About 0D9L7ZX

0D9L7ZX is the ICD-10-PCS code for a drainage procedure on the transverse colon using a via natural or artificial opening 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 closed [endoscopic] biopsy of large intestine, the ICD-9-CM procedure title it maps to (45.25).

For a different body part, codes include 0D917ZX (esophagus, upper), 0D927ZX (esophagus, middle), 0D937ZX (esophagus, lower), 0D947ZX (esophagogastric junction), 0D957ZX (esophagus), 0D967ZX (stomach) and 16 more.

The same procedure with a different approach is coded 0D9L0ZX (open), 0D9L3ZX (percutaneous), 0D9L4ZX (percutaneous endoscopic) and 0D9L8ZX (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.
