Summary
Effective July 1, 2023, Indiana Medicaid (IHCP) replaced the daily H0020 billing code for Opioid Treatment Program services with new weekly reimbursement bundles using G-codes G2067-G2080. OTP providers must transition from daily to weekly billing cycles with specific codes for different medication types and services.
Action Required
By July 1, 2023: OTP providers (provider type 11, specialty 835) must stop using H0020 for daily billing and implement weekly bundle billing using new G-codes G2067-G2080. Update billing system with new fee schedules ranging from $31.19 to $5,604.87 per code. Train billing staff on weekly vs daily cycle changes and ensure proper code selection based on medication type (methadone, buprenorphine variants, naltrexone). Update encounter forms and documentation to support weekly bundled services including counseling, therapy, and toxicology testing.
