About 0FBC0ZX

0FBC0ZX is the ICD-10-PCS code for a excision procedure on the ampulla of vater using an open 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 open biopsy of gallbladder or bile ducts, the ICD-9-CM procedure title it maps to (51.13).

For a different body part, codes include 0FB00ZX (liver), 0FB10ZX (liver, right lobe), 0FB20ZX (liver, left lobe), 0FB40ZX (gallbladder), 0FB50ZX (right hepatic duct), 0FB60ZX (left hepatic duct) and 6 more.

The same procedure with a different approach is coded 0FBC3ZX (percutaneous), 0FBC4ZX (percutaneous endoscopic), 0FBC7ZX (via natural or artificial opening) and 0FBC8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC), DRG 420 (Hepatobiliary Diagnostic Procedures with MCC), DRG 421 (Hepatobiliary Diagnostic Procedures with CC) and DRG 422 (Hepatobiliary Diagnostic Procedures without CC/MCC), under the surgical categories “Other Digestive System O.R. Procedures” and “Hepatobiliary Diagnostic Procedures”.

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