interventions for agitation, wandering, and psychosis, medical complication monitoring (aspiration risk, pressure injuries, infections), structured evidence-based dementia care programs with clinical outcomes data, and 24-hour safety supervision for patients with documented risk behaviors. The Alzheimer's Association Care Practice Guidelines directly support this argument — cite them explicitly.

Step 3: Document ADL Impairment Formally for LTC Triggers

If the denial involves an LTC benefit trigger, obtain formal ADL assessments from your neurologist or geriatrician, a licensed social worker or care manager, and the memory care facility's admissions assessment. Document impairment in at least the number of ADLs required by your policy (typically 2–3 of: bathing, dressing, toileting, transferring, continence, eating). Include CDR (Clinical Dementia Rating) scale score or MMSE (Mini-Mental State Examination) results documenting disease severity.

Step 4: Obtain a Neurologist or Geriatrician Medical Necessity Letter with Guideline Citations

Request a detailed letter from the treating neurologist or geriatrician confirming the Alzheimer's diagnosis, stage, and CDR score, stating the medical necessity of the specific services or medications being denied, referencing Alzheimer's Association Care Guidelines and AAN Practice Guidelines, addressing the insurer's specific "custodial care" or "not medically necessary" characterization, and documenting medical risks that make the supervised memory care environment clinically necessary.

Step 5: Cite Medicare Coverage Precedent for Disease-Modifying Drugs

For commercial payers denying lecanemab (Leqembi) or donanemab as "experimental," cite the FDA approval dates and CMS coverage decisions that established federal recognition that disease-modifying Alzheimer's treatment is medically necessary. A commercial insurer denying an FDA-approved medication that CMS covers is making a factually incorrect classification that can be directly challenged.

Step 6: File the Internal Appeal and Request External Independent Review: Complete Guide" class="auto-link">External Review if Denied

Submit your complete appeal package within the deadline (typically 180 days for commercial plans). For urgent care situations — where an Alzheimer's patient is at documented safety risk — request expedited review. If the internal appeal is denied, request external review by an IRO. External review is free under the ACA and the decision is binding on the insurer.

What to Include in Your Alzheimer's Care Appeal

• Written denial letter with specific reason code and policy provision cited, plus neurologist or geriatrician's formal diagnosis letter with ICD-10 code
• Neuropsychological assessment results (MMSE, MoCA, or full neuropsychological battery) and CDR or FAST score documenting disease stage
• ADL assessment results documenting functional impairment for LTC benefit triggers, and memory care facility assessment and care plan if applicable
• Documentation of safety risks such as wandering incidents, fall history, and medication management failures
• Clinical guideline citations from Alzheimer's Association and AAN, plus FDA approval documentation for any medication being denied as experimental
