About 0H9AXZX

0H9AXZX is the ICD-10-PCS code for a drainage procedure on the skin, inguinal 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 closed biopsy of skin and subcutaneous tissue, the ICD-9-CM procedure title it maps to (86.11).

For a different body part, codes include 0H90XZX (skin, scalp), 0H91XZX (skin, face), 0H92XZX (skin, right ear), 0H93XZX (skin, left ear), 0H94XZX (skin, neck), 0H95XZX (skin, chest) and 20 more.

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.
