Q: Is home phototherapy covered by insurance?

A: Some plans do. Coverage varies by insurer, policy, and location. You will typically need a Letter of Medical Necessity documenting failed previous therapies. Many patients successfully use HSA/FSA funds.

Q: What about the cost of lamp replacement?

A: Excimer lamps typically last thousands of hours (often 5,000–10,000). For a patient treating 3× weekly for 10–15 minutes per session, a lamp may last 2–5 years. Replacement lamps cost $200–$500—a fraction of the ongoing cost of clinic visits.

Q: How does 308nm LED compare cost-wise to excimer?

A: LED devices are generally less expensive to manufacture and may offer lower purchase prices. They also do not require gas replacement, though the LEDs themselves have a rated lifespan -2.

Q: Can I try phototherapy in clinic first before buying a home device?

A: Absolutely. Many dermatologists recommend this approach. A brief course of in-office treatment can:

Confirm that phototherapy works for you
Establish your optimal starting dose
Provide training on proper technique
Build confidence before investing in a home device

Q: What if I stop using the device after a few months?

A: This is the biggest risk to value. If you are uncertain about your commitment, consider a rental or trial program if available, or start with clinic-based treatment. Home phototherapy delivers maximum value only with consistent, long-term use.
