About 0HNEXZZ

0HNEXZZ is the ICD-10-PCS code for a release procedure on the skin, left lower arm using an external approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to relaxation of scar or web contracture of skin, the ICD-9-CM procedure title it maps to (86.84).

For a different body part, codes include 0HN0XZZ (skin, scalp), 0HN1XZZ (skin, face), 0HN2XZZ (skin, right ear), 0HN3XZZ (skin, left ear), 0HN4XZZ (skin, neck), 0HN5XZZ (skin, chest) and 20 more.

It is an operating-room procedure in the MS-DRG logic for DRG 579 (Other Skin, Subcutaneous Tissue and Breast Procedures with MCC), DRG 580 (Other Skin, Subcutaneous Tissue and Breast Procedures with CC), DRG 581 (Other Skin, Subcutaneous Tissue and Breast Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Skin, Subcutaneous Tissue and Breast Procedures”, “Other O.R. Procedures for Injuries” and “Other O.R. Procedures for Multiple Significant Trauma”.

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