ICD-10-PCS Code For Back: Procedure Code Group Overview

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group XHR3 includes procedures performed to replace skin in the back. These ICD-10-PCS codes are used for inpatient documentation when a portion or all of back skin is replaced with biological or synthetic material. Accurate coding within the ICD-10-PCS XHR3 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Back Replacement Procedure Overview

Procedures in this ICD-10-PCS code group involve replacement of skin on the back and target the skin, subcutaneous tissue, fascia, and breast body system. These replacement procedures place biological or synthetic material that takes the place and/or function of all or part of the back skin. Accurate coding of the specific replacement procedure and approach is important for inpatient reimbursement because it captures the clinical service performed and supports appropriate case mix assignment and payment.

When to Use

Use a code from this group when the operative intent is replacement of part or all of the back skin rather than repair or grafting alone. Codes in this group are reported for inpatient encounters when a replacement material is placed on the back by an external approach.

Typical Clinical Scenarios

A middle-aged patient with a large full-thickness thermal burn involving most of the posterior trunk arrives after initial resuscitation; the burn has destroyed native skin over an extensive area and temporary measures are failing to protect underlying structures, so inpatient replacement of back skin with a biologic autologous engineered cell therapy is planned to restore coverage and promote healing. Typical codes: XHR3XGA
An elderly patient with chronic nonhealing radiation-induced skin loss of the upper and mid back following prior cancer therapy is admitted for definitive wound coverage because local flap options are exhausted and the wound is at high risk for infection and further breakdown; inpatient replacement using a genetically engineered autologous cell product is selected to replace the damaged skin. Typical codes: XHR3XGA
A patient with a large excision of a recurrent malignant cutaneous tumor on the back undergoes inpatient reconstruction when standard grafts have failed and margins require wide replacement of skin over the defect; the team elects to place an autologous genetically engineered cell therapy product externally to replace the resected skin surface and support healing. Typical codes: XHR3XGA
