20.39 –Cardiac Contractility Modulation (CCM) for Heart Failure (HF)
(Rev. 13716; Issued: 04-03-26; Effective: 10-28-25; Implementation: 04-06-26)
A. General
Cardiac Contractility Modulation (CCM) is used in the treatment of heart failure (HF).
B. Nationally Covered Indications
The Centers for Medicare & Medicaid Services (CMS) covers CCM for HF management
under Coverage with Evidence Development (CED) when furnished according to a Food
and Drug Administration (FDA) market-authorized indication and all of the following
conditions are met:
7. Patient Criteria
Patients must meet the FDA market-authorized indications for use and remain
symptomatic despite at least 3 months of optimized guideline-directed medical therapy
(GDMT) as determined by the heart team prior to CCM implantation.
Patients are excluded from coverage if they meet any of the following criteria:
• Meet any of the contraindications in the FDA labeling; or,
• Have had a heart transplant; or,
• Are younger than 18 years old
8. CED Study Criteria
The CCM and related items and services are furnished in the context of a CMS-approved
CED study. CMS-approved CED study protocols must: include only those patients who
meet the criteria in section B.1; and include all of the following:
a) Primary outcomes of all-cause mortality, HF hospitalizations, or a composite of these,
through a minimum of 24 months. Each component of a composite outcome must be
individually reported.
b) An active comparator.
c) A care management plan that identifies members, roles, and responsibilities of the
clinical team that performs the follow-up CCM patient management.
d) Design sufficient for subgroup analyses by:
• Age (Stratify <65, 65-74, 75+)
• Other clinically important patient demographic factors
• Ischemic cardiomyopathy versus non-ischemic cardiomyopathy;
• No CRT, CRT (cardiac resynchronization therapy);
• Left ventricular ejection fraction (LVEF) ≥35% versus <35%;
• Systolic blood pressure ≥ median versus < median;
• Diabetic vs non-diabetic
e) In addition, CMS-approved CED studies must adhere to the following scientific
standards (criteria 1-17 below) that have been identified by the Agency for Healthcare
Research and Quality (AHRQ) as set forth in Section VI. of CMS’ Coverage with
Evidence Development Guidance Document, published August 7. 2024 (the “CED
Guidance Document”) https://www.cms.gov/medicare-coverage-database/view/medicare-
coverage-document.aspx?mcdid=38
1. Sponsor/Investigator: The study is conducted by sponsors/investigators with the
resources and skills to
complete it successfully.
2. Milestones: A written plan is in place that describes a detailed schedule for completion
of key study
milestones, including study initiation, enrollment progress, interim results reporting, and
results reporting, to ensure timely completion of the CED process.
3. Study Protocol: The CED study is registered with ClinicalTrials.gov and a complete
final protocol, including the statistical analysis plan, is delivered to CMS prior to study
initiation. The published protocol includes sufficient detail to allow a judgment of
whether the study is fit-for-purpose and whether reasonable efforts will be taken to
minimize the risk of bias. Any changes to approved study protocols should be explained
and publicly reported.
4. Study Context: The rationale for the study is supported by scientific evidence and
study results are expected to fill the specified CMS-identified evidence deficiency and
provide evidence sufficient to assess health outcomes.
5. Study Design: The study design is selected to safely and efficiently generate valid
evidence of health
outcomes. The sponsors/investigators minimize the impact of confounding and biases on
inferences through
rigorous design and appropriate statistical techniques. If a contemporaneous comparison
group is not included, this choice should be justified, and the sponsors/investigators
discuss in detail how the design contributes useful information on issues such as
durability or adverse event frequency that are not clearly answered in comparative
studies.
6. Study Population: The study population reflects the demographic and clinical diversity
among the Medicare beneficiaries who are the intended population of the intervention,
particularly when there is good clinical or scientific reason to expect that the results
observed in premarket studies might not be observed in older adults or subpopulations
identified by other clinical or demographic factors.
7. Subgroup Analyses: The study protocol explicitly discusses beneficiary subpopulations
affected by the item or service under investigation, particularly traditionally
underrepresented groups in clinical studies, how the inclusion and exclusion requirements
effect enrollment of these populations, and a plan for the retention and reporting of said
populations in the trial. In the protocol, the sponsors/investigators describe plans for
analyzing demographic subpopulations as well as clinically relevant subgroups as
identified in existing evidence. Description of plans for exploratory analyses, as relevant
subgroups emerge, are also included.
8. Care Setting: When feasible and appropriate for answering the CED question, data for
the study should come from beneficiaries in their expected sites of care.
9. Health Outcomes: The primary health outcome(s) for the study are those important to
patients and their
caregivers and that are clinically meaningful. A validated surrogate outcome that reliably
predicts these
outcomes may be appropriate for some questions. Generally, when study sponsors
propose using surrogate
endpoints to measure outcomes, they should cite validation studies published in peer-
reviewed journals to
provide a rationale for assuming these endpoints predict the health outcomes of interest.
The cited validation studies should be longitudinal and demonstrate a statistical
association between the surrogate endpoint and the health outcomes it is thought to
predict.
10. Objective Success Criteria: In consultation with CMS and AHRQ,
sponsors/investigators establish an
evidentiary threshold for the primary health outcome(s) to demonstrate clinically
meaningful differences with sufficient precision.
11. Data Quality: The data are generated or selected with attention to provenance, bias,
completeness, accuracy, sufficiency of duration of observation to demonstrate durability
of health outcomes, and sufficiency of sample size as required by the question.
12. Construct Validity: Sponsors/investigators provide information about the validity of
drawing warranted conclusions about the study population, primary exposure(s)
(intervention, control), health outcome measures, and core covariates when using either
primary data collected for the study about individuals or proxies of the variables of
interest, or existing (secondary) data about individuals or proxies of the variables of
interest.
13. Sensitivity Analyses: Sponsors/investigators will demonstrate robustness of results by
conducting prespecified sensitivity testing using alternative variable or model
specifications as appropriate.
14. Reporting: Final results are provided to CMS and submitted for publication or
reported in a publicly accessible manner within 12 months of the study’s primary
completion date. Wherever possible, the study is submitted for peer review with the goal
of publication using a reporting guideline appropriate for the study design and structured
to enable replication. If peer-reviewed publication is not possible, results may also be
published in an online publicly accessible registry dedicated to the dissemination of
clinical trial information such as ClinicalTrials.gov, or in journals willing to publish in
abbreviated format (e.g., for studies with incomplete results).
15. Sharing: The sponsors/investigators commit to making study data publicly available
by sharing data,
methods, analytic code, and analytical output with CMS or with a CMS-approved third
party. The study should comply with all applicable laws regarding subject privacy,
including 45 CFR § 164.514 within the regulations promulgated under the Health
Insurance Portability and Accountability Act of 1996 (HIPAA) and 42 CFR, Part 2:
Confidentiality of Substance Use Disorder Patient Records.
16. Governance: The protocol describes the information governance and data security
provisions that have been established to satisfy Federal security regulations issued
pursuant to HIPAA and codified at 45 CFR Parts 160 and 164 (Subparts A & C), United
States Department of Health and Human Services (HHS) regulations at 42 CFR, Part 2:
Confidentiality of Substance Use Disorder Patient and HHS regulations at 45 CFR Part
46, regarding informed consent for clinical study involving human subjects. In addition to
the requirements under 42 CFR and 45 CFR, studies that are subject to FDA regulation
must also comply with regulations at 21 CFR Parts 50 and 56 regarding the protection of
human subjects and institutional review boards, respectively.
17. Legal: The study is not designed to exclusively test toxicity or disease
pathophysiology in healthy individuals, although it is acceptable for a study to test a
reduction in toxicity of a product relative to standard of care or an appropriate
comparator. For studies that involve researching the safety and effectiveness of new
drugs and biological products aimed at treating life-threatening or severely debilitating
diseases, refer to additional requirements set forth in 21 CFR § 312.81(a).
Consistent with section 1142 of the Social Security Act, AHRQ supports clinical research
studies that CMS determines meet all the criteria and standards identified above.
C.
