TL;DR: Aetna modified CPB 0832, classifying implantable left atrial hemodynamic monitors as experimental, investigational, or unproven — meaning CPT 0933T and 0934T are not covered for any heart failure indication, effective December 10, 2025.
If your cardiology or heart failure program has been billing — or planning to bill — for left atrial pressure monitoring devices like the HeartPOD, Promote LAP, or V-LAP systems, this policy shuts that door. Aetna updated its implantable left atrial hemodynamic monitor coverage policy under CPB 0832, and the position is unambiguous: no coverage, no exceptions.

Aetna Implantable Left Atrial Hemodynamic Monitor Coverage Criteria and Medical Necessity Requirements 2025
Here's the short version of Aetna's implantable left atrial hemodynamic monitor coverage policy: there are no covered indications. The policy doesn't carve out specific patient populations, disease stages, or clinical scenarios where reimbursement applies. Aetna's position is that the evidence base isn't there — full stop.
CPT 0933T covers transcatheter implantation of a wireless left atrial pressure sensor for long-term left atrial pressure monitoring. CPT 0934T covers remote monitoring of that sensor for up to 30 days, including data analysis. Both codes fall under Aetna's "not covered for indications listed in the CPB" designation.
Medical necessity, as Aetna defines it in CPB 0832, simply cannot be established for these devices. The policy cites insufficient evidence in peer-reviewed literature. Until that evidence threshold changes, no amount of clinical documentation will convert these claims to paid status.
If you have Aetna patients with active heart failure management plans that include left atrial pressure monitoring, talk to your compliance officer before December 10, 2025. Submitting 0933T or 0934T on Aetna claims after the effective date is a clean path to claim denial and potential recoupment exposure.
Aetna Implantable Left Atrial Hemodynamic Monitor Exclusions and Non-Covered Indications
CPB 0832 names three specific devices under the experimental, investigational, or unproven designation:
| # | Excluded Procedure |
|---|---|
| 1 | HeartPOD System |
| 2 | Promote LAP System |
| 3 | V-LAP System |
These are the current market entrants for implantable left atrial hemodynamic monitoring. Aetna didn't exclude one device and cover another — the entire device category is excluded. If a new system enters the market under a different brand name, expect the same non-coverage position to apply until Aetna revises CPB 0832.
The diagnosis codes attached to this policy span the full I50 heart failure category — I50.1 through I50.9. That's every heart failure subtype: systolic, diastolic, combined, right heart failure, biventricular, and unspecified. There's no heart failure diagnosis that creates a coverage exception. The coverage policy doesn't discriminate by ejection fraction, NYHA class, or prior hospitalization history.
This is a broader exclusion than some practices may realize. Heart failure programs managing high-risk, frequently hospitalized patients might assume Aetna would recognize clinical value in continuous hemodynamic monitoring. CPB 0832 says otherwise, and the evidence standard Aetna applies here is the same it uses for other implantable monitoring technologies it considers premature for routine coverage.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Heart failure — all subcategories (I50.1–I50.9) | Not Covered | 0933T, 0934T | Aetna considers all implantable LA hemodynamic monitoring experimental/investigational |
| Transcatheter implantation of wireless LA pressure sensor | Not Covered | 0933T | No covered indications under CPB 0832 |
| Remote monitoring of wireless LA pressure sensor (up to 30 days) | Not Covered | 0934T | No covered indications under CPB 0832 |
| HeartPOD System | Not Covered | 0933T, 0934T | Named explicitly in CPB 0832 as experimental |
| Promote LAP System | Not Covered | 0933T, 0934T | Named explicitly in CPB 0832 as experimental |
| V-LAP System | Not Covered | 0933T, 0934T | Named explicitly in CPB 0832 as experimental |
Aetna Implantable Left Atrial Hemodynamic Monitor Billing Guidelines and Action Items 2025
The action items here are straightforward. This isn't a policy with nuance to interpret — it's a non-coverage ruling. Your response should be equally direct.
| # | Action Item |
|---|---|
| 1 | Remove CPT 0933T and 0934T from your Aetna charge capture before December 10, 2025. If these codes are mapped in your charge description master (CDM) for Aetna payer contracts, flag them as non-covered. Don't wait to see a denial — build the stop upstream. |
| 2 | Audit any claims already submitted to Aetna with 0933T or 0934T. If you billed these codes before the effective date, check your claim status. Understand whether Aetna's prior policy position supported any payment, and assess your recoupment exposure if those claims are revisited under CPB 0832's modified language. |
| 3 | Update your Aetna prior authorization workflow to exclude these procedures. CPB 0832 does not mention prior authorization as a pathway to coverage. Based on the blanket non-coverage designation, submitting PA requests for 0933T or 0934T is unlikely to result in approval — but confirm this with your Aetna provider relations contact or your compliance officer before assuming PA is completely off the table. Submitting those requests wastes time and may create false expectation with your clinical team. |
| 4 | Document financial counseling conversations for any patient already scheduled. If a patient is scheduled for implantation of a HeartPOD, Promote LAP, or V-LAP system and carries Aetna coverage, they need to know before the procedure that Aetna will not pay. Your ABN or equivalent financial liability notice process should be initiated immediately. |
| 5 | Brief your heart failure and interventional cardiology teams on this change. Physicians ordering or performing these procedures need to understand the reimbursement picture for Aetna members. A procedure with no payer coverage isn't just a billing problem — it's a patient financial counseling obligation. Get your medical director or department chief aligned before December 10, 2025. |
| 6 | Check your other payers' positions on 0933T and 0934T. Just because Aetna excludes left atrial hemodynamic monitoring billing doesn't mean every payer does. Review your payer mix. Some commercial plans and certain Blue Cross plans may have different positions. CMS has not established a national coverage determination for these codes, so Medicare coverage defaults to local coverage determination (LCD) policy — check with your Medicare Administrative Contractor for regional guidance. |
If your program has significant Aetna volume and was building a service line around left atrial pressure monitoring, this policy makes that financially untenable for now. Talk to your compliance officer and billing consultant about how to communicate this to your clinical stakeholders.

Key ICD-10-CM Diagnosis Codes Referenced in CPB 0832
These codes represent the heart failure diagnoses associated with this policy. All nine are non-covered when paired with 0933T or 0934T under Aetna CPB 0832.
| Code | Description |
|---|---|
| I50.1 | Heart failure |
| I50.2 | Heart failure |
| I50.3 | Heart failure |
| I50.4 | Heart failure |
| I50.5 | Heart failure |
| I50.6 | Heart failure |
