Physical therapy
Reports ultraviolet light applied as a therapeutic modality to one or more areas during a documented rehabilitation or treatment session.
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.

Across 109 of 109 CMS payment localities with a supported office rate, 97028 ranges from $7.43 in Arkansas to $10.85 in San Jose-Sunnyvale-Santa Clara (San Benito Cnty). This is a geographic range, not an average.
The code’s RVUs stay the same in these comparisons. Geographic adjustments to work, practice expense and malpractice change the dollar amount. A city name alone may not identify the payment area for a service address.

97028 represents ultraviolet application. Use 97026 when infrared is the modality actually delivered.
No. It is an untimed modality; report one unit for the treatment session, not units based on elapsed time.
No. CMS identifies this as a therapy service for which the professional-component modifier does not apply.
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.
When multiple therapy units are furnished on the same day, CMS reduces practice expense for the second and later units.
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
