    Local and National Coverage Determinations from Medicare.
    Definition
    A National Coverage Determination (NCD) is a Medicare-wide policy on whether and under what conditions an item or service is covered. A Local Coverage Determination (LCD) is issued by a Medicare Administrative Contractor (MAC) for its jurisdiction. NCDs bind all Medicare contractors, while LCDs apply only within a MAC's region, so coverage can differ between states until an NCD exists. Medicare Advantage plans must follow NCDs and LCDs but may add utilization management. Manufacturers can request a new NCD or LCD, or a reconsideration, by submitting supporting evidence.
    Why it matters
    Coverage typically begins as LCD policy via one or more MACs; pivotal NCDs (e.g., TAVR, TCAR, TMVR) define the national clinical-evidence and facility/operator standards.
    Common pitfalls
    • •Misinterpreting an LCD as a national policy can lead to denied claims in other jurisdictions.
    • •Failing to consider both NCDs and relevant LCDs when determining coverage for a medical device or service can result in incomplete reimbursement strategies.
    • •Assuming that an absence of an NCD means automatic coverage can lead to significant financial losses if an LCD also denies coverage.
    • •Not understanding the specific evidence requirements outlined in an NCD or LCD can lead to insufficient clinical trial design or data collection activities.

    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.
