Marty went to the doctor's office with a sore throat and an upset stomach. The doctor performed an exam and evaluation of Marty. In the course of the evaluation, Marty mentioned he was having some back pain. The doctor also evaluated this issue and performed an osteopathic manipulation on one body region. The doctor reported a 99213 with a(n) modifier and a 98925 for the OMT.

- 25 modifier

Explanation:

The modifier 25 was used in this case because the doctor reported either a surgical procedure, X-rays, labs and supply codes that and this shows that it was documented as an E and M service that was separately identified but performed on the same day as though it is another procedure. Also, in a case where a patient visit the healthcare and it was not anticipated that a procedure might be carried out on her, but eventually it was, the E&M can also be assigned with the 25 modifier.
