CMS Modifies Coverage for Implantable Pulmonary Artery Pressure Sensors in Heart Failure Management (NCD 378)
The Centers for Medicare & Medicaid Services has modified NCD 378, its national coverage determination for implantable pulmonary artery pressure sensors (IPAPS) used in heart failure management. This update establishes detailed Coverage with Evidence Development (CED) criteria that billing teams, cardiologists, and hospital outpatient departments must understand before submitting claims for these services. If your practice or facility implants or manages patients with PA pressure sensor technology, this policy change is high-priority reading.

What Changed: CMS NCD 378 and IPAPS Coverage Under CED
CMS is covering IPAPS for heart failure management—but exclusively under Coverage with Evidence Development. CED means Medicare will reimburse the implantation and ongoing management of these devices only when services are furnished as part of a CMS-approved clinical study. This is not unconditional coverage. Facilities and physicians that do not operate within an approved CED study protocol will not have a pathway to Medicare reimbursement under this NCD.
The policy applies across three benefit categories: inpatient hospital services, outpatient hospital services incident to a physician's service, and physicians' services. That breadth matters for billing—the same underlying coverage rules govern claims regardless of the setting in which the implant or management service occurs.
This modification is significant because it codifies specific, multi-layered eligibility requirements at the national level. Prior to this update, coverage was less clearly defined. Now, claims reviewers and auditors have an explicit checklist to apply.
IPAPS Medical Necessity Criteria: What CMS Requires
CMS has organized its coverage criteria into three distinct tiers: patient criteria, physician criteria, and CED study criteria. All three must be satisfied for coverage to apply.
Patient Criteria — Seven Required Conditions
A patient must meet all of the following to qualify for covered IPAPS implantation:
| # | Covered Indication |
|---|---|
| 1 | Diagnosis of chronic heart failure of at least three months' duration, with New York Heart Association (NYHA) functional Class II or III documented within the 30 days prior to implantation—regardless of left ventricular ejection fraction (LVEF). |
| 2 | History of HF hospitalization or urgent HF visit (emergency room or outpatient visit requiring IV diuretic therapy) within the past 12 months, or elevated natriuretic peptides within the past 30 days. |
| 3 | Guideline-directed medical therapy (GDMT) for at least three months, with the goal of achieving optimal or maximally-tolerated GDMT before implantation. |
| 4 | Evaluation for—and receipt of, if appropriate—an ICD, CRT-Pacemaker, or CRT-Defibrillator, with any such device implanted at least three months before IPAPS implantation. |
| 5 | No major cardiovascular event (unstable angina, myocardial infarction, PCI, open heart surgery, or stroke) within the three months prior to implantation. |
| 6 | Reliable connectivity access sufficient to ensure daily collection and transmission of IPAPS data from the patient's home to the managing physician. |
| 7 | IPAPS implantation must not occur during a hospital admission for an acute HF episode. |
That last criterion is operationally critical. A patient admitted for acute decompensated heart failure (ADHF) cannot receive a covered implant during that same stay. Facilities will need intake and scheduling protocols that flag this restriction.
Physician Criteria — Specialty and Training Requirements
CMS sets separate requirements depending on the physician's role:
| # | Covered Indication |
|---|---|
| 1 | Referring and managing physicians must be cardiologists with training and experience in heart failure management. |
| 2 | Implanting physicians must have training and experience in pulmonary arterial catheterization and intervention. |
These requirements directly affect credentialing documentation and referral workflows. A hospitalist or general internist managing a patient post-implant does not satisfy the managing physician requirement under this NCD. Make sure your post-implant care assignments reflect this.
CED Study Criteria — The Coverage Gating Requirement
Every covered IPAPS service must be furnished within the context of a CMS-approved CED study. The study protocol must include only patients meeting the criteria above, use only qualified practitioners, and meet specific data collection and outcomes reporting requirements. If your facility is not currently enrolled in or affiliated with an approved CED study, CMS coverage under NCD 378 is not available—period.
Revenue cycle teams should confirm CED study affiliation before scheduling any IPAPS procedure intended for Medicare billing.
| 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 |
Affected Codes
This policy does not list specific CPT or HCPCS codes. The NCD 378 policy document as published does not enumerate applicable billing codes. Billing teams should monitor the CMS NCD Manual and any associated transmittals for code-level guidance, and watch for contractor-level LCD policies that may map specific codes to this NCD.
When code-level guidance becomes available, PayerPolicy will update this post and alert subscribers.
Why This Policy Matters for Revenue Cycle Teams
The CED requirement is the single biggest claims risk embedded in this policy. Without documented enrollment in a CMS-approved study, claims will lack the foundational coverage basis CMS requires—leading to denials that cannot be corrected with additional clinical documentation alone.
Beyond the CED requirement, the seven-point patient criteria checklist creates audit exposure if documentation is incomplete. Every criterion needs to be explicitly supported in the medical record:
- NYHA class documentation dated within 30 days of implant
- Evidence of HF hospitalization or urgent OP visit within 12 months (or natriuretic peptide lab results within 30 days)
- GDMT medication history spanning at least three months
- ICD/CRT evaluation and implant dates (if applicable)
- Attestation that no major cardiovascular event occurred in the prior three months
- Patient connectivity capability documentation
- Confirmation that the implant is not occurring during an acute HF admission
Each of these is a potential denial trigger if absent.
What Your Billing Team Should Do
| # | Action Item |
|---|---|
| 1 | Confirm CED study participation immediately. Contact your cardiology department and hospital administration before March 12, 2026 to verify whether your facility is affiliated with a CMS-approved IPAPS CED study. If not, identify the pathway to enrollment—or pause IPAPS procedures intended for Medicare billing until enrollment is confirmed. |
| 2 | Build a pre-implant documentation checklist. Create a seven-point checklist mapped directly to the patient criteria in NCD 378. This checklist should be completed and signed before any IPAPS procedure is scheduled, and the supporting documentation should be uploaded to the patient's chart. Include NYHA class assessment date, natriuretic peptide results or hospitalization records, GDMT start date, device evaluation records, and cardiovascular event history. |
| 3 | Audit physician credentialing against CMS requirements. Cross-reference your current list of physicians referring, managing, and implanting IPAPS patients against the specialty and training requirements in section B.2. Flag any gaps and work with your credentialing team to document compliance before the effective date. |
| 4 | Update your admission screening protocol. Add a flag to intake and scheduling workflows that prevents IPAPS implantation from being scheduled or performed during an active acute HF admission. This is an explicit coverage exclusion and a denial risk that can be prevented at the point of scheduling. |
| 5 | Monitor CMS for code-level guidance. Because NCD 378 does not enumerate specific CPT or HCPCS codes, watch for transmittals and MAC-level guidance that will specify how to bill these services. Subscribe to CMS transmittal updates and PayerPolicy alerts to catch this guidance as soon as it publishes. |
