Really need some help coding ortho office visits and exams. Payers (specifically BCBS) are bundling office visits with X-rays! A patient presents for a recent injury, followed by pain, and X-ray results indicate a sprain. The physician charges a 9921x and an X-ray. Should we append a -25 modifier? And which charge should list which dx? Also, any suggestions on possible issues using the 729.5 (pain) dx?
