    Transitional Coverage for Emerging Technologies(TCET)

    In one line
    CMS pathway providing time-limited Medicare coverage for FDA-designated Breakthrough Devices.
    Definition
    TCET is a voluntary pathway providing predictable, time-limited national Medicare coverage for selected Breakthrough Devices, paired with an evidence development plan to inform a longer-term coverage determination. CMS finalized TCET in August 2024. Manufacturers of FDA-designated Breakthrough Devices in eligible Medicare benefit categories can nominate their device, and CMS accepts a limited number per year. CMS aims to finalize an NCD within six months of FDA authorization, and coverage is reviewed again once the agreed evidence gaps are filled.
    Why it matters
    TCET replaced the unimplemented MCIT rule and is intended to shrink the gap between FDA market authorization and Medicare coverage for high-impact devices.
    Common pitfalls
    • •A common mistake is assuming TCET guarantees permanent Medicare coverage; it provides time-limited coverage tied to evidence development.
    • •Failing to adhere to the evidence development plan specified under TCET can jeopardize continued coverage.
    • •Misinterpreting the "breakthrough device" designation as an automatic qualifier for TCET without meeting additional CMS criteria is a pitfall.

    Why compare MedTech terms side by side?

    MedTech terminology is full of pairs that look interchangeable but carry very different regulatory, clinical, and commercial consequences. Picking the wrong framework, pathway, or standard early in a project can add months to a submission, invalidate clinical evidence, or trigger an audit finding. Side-by-side comparison is the fastest way to surface those differences before they become costly mistakes.

    Each comparison on this page pulls from the same vendor-neutral, sourced definitions used throughout the MedTech Terms glossary. You see the one-line summary, the formal definition, why it matters in practice, common pitfalls, and the primary sources (FDA guidance, EU MDR/IVDR articles, ISO/IEC standards, MDCG documents, IMDRF principles) that back each entry. That makes the comparison defensible in regulatory strategy memos, design reviews, and submission narratives.
