Medicare Now Lets CareDx Bill Six Kidney Surveillance Tests in a Transplant's First Year
Hypothesis Opus 5 · Research Opus 5 · Writing Opus 5 · Prompt v1.6
The price of a molecular test is not set by hospitals or by patients. It is set by a Medicare administrative contractor, and in 2026 that contractor moved three times — each move landing in a share price within a single session.
CareDx's testing revenue rose 61% to $100m after a July coverage rule fixed how many surveillance tests it may bill per transplant patient; most of that growth came from price realization rather than demand. Adaptive lifted clonoSEQ's average selling price 7% while a September guideline update named the assay preferentially. Veracyte, which grew testing revenue 19% at a 15.3% operating margin, fell 22.5% in one session because its two newest products have no Medicare price yet.
The two companies whose rulings landed have already been paid for. The one still waiting is the cheapest of the three.

Forward fiscal years only. Blank means no analyst coverage for that year.
On 16 July a Medicare contractor published the final local coverage determination for molecular testing of solid-organ transplant rejection, and it did something a commercial customer never does: it wrote down how many tests a doctor may order. Up to six AlloSure Kidney surveillance tests in a patient's first post-transplant year, four in each of the next two, twelve in year one for lung. CareDx, which sells those donor-derived cell-free DNA tests along with the AlloMap heart gene-expression assay, rose 35.6% that session. The policy took effect on 30 August.
That is the machinery underneath this corner of diagnostics. A laboratory with an FDA-cleared or Medicare-covered assay does not negotiate a price and does not set a quantity; the MolDX program does both, and the rest of the payer market follows. The money at stake is being repriced right now: on 21 September the Centers for Medicare & Medicaid Services posted preliminary CY2027 laboratory fee schedule rates that cut hundreds of codes by as much as 15% and are meant to save roughly $1bn a year. They are finalized in November and take effect 1 January.
The company that has already been repriced twice
CareDx knows what an adverse ruling costs. A MolDX billing article in March 2023 limited reimbursement to one test per encounter; the company paused Medicare submissions on AlloSure Kidney, withholding about 3,200 tests worth roughly $8.9m of quarterly revenue, and full-year revenue fell 12.9% in 2023 to $280.3m. "We believe publication of this draft policy solidifies coverage for surveillance testing," chief executive John Hanna said of the proposal that became this July's final rule.
Second-quarter testing revenue reached $100m against $62m a year earlier on volume up 17%, or about 58,000 tests — roughly $1,720 realized per test, and about two-thirds of the growth came from price rather than units. That realization still sits well below the $2,840 AlloSure rate and $3,240 for AlloMap in the preliminary 2027 schedule, which spared the transplant portfolio while cutting elsewhere; the gap is payer mix. Guidance is now $490m–$500m and the company bought Naveris, whose NavDx head-and-neck cancer assay carries its own Medicare coverage, for $160m up front.
Guidelines are the second gatekeeper
Adaptive Biotechnologies bills clonoSEQ, an FDA-cleared blood-cancer test that finds one malignant cell in a million, at a Medicare rate of $2,007 set through the MolDX gapfill process. It realizes $1,382 — about 69% of that rate — on 36,111 tests, up 43%, with minimal residual disease gross margin at 72% against 64%. "Q2 was an exceptional quarter for Adaptive and a clear validation of our strategy and execution," chief executive Chad Robins told investors on the July call. Guidance went to $268m–$278m.
Then the guideline bodies moved. On 17 September the National Comprehensive Cancer Network's myeloma guidelines added a dedicated MRD testing page naming clonoSEQ; on 25 September the International Myeloma Society defined cure as five years in remission with at least four negative assessments at that sensitivity — a definition that multiplies billable assays per patient. Adaptive's 13.2% thirty-day gain is four sessions, clustered on those dates.
The one still in the queue
Veracyte sells the Afirma thyroid classifier and Decipher prostate test into indications where reimbursement was settled years ago, so its growth has to come from penetration — management puts Decipher at roughly 20% of the low-risk prostate market. It is the best business of the three by margin: testing revenue of $145.7m, up 19%, gross margin 72.2%, operating margin 15.3%, net income of $25.5m against an operating loss a year earlier. Shares fell 22.5% on 31 July anyway. Prosigna's centralized version and the TrueMRD bladder test were left out of guidance pending a MolDX technical assessment and the pricing talks that follow, and Decipher's low-risk volume outlook was trimmed by about 1,000 tests after an NCCN change. "Q2 was a milestone quarter for Veracyte as we launched two new products," chief executive Marc Stapley said on the 30 July call.
The same institution that re-rated Adaptive de-rated Veracyte inside two months. That is the finding: in this segment the business event is a committee document, and the share prices have already discounted the documents that exist. CareDx trades at 53.7x forward earnings — its 30x trailing figure is unusable, containing a $113m gain on the Lab Products sale — after a six-month run of 285%, and consensus has revenue growth decelerating to 6.3% in 2027, treating this year's step-up as one-time. Adaptive's 15.6x forward sales sits above its 14.8x trailing, because a Genentech milestone rolls off, against a consensus 2026 net loss of $85m. Veracyte is at 23.6x forward earnings against 31.4x trailing, 6.1x forward sales and a 4.6% free cash flow yield, and is the laggard of the diagnostics group over twelve months.
What none of this prices is the absence of coverage. GRAIL's Galleri screening test sells for $949 in cash at a gross margin of minus 28%; Medicare cannot pay for multi-cancer screening until 2028. Coverage is the whole margin.
November settles the 2027 rates. CareDx and Adaptive already know what their documents say; Veracyte's has not been written.
