LONDON and NEW YORK, 14 June 2024 - Renalytix plc (NASDAQ: RNLX) (LSE: RENX) announces that on June 13, 2024 Medicare issued a final Local Coverage Determination ("LCD") for the Company's kidneyintelX.dkd testing. The final LCD can be accessed at LCD - KidneyIntelX and KidneyIntelX.dkd Testing (L39726) (cms.gov), and is effective for dates of service on or after August 1, 2024. The established Medicare price for kidneyintelX.dkd is $950 per test. Distinct CPT Codes (Common Procedural Terminology Codes) have been established for kidneyintelX.dkd and is published in CMS' 2024 Clinical Lab Fee Schedule.

The LCD specifies coverage for use of kidneyintelX.dkd for patients with diagnosed Type 2 diabetes and Stage 1-3b Chronic Kidney Disease is reasonable and necessary. Any specified limitations for use conform to the U.S. Food and Drug Administration ("FDA") label for kidneyintelX.dkd. The LCD was issued by National Government Services ("NGS"). NGS is a subsidiary of Elevance Health, Inc. (previously Anthem, Inc.), a Medicare Administrative Contractor responsible for claims processing for testing performed in the Company's New York City laboratory.

"With final Medicare Coverage, an FDA authorization, and an April recommendation in the international clinical guidelines, kidneyintelX.dkd is poised to be a preventative medicine standard for 14 million people in the United States living with diabetes and kidney disease. We expect this Medicare coverage will prompt additional major coverage decisions and help accelerate testing adoption," said James McCullough CEO of Renalytix. "We remain focused on incremental sales growth in targeted US regions with a now significantly lower cost of operations."
