How to appeal an Aetna home healthcare — home nursing, home infusion, home pt/ot/slp, home aide, hospital-at-home denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

Aetna-specific note: Owned by CVS Health since 2018. CVS Caremark is the PBM. Aetna ASA administers self-funded ERISA plans. Meritain Health is Aetna's TPA brand.

What Aetna's policy requires for home healthcare — home nursing, home infusion, home pt/ot/slp, home aide, hospital-at-home

Cited policy: Aetna Clinical Policy Bulletin (Home Health Care) + Aetna Clinical Policy Bulletin (IVIG and SCIG) + drug-class home infusion policies

Home IVIG: documented diagnosis indication (CIDP, PI, MMN, ITP, etc. per CPB 0206); stable patient; trained patient/caregiver; INS-compliant administration; prior tolerance.

How Aetna denies home healthcare — home nursing, home infusion, home pt/ot/slp, home aide, hospital-at-home — and how to counter it

Where Aetna pushes back: 1) 'Use infusion center'; 2) Diagnosis indication disputed; 3) Prior tolerance not documented; 4) IV access concerns.

Counter-arguments that hold up: Document diagnosis with ICD-10 + diagnostic criteria (CIDP: EFNS/PNS criteria; PI: IUIS criteria; MMN: AAN criteria). Document barriers to center (transportation, work/school, immune-compromise, mobility, distance). Document prior tolerance (X cycles in center without reactions). Cite INS Standards of Practice for home IV administration. Cite IDSA OPAT for parallel rationale on home administration safety. Cost-effectiveness vs center.
