Section 10.6: https://www.cms.gov/Regulations-and-Guidance/Guidance/Manuals/downloads/bp102c15.PDF.
Modifiers GN, GO, and GP refer only to services provided under plans of care for physical therapy, occupational therapy, and speech-language pathology services. They should never be used with codes not on the list of applicable therapy services. For example, respiratory therapy services or nutrition therapy services shall not be represented by therapy codes that require GN, GO, and GP modifiers.
Note: Due to CY 2019 Physician Fee Schedule (PFS) rulemaking, effective for dates of service on or after January 1, 2019, Medicare no longer requires the functional reporting of non-payable HCPCS G-codes and severity modifiers − adopted to implement section 3005(g) of MCTRJCA − on claims for therapy services. For details about these payment policies, see MLN Matters article MM11120 at https://www.cms. gov/Outreach-and-Education/Medicare-Learning-Network-MLN/MLNMattersArticles/Downloads/MM11120.pdf.
UPDATE: 2020 Annual Update to the Therapy Code List
