Coverage Summary

Trek Health ingests and normalizes Transparency in Coverage data and payer policy updates to give provider organizations a clear view of how commercial reimbursement behaves across markets, payers, and services. Our platform transforms raw payer disclosures into structured intelligence that supports contract evaluation, payer negotiations, and service line strategy. By combining market benchmarks with ongoing policy visibility, Trek helps teams identify variability, risk, and opportunity in commercial reimbursement. The result is faster insight, stronger negotiating positions, and more informed financial decisions.

Status: CURRENT. Policy subject: Pancreatic islet cell transplantation (autologous). EmblemHealth considers autologous pancreatic islet cell transplantation covered with criteria for members with chronic pancreatitis who meet the specified medical necessity criteria. Autologous islet transplantation is covered when the patient meets the required criteria (severe pain refractory to medical management and transplantation performed adjunctive to total/near-total pancreatectomy). Allogeneic and xenotransplantation approaches are not covered under this indication and are addressed as investigational/not medically necessary in the policy background and limitations.

ALL of the following

Severe pain refractory to medical management.
Transplantation is adjunctive to total/near-total pancreatectomy.

Not Medically Necessary / Limitations

Documentation Required

Clinical documentation required for review

The treating physician or primary care provider must submit to EmblemHealth the clinical evidence that the member meets the criteria for the treatment or surgical procedure. Without this documentation and information, EmblemHealth will not be able to properly review the request — preauthorization or post-payment review.

Document that the member has severe pain refractory to medical management and that transplantation is adjunctive to total/near-total pancreatectomy.

Note

Pancreas transplant referrals

For whole organ (pancreas) transplant to treat Type 1 diabetes, members and providers must call the EmblemHealth Transplant Program for case management services at 1-800-447-0768.

Background & Definitions

Background: Autologous islet transplantation is performed as an adjunct to total or near-total pancreatectomy to salvage and transplant the patient's own beta cells into the portal vein of the liver to help prevent post-pancreatectomy diabetes. The procedure involves isolating islet cells from the individual's resected pancreatic specimen, creating a suspension with plasma, and infusing that suspension into the portal vein so the cells function as a free graft. By contrast, allogeneic islet transplantation (using donor human cells) and xenotransplantation (using porcine cells) require lifelong immunosuppression to prevent graft rejection and recurrence of autoimmune disease and are considered investigational / not medically necessary for treatment of Type 1 diabetes due to insufficient evidence.

Term	Definition
Autologous islet transplantation	Technique performed as an adjunct to total/near-total pancreatectomy using islet cells isolated from the individual's resected pancreas and infused into the portal vein to function as a free graft.
Allogeneic islet transplantation	Islet transplantation using donor (non-recipient) human cells requiring lifelong immunosuppression.
Xenotransplantation	Islet transplantation utilizing porcine cells.

Evidence & Guidance

Evidence and references: The policy references multiple guideline and registry sources, including MCG care guidelines, American Diabetes Association position statements, National Institute for Health and Clinical Excellence (NICE) guidance, and the CMS National Coverage Determination for islet cell transplantation in the context of a clinical trial.
