About 0H9EX0Z

0H9EX0Z is the ICD-10-PCS code for a drainage procedure on the skin, left lower arm using an external 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 with drainage of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.04).

For a different body part, codes include 0H90X0Z (skin, scalp), 0H91X0Z (skin, face), 0H92X0Z (skin, right ear), 0H93X0Z (skin, left ear), 0H94X0Z (skin, neck), 0H95X0Z (skin, chest) and 20 more.

With a different device, use 0H9EXZZ (no device).

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.
