About 0HR3XK4

0HR3XK4 is the ICD-10-PCS code for a replacement procedure on the skin, left ear using an external approach with nonautologous tissue substitute (qualifier: partial thickness). In ICD-10-PCS, replacement means putting in or on biological or synthetic material that physically takes the place and/or function of all or a portion of a body part.

In plain terms, this corresponds to reconstruction of external auditory canal, the ICD-9-CM procedure title it maps to (18.6).

For a different body part, codes include 0HR0XK4 (skin, scalp), 0HR1XK4 (skin, face), 0HR2XK4 (skin, right ear), 0HR4XK4 (skin, neck), 0HR5XK4 (skin, chest), 0HR6XK4 (skin, back) and 16 more.

With a different device, use 0HR3X74 (autologous tissue substitute) and 0HR3XJ4 (synthetic substitute).

It is an operating-room procedure in the MS-DRG logic for DRG 143 (Other Ear, Nose, Mouth and Throat O.R. Procedures with MCC), DRG 144 (Other Ear, Nose, Mouth and Throat O.R. Procedures with CC), DRG 145 (Other Ear, Nose, Mouth and Throat O.R. Procedures without CC/MCC), DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC) and DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), under the surgical categories “Other Ear, Nose, Mouth and Throat O.R. Procedures”, “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
