About 0DMM4ZZ

0DMM4ZZ is the ICD-10-PCS code for a reattachment procedure on the descending colon using a percutaneous endoscopic 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 repair of intestine, the ICD-9-CM procedure title it maps to (46.79).

For a different body part, codes include 0DM54ZZ (esophagus), 0DM64ZZ (stomach), 0DM84ZZ (small intestine), 0DM94ZZ (duodenum), 0DMA4ZZ (jejunum), 0DMB4ZZ (ileum) and 8 more.

The same procedure with a different approach is coded 0DMM0ZZ (open).

It is an operating-room procedure in the MS-DRG logic for DRG 329 (Major Small and Large Bowel Procedures with MCC), DRG 330 (Major Small and Large Bowel Procedures with CC), DRG 331 (Major Small and Large Bowel Procedures 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 “Major Small and Large Bowel Procedures” and “Other O.R. Procedures for Injuries”.

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