About 0D9R0ZX

0D9R0ZX is the ICD-10-PCS code for a drainage procedure on the anal sphincter using an open approach (qualifier: diagnostic). In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to biopsy of perianal tissue and biopsy of anus, the ICD-9-CM procedure titles it maps to (49.22 and 49.23).

For a different body part, codes include 0D910ZX (esophagus, upper), 0D920ZX (esophagus, middle), 0D930ZX (esophagus, lower), 0D940ZX (esophagogastric junction), 0D950ZX (esophagus), 0D960ZX (stomach) and 20 more.

The same procedure with a different approach is coded 0D9R3ZX (percutaneous) and 0D9R4ZX (percutaneous endoscopic).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

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