Therapy Modifiers And HCPCS Codes G0237, G0238, & G0239
No, HCPCS codes G0237, G0238, and G0239 should be billed without therapy modifiers. These HCPCS codes describe services for the improvement of respiratory function and may represent either “incident to” services or respiratory therapy services that may be appropriately billed in the CORF setting. When the services described by these G-codes are provided by physical therapists (PTs) or occupational therapists (OTs) treating respiratory conditions, they are considered therapy services and must meet the other conditions for physical and occupational therapy. The PT or OT would use the appropriate HCPCS/CPT code(s) in the 97000 – 97799 series and the corresponding therapy modifier, GP or GO, must be used.
Another example of codes that are not on the list of therapy services and should not be billed with a therapy modifier includes the following HCPCS codes: 95860, 95861, 95863, 95864, 95867, 95869, 95870, 95900, 95903, 95904, and 95934. These services represent diagnostic services – not therapy services; they must be appropriately billed and shall not include therapy modifiers.
