About 0F990ZZ

0F990ZZ is the ICD-10-PCS code for a drainage procedure on the common bile duct 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 exploration of common duct, the ICD-9-CM procedure title it maps to (51.51).

For a different body part, codes include 0F900ZZ (liver), 0F910ZZ (liver, right lobe), 0F920ZZ (liver, left lobe), 0F940ZZ (gallbladder), 0F950ZZ (right hepatic duct), 0F960ZZ (left hepatic duct) and 6 more.

The same procedure with a different approach is coded 0F993ZZ (percutaneous), 0F994ZZ (percutaneous endoscopic), 0F997ZZ (via natural or artificial opening) and 0F998ZZ (via natural or artificial opening endoscopic).

With a different device, use 0F9900Z (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), DRG 410 (Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E. without CC/MCC), DRG 411 (Cholecystectomy with C.D.E. with MCC), DRG 412 (Cholecystectomy with C.D.E. with CC) and DRG 413 (Cholecystectomy with C.D.E. without CC/MCC), under the surgical categories “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.” and “Cholecystectomy”.

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