Why home health care denials happen so often
Home health care covers intermittent skilled nursing, physical therapy, occupational therapy, speech-language pathology, medical social services, and home health aide services delivered in a beneficiary's home. The eligibility rules are tight under Medicare and most commercial plans: the patient must be substantially homebound, must require skilled (not custodial) care, must be under a physician's plan of care, and the services must be reasonable and necessary for the treatment of the condition. Denials cluster around three pressure points - homebound eligibility (the patient is judged 'too well' to qualify), characterization of the care as custodial rather than skilled, and the move from intermittent to continuous care that triggers the denial of additional aide hours. Medicare Advantage home health denials have drawn particular scrutiny since the Senate Permanent Subcommittee on Investigations issued its October 2024 report documenting elevated post-acute denial rates among the largest MA insurers, including a high rate of denials reversed on appeal.
Why Home Health gets denied
Patient determined not 'homebound' under Medicare's two-part test
Care characterized as custodial (assistance with ADLs only) rather than skilled
OASIS data submitted by the home health agency contradicts the plan of care
Face-to-face encounter with certifying physician not within 90 days before or 30 days after start of care
Lack of documented skilled need at recertification (every 60 days)
Home health aide hours exceeded what the plan considers 'intermittent'
Concurrent or duplicate services with hospice (Medicare cannot pay for both for the same condition)
Coverage transitioned from Medicare home health to long-term services and supports without proper notice
Federal and state protections for Home Health
Medicare home health coverage is governed by 42 CFR Part 409 Subpart E and the CMS Medicare Benefit Policy Manual (Pub. 100-02), Chapter 7. The 'homebound' definition has two parts: (1) the patient must require the assistance of another person or supportive devices to leave home OR leaving home is medically contraindicated, and (2) there must exist a normal inability to leave home such that leaving requires considerable and taxing effort. Absences for medical treatment, religious services, family events, and adult day care do not break homebound status. The Jimmo v. Sebelius settlement applies to home health skilled care - lack of improvement is not a permissible basis for denial when skilled care is needed for maintenance or to prevent decline. Medicare Advantage home health appeals follow the Medicare Advantage process culminating in Independent Review Entity review. ACA-regulated commercial plans must provide internal appeal and external review under 45 CFR section 147.136.
Evidence checklist for your appeal
- Physician's certification of homebound status with detailed explanation of why leaving home requires considerable and taxing effort
- Face-to-face encounter note dated within 90 days before or 30 days after start of care, conducted by the certifying physician (or allowed non-physician practitioner)
- Plan of care (CMS Form 485) signed by the certifying physician
- OASIS assessment (start, recert, transfer, discharge) consistent with the appeal narrative
- Daily nursing or therapy notes documenting skilled interventions, not solely ADL assistance
- If Jimmo applies: explicit citation of the Jimmo v. Sebelius settlement and a reframe of the goal as maintenance or prevention of decline
- Quote of CMS Medicare Benefit Policy Manual Chapter 7 sections relevant to your facts
- For aide hour denials: documentation that aide care is intermittent (not continuous) and required to maintain a covered skilled service

Insurer-specific patterns and tactics
UnitedHealthcare's naviHealth (now Home & Community) unit has been a focus of investigative reporting and the October 2024 Senate PSI report for high post-acute denial rates and short authorized lengths of stay. Humana and CVS/Aetna similarly contract with post-acute management vendors that apply algorithmic stay-length predictions. The PSI report documented MA plans denying post-acute care including home health and SNF at higher rates than traditional Medicare and that more than 80% of those denials were overturned on appeal. Cite the report directly in MA appeals. For traditional Medicare home health denials by the MAC (CGS, Palmetto, NGS, Noridian), the appeal goes through the standard five-level Medicare process beginning with redetermination.
