Answer: The answer depends on whether the FP treated both the upper and lower extremities. The osteopathic manipulation treatment (OMT) codes (98925-98929) refer to 11 body regions:
viscera. Whether the FP performs multiple manipulations in a region doesn't matter. So you shouldn't count left and right manipulations in the same area, such as the cervical region.
Bilateral also doesn't apply to the extremities. Therefore, instead of focusing on the extremity's side, you should look at whether the FP treated the upper or lower extremities.
In your case, you should count one OMT for each of these regions:
abdomen. You may also add OMT of the:
upper extremities. Bottom line: You should report either OMT of three or four body regions. This amount doesn't affect the code you should use. Code 98296 (Osteopathic manipulation treatment [OMT]; three to four body regions involved) refers to OMT involving three-four body regions.
