OT Therapy Coding

Taylor Posted Thu 12th of September, 2019 11:18:13 AM
We have come across an issue lately where we are fitting patients with a JAS Brace or a splint (97763) and then they are also doing therapy for the patient (97110 and 97140) to fill in the whole 45-minute session. We got a denial from Humana for 97110 and 97140 as procedure modifier is invalid, but when I enter these codes into the check edits, it is requesting modifiers on both these codes. I did 59 on both 97110 and 97140 but it is still getting denied. What more can I do?

As per CMS guidelines, “CPT code 97763 is designated as “always therapy” and must always be reported with the appropriate therapy modifier, GN, GO or GP, to indicate whether it’s under a Speech-language pathology (SLP), Occupational Therapy (OT) or Physical Therapy (PT) plan of care, respectively.”

If 97763 procedure is performed by an occupational therapist, then also add modifier GO with CPT 97763.

We have done that as well as adding a 59 and GO to the other codes but insurances are still denying as inclusive.

As per CMS guidelines, CPT codes 97110, 97112, 97113, 97116, 97124, 97140, 97530, 97533, 97535,97537, 97542, 97760, 97761, 97763, and G0515 describe different types of therapeutic interventions. The expected goals documented in the treatment plan, affected by the use of each of these procedures, will help define whether these procedures are reasonable and necessary. Therefore, since any one or a combination of these procedures may be used in a treatment plan, documentation must support the use of each procedure as it relates to a specific therapeutic goal.

For billing 97763, 97110, and 97140 documentation must clearly support the medical necessity.


Supportive documentation recommendations for billing 97763, 97110 and 97140 are as follows:

  • If used for pain include pain rating, location of pain, effect of pain on function Specific exercises performed, purpose of exercises as related to function, instructions given, and/or assistance needed to perform exercises to demonstrate that the skills of a therapist were required

  • Area(s) being treated
  • Soft tissue or joint mobilization technique used
  • Objective and subjective measurements of areas treated (may include ROM, capsular end-feel, pain descriptions and ratings,) and effect on function
  • For MLD/CDP, supportive documentation should include:

    • pain/discomfort descriptions and ratings;
