About 0D9Q40Z

0D9Q40Z is the ICD-10-PCS code for a drainage procedure on the anus using a percutaneous endoscopic approach with drainage device. In ICD-10-PCS, drainage means taking or letting out fluids and/or gases from a body part.

In plain terms, this corresponds to other incision of perianal tissue, the ICD-9-CM procedure title it maps to (49.02).

For a different body part, codes include 0D9140Z (esophagus, upper), 0D9240Z (esophagus, middle), 0D9340Z (esophagus, lower), 0D9440Z (esophagogastric junction), 0D9540Z (esophagus), 0D9640Z (stomach) and 20 more.

The same procedure with a different approach is coded 0D9Q00Z (open), 0D9Q30Z (percutaneous), 0D9Q70Z (via natural or artificial opening), 0D9Q80Z (via natural or artificial opening endoscopic) and 0D9QX0Z (external).

With a different device, use 0D9Q4ZZ (no device).

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 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Anal and Stomal Procedures” and “Other Skin, Subcutaneous Tissue and Breast Procedures”.

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