About 0D9QXZX

0D9QXZX is the ICD-10-PCS code for a drainage procedure on the anus using an external 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).

The same procedure with a different approach is coded 0D9Q0ZX (open), 0D9Q3ZX (percutaneous), 0D9Q4ZX (percutaneous endoscopic), 0D9Q7ZX (via natural or artificial opening) and 0D9Q8ZX (via natural or artificial opening 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.
