About 96921: Excimer laser treatment for psoriasis, 250–500 square centimeters
Targeted excimer laser treatment for psoriasis is reported when the total skin area treated in a session measures 250–500 square centimeters.
This service uses an excimer laser to deliver targeted ultraviolet light to psoriasis plaques, limiting exposure of surrounding uninvolved skin. Dermatologists and other qualified practitioners typically perform the treatment in an office setting. The treated area may include plaques on one or more body sites; the code level is based on the total area treated, not the number of plaques or body regions.
Select 96921 when the session’s total treated area is 250–500 square centimeters. Document the psoriasis diagnosis, sites treated, area measurement, and treatment performed. This code has a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate for this area-based service. CMS does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

96921 billing questions
How is 96921 distinguished from 96920 and 96922?
Choose the level by the total skin area treated during the session: 96921 covers 250–500 square centimeters. The neighboring codes cover smaller and larger treatment areas.
Should separate plaques be reported as separate units?
Select the code using the total treated area across the session, rather than counting plaques or body sites as units. Document how the treated area was determined.
Can modifier 50 be used when plaques are treated on both sides of the body?
No. The code is selected by total treated area, and CMS identifies bilateral adjustment as inappropriate for this service.
What same-day care is included in the global period?
The 0-day global period includes same-day preoperative and postoperative care. CMS applies the multiple procedure reduction when other procedures are performed in the same session.
What documentation supports reporting 96921?
Record the psoriasis diagnosis, body sites treated, total area treated in square centimeters, and the excimer laser treatment performed.
