About 0F940ZZ

0F940ZZ is the ICD-10-PCS code for a drainage procedure on the gallbladder using an open approach. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other cholecystostomy, the ICD-9-CM procedure title it maps to (51.03).

For a different body part, codes include 0F900ZZ (liver), 0F910ZZ (liver, right lobe), 0F920ZZ (liver, left lobe), 0F950ZZ (right hepatic duct), 0F960ZZ (left hepatic duct), 0F970ZZ (hepatic duct, common) and 6 more.

The same procedure with a different approach is coded 0F943ZZ (percutaneous), 0F944ZZ (percutaneous endoscopic) and 0F948ZZ (via natural or artificial opening endoscopic).

With a different device, use 0F9400Z (drainage device).

It is an operating-room procedure in the MS-DRG logic for DRG 408 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. with MCC), DRG 409 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. with CC) and DRG 410 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. without CC/MCC), under the surgical category “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”.

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