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

The International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS) code group 6A80 includes procedures performed to apply ultraviolet light therapy to the skin using extracorporeal methods. These ICD-10-PCS codes are used for inpatient documentation when extracorporeal ultraviolet light treatment of skin-related conditions is performed, often involving processing of blood or skin components outside the body. Accurate coding within the ICD-10-PCS 6A80 group is essential for proper inpatient reimbursement, as it captures the procedure performed and determines appropriate case mix and payment.

Skin Ultraviolet Light Therapy Procedure Overview

The procedures in ICD-10 PCS 6A80 involve extracorporeal ultraviolet light therapy applied to the skin, targeting physiological systems through ultraviolet light delivered outside the body. These treatments typically process blood or skin components with ultraviolet light to treat dermatologic or systemic conditions affecting the skin. Accurate coding of these procedures is important for inpatient reimbursement because it captures the specific extracorporeal ultraviolet therapy performed and supports appropriate case mix classification and payment.

When to Use

Use a code from this group when an extracorporeal ultraviolet light therapy procedure is performed for a skin-related condition during an inpatient stay. These codes apply when blood or other skin-associated components are treated outside the body with ultraviolet light as part of the therapeutic intervention.

Typical Clinical Scenarios

An adult patient with severe, widespread cutaneous T-cell lymphoma is admitted for inpatient photopheresis as part of combination therapy. Peripheral blood is collected, treated extracorporeally with ultraviolet A light after photosensitizer exposure, and returned to the patient to reduce malignant T-cell burden and control skin manifestations. The procedure is performed during the admission because of disease severity and need for supervised systemic therapy. Typical codes: 6A801ZZ
An elderly patient presents to the hospital with rapidly progressive scleroderma-associated skin ulcers and systemic inflammatory features unresponsive to topical measures. The medical team initiates extracorporeal ultraviolet light treatment of blood components during the inpatient stay to modulate immune activity and promote wound healing while monitoring hemodynamic status. The intervention is carried out as a scheduled inpatient procedure given the patient’s frailty and need for close observation. Typical codes: 6A801ZZ
A patient previously treated with a single-session extracorporeal ultraviolet therapy is readmitted for a repeat treatment course due to persistent or recurrent extensive cutaneous disease after initial partial response. During the admission the team performs multiple extracorporeal ultraviolet light therapy sessions to achieve improved clinical control of the skin condition under inpatient monitoring. This represents a planned repeat/multiple-session intervention rather than a first-time single exposure. Typical codes: 6A801ZZ
