State Medicaid Body Mass Index Requirements for Solid Organ Transplant Coverage: A 50-State Policy Review

Body mass index (BMI) has long served as a screening tool for assessing procedural risk and is used as an exclusion criterion for insurance coverage. Variation in state Medicaid policies, specifically pre-transplant BMI requirements, may affect transplant eligibility and limit access to transplantation. No published literature summarizes these policies. We conducted a 50-state review of Medicaid policies to identify pre-transplant BMI requirements across solid organ transplantation (heart, lung, liver, kidney, pancreas, intestine).

Public records requests were submitted to state Medicaid offices for relevant policy documents. Policies were categorized as: (1) Restrictive: precludes transplant coverage if a specified weight/BMI cutoff is not met; (2) Somewhat restrictive: no explicit BMI requirements but deference to managed care organization (MCO)/transplant center criteria; or (3) Unrestrictive: no BMI requirements or publicly available MCO/transplant center criteria.

Three states (HI, IA, and NC) had restrictive policies with pre-transplant weight/BMI requirements for coverage of heart, lung, and combined heart-lung transplants. None applied to kidney, liver, pancreas, or intestine transplants. Thirty-two states and DC had somewhat restrictive policies; 15 had unrestrictive policies.

Most state Medicaid policies do not contain explicit BMI eligibility requirements for transplant coverage. Instead, BMI-based criteria typically originate from MCOs/transplant centers that establish and enforce their own criteria.
