T-codes — State Medicaid Codes
114 codes — T-codes: National T-codes established for State Medicaid Agencies
Codes established for state Medicaid agencies to track services unique to their programs.
T-codes (T1000-T9999) are maintained for state Medicaid programs and are never used in Medicare billing. They cover services Medicaid programs need to track for waiver, home- and community-based services (HCBS), and other state-specific programs — personal care services, transportation, habilitation services, and many others.
T-code coverage and pricing are entirely state-specific. Always consult the payer's published fee schedule and authorization requirements.
