Allogeneic Pancreas Transplant
Policy Number: MP-386
Latest Review Date: August 2024
Category: Surgery
POLICY:
Pancreas transplant after a prior kidney transplant may be considered medically necessary in individuals with insulin dependent diabetes.
A combined pancreas-kidney transplant may be considered medically necessary in insulin dependent diabetic individuals with uremia.
Pancreas transplant alone may be considered medically necessary in individuals with severely disabling and potentially life-threatening complications due to hypoglycemia unawareness and labile insulin dependent diabetes that persists despite optimal medical management.
Pancreas retransplant after a failed primary pancreas transplant may be considered medically necessary in individuals who meet criteria for pancreas transplantation.
Pancreas transplant is considered investigational in all other situations.
POLICY GUIDELINES:
General Criteria
Potential contraindications for solid organ transplant that are subject to the judgment of the transplant center include the following:
- Known current malignancy, including metastatic cancer;
- Recent malignancy with a high incidence of recurrence;
- History of cancer with a moderate risk of recurrence;
- Systemic disease that could be exacerbated by immunosuppression;
- Untreated systemic infection making immunosuppression unsafe, including chronic infection;
- Other irreversible end-stage disease not attributed to kidney disease;
- Psychosocial conditions or chemical dependency affecting ability to adhere to therapy.
Pancreas-Specific Criteria
Candidates for pancreas transplant alone should also meet one of the following severity of illness criteria:
- Documented severe hypoglycemia unawareness as evidenced by chart notes or emergency department visits or
- Documented potentially life-threatening labile diabetes, as evidenced by chart notes or hospitalization for diabetic ketoacidosis.
Additionally, most pancreas transplant individuals will have type 1 diabetes. In 2022, individuals with type 2 diabetes accounted for 22.4% of all pancreas transplants, according to data from the Organ Procurement and Transplantation Network and the Scientific Registry of Transplant Recipients.
Multiple Transplants
Although there are no standard guidelines for multiple pancreas transplants, the following information should be considered:
- If there is early graft loss resulting from technical factors (e.g., venous thrombosis), a retransplant may generally be performed without substantial additional risk.
- Long-term graft losses may result from chronic rejection, which is associated with increased risk of infection following long-term immunosuppression, and sensitization, which increases the difficulty of finding a negative cross-match. Some transplant centers may wait to allow reconstitution of the immune system before initiating retransplant with an augmented immunosuppression protocol.
DESCRIPTION OF PROCEDURE OR SERVICE:
Solid organ transplantation offers a treatment option for individuals with different types of end-stage organ failure that can be lifesaving or provide significant improvements to an individual’s quality of life. Many advances have been made in the last several decades to reduce perioperative complications. Available data supports improvement in long-term survival as well as improved quality of life particularly for liver, kidney, pancreas, heart, and lung transplants. Allograft rejection remains a key early and late complication risk for any organ transplantation. Transplant recipients require life-long immunosuppression to prevent rejection. Individuals are prioritized for transplant by mortality risk and severity of illness criteria developed by Organ Procurement and Transplantation Network and United Network of Organ Sharing.
Allogeneic Pancreas Transplant
In 2023, 46,630 transplants were performed in the United States procured from almost 16,000 deceased donors and 6,900 living donors. Pancreas-kidney transplants were the fifth most common procedure, with 812 transplants performed in 2023. Pancreas-alone transplants were the sixth most common procedure, with 102 transplants performed in 2023.
Pancreas transplantation occurs in several different scenarios such as (1) a diabetic individual with renal failure who may receive a simultaneous cadaveric pancreas plus kidney transplant; (2) a diabetic individual who may receive a cadaveric or living-related pancreas transplant after a kidney transplantation (pancreas after kidney); or (3) a non-uremic diabetic individual with specific severely disabling and potentially life-threatening diabetic problems who may receive a pancreas transplant alone.
Data from the United Network for Organ Sharing and the International Pancreas Transplant Registry indicate that the proportion of simultaneous pancreas plus kidney transplant recipients worldwide who have type 2 diabetes has increased over time, from 6% of transplants between 2005 and 2009 to 9% of transplants between 2010 and 2014. Between 2010 and 2014, approximately 4% of pancreas after kidney transplants and 4% of pancreas alone transplants were performed in individuals with type 2 diabetes. In 2022, individuals with type 2 diabetes accounted for 22.4% of all pancreas transplants, according to data from the Organ Procurement and Transplantation Network and the Scientific Registry of Transplant Recipients.
KEY POINTS:
The most recent literature update was performed through June 24, 2024.
Summary of Evidence
For individuals who have insulin-dependent diabetes who receive a pancreas transplant after a kidney transplant, the evidence includes retrospective studies and registry studies. Relevant outcomes are overall survival (OS), change in disease status, and treatment-related mortality and morbidity. Data from national and international registries have found relatively high individual survival rates with a pancreas transplant after a kidney transplant (e.g., a 3-year survival rate of 94.5%). Single-center retrospective studies have found similar individual survival and death-censored pancreas graft survival rates with a pancreas transplant after a kidney transplant or a simultaneous pancreas and kidney (SPK) transplant. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals who have insulin-dependent diabetes with uremia who receive SPK transplants, the evidence includes retrospective studies and registry studies. Relevant outcomes are OS, change in disease status, and treatment-related mortality and morbidity. Data from national and international registries have found relatively high individual survival rates after SPK transplant. A retrospective analysis found a higher survival rate in individuals with type 1 diabetes who had an SPK transplant versus those on a waiting list. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals who have insulin-dependent diabetes and severe complications who receive pancreas transplant alone, the evidence includes registry studies. Relevant outcomes are OS, change in disease status, and treatment-related mortality and morbidity. Data from international and national registries have found that graft and individual survival rates after pancreas transplant alone have improved over time (e.g., 3-year survival of 94.9%). The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
For individuals who have had a prior pancreas transplant who still meet criteria for a pancreas transplant who receive pancreas retransplantation, the evidence includes retrospective studies and registry studies. Relevant outcomes are OS, change in disease status, and treatment-related mortality and morbidity. National data and specific transplant center data have generally found similar graft and individual survival rates after pancreas retransplantation compared with initial transplantation. The evidence is sufficient to determine that the technology results in an improvement in the net health outcome.
Practice Guidelines and Position Statements
The Organ Procurement and Transplantation Network
The Organ Procurement and Transplantation Network updated its comprehensive list of transplant-related policies, most recently in May 2024.
For pancreas registration:
“Each candidate registered on the pancreas waiting list must meet one of the following requirements:
- Be diagnosed with diabetes
- Have pancreatic exocrine insufficiency
- Require the procurement or transplantation of a pancreas as part of a multiple organ transplant for technical reasons.”
For combined kidney plus pancreas registration: “Each candidate registered on the kidney-pancreas waiting list must be diagnosed with diabetes or have pancreatic exocrine insufficiency with renal insufficiency.”
U.S. Preventive Services Task Force Recommendations

This medical policy is not an authorization, certification, explanation of benefits, or a contract. Eligibility and benefits are determined on a case-by-case basis according to the terms of the member’s plan in effect as of the date services are rendered. All medical policies are based on (i) research of current medical literature and (ii) review of common medical practices in the treatment and diagnosis of disease as of the date hereof. Physicians and other providers are solely responsible for all aspects of medical care and treatment, including the type, quality, and levels of care and treatment.
This policy is intended to be used for adjudication of claims (including pre-admission certification, pre-determinations, and pre-procedure review) in Blue Cross and Blue Shield’s administration of plan contracts.
The plan does not approve or deny procedures, services, testing, or equipment for our members. Our decisions concern coverage only. The decision of whether or not to have a certain test, treatment or procedure is one made between the physician and his/her patient. The plan administers benefits based on the member’s contract and corporate medical policies. Physicians should always exercise their best medical judgment in providing the care they feel is most appropriate for their patients. Needed care should not be delayed or refused because of a coverage determination.
As a general rule, benefits are payable under health plans only in cases of medical necessity and only if services or supplies are not investigational, provided the customer group contracts have such coverage.
The following Association Technology Evaluation Criteria must be met for a service/supply to be considered for coverage:
1. The technology must have final approval from the appropriate government regulatory bodies;
2. The scientific evidence must permit conclusions concerning the effect of the technology on health outcomes;
3. The technology must improve the net health outcome;
4. The technology must be as beneficial as any established alternatives;
5. The improvement must be attainable outside the investigational setting.
Medical Necessity means that health care services (e.g., procedures, treatments, supplies, devices, equipment, facilities or drugs) that a physician, exercising prudent clinical judgment, would provide to a patient for the purpose of preventing, evaluating, diagnosing or treating an illness, injury or disease or its symptoms, and that are:
1. In accordance with generally accepted standards of medical practice; and
2. Clinically appropriate in terms of type, frequency, extent, site and duration and considered effective for the patient’s illness, injury or disease; and
3. Not primarily for the convenience of the patient, physician or other health care provider; and
4. Not more costly than an alternative service or sequence of services at least as likely to produce equivalent therapeutic or diagnostic results as to the diagnosis or treatment of that patient’s illness, injury or disease.
