What 49424 covers

A clinician injects contrast through an existing catheter or other access into an abscess cavity, cyst, or sinus tract, then obtains and interprets imaging to assess its shape, extent, or communication with nearby structures. This study is commonly performed by an interventional radiologist or another physician managing a percutaneous drain, in a hospital or outpatient setting. A sinogram through an established tract is a typical use; this code describes assessment, not placement of a new drainage catheter.

Report the study when documentation identifies the target cavity or tract, the reason for assessment, the contrast injection and imaging performed, and the findings. The service includes radiological supervision and interpretation. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
