I have a PT billing company and also do coding for physical therapy, orthopedic, podiatry and other specialties so I get a lot of questions about coding and reimbursement. I thought that I'd share some of the most interesting ones on this blog. For example, someone asked us recently about coding for PT and OT evaluations that also included some modalities and/or procedures. The issue was about how to clarify that they were not provided in the same time period when submitting to payors. We recommended using a modifier (depending on the insurance companies) to indicate both were done and to document that the evaluation was done followed by the modality (or procedure). How would you handle that?
