About 0D9Q3ZX

0D9Q3ZX is the ICD-10-PCS code for a drainage procedure on the anus using a percutaneous 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 0D913ZX (esophagus, upper), 0D923ZX (esophagus, middle), 0D933ZX (esophagus, lower), 0D943ZX (esophagogastric junction), 0D953ZX (esophagus), 0D963ZX (stomach) and 20 more.

The same procedure with a different approach is coded 0D9Q0ZX (open), 0D9Q4ZX (percutaneous endoscopic), 0D9Q7ZX (via natural or artificial opening), 0D9Q8ZX (via natural or artificial opening endoscopic) and 0D9QXZX (external).

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.
