Cigna modified MM 0501 covering transcatheter heart valve procedures, effective December 16, 2025. Here's what billing teams need to know before that date.
Cigna Healthcare updated its transcatheter heart valve coverage policy under MM 0501 to address aortic and pulmonary valve replacement, percutaneous mitral valve repair, and tricuspid valve repair or replacement. The update draws a clear line between what Cigna considers medically necessary and what it classifies as experimental — and that line runs directly through several high-dollar CPT codes your team may already be billing. The primary codes affected include 33361 through 33366 for TAVR/TAVI, 33418 for percutaneous mitral valve repair, 0483T for transcatheter mitral valve implantation, and 0484T, 0569T, and 0646T, which remain in experimental territory.

Cigna Transcatheter Heart Valve Coverage Criteria and Medical Necessity Requirements 2025
The Cigna transcatheter heart valve coverage policy under MM 0501 covers two distinct clinical pathways: transcatheter aortic valve replacement (TAVR/TAVI) and percutaneous mitral valve repair. Each has its own medical necessity criteria, and failing to document against those criteria is the fastest way to trigger a claim denial.
For TAVR/TAVI, Cigna considers CPT codes 33361, 33362, 33363, 33364, 33365, and 33366 medically necessary when patients meet defined selection criteria. These six codes cover every approved access route — percutaneous femoral, open femoral, open axillary, open iliac, transaortic, and transapical. The access approach does not change the coverage threshold. Medical necessity does.
For percutaneous mitral valve repair, CPT 33418 is considered medically necessary when the applicable criteria are met. CPT 0483T — transcatheter mitral valve implantation or replacement via percutaneous approach — also falls under the medically necessary category, but with its own criteria. Do not conflate repair (33418) with replacement (0483T) in your documentation or prior authorization requests. Cigna treats them differently, and your supporting documentation should too.
Prior authorization almost certainly applies to these procedures given their complexity and dollar value. Confirm with Cigna directly for each patient and plan type — commercial, Medicare Advantage, and managed Medicaid may have different prior auth workflows under MM 0501. Missing prior authorization on a TAVR claim is not a correctable error after the fact.
Reimbursement for these procedures is substantial, which is exactly why Cigna scrutinizes them closely. Underdocumented claims for 33361–33366 or 33418 will face denial or downcoding. Your clinical documentation should map directly to the medical necessity criteria in MM 0501 before the claim ever leaves your system.
Cigna Transcatheter Heart Valve Exclusions and Non-Covered Indications
Three codes remain firmly in experimental and investigational status under this coverage policy. Cigna will not reimburse claims for these procedures under MM 0501, and no amount of additional documentation changes that classification.
CPT 0484T — Transcatheter mitral valve implantation or replacement with prosthetic valve via transthoracic exposure — is considered experimental and investigational. This is a different access approach from 0483T, and the transthoracic route does not currently meet Cigna's coverage threshold.
CPT 0569T — Transcatheter tricuspid valve repair, percutaneous approach, initial prosthesis — is experimental. Cigna does not cover percutaneous tricuspid valve repair under MM 0501.
CPT 0646T — Transcatheter tricuspid valve implantation or replacement with prosthetic valve, percutaneous approach — is also experimental. Transcatheter tricuspid interventions, whether repair or replacement, sit outside Cigna's covered indications at this time.
The real risk here is upcoding or miscoding between covered and non-covered procedures. A transcatheter mitral valve repair (33418, covered) and a transcatheter mitral valve replacement via transthoracic access (0484T, experimental) are not interchangeable. If your clinical team performs a procedure that maps to an experimental code, bill that code — and counsel the facility on the financial exposure before the case.
There is also a data artifact in the policy code table worth flagging. A row referencing "20549 low surgical risk patients" appears in the experimental group with no valid CPT code attached. This looks like a documentation error in the source policy — likely a fragment of clinical study data embedded in the wrong field. Do not bill this as a code. Flag it with your billing consultant if it surfaces in your charge capture workflow.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| TAVR/TAVI — percutaneous femoral artery approach | Covered (criteria required) | 33361 | Medical necessity criteria must be met |
| TAVR/TAVI — open femoral artery approach | Covered (criteria required) | 33362 | Medical necessity criteria must be met |
| TAVR/TAVI — open axillary artery approach | Covered (criteria required) | 33363 | Medical necessity criteria must be met |
| TAVR/TAVI — open iliac artery approach | Covered (criteria required) | 33364 | Medical necessity criteria must be met |
| TAVR/TAVI — transaortic approach | Covered (criteria required) | 33365 | Medical necessity criteria must be met |
| TAVR/TAVI — transapical exposure | Covered (criteria required) | 33366 | Medical necessity criteria must be met |
| Percutaneous mitral valve repair | Covered (criteria required) | 33418 | Prior auth likely required; distinct from replacement |
| Transcatheter mitral valve implantation/replacement — percutaneous approach | Covered (criteria required) | 0483T | Separate criteria from 33418; document distinctly |
| Transcatheter mitral valve implantation/replacement — transthoracic exposure | Experimental/Investigational | 0484T | Not covered under MM 0501 |
| Transcatheter tricuspid valve repair — percutaneous approach | Experimental/Investigational | 0569T | Not covered under MM 0501 |

Cigna Transcatheter Heart Valve Billing Guidelines and Action Items 2025
The effective date of December 16, 2025 is your deadline. Work backward from it.
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for CPT 33361–33366 now. Pull every TAVR/TAVI claim from the past 90 days billed to Cigna. Confirm the medical necessity documentation in each case file maps to MM 0501 criteria. Gaps now become denials after December 16, 2025. |
| 2 | Separate your mitral valve repair and replacement workflows. CPT 33418 (repair) and 0483T (replacement, percutaneous) are both covered — but they require distinct documentation and likely distinct prior authorization pathways. Merge them in your workflow and you will generate denials. |
| 3 | Flag 0484T, 0569T, and 0646T in your charge capture system as non-covered under Cigna. Add an edit or alert that stops these codes from routing to Cigna claims without a compliance review. These are experimental under MM 0501. Billing them risks both claim denial and potential overpayment liability. |
| 4 | Confirm prior authorization requirements with Cigna for each plan type. Call your Cigna provider relations contact or check the portal before the effective date. Commercial plans, Medicare Advantage products, and managed Medicaid contracts may have different prior auth rules under MM 0501. Document the confirmation. |
| 5 | Brief your structural heart team on the covered-versus-experimental split. Your interventional cardiologists and cardiac surgeons need to know that tricuspid valve procedures — both repair (0569T) and replacement (0646T) — are not covered. If your program is planning cases, patients need financial counseling before scheduling. Surprises after a procedure are a collections problem, not just a billing problem. |
| 6 | Loop in your compliance officer on the anomalous code row in the policy. The entry referencing "20549 low surgical risk patients" in the experimental group does not correspond to a valid CPT code. If it surfaces in your billing system or payer communications, you need a documented response protocol. Your compliance officer should weigh in on how to handle it if Cigna references it in a denial or audit. |
If you are unsure how MM 0501 applies to your specific payer mix — especially if you have significant Cigna Medicare Advantage volume — talk to your billing consultant before December 16, 2025.
