Last updated: 11/28/2025

What is a HCPCS Code?

HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.

Detailed Description

This code is used by healthcare providers to document and track your current ability to walk and move around during physical or occupational therapy. It represents an evaluation of your mobility functional limitations at the beginning of your therapy episode and at regular reporting intervals throughout your treatment. This assessment helps therapists monitor your progress and adjust your treatment plan as needed.

Additional Information

This is a reporting code used for documentation purposes during therapy episodes. It does not represent a specific treatment or procedure, but rather tracks your functional mobility status over time.
