About 0DBM7ZZ

0DBM7ZZ is the ICD-10-PCS code for a excision procedure on the descending colon using a via natural or artificial opening approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to excision of lesion or tissue of large intestine and other and unspecified partial excision of large intestine, the ICD-9-CM procedure titles it maps to (45.41 and 45.79).

For a different body part, codes include 0DB17ZZ (esophagus, upper), 0DB27ZZ (esophagus, middle), 0DB37ZZ (esophagus, lower), 0DB47ZZ (esophagogastric junction), 0DB57ZZ (esophagus), 0DB67ZZ (stomach) and 16 more.

The same procedure with a different approach is coded 0DBM0ZZ (open), 0DBM3ZZ (percutaneous), 0DBM4ZZ (percutaneous endoscopic), 0DBM8ZZ (via natural or artificial opening endoscopic) and 0DBMFZZ (via natural or artificial opening with percutaneous endoscopic assistance).

It is an operating-room procedure in the MS-DRG logic for DRG 347 (Anal and Stomal Procedures with MCC), DRG 348 (Anal and Stomal Procedures with CC), DRG 349 (Anal and Stomal Procedures without CC/MCC), DRG 628 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with MCC or Insertion of Antibiotic-eluting Bone Void Filler), DRG 629 (Other Endocrine, Nutritional and Metabolic O.R. Procedures with CC) and DRG 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures without CC/MCC), under the surgical categories “Anal and Stomal Procedures” and “Other Endocrine, Nutritional and Metabolic O.R. Procedures”.

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