What 96920 covers
This service uses an excimer laser to deliver targeted ultraviolet treatment to psoriasis plaques, commonly in patients with localized disease. Dermatologists and other qualified clinicians may perform it in an office setting; typical treatment sites include discrete plaques on the elbows, knees, or scalp. The laser targets affected skin rather than exposing the whole body to phototherapy.
Choose this code when the total psoriasis area treated during the session is under 250 square centimeters; select the sibling area tier when the treated area is larger. Document the sites and measured area treated, along with the treatment performed. CMS assigns a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is restricted, and co-surgeons and team surgery are not permitted.

96920 billing questions
How do I choose between 96920, 96921, and 96922?
Use the total psoriasis area treated during the session: 96920 is for less than 250 square centimeters, 96921 for 250–500, and 96922 for more than 500.
Does the number of plaques determine the code?
No. Select the code by the total area treated, not by the number of plaques or laser applications. Document the treated sites and area.
Can I report more than one area tier for the same session?
Select the single tier that matches the total area treated during that session; the tiers distinguish the treatment-area ranges.
Does modifier 50 apply when plaques are on both sides of the body?
No. CMS identifies bilateral adjustment as inapplicable to this code, so modifier 50 is inappropriate.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
What same-day care is included, and can an assistant be paid?
The 0-day global period includes same-day preoperative and postoperative care. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
