    CPT Codes(CPT)

    AMA-maintained codes that describe medical procedures and services.
    Definition
    Current Procedural Terminology codes are five-digit numeric codes maintained by the American Medical Association that describe physician and other professional services. Category I codes are permanent; Category III codes are temporary tracking codes for emerging services. Payment for a CPT code depends on its setting: Physician Fee Schedule values for professional work, OPPS APCs for hospital outpatient care and ASC rates for surgery centers. Using the wrong code or an unlisted code can delay payment. Device companies often support customers with coding guides, but these must be accurate and avoid suggesting codes that do not fit the service.
    Why it matters
    Without an applicable CPT code, physicians cannot bill for procedures involving a new device. Securing a Category III code is often the first reimbursement milestone; conversion to Category I follows demonstrated utilization and evidence.
    Common pitfalls
    • •Assuming an existing CPT code adequately describes a novel procedure - payers can deny based on miscoding.

    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.
