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.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

97028 billing questions

How is this different from infrared therapy?

97028 represents ultraviolet application. Use 97026 when infrared is the modality actually delivered.

Is 97028 billed in 15-minute units?

No. It is an untimed modality; report one unit for the treatment session, not units based on elapsed time.

Should modifier 26 be appended?

No. CMS identifies this as a therapy service for which the professional-component modifier does not apply.

What documentation supports the service?

Record the clinical purpose, the area treated, and that ultraviolet light was applied. The documentation should distinguish it from any other modality performed during the visit.

How does the therapy multiple procedure reduction affect payment?

When multiple therapy units are furnished on the same day, CMS reduces practice expense for the second and later units.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
