About 0DBB0ZZ

0DBB0ZZ is the ICD-10-PCS code for a excision procedure on the ileum using an open 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 local excision of lesion or tissue of small intestine, except duodenum and other partial resection of small intestine, the ICD-9-CM procedure titles it maps to (45.33 and 45.62).

For a different body part, codes include 0DB10ZZ (esophagus, upper), 0DB20ZZ (esophagus, middle), 0DB30ZZ (esophagus, lower), 0DB40ZZ (esophagogastric junction), 0DB50ZZ (esophagus), 0DB60ZZ (stomach) and 20 more.

The same procedure with a different approach is coded 0DBB3ZZ (percutaneous), 0DBB4ZZ (percutaneous endoscopic), 0DBB7ZZ (via natural or artificial opening) and 0DBB8ZZ (via natural or artificial opening endoscopic).

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) and DRG 331 (Major Small and Large Bowel Procedures without CC/MCC), under the surgical category “Major Small and Large Bowel Procedures”.

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