Recently the Centers for Medicare and Medicaid Services (CMS) revised an educational tool titled: Quick Reference Chart: Descriptors of G-codes and Modifiers for Therapy Functional Reporting.
The Middle Class Tax Relief and Jobs Creation Act (MCTRJCA) of 2012 amended the Social Security Act to require a claims-based data collection system for Medicare Part B outpatient therapy services, including physical therapy (PT), occupational therapy (OT), and speech-language pathology (SLP) services. The system collects data on beneficiary function during the course of therapy services to better understand beneficiary conditions, outcomes, and expenditures. Beneficiary function information is reported using 42 nonpayable functional G-codes and seven severity/complexity modifiers on Part B therapy claims for PT, OT, and SLP services. SNF billers and therapists are encouraged to review the revised reference chart.
