About 0DBM4ZX

0DBM4ZX is the ICD-10-PCS code for a excision procedure on the descending colon using a percutaneous endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to closed [endoscopic] biopsy of large intestine, the ICD-9-CM procedure title it maps to (45.25).

For a different body part, codes include 0DB14ZX (esophagus, upper), 0DB24ZX (esophagus, middle), 0DB34ZX (esophagus, lower), 0DB44ZX (esophagogastric junction), 0DB54ZX (esophagus), 0DB64ZX (stomach) and 20 more.

The same procedure with a different approach is coded 0DBM0ZX (open), 0DBM3ZX (percutaneous), 0DBM7ZX (via natural or artificial opening) and 0DBM8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 361 (Other Circulatory System O.R. Procedures with MCC), DRG 362 (Other Circulatory System O.R. Procedures without MCC), 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) and DRG 820 (Lymphoma and Leukemia with Major O.R. Procedures with MCC), under the surgical categories “Other Circulatory System O.R. Procedures”, “Major Small and Large Bowel Procedures”, “Lymphoma and Leukemia with Major O.R. Procedures” and 3 more.

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