TL;DR: Cigna Healthcare modified MM 0533, its stem cell transplantation coverage policy for blood cancers, effective December 16, 2025. Here's what billing teams need to do before claims start moving through the system.
Cigna Healthcare updated Coverage Policy MM 0533, which governs hematopoietic stem cell transplantation (HSCT) for leukemias, lymphomas, and myeloma. This policy covers 17 CPT codes — including CPT 38240 and 38241 for allogeneic and autologous transplantation — plus three HCPCS codes (S2140, S2142, and S2150) for cord blood and peripheral stem cell procedures. If your team bills for bone marrow harvesting, progenitor cell preparation, or transplant services under any Cigna commercial or managed care plan, this change is live and you need to review your workflows now.

Cigna Stem Cell Transplantation Coverage Criteria and Medical Necessity Requirements 2025
The Cigna stem cell transplantation coverage policy under MM 0533 covers HSCT for blood cancers — specifically leukemias, lymphomas, and myeloma — when the procedure meets defined medical necessity criteria. Every code in this policy, from CPT 38204 (donor search and cell acquisition management) through CPT 38242 (allogeneic lymphocyte infusions), carries the same qualifying language: considered medically necessary when criteria in the applicable coverage position are met.
That phrase does a lot of work. It means no code in this policy is automatically payable. Each claim requires documentation showing the patient's diagnosis and condition meet Cigna's specific coverage position for that transplant type.
For autologous transplants, CPT 38206 (blood-derived progenitor cell harvesting, autologous) and CPT 38241 (autologous transplantation) are the anchors. For allogeneic procedures, CPT 38205 (allogeneic harvesting), CPT 38230 (allogeneic bone marrow harvesting), and CPT 38240 (allogeneic transplantation per donor) are the core billing codes. Cord blood procedures — S2140 for harvesting and S2142 for the transplant itself — fall under the same medical necessity standard.
Prior authorization is not optional on these services. HSCT for blood cancers is among the highest-cost, highest-scrutiny categories in oncology billing. Cigna requires prior auth on transplant services, and documentation gaps at authorization stage will create claim denial exposure downstream. Build your auth request around the specific blood cancer diagnosis, the transplant type, and the evidence base supporting the procedure — not a generic transplant request.
The reimbursement stakes here are significant. HSCT procedures routinely generate five- and six-figure claims. A single denial on CPT 38240 or 38241 is not a nuisance — it's a revenue cycle event. Get the medical necessity documentation right before December 16, 2025, not after.
Coverage Indications at a Glance
The policy does not list individual diagnosis-level exclusions in the summary data available. All 17 CPT codes and three HCPCS codes carry a single coverage designation: medically necessary when criteria are met. The table below maps procedure categories to their applicable codes and billing considerations.
| Indication / Procedure Category | Status | Relevant Codes | Notes |
|---|---|---|---|
| Donor search and cell acquisition (allogeneic) | Covered when criteria met | CPT 38204 | Requires documented allogeneic transplant plan |
| Blood-derived progenitor cell harvesting — allogeneic | Covered when criteria met | CPT 38205 | Prior auth required |
| Blood-derived progenitor cell harvesting — autologous | Covered when criteria met | CPT 38206 | Prior auth required |
| Progenitor cell cryopreservation and storage | Covered when criteria met | CPT 38207 | Must be linked to covered transplant plan |
| Thawing of previously frozen harvest (with anticoagulant) | Covered when criteria met | CPT 38208 | Typically billed with transplant episode |
| Thawing of previously frozen harvest (without anticoagulant) | Covered when criteria met | CPT 38209 | Typically billed with transplant episode |
| T-cell depletion within harvest | Covered when criteria met | CPT 38210 | Document clinical rationale for depletion |
| Tumor cell depletion | Covered when criteria met | CPT 38211 | Document clinical rationale |
| Red blood cell removal from harvest | Covered when criteria met | CPT 38212 | Preparation step — tie to primary transplant auth |
| Platelet depletion from harvest | Covered when criteria met | CPT 38213 | Preparation step |
| Plasma (volume) depletion from harvest | Covered when criteria met | CPT 38214 | Preparation step |
| Cell concentration in plasma | Covered when criteria met | CPT 38215 | Preparation step |
| Bone marrow harvesting — allogeneic | Covered when criteria met | CPT 38230 | Prior auth required; confirm donor eligibility documentation |
| Bone marrow harvesting — autologous | Covered when criteria met | CPT 38232 | Prior auth required |
| Allogeneic transplantation | Covered when criteria met | CPT 38240 | Highest-value code in this policy — documentation must be airtight |
| Autologous transplantation | Covered when criteria met | CPT 38241 | High-value; verify diagnosis and staging documentation |
| Allogeneic lymphocyte infusions | Covered when criteria met | CPT 38242 | Often used post-transplant for relapse management |
| Cord blood harvesting — allogeneic | Covered when criteria met | HCPCS S2140 | Verify plan includes cord blood coverage |
| Cord blood-derived stem cell transplant — allogeneic | Covered when criteria met | HCPCS S2142 | Not all Cigna plans cover cord blood; confirm benefit |
| Bone marrow or blood-derived stem cells (allogeneic or autologous) | Covered when criteria met | HCPCS S2150 | Broad harvest/harvest-and-transplant code; confirm appropriate use |
One flag on S2142 and S2150: cord blood and peripheral stem cell HCPCS codes are not uniformly covered across all Cigna plan types. Confirm the specific plan's benefit structure before assuming these codes will clear.
Cigna Stem Cell Transplantation Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your prior authorization workflow before December 16, 2025. Every HSCT case billed under MM 0533 needs a clean prior auth tied to the specific transplant type and blood cancer diagnosis. Review any auths already in process — confirm they reflect the updated coverage position criteria, not the prior version. |
| 2 | Verify CPT 38240 and 38241 documentation meets the updated medical necessity threshold. These are your two highest-value transplant codes. A claim denial on either one triggers a lengthy appeals process. Your clinical team must document the specific leukemia, lymphoma, or myeloma diagnosis, the disease stage, prior treatment history, and the clinical rationale for transplant over alternative therapy. |
| 3 | Map your preparation codes (CPT 38207–38215) to the primary transplant authorization. Cryopreservation, thawing, cell depletion, and volume reduction codes all require the same underlying coverage justification as the transplant itself. Cigna will scrutinize these codes if they're submitted without a clear link to an authorized transplant episode. |
| 4 | Confirm cord blood codes (S2140, S2142) against the patient's specific Cigna plan. HCPCS S-codes are not uniformly covered across all Cigna commercial products. Pull the plan's benefit language before submitting. If the plan excludes cord blood and you bill S2142, that's a denial you should have caught before claim submission. |
| 5 | Update your charge capture for CPT 38204 on allogeneic cases. Donor search and cell acquisition (CPT 38204) is often missed or bundled incorrectly. It's a separately billable service with its own medical necessity requirement. Make sure your charge capture logic flags this code for allogeneic transplant cases. |
| 6 | Train your billing team on the distinction between allogeneic and autologous codes. CPT 38205 vs. 38206 for harvesting, 38230 vs. 38232 for bone marrow, and 38240 vs. 38241 for the transplant — these are not interchangeable. A wrong transplant type on the claim creates a medical necessity mismatch with the auth and triggers denial. |
| 7 | If your program bills a high volume of HSCT cases, loop in your compliance officer now. MM 0533 modifications affect medical necessity criteria for some of the most expensive procedures in oncology. Before the December 16, 2025 effective date, your compliance officer should review the updated coverage position in full and confirm your documentation standards align. Don't wait for your first denial to find out there's a gap. |
