The US Centers for Medicare and Medicaid Services (CMS) has launched the first operational component of its HealthTech Ecosystem initiative. The Medicare App Library, the centralised directory at the core of the initiative, went live in mid-April 2026 with a first set of vetted apps available to the roughly 69 million Americans on Medicare. Welldoc, January AI, Flexpa and HealthEx are listed; Zocdoc, Noom, Polygon Health and Xealth are among the companies still completing the vetting steps. More than 700 organisations have signed the HealthTech Ecosystem pledge since the initiative was announced in July 2025, with at least 50 of them building patient-facing applications against the deadline.
Three priority use cases shape the first wave:
- Eliminating manual paperwork at clinical check-in through FHIR-based exchange (Flexpa is the early example)
- Conversational AI assistants for navigation and guidance (Microsoft's Copilot is in the demo set)
- Diabetes, obesity and chronic disease management (Vida Health, Virta Health, Welldoc, January AI)
The Library is a regulated directory rather than a medical-device certification scheme. CMS is not assessing clinical efficacy; it is setting baseline requirements for identity verification, FHIR-based data exchange, and external evaluation. The technical requirements for inclusion (FHIR-based exchange combined with federated identity verification) correspond to standards that have been developing in US health-information policy since the 21st Century Cures Act, and may be relevant to patient-data-access architectures beyond Medicare.
The listing requirements reported by CMS are: (1) signing the HealthTech Ecosystem pledge; (2) integrating identity verification through ID.me or CLEAR; (3) connecting to a CMS-aligned network for FHIR-based health-data exchange; and (4) completing an external evaluation through either the Digital Medicine Society (DiMe) or the CARIN Alliance, covering security, privacy, clinical evidence, usability, and equity. Data is reported to flow directly to applications from CMS-aligned networks, with eHealth Exchange and b.well Connected Health named as infrastructure partners. The patient, rather than the insurer, authorises each connection.
January AI's CEO Noosheen Hashemi is quoted in the CMS press release: "Medicare beneficiaries now have new options to connect their health data to applications that translate it into meaningful, personalised insights." Whether the Library is taken up at scale by Medicare beneficiaries is a separate question, and active-use figures had not been published at the time of writing.
