Summary: The Centers for Medicare & Medicaid Services modified its artificial hearts and related devices coverage policy, retiring the existing policy framework effective May 15, 2026. Here's what billing teams need to know before that date.
CMS artificial hearts coverage policy has been a relatively narrow but financially significant slice of cardiac device billing. The retirement of this policy — rather than a simple update — signals a structural shift in how the Centers for Medicare & Medicaid Services governs reimbursement for total artificial heart (TAH) technology and related implantable cardiac assist devices. This policy does not list specific CPT or HCPCS codes in the available data, so billing teams should pull their current charge capture documentation and cross-reference directly with CMS before May 15, 2026.

CMS Artificial Hearts Coverage Criteria and Medical Necessity Requirements 2026
The CMS artificial hearts coverage policy retirement raises an immediate question: what replaces it? When CMS retires a policy rather than revising it, coverage doesn't automatically disappear. It shifts. Typically, coverage authority moves to local Medicare Administrative Contractor (MAC) discretion or gets absorbed into a broader National Coverage Determination (NCD).
Medical necessity documentation for artificial heart devices has always been demanding. These are high-cost, high-complexity implants — total artificial hearts like the SynCardia device and ventricular assist devices used as bridge-to-transplant or destination therapy. CMS has historically required detailed documentation of end-stage heart failure, failure of other therapies, and patient eligibility criteria before reimbursing for these devices. That bar doesn't get lower just because a policy is retired.
Whether the retirement of this specific coverage policy means CMS is consolidating artificial heart coverage under a broader cardiac device NCD, transferring authority to MACs, or responding to changes in device approvals, your billing team can't assume continuity. Prior authorization requirements, medical necessity thresholds, and coverage criteria may all shift at the MAC level after May 15, 2026.
If your facility bills for artificial heart implants or related cardiac support devices, contact your MAC now. Don't wait until claims start hitting denials.
CMS Artificial Hearts Exclusions and Non-Covered Indications
CMS has historically drawn sharp lines around artificial heart device coverage. The prior coverage policy framework treated certain device configurations and patient profiles as non-covered — particularly devices used outside their FDA-approved indications, implants for patients who didn't meet heart failure staging criteria, and devices deployed in settings outside of CMS-approved facilities.
The policy retirement doesn't erase those exclusion principles. It creates ambiguity around where they now live. If your MAC hasn't issued updated local coverage determinations by May 15, 2026, you're operating in a gap.
Claim denial risk is highest for:
| # | Excluded Procedure |
|---|---|
| 1 | Devices implanted outside of CMS-certified ventricular assist device (VAD) implanting facilities |
| 2 | Cases where bridge-to-transplant intent isn't clearly documented and destination therapy criteria aren't met |
| 3 | Patients who don't meet the documented medical necessity thresholds that existed under the prior policy |
Watch for MAC bulletins between now and the effective date. That's where replacement guidance will most likely appear first.
Coverage Indications at a Glance
Because the policy data does not include specific indication-level criteria from the retired document, the table below reflects the general coverage framework CMS has applied to artificial heart devices based on the prior policy structure. Verify each of these with your MAC before May 15, 2026.
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Total artificial heart as bridge to transplant | Coverage status under review — confirm with MAC | Not listed in available policy data | MAC guidance required post-retirement |
| Ventricular assist device as destination therapy | Coverage status under review — confirm with MAC | Not listed in available policy data | Medical necessity documentation critical |
| Ventricular assist device as bridge to transplant | Coverage status under review — confirm with MAC | Not listed in available policy data | CMS facility certification still applies |
| Implant outside FDA-approved indication | Historically not covered | Not listed in available policy data | Policy retirement does not change non-coverage for off-label use |
| Devices in non-certified facilities | Historically not covered | Not listed in available policy data | Facility eligibility requirements remain in force |
CMS Artificial Hearts and Related Devices Billing Guidelines and Action Items 2026
This is where the retirement designation gets real for your revenue cycle team. A retired policy isn't a lapsed policy — it's an actively restructured one. Here's what to do before May 15, 2026.
| # | Action Item |
|---|---|
| 1 | Pull every open claim involving artificial heart devices and VADs now. Review each one for medical necessity documentation completeness. If a claim is pending with incomplete documentation, resolve it before May 15, 2026. Don't let it carry into the post-retirement period without coverage clarity. |
| 2 | Contact your MAC directly and ask for their position on artificial heart device coverage after the retirement effective date. Ask specifically: Is there a replacement NCD? Has the MAC issued or will it issue a local coverage determination? Do prior authorization requirements change? Get the answer in writing. |
| 3 | Update your charge capture documentation workflows. The policy does not list specific CPT or HCPCS codes in the available data — which means your charge capture team needs to verify the correct codes are mapped to whatever guidance your MAC issues. Don't assume code sets carry over unchanged. |
| 4 | Review your medical necessity attestation templates. CMS artificial heart billing guidelines have always required detailed clinical justification. After a policy retirement, MAC reviewers may apply different or stricter criteria during claims review. Strengthen your attestation language now — document patient history, failed therapies, heart failure staging, and device indication clearly. |
| 5 | Audit facility certification status. CMS has historically tied artificial heart and VAD reimbursement to facility-level certifications. Confirm your facility's certification is current and will remain valid under whatever framework replaces this retired policy. A lapsed certification is an automatic denial. |
| 6 | Loop in your compliance officer and legal counsel before the effective date if your program does significant artificial heart volume. The retirement of a coverage policy — without a clear public replacement document — is exactly the kind of ambiguous situation where unreviewed claims create audit exposure. This isn't generic advice. If your facility implants more than a handful of these devices per year, the financial exposure here is substantial. |
| Previous Version | Current Version |
|---|---|
| Coverage is considered experimental and investigational for all indications | Coverage is considered medically necessary when specific criteria are met |
| Prior authorization is not required | Prior authorization is required for initial treatment |
| Documentation must include clinical history | Documentation must include clinical history |
| Re-review every 24 months | Re-review every 12 months with updated clinical documentation |
CPT, HCPCS, and ICD-10 Codes for Artificial Hearts and Related Devices Under This Policy
This policy does not list specific CPT, HCPCS, or ICD-10 codes in the available data. Do not use this section as a complete code reference for artificial heart device billing.
That's worth stating plainly, because artificial heart billing involves several high-value device and procedure codes that your team is likely already using. The absence of code data in the retired policy document doesn't mean those codes are unaffected — it means the coverage framework governing them is shifting.
Common code categories that typically appear in artificial heart and VAD billing include cardiac device implantation procedure codes, durable medical equipment (DME) classifications for externally worn components, and hospital inpatient procedure codes under the inpatient prospective payment system. Which specific codes apply to your patient population, and how they'll be covered after May 15, 2026, depends entirely on what your MAC publishes before that date.
Do not fabricate or assume codes based on historical billing patterns alone. Pull the current CMS fee schedule, check your MAC's website, and reconcile your charge capture against confirmed post-retirement guidance.
If your billing team needs a definitive code list for artificial heart devices, the correct source after retirement is your MAC's local coverage determination — not this retired CMS policy.
The Real Issue With Retired Policies
Most billing teams treat a policy retirement as a non-event. That's a mistake.
When CMS retires a policy, claims in that space don't automatically get processed under some default standard. They get reviewed under whatever framework the reviewer applies — and in the absence of a clear replacement policy, that framework is inconsistent. One MAC applies the old criteria informally. Another doesn't. A third issues a new LCD. Your claim denial rate tells you which one you're dealing with after the fact.
The artificial heart billing space is also not a high-volume category at most facilities. That cuts both ways. It means fewer teams are watching this closely — which is exactly why the ones that are watching have an advantage. If your cardiothoracic surgery billing team audits this now and your competitors don't, you protect reimbursement they'll lose.
This policy retirement also comes as the artificial heart device market is evolving. FDA clearances for newer total artificial heart systems and next-generation VADs have shifted the clinical landscape over the past several years. CMS policy structures sometimes lag behind device approvals. A retirement without an immediate replacement could reflect CMS working through how to handle newer devices under an updated framework. Watch for NCD activity in the cardiac device space throughout the rest of 2026.
