Why CDNA stock is up today
CareDx Inc. (CDNA) surged by 35.60% to $40.34 in a single session, driven by the finalization of Medicare coverage for its molecular transplant surveillance tests. The policy change, which grants broad coverage for kidney, heart, and lung transplant monitoring services, has generated optimism about the company’s long-term revenue potential. The stock opened with a 2.7% gap and climbed steadily throughout the session, peaking at $40.38 before settling near the high.
What Happened
Medicare finalized a Local Coverage Determination (LCD) that confirms reimbursement for CareDx’s molecular tests used in monitoring solid organ transplants. The policy, which becomes effective on August 30, allows up to six tests in the first year and four annually in years two and three. This development provides increased clarity and stability for CareDx, which has been working to expand its market reach in the transplant surveillance space. The news was widely reported and contributed to a rally in the stock, with shares jumping as much as 18% in early coverage.
The CEO of CareDx, John Walter, has sold shares in recent weeks, with two transactions reported in June 2026. Additionally, a director, Hannah Valantine, also sold shares on June 15. These insider sales occurred before the Medicare announcement and do not appear to have influenced the stock’s recent move.
What The Data Shows
The stock opened at $30.55 and climbed to a session high of $40.38, with volume reaching 3.7 million shares, nearly 4.8 times the 3-month average. The move pushed the stock beyond its 52-week high of $30.00, reaching a new peak of $40.38. CareDx remains unprofitable, with a trailing 12-month net loss and a market cap of $1.5 billion. The stock has a beta of 2.43, indicating it is more volatile than the broader market.
What To Watch
CareDx is scheduled to report its second quarter 2026 financial results on July 30, 2026. The upcoming earnings release will provide insight into how the Medicare coverage change is already impacting revenue and customer adoption. Investors will also monitor the stock’s performance in the coming weeks for signs of continued momentum or profit-taking.
