    Coverage with Evidence Development

    Medicare paradigm conditioning coverage on participation in approved clinical studies or registries.

    Reviewed by Christian Espinosa, Founder, Blue Goat CyberLast reviewed May 5, 2026

    Definition

    Under CED, CMS provides coverage for promising items or services on the condition that beneficiaries are enrolled in an approved study or data collection effort that addresses outstanding questions. CED is applied through an NCD, with study requirements described in CMS's CED guidance, and participating facilities must enroll patients in an approved registry or trial. Transcatheter valve replacement, linked to the TVT Registry, is a well known device example. CED decisions can be reconsidered and the study requirement removed once enough evidence exists.
    What the regulation says
    Coverage with Evidence Development (CED) is a mechanism primarily used by the Centers for Medicare & Medicaid Services (CMS) in the United States to provide conditional coverage for medical technologies. This approach enables beneficiaries to access innovative items and services while systematically collecting additional evidence to assess their impact on health outcomes. The conditions for coverage often involve participation in studies or registries, as outlined by CMS policies.

    What this means in practice

    CED is common for novel devices with developing evidence (e.g., TAVR, leadless pacemakers historically). Registry participation requirements influence hospital adoption and total cost of evidence generation.

    Examples

    • A novel cardiac implant receives CED from CMS, requiring all patients receiving the device to be enrolled in a specific post-market registry to collect long-term outcome data.
    • A new diagnostic test is covered under CED, mandating that healthcare providers submit data on patient demographics and test results to a designated database to assess its clinical utility.
    • CMS grants CED for a new cancer therapy, contingent on patients participating in an approved clinical trial that aims to further evaluate its efficacy in a broader patient population.
    Common pitfalls
    • •Manufacturers might underestimate the resources required for data collection and study participation under CED.
    • •Failing to design studies that adequately address the evidence gaps identified by CMS can lead to delays or non-coverage.
    • •Misinterpreting CMS requirements for data submission and study protocols can result in compliance issues.
    • •Assuming that CED implies permanent coverage without the need for submitting conclusive evidence is a common misconception.
    • •Ignoring the impact of CED on market access strategies and product launch timelines can lead to commercial challenges.

    Frequently asked questions

    The primary goal of CED is to facilitate patient access to promising new medical technologies while simultaneously gathering additional clinical evidence to determine their long-term effectiveness and appropriateness for coverage.
