Cigna modified MM 0355 for liver and liver-kidney transplantation, effective October 16, 2025. Here's what billing teams need to know before claims go out.
Cigna Healthcare updated its coverage policy for liver transplantation and simultaneous liver-kidney (SLK) transplantation under policy code MM 0355. This revision affects CPT codes 47133, 47135, 47140, 47141, 47142, 47143, 47144, 47145, 47146, and 47147, along with HCPCS code S2152. If your facility or transplant program bills Cigna for these procedures, audit your charge capture and documentation workflows before October 16, 2025.

Cigna Liver Transplant Coverage Criteria and Medical Necessity Requirements 2025
The Cigna liver transplant coverage policy under MM 0355 covers both cadaveric and living donor liver transplantation. Coverage applies to CPT 47135 (orthotopic liver allotransplantation, partial or whole, cadaveric or living donor, any age) when medical necessity criteria in the applicable coverage position are met.
Donor hepatectomy procedures are also covered under this policy when criteria are satisfied. That includes CPT 47133 for cadaveric donor hepatectomy with cold preservation, and CPT 47140, 47141, and 47142 for living donor hepatectomy — left lateral segment, total left lobectomy, and total right lobectomy, respectively. Each of these has its own clinical threshold. Don't assume that coverage for one automatically extends to the others.
Backbench preparation and reconstruction codes are explicitly listed as medically necessary when criteria are met. CPT 47143, 47144, and 47145 cover standard backbench preparation of cadaveric whole liver grafts before allotransplantation. CPT 47146 and 47147 cover backbench reconstruction — venous and arterial, respectively — for both cadaveric and living donor grafts.
HCPCS code S2152 covers solid organ transplantation for deceased or living donor cases. This code is often used by facilities to capture the global transplant service. Confirm with your billing consultant that your facility's use of S2152 aligns with Cigna's current coverage position under MM 0355.
Prior authorization is standard for transplant procedures under most commercial payer policies, and Cigna's approach to transplant coverage is no different. Confirm prior authorization requirements with your Cigna provider representative before the effective date of October 16, 2025. A missing or misaligned prior auth is the fastest path to a claim denial on high-dollar transplant cases.
Cigna Omnibus Reimbursement Policy R24 governs donor organ procurement and transport reimbursement. This is separate from MM 0355 but directly connected — if your team bills for organ procurement alongside the transplant CPT codes, you need to cross-reference both policies. Reimbursement for procurement and transport does not flow through MM 0355 alone.

Cigna Liver Transplant Billing Guidelines and Action Items 2025
These are the steps your billing team should take before October 16, 2025.
| # | Action Item |
|---|---|
| 1 | Audit your charge capture for all 11 affected codes. Pull every claim in your queue that includes CPT 47133, 47135, 47140, 47141, 47142, 47143, 47144, 47145, 47146, 47147, or HCPCS S2152 billed to Cigna. Confirm each maps to the correct clinical scenario — cadaveric vs. living donor, partial vs. whole, standard preparation vs. reconstruction. |
| 2 | Verify prior authorization status on pending transplant cases. Transplant billing without a confirmed prior auth is a near-guaranteed claim denial for high-dollar procedures. Contact your Cigna provider representative now and document auth numbers in your system before October 16, 2025. |
| 3 | Cross-reference Cigna Omnibus Reimbursement Policy R24 for procurement and transport billing. MM 0355 does not govern organ procurement and transport reimbursement. If your team bills for procurement separately alongside the transplant procedure codes, pull R24 and confirm the current reimbursement rules apply correctly to your claim structure. |
| 4 | Update your medical necessity documentation templates. Every code in this policy is covered only "when criteria in the applicable coverage position are met." That language is not a formality — it means Cigna will review documentation on pre-cert and post-pay audit. Make sure your operative reports, clinical notes, and transplant evaluation records clearly address the specific criteria for each code you bill. |
| 5 | Confirm SLK billing protocols with your nephrology and transplant surgery teams. Simultaneous liver-kidney transplantation adds coding complexity. The liver transplant procedure maps to CPT 47135 and S2152 under MM 0355, but the kidney component requires separate coding. Make sure your team isn't bundling the two incorrectly or missing reimbursement by under-coding the kidney side. |
| 6 | Loop in your compliance officer if you're unsure how the MM 0355 modifications affect your specific case mix. Transplant billing carries significant financial exposure per case. If the updated criteria create ambiguity for any procedure type your program performs, get your compliance officer involved before the effective date — not after a denial lands. |

Key ICD-10-CM Diagnosis Codes
