 determines the process by which the rate is set and is not an indication of Medicare coverage. Since 2022, the rate for DecisionDx-Melanoma is set annually based upon the median private payor rate for the first half of the second preceding calendar year. For example, the rate for 2024 was set using median private payor rate data from January 1, 2022 to June 30, 2022. Our rate for 2024 was $7,193 per test and remains at $7,193 for 2025.

DecisionDx‑SCC

We issue our DecisionDx-SCC tests from our Pittsburgh and Phoenix laboratories. Palmetto’s MolDX (“MolDX”) program oversees MAAA tests that are reported from our Phoenix laboratory and Noridian is the MAC responsible for administering Medicare claims for test reports issued by our Phoenix laboratory. Novitas is the MAC responsible for administering Medicare claims for test reports issued by our Pittsburgh laboratory.

DecisionDx-SCC has met “new ADLT” status since 2022. Effective July 1, 2023 and through March 31, 2024, CMS set the initial period rate equal to the list price of $8,500 per test. Effective April 1, 2024, and through December 31, 2025, the published Clinical Laboratory Fee Schedule (“CLFS”) rate for DecisionDx-SCC will continue at $8,500 based on the median private payor rates received between July 1, 2023 and November 30, 2023.

On July 4, 2024, Palmetto and Noridian finalized an LCD recommending no coverage for DecisionDx-SCC with an effective date of August 18, 2024. On January 9, 2025, Novitas finalized an oncology biomarker LCD, Genetic Testing for Oncology: Specific Tests, which also lists DecisionDx-SCC as non-covered; that LCD became effective on April 24, 2025.

In July 2025, we submitted reconsideration requests for both the Novitas and MolDX LCDs. Novitas subsequently confirmed that our request for DecisionDx-SCC was valid. MolDX also subsequently confirmed that our request for DecisionDx-SCC was valid and that the test has been placed on its waiting list, with an Open Meeting date to be determined. These confirmations represent another procedural step in the reconsideration process, but
