About 0FMC0ZZ

0FMC0ZZ is the ICD-10-PCS code for a reattachment procedure on the ampulla of vater using an open approach. In ICD-10-PCS, reattachment means putting back in or on all or a portion of a separated body part to its normal location or other suitable location.

In plain terms, this corresponds to other operations on sphincter of Oddi, the ICD-9-CM procedure title it maps to (51.89).

For a different body part, codes include 0FM00ZZ (liver), 0FM10ZZ (liver, right lobe), 0FM20ZZ (liver, left lobe), 0FM40ZZ (gallbladder), 0FM50ZZ (right hepatic duct), 0FM60ZZ (left hepatic duct) and 6 more.

The same procedure with a different approach is coded 0FMC4ZZ (percutaneous endoscopic).

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 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Biliary Tract Procedures Except Only Cholecystectomy with or without C.D.E.”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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