About 0DBB0ZX

0DBB0ZX is the ICD-10-PCS code for a excision procedure on the ileum using an open 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 open biopsy of small intestine, the ICD-9-CM procedure title it maps to (45.15).

For a different body part, codes include 0DB10ZX (esophagus, upper), 0DB20ZX (esophagus, middle), 0DB30ZX (esophagus, lower), 0DB40ZX (esophagogastric junction), 0DB50ZX (esophagus), 0DB60ZX (stomach) and 20 more.

The same procedure with a different approach is coded 0DBB3ZX (percutaneous), 0DBB4ZX (percutaneous endoscopic), 0DBB7ZX (via natural or artificial opening) and 0DBB8ZX (via natural or artificial opening endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 344 (Minor Small and Large Bowel Procedures with MCC), DRG 345 (Minor Small and Large Bowel Procedures with CC) and DRG 346 (Minor Small and Large Bowel Procedures without CC/MCC), under the surgical category “Minor Small and Large Bowel Procedures”.

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