TL;DR: Cigna Healthcare modified MM 0574, its cardiac omnibus coverage policy, effective February 14, 2026. Every cardiac device and procedure covered under this policy — spanning CPT codes 0266T through 0981T and HCPCS codes C1824, C1825, C2624, and G0555 — carries an Experimental/Investigational/Unproven designation. Here's what billing teams need to know.
Cigna Healthcare updated MM 0574, the Cigna cardiac omnibus coverage policy, on February 14, 2026. This policy governs a broad set of advanced cardiac devices — including baroreflex activation therapy, cardiac contractility modulation systems, and wireless hemodynamic pressure sensors. If your practice or facility bills any of these services to Cigna, expect denials. Every code in this policy sits in the Experimental/Investigational/Unproven bucket.

Cigna Cardiac Device Coverage Criteria and Medical Necessity Requirements 2026
The core position in the MM 0574 Cigna cardiac omnibus coverage policy is straightforward: Cigna classifies all devices and procedures under MM 0574 as Experimental/Investigational/Unproven. The policy provides no covered indications. That applies across the board — baroreflex activation, cardiac contractility modulation, left atrial pressure sensors, pulmonary artery pressure sensors, and inferior vena cava sensors.
That classification matters for your billing team because it triggers automatic claim denial regardless of diagnosis, patient severity, or physician documentation. There is no clinical pathway that unlocks coverage under this policy. You cannot overcome an Experimental/Investigational designation with a stronger prior authorization request or more detailed chart notes.
The source data does not describe what changed from the prior version. Review the full policy diff for version comparison.
The source policy does not address prior authorization. Consult your Cigna provider agreement for applicable PA requirements. Document that process internally, and redirect administrative time accordingly.
For billing purposes, the policy is the policy. Reimbursement under Cigna for these services is not available under MM 0574.
Cigna Cardiac Omnibus Exclusions and Non-Covered Indications
Every device and procedure in MM 0574 carries the same designation: Experimental/Investigational/Unproven. There are no covered indications, no coverage tiers, and no exceptions listed in this policy.
The devices addressed include:
| # | Excluded Procedure |
|---|---|
| 1 | Carotid sinus baroreflex activation (BAROSTIM™ NEO® System) — billed under CPT 0266T, 0268T, and 64654, and HCPCS C1825 |
| 2 | Cardiac contractility modulation (CCM) systems — billed under CPT 0408T, 0915T, 0916T, 0917T, 0918T, 0930T, and 0931T, and HCPCS C1824 |
| 3 | CCM-defibrillation systems — also captured under 0915T–0931T |
| 4 | Left atrial pressure sensors (HeartPOD, Promote LAP, V-LAP systems) — billed under CPT 0933T |
| 5 | Pulmonary artery pressure sensors (CardioMEMS™ HF, Cordella™) — billed under CPT 33289 and HCPCS C2624, with patient electronics replacement under G0555 |
| 6 | Inferior vena cava sensors — billed under CPT 0981T |
| 7 | Associated diagnostic and procedural codes — CPT 36013, 37252, 37253, 75825, 76000, 93451, 93453, 93456, 93460, 93461, 93566, 93593, 93594, 93596, and 93597 are all grouped under the same experimental designation when used in connection with these implantations |
The breadth of codes here is the real issue. It's not just the implantation codes — the associated catheterization, fluoroscopy, hemodynamic assessment, and pressure measurement codes (the 93xxx series and the 36xxx/75xxx series) are also swept in. If you bill a hemodynamic study in conjunction with a pulmonary artery pressure sensor implant, the companion codes go down with it.

Cigna Cardiac Omnibus Billing Guidelines and Action Items 2026
The billing implications here are direct. These aren't gray-area codes where documentation might tip a denial to an approval. Every code in MM 0574 is categorically excluded. Your action items should focus on protection — stopping write-offs, managing patient financial counseling, and documenting the denial rationale for appeals or alternative payer pursuit.
| # | Action Item |
|---|---|
| 1 | Audit all pending Cigna claims for MM 0574 codes before February 14, 2026. Pull claims containing CPT 0266T, 0268T, 0408T, 0915T–0918T, 0930T, 0931T, 0933T, 0981T, 33289, and 64654, plus HCPCS C1824, C1825, C2624, and G0555. Flag any that haven't been adjudicated and prepare for denial. |
| 2 | Update your charge capture to tag all MM 0574 codes as non-reimbursable under Cigna. Your practice management system should alert coders at the point of charge entry when a Cigna patient receives one of these services. That prevents a claim from ever going out the door without a denial expectation attached. |
| 3 | Review any companion codes billed alongside these implantations. The 93xxx hemodynamic series (93451, 93453, 93456, 93460, 93461, 93566, 93593, 93594, 93596, 93597) and the vascular access codes (36013, 37252, 37253, 75825, 76000) are all flagged experimental under MM 0574. Don't assume companion codes will survive a denial on the primary implant code. |
| 4 | Counsel patients before the procedure, not after. If a Cigna member is scheduled for a CardioMEMS implant or a BAROSTIM procedure, your team needs to deliver a financial counseling conversation before the procedure date. Use an Advance Beneficiary Notice equivalent for commercial plans — an Advance Coverage Notice — that documents the patient's acknowledgment that Cigna will not cover this service. |
| 5 | Check for secondary coverage before filing. Some patients with Cigna as their primary insurer carry secondary commercial coverage or Medicare. Medicare has a different coverage position on several of these devices. Don't let a Cigna denial on the primary close your billing window if secondary coverage exists. |
| 6 | If your team sees high volume of these codes and you're uncertain how this interacts with your employer group contracts, talk to your compliance officer. Some self-funded Cigna plans use modified benefit designs that deviate from standard Cigna billing guidelines. Your compliance officer or billing consultant can help you identify which of your Cigna lives are fully insured versus self-funded. |
| 7 | Document denial reasons meticulously for potential appeals or peer-to-peer requests. Even where Cigna's coverage policy is clear, physicians may request a peer-to-peer review for individual cases. That process requires well-organized clinical documentation. Build that documentation habit now, before the February 14, 2026 effective date, so your team isn't scrambling. |
| 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 |
