Use modifiers with physical therapy (PT) and occupational therapy (OT) authorizations
Minnesota Medicaid (MHCP)·Identified May 5, 2026
Minnesota Health Care Programs (MHCP) now requires specific modifiers on all physical therapy (PT) and occupational therapy (OT) authorizations and claims: modifier GO for OT services, modifier GP for PT services (regardless of whether provided by therapist or assistant), and modifier U7 when an assistant provides services without the supervising therapist on site. Authorization requests and corresponding claims must match exactly, including modifiers, or claims will be denied. For members with third-party liability or Medicare, modifiers KX, CO, and CQ must also be used when appropriate.
