Medicare Benefit Policy Manual Chapter 16: General Exclusions from Coverage

Medicare covers most of the cardiovascular care that matters most — but understanding what it excludes is as important for navigating the system as understanding what it covers. Chapter 16 of the Medicare Benefit Policy Manual establishes 16 categories of exclusion under the statutory authority of Section 1862 of the Social Security Act. The June 2025 revision (Rev. 13272) is the governing document for coverage determinations.

The most consequential exclusion category for cardiovascular care is the “not reasonable and necessary” standard: Medicare will not pay for services that are not “reasonable and necessary for the diagnosis or treatment of illness or injury.” This is the basis for prior authorization requirements, coverage denials for off-label or experimental treatments, and disputes over medical necessity. It is not a clinical determination — it is an administrative one that operates on its own logic.

For preventive cardiovascular care specifically, the manual provides a “routine services” exclusion with important carve-outs. Lipid screening, diabetes screening, cardiovascular screening, and the Annual Wellness Visit are covered despite the general exclusion of routine exams. This is where the coverage landscape affects the practical path to diagnosis: coronary calcium scoring (CAC), for instance, is not in the enumerated carve-outs for most indications, creating an access barrier for a test with strong evidence of cardiovascular risk reclassification.

The custodial versus skilled care distinction matters for cardiac rehabilitation and post-MI care: Medicare covers skilled nursing if the care requires trained medical or paramedical personnel; personal care and assistance with activities of daily living are excluded as custodial. The line between them is frequently contested in post-acute cardiovascular recovery.

The manual is a regulatory document, not a clinical one. It establishes coverage, not clinical appropriateness — and the two frequently diverge in cardiovascular medicine. Understanding where that divergence occurs is essential for patients and clinicians attempting to access evidence-based care within the Medicare system.

We rate the evidence moderate for this source. The CMS Medicare Benefit Policy Manual Chapter 16 establishes the legal framework for Medicare coverage exclusions — authoritative for coverage determinations, but a regulatory document rather than clinical evidence.
