Recent Developments in 308nm Phototherapy Regulation

CPT Code Expansion for 308nm Treatment

In May 2025, the American Medical Association approved a major revision to CPT codes 96920-96922, expanding insurance reimbursement eligibility for 308nm excimer laser treatments beyond psoriasis to include multiple inflammatory and autoimmune skin conditions, including vitiligo, atopic dermatitis, alopecia areata, lichen planus, and cutaneous T-cell lymphoma -3 -7.

This change:

Aligns CPT codes with current FDA clearances and commercial payer coverage guidelines
Reduces systemic denials and the need for prior authorizations
Expands domestic market access from approximately 10 million psoriasis patients to over 30 million potential patients -3-7

While this specifically addresses in-office excimer laser treatment, it reflects the growing recognition of 308nm phototherapy's broader clinical utility and reinforces its established safety and efficacy profile.

Industry Leadership

The CPT code update resulted from a formal application by STRATA Skin Sciences in collaboration with leading dermatology experts, including Dr. Mark Lebwohl (Past President of the American Academy of Dermatology), Dr. Pearl Grimes (President of the Global Vitiligo Foundation), and Dr. Elisabeth Richard (Johns Hopkins University) -3. This collaboration underscores the established place of 308nm technology in dermatologic care.

The Bottom Line—FDA Clearance Is Your Safety Guarantee

When evaluating a home 308nm phototherapy device, FDA clearance is not a marketing badge—it is a regulatory requirement for any device legally sold in the United States for treating medical conditions. It represents:

Independent verification that the device meets minimum safety and effectiveness standards
Legal accountability for the manufacturer
Access to post-market surveillance and recall protections
Confidence that the device delivers what it claims

Devices lacking FDA clearance operate in a regulatory gray area. They may be unsafe, ineffective, or both. The modest cost savings of an uncertified device are never worth the risk of burns, ineffective treatment, or delayed care.

A Practical Checklist for Your Purchase

Question	What to Verify
Is the device FDA-cleared?	Search the FDA 510(k) database or ask the manufacturer for their 510(k) number
Is the device Class II?	UV dermatologic devices are correctly classified as Class II -4
Does the device specify 308nm?	The cleared device should be indicated for 308nm phototherapy
Are safety features present?	Timer, eyewear, stable design, clear instructions
Is the manufacturer reputable?	Established companies with transparent regulatory documentation

Conclusion: Informed Choice Is Safe Choice

Understanding FDA clearance transforms you from a passive consumer into an informed partner in your healthcare. The regulatory framework governing home 308nm phototherapy devices exists to protect you—to ensure that the light reaching your skin is the right wavelength, at the right dose, delivered safely.

Before you invest in a home phototherapy device, take the time to verify its FDA status. Search the database. Ask for the 510(k) number. Read the labeling. If a manufacturer cannot or will not provide this information, consider that silence your answer—and look elsewhere.

Your skin deserves nothing less than a device that has met the FDA's standards for safety and effectiveness. With proper verification, you can proceed with confidence, knowing that your chosen tool is backed by regulatory science and designed to support your treatment journey safely.
