About 0H93XZX

0H93XZX is the ICD-10-PCS code for a drainage procedure on the skin, left ear 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 external ear, the ICD-9-CM procedure title it maps to (18.12).

For a different body part, codes include 0H90XZX (skin, scalp), 0H91XZX (skin, face), 0H92XZX (skin, right ear), 0H94XZX (skin, neck), 0H95XZX (skin, chest), 0H96XZX (skin, back) 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.
