Surgical repair of the liver via marsupialization and/or decompression of one or more cysts or abscesses. This is a surgical procedure payable to the surgeon (suffix A). Assistant (suffix B) and Anaesthesia (suffix C) services are also eligible for payment and are calculated using a time-based unit system. An add-on fee, E715, is payable when more than three cysts or abscesses are addressed.

When to Use

Use S273 for the surgical marsupialization of a symptomatic liver cyst where internal drainage is required to prevent recurrence.
Use S273 for the decompression of a liver abscess that is not amenable to percutaneous drainage and requires an open or laparoscopic surgical approach.

Common Pitfalls

Do not bill S273 for simple percutaneous aspiration of a liver cyst, as this is typically covered under diagnostic or image-guided procedure codes.
Avoid billing E715 unless the operative report explicitly documents the treatment of four or more distinct cysts or abscesses; billing for three or fewer will result in rejection.
Ensure the procedure is not bundled into a more comprehensive liver resection code, as S273 is intended for localized marsupialization or decompression only.

Billing Tips

If treating more than three cysts, ensure E715 is submitted on the same claim as S273 to trigger the flat fee add-on.
Always document the exact number of cysts or abscesses addressed in the operative report to support the use of E715 in the event of a post-payment audit.
