TL;DR: UnitedHealthcare modified its percutaneous ventricular assist device coverage policy, effective October 1, 2025. Here's what billing teams need to do.
UnitedHealthcare updated its Medicare Advantage medical policy for percutaneous ventricular assist devices, affecting CPT codes 33990, 33991, and 33995. The policy under code percutaneous-ventricular-assist-device sets strict medical necessity criteria for device insertion — and if your claims don't reflect those criteria precisely, denials follow fast. This is a high-stakes policy for cardiology and cardiac surgery billing teams, and the October 1, 2025 effective date is already here.

UnitedHealthcare Percutaneous Ventricular Assist Device Coverage Criteria and Medical Necessity Requirements 2025
The UHC percutaneous ventricular assist device coverage policy is one of the more restrictive device policies in Medicare Advantage. UnitedHealthcare covers percutaneous insertion of an endovascular cardiac assist device — billed under CPT 33990, 33991, or 33995 — only in three specific life-threatening situations.
Here are the three covered indications, pulled directly from the policy:
| # | Covered Indication |
|---|---|
| 1 | Cardiogenic shock (ICD-10: R57.0) |
| 2 | Severe decompensated heart failure with threatening multi-organ failure (ICD-10: I50.21, I50.23, I50.41, I50.43, and related acute/acute-on-chronic codes) |
| 3 | Complications or disturbances of the circulatory system intra-operatively or postoperatively (ICD-10: I97.110, I97.111, I97.130, I97.131, I97.710, I97.711, I97.790, I97.791, I97.88, I97.89) |
There's a fourth condition layered on top of all three: an intra-aortic balloon pump (IABP) must not be expected to be sufficient. If the clinical record doesn't document why IABP was inadequate or contraindicated, you're exposed to a medical necessity denial.
The policy also requires strict adherence to FDA approval guidelines. That's not a throwaway line. If the device was used off-label — or if the documentation doesn't explicitly tie the use to an FDA-approved indication — UHC has grounds to deny. Put that in your pre-submission checklist now.
On the prior authorization side: the policy doesn't explicitly list prior authorization requirements in the criteria section, but given the high-cost nature of these devices and the tight medical necessity criteria, assume PA is required and verify with UHC before the procedure wherever operationally possible. If you're billing for emergent placements where PA isn't feasible, document the emergent circumstances in full.
There is no CMS National Coverage Determination (NCD) for percutaneous ventricular assist devices. That means there's no federal floor to fall back on. Coverage is governed by Local Coverage Determinations (LCDs) and Local Coverage Articles (LCAs) where they exist — which varies by Medicare Administrative Contractor (MAC) jurisdiction. For states and territories without an applicable LCD or LCA, UHC's policy criteria above apply directly.
Check your MAC's local coverage determination before billing. If your region has an LCD for percutaneous ventricular assist devices, that LCD controls — not the UHC default criteria. Mixing these up is a fast path to a claim denial.
UnitedHealthcare Percutaneous Ventricular Assist Device Exclusions and Non-Covered Indications
The policy language is deliberate: the phrase "until the literature clearly demonstrates the efficacy of the treatment approach" precedes the entire coverage framework. That's not incidental wording. It signals that UHC views this technology as provisionally covered under limited conditions — not as a broadly established standard of care.
Any percutaneous ventricular assist device insertion that falls outside the three covered indications is not considered reasonable and necessary. That means elective hemodynamic support during high-risk PCI — a common real-world use of devices like the Impella — doesn't automatically qualify here. The clinical scenario has to map to cardiogenic shock, severe decompensated heart failure with threatening multi-organ failure, or intraoperative/postoperative circulatory complications.
If your cardiologists are using these devices for prophylactic support during complex coronary intervention without evidence of cardiogenic shock or multi-organ failure risk, those claims are vulnerable. Talk to your compliance officer and medical director before October 1, 2025 claims go out the door.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Cardiogenic shock | Covered | R57.0, CPT 33990/33991/33995 | IABP must be insufficient; FDA guidelines must be followed |
| Severe decompensated heart failure with threatening multi-organ failure | Covered | I50.21, I50.23, I50.41, I50.43, I50.84, CPT 33990/33991/33995 | Acute or acute-on-chronic presentations; chronic-only codes are higher-risk without acute component |
| Intraoperative circulatory complications | Covered | I97.710, I97.711, I97.790, I97.791, I97.88, CPT 33990/33991/33995 | Must occur during surgery; document intraoperative timing clearly |
| Postoperative circulatory complications | Covered | I97.110, I97.111, I97.130, I97.131, I97.89, CPT 33990/33991/33995 | Postcardiotomy syndrome (I97.0) also listed; tie to specific surgical procedure |
| Elective hemodynamic support / prophylactic high-risk PCI support | Not Covered | — | Falls outside the three covered indications; no explicit coverage pathway |
| Use when IABP expected to be sufficient | Not Covered | — | Policy requires IABP inadequacy to be clinically established |
| Use outside FDA approval guidelines | Not Covered | — | Off-label use disqualifies the claim |
| Chronic stable heart failure without acute decompensation | Higher denial risk | I50.22, I50.32, I50.42 | Chronic-only codes without acute component don't meet the "threatening multi-organ failure" threshold |
UnitedHealthcare Percutaneous Ventricular Assist Device Billing Guidelines and Action Items 2025
The percutaneous ventricular assist device billing guidelines under this policy require tight coordination between your clinical documentation team and your coders. Here's what to do now.
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for CPT 33990, 33991, and 33995 immediately. The effective date is October 1, 2025 — that means claims already in your queue may be affected. Pull every open claim for these codes and confirm the ICD-10 diagnosis code maps to one of the three covered indications. |
| 2 | Add IABP inadequacy documentation to your pre-bill checklist. This is the criterion most likely to cause silent denials. The clinical note must explicitly state why external counterpulsation was not expected to be sufficient. "Impella placed for hemodynamic support" is not enough. The cardiologist's note needs to address IABP specifically. |
| 3 | Verify your MAC's local coverage determination before defaulting to UHC criteria. If a local coverage determination exists for your jurisdiction, it governs. Contact your MAC or check the CMS LCD database for your contractor's current LCD on percutaneous ventricular assist devices. Don't assume UHC's default criteria apply until you've confirmed there's no LCD for your state. |
| 4 | Flag chronic heart failure ICD-10 codes as reimbursement risks. Codes like I50.22 (chronic systolic heart failure), I50.32 (chronic diastolic heart failure), and I50.42 (chronic combined heart failure) appear in the covered code set — but without a documented acute decompensation component, they're weak support for the "threatening multi-organ failure" criterion. If your patient has chronic HF with an acute exacerbation, code the acute-on-chronic presentation (I50.23, I50.33, I50.43) instead. |
| 5 | Confirm FDA approval alignment in the procedure documentation. Your coder and billing team can't fix an FDA compliance issue after the fact. Build a pre-bill step that confirms the device used was FDA-approved for the documented indication. Impella devices, for example, have specific FDA-cleared indications — make sure the clinical scenario matches. |
| 6 | Treat prior authorization as required for non-emergent cases. The policy doesn't publish a PA requirement in this section, but UHC Medicare Advantage frequently requires PA for high-cost cardiovascular procedures. For planned or semi-elective placements, get PA before the procedure. For emergent cases, document the emergent circumstances fully and submit the PA retroactively per UHC's emergency procedure protocol. |
| 7 | If your volume of these procedures is significant, loop in your compliance officer before year-end. The policy's "until the literature clearly demonstrates efficacy" framing is a signal that UHC is watching this category. High-volume billers for CPT 33990–33995 are more likely to draw audit attention. A prospective audit of your documentation practices now is cheaper than a retrospective recovery demand later. |

A Note on Code Selection Risk
The ICD-10 code list here includes both acute and chronic presentations of heart failure. Don't treat the presence of a code on this list as automatic coverage approval. UHC's medical necessity criteria require a life-threatening situation — that's a clinical standard, not just a code match. Unspecified codes like I50.9 (heart failure, unspecified) and I51.9 (heart disease, unspecified) are the weakest options on this list. Use them only when more specific coding genuinely isn't supported by the documentation. Unspecified codes paired with high-cost procedure codes invite scrutiny.
