CY 2023 Threshold Amounts for Therapy Services Now Updated

The Centers for Medicare and Medicaid Services (CMS) has updated the calendar year (CY) 2023 per beneficiary threshold amounts for therapy services. These threshold amounts, also known as therapy caps, are reflected on claims with the KX modifier to confirm that services are medically necessary as justified by appropriate documentation in the medical record. There is one amount for Physical Therapy (PT) and Speech-Language Pathology (SLP) services combined and a separate amount for Occupational Therapy (OT) services. Claims from providers for therapy services above the threshold amounts without the KX modifier are denied.

For CY 2023, the KX modifier threshold amounts are: (a) $2,230 for PT and SLP services combined, and (b) $2,230 for OT services.
