About 0H93XZZ

0H93XZZ is the ICD-10-PCS code for a drainage procedure on the skin, left ear using an external approach. 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 of external ear, the ICD-9-CM procedure title it maps to (18.09).

For a different body part, codes include 0H90XZZ (skin, scalp), 0H91XZZ (skin, face), 0H92XZZ (skin, right ear), 0H94XZZ (skin, neck), 0H95XZZ (skin, chest), 0H96XZZ (skin, back) and 20 more.

With a different device, use 0H93X0Z (drainage 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.
