Outpatient FAQ: Therapy Threshold Amounts for 2024

Published on 

Wednesday, January 10, 2024


Are there any updates for rehabilitative therapy services’ threshold amounts for the coming year?



Yes. Change Request (CR) 13371 issued September 14, 2023 and re-communicated November 6, 2023 updates the annual per-beneficiary incurred expenses amounts now called the KX modifier thresholds and related policy for CY 2024. These thresholds were previously known as “therapy caps.”


CY 2024 KX Modifier Threshold Amounts

  1. $2,330 for Physical Therapy (PT) and Speech-Language Pathology (SLP) services combined, and
  2. $2,330 for Occupational Therapy (OT) services.


Providers can track a patient’s year-to-date therapy amounts on Medicare eligibility screens. The KX modifier must be appended to therapy services’ line-items on the claim for medically necessary therapy services above the threshold amounts. The medical necessity of services beyond the threshold amount must be justified by appropriate documentation in the medical record. Services provided beyond the threshold that are not billed with the KX modifier will be denied with Claim Adjustment Reason Code 119 - Benefit maximum for this time period or occurrence has been reached.


There is also a therapy threshold related to the targeted medical review process, now known as the Medical Record (MR) threshold amount. This threshold remains at $3,000 for PT and SLP combined and a separate $3,000 for OT until CY 2028.
