Summary
Humana Medicare Advantage has revised its Home Mechanical Ventilators (HMV) coverage policy effective 09/01/2026, establishing specific medical necessity criteria for three condition categories: neuromuscular disorders, obesity hypoventilation syndrome (OHS), and restrictive chest wall disorders. The policy clarifies that HMVs (E0466) require documented respiratory failure meeting defined thresholds and, for OHS and chest wall disorders, limits initial coverage to 180 days when used in volume-targeted mode. Billing teams must update prior authorization workflows and documentation requirements across all four DME MAC jurisdictions.

What to do
by Aug 31, 2026 · 8 steps
01Billing team and prior authorization staff must implement updated medical necessity criteria for HMV claims (E0466) across all Humana Medicare Advantage jurisdictions.
02Update authorization software to require documentation of one or more respiratory failure indicators for neuromuscular disorders (PaCO2 ≥45 mmHg, FVC <50% predicted, MIP <-60 cm H2O, oxygen saturation ≤88% for ≥5 consecutive minutes, or SNIP <40 cm H2O).
03For OHS cases, require BMI >30, documented CPAP failure after 3 months, PaCO2 ≥45 mmHg, and sleep study documentation (AHI ≥5 or oxygen saturation ≤88% for ≥5 consecutive minutes); limit initial approval to 180 days and require volume-targeted mode notation.
04For chest wall disorders (kyphoscoliosis, asphyxiating thoracic dystrophy, ankylosing spondylitis, etc.), require respiratory failure documentation and limit to 180-day initial period with volume-targeted mode.
05Create prior authorization checklists for providers listing all required clinical documentation to avoid claim denials.
06Audit and train billing staff on new criteria.
07Claims submitted without meeting these specific medical necessity criteria will be denied.
08Applies to all four DME MAC jurisdictions: DME A (Northeast), DME B (Midwest), DME C (South), and DME D (West).
