Wiki Medicaid Modifiers GO vs GP?

[Penelope]

I am new to billing for an Audiology practice. I have a patient who had an Audiogram 92557. DX code 388.12 Our billing company says that Medicaid is requiring a modifier of either GO or GP. I do not know what either modifier means. Help!

Hi! The short answer is:

GO-service delivered by an Occupational Therapist

GP-service delivered by a Physical Therapist

There is a whole list in Appendix A in the back of the CPT. I hope this helps!
