Indirect Measurement of Left Ventricular Filling Pressure (LVFP) — CPB 0704 | AETNA Coverage Update

TL;DR: Aetna, a CVS Health company, modified CPB 0704 covering indirect measurement of left ventricular filling pressure (LVFP), effective November 26, 2025. CPT 0932T and HCPCS C9786 are explicitly non-covered under this policy. Here's what billing teams need to do.

Aetna's update to CPB 0704 draws a hard line on two technologies your cardiology or heart failure program may already be using: the VeriCor® System for arterial waveform-based LVFP measurement, and EchoGo Heart Failure for AI-assisted detection of heart failure with preserved ejection fraction (HFpEF). Both are now explicitly classified as experimental, investigational, or unproven. If your team bills CPT 0932T or HCPCS C9786 against any I50.x heart failure diagnosis code for Aetna members, expect denials. This is a straightforward non-coverage policy — but the codes affected are new enough that many billing teams haven't built the right edits yet.

Quick-Reference Table

Aetna LVFP Coverage Criteria and Medical Necessity Requirements 2025

The Aetna LVFP coverage policy under CPB 0704 is not a nuanced document with a long list of criteria to meet. It's a flat denial policy. There are no covered indications for indirect LVFP measurement through either technology addressed here.

Aetna does not consider indirect measurement of left ventricular filling pressure via computerized calibration of arterial waveform response to the Valsalva maneuver — the method used by the VeriCor® System — to meet medical necessity standards. Similarly, EchoGo Heart Failure, the AI-powered echocardiogram post-processing tool used to detect HFpEF, fails Aetna's medical necessity threshold across all indications.

"All indications" is the phrase to notice. This isn't a narrow exclusion for a specific patient population. Aetna is saying EchoGo Heart Failure doesn't meet medical necessity for any clinical scenario. That's a broad block, and it means there's no documentation pathway that salvages a claim for CPT 0932T or HCPCS C9786 on an Aetna member.

In most cases, prior authorization is irrelevant when a payer classifies a service as experimental or investigational. A prior auth process assumes a service is potentially coverable under certain conditions. When payers treat something as experimental, prior auth approval doesn't change that determination — and the claim typically won't pay regardless. That said, CPB 0704 doesn't specifically address prior authorization, so confirm this with your billing consultant or compliance officer before assuming it applies to your contracts.

The reimbursement exposure is real. CPT 0932T and HCPCS C9786 are relatively new codes, and some practices have begun integrating AI echo analysis tools into their heart failure workflows. If your billing team didn't build Aetna-specific edits when these codes were added to your charge master, claims may have already gone out — and you may have paid claims sitting in your system that Aetna could recoup on audit.

Aetna LVFP Exclusions and Non-Covered Indications

Both technologies addressed in CPB 0704 are experimental and investigational under Aetna's coverage policy. Neither has a covered pathway.

VeriCor® System — Arterial Waveform LVFP Measurement

This device measures left ventricular filling pressure indirectly by analyzing arterial waveform response during the Valsalva maneuver, then applying computerized calibration to estimate LVFP. Aetna's position is that the clinical evidence doesn't support routine use. This classification applies regardless of the patient's heart failure subtype or functional status.

EchoGo Heart Failure — AI Echocardiogram Analysis

EchoGo Heart Failure performs post-processing analysis on standard echocardiogram images. It uses augmentative AI analysis to detect heart failure with preserved ejection fraction. CPT 0932T covers noninvasive detection of heart failure derived from augmentative analysis of an echocardiogram. HCPCS C9786 covers echocardiography image post-processing for computer-aided detection of heart failure with preserved ejection fraction.

Aetna excludes both codes from coverage for any indication. The policy language says "all other indications" — meaning even if a future clinical use case emerges, Aetna's current position is that EchoGo Heart Failure doesn't meet their evidence threshold anywhere in the clinical spectrum.

This is a pattern worth watching. Aetna has been methodical about classifying AI-assisted diagnostic tools as experimental until the clinical validation literature catches up. You've seen a similar posture with other AI-assisted diagnostic tools — CPB 0704 fits that same mold. This reflects analyst commentary on broader payer trends, not language sourced from this specific policy.

CPT, HCPCS, and ICD-10 Codes for LVFP Measurement Under CPB 0704

Not Covered / Experimental CPT and HCPCS Codes

These codes are explicitly non-covered under Aetna's CPB 0704 coverage policy. Claims submitted with these codes for Aetna members will result in claim denial.

Key ICD-10-CM Diagnosis Codes Referenced in CPB 0704

These heart failure diagnosis codes appear in the policy. Any of them paired with CPT 0932T or HCPCS C9786 on an Aetna claim will trigger denial based on the non-covered service designation — not the diagnosis code itself. The I50.x codes aren't the problem; the procedure codes are.

Note: The ICD-10 descriptions above reflect source policy data. The full subcategory descriptors for I50.2 through I50.4 include acute, chronic, and acute-on-chronic variants. Your encoder will map the full fourth and fifth character codes correctly — but all of them fall under the same denial exposure when paired with CPT 0932T or C9786 on an Aetna claim.
