About 0FBC4ZX

0FBC4ZX is the ICD-10-PCS code for a excision procedure on the ampulla of vater using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to other closed [endoscopic] biopsy of biliary duct or sphincter of Oddi, the ICD-9-CM procedure title it maps to (51.14).

For a different body part, codes include 0FB04ZX (liver), 0FB14ZX (liver, right lobe), 0FB24ZX (liver, left lobe), 0FB44ZX (gallbladder), 0FB54ZX (right hepatic duct), 0FB64ZX (left hepatic duct) and 6 more.

The same procedure with a different approach is coded 0FBC0ZX (open), 0FBC3ZX (percutaneous), 0FBC7ZX (via natural or artificial opening) and 0FBC8ZX (via natural or artificial opening endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
