Summary
Humana Medicare Advantage has revised their substance use disorder inpatient services policy, establishing specific medical necessity criteria for detoxification and rehabilitation services. The policy clarifies when inpatient SUD treatment will be covered versus denied, requiring documentation of complex medical factors and failed outpatient attempts for rehab services.
Action Required
By August 1, 2025: Providers treating SUD patients must ensure documentation includes complex medical factors for detox admissions (delirium, confusion, trauma, unconsciousness) and evidence of failed outpatient treatment for rehab admissions. Update admission order templates to include provisional diagnosis of comorbid conditions and individualized treatment plans with psychiatric management and abstinence strategies. Billing team should flag SUD inpatient claims for additional documentation review to prevent denials.
