About 0DBQ0ZX

0DBQ0ZX is the ICD-10-PCS code for a excision procedure on the anus 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 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 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 0DBQ3ZX (percutaneous), 0DBQ4ZX (percutaneous endoscopic), 0DBQ7ZX (via natural or artificial opening), 0DBQ8ZX (via natural or artificial opening endoscopic) and 0DBQXZX (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.
