Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 97028 covers

This code covers therapeutic application of ultraviolet light to one or more treatment areas. Physical therapists and other qualified therapy professionals may use it as a modality within a plan of care, including for a documented skin or tissue condition. The record should identify the treated area, the reason for treatment, and the ultraviolet intervention provided.

Report the service for the ultraviolet modality actually delivered, not for infrared, ultrasound, or another physical agent. It is an untimed modality, so report one unit for the treatment session rather than counting 15-minute increments. Documentation should support the clinical purpose and distinguish the modality from other services furnished that day. CMS treats it as a therapy service without a professional-component modifier split. Under the therapy multiple procedure payment reduction, practice expense is reduced for the second and later therapy units furnished on the same day.
