Answer: You should report CPT 00532 (Anesthesia for access to central venous circulation) and append modifier -QZ (CRNA service: without medical direction by a physician) if no anesthesiologist supervised the case. Then switch the order of your diagnoses.
Some states (including Texas) publish a list of noncovered V codes, which might explain your denials.
Report 730.05 (Osteomyelitis, periostitis, and other infections involving bone; acute osteomyelitis; pelvic region and thigh) as the primary diagnosis and V49.89 (Other specified conditions influencing health status) as your secondary diagnosis code.
