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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group XHR1 includes procedures performed to replace skin in the chest. These ICD-10-PCS codes are used for inpatient documentation when a replacement of chest skin with biological or synthetic material is performed. Accurate coding within the ICD-10-PCS XHR1 group is essential for proper inpatient reimbursement, as it captures the replacement procedure performed and supports clinical documentation accuracy.

Chest Replacement Procedure Overview

Procedures in this ICD-10-PCS code group involve replacement of skin on the chest and target the Skin, Subcutaneous Tissue, Fascia and Breast body system. These operations place biological material that physically takes the place and/or function of all or a portion of the chest skin. Accurate coding of the replacement procedure and body part supports correct inpatient documentation and is important for appropriate reimbursement and case mix assignment.

Typical Clinical Scenarios

An adult patient with a large full-thickness chest wall burn involving most of the anterior chest skin after a house fire is admitted for staged surgical reconstruction because native skin is nonviable and standard grafting options are limited; the team plans placement of a biologic autologous engineered cell therapy to replace the chest skin to restore coverage and promote healing. Typical codes: XHR1XGA
An older patient with extensive chest skin loss following excision of an aggressive chest wall soft-tissue malignancy and prior radiation resulting in poor local tissue quality is admitted for definitive reconstruction; the surgical plan uses a genetically engineered autologous cell therapy applied externally to replace the resected chest skin where conventional flap or graft options are contraindicated. Typical codes: XHR1XGA
A hospitalized patient who previously underwent skin-sparing mastectomy and developed recurrent, nonhealing chest skin breakdown with exposed underlying structures despite conservative care is taken back to the operating room for replacement of the failing chest skin with a novel autologous, genetically engineered cell therapy to achieve durable coverage. Typical codes: XHR1XGA
