Wyoming law lets eligible patients receive certain stem cell treatments

The law allows a patient to receive, and a physician to provide, certain stem cell treatments that lack federal approval. The treatment uses the patient's own mesenchymal stem cells. It cannot use biological material derived directly or indirectly from an abortion. The treatment must have current institutional review board approval or involve an investigational drug, biological product, or device that meets the law's definition. Stem cells must meet current manufacturing standards. A registered physician must provide or directly supervise treatment, and the patient or legal representative must give written consent after learning about the treatment, its risks, and its costs. Providers may choose whether to offer treatment; the law does not require them to do so. The law takes effect July 1, 2026; this date applies to all its provisions.

The state medical board must keep and publish a public list of physicians registered to provide this treatment. The list covers physicians registered under the Stem Cell Freedom Act. This requirement takes effect July 1, 2026.

State and local officials may not prohibit or try to prohibit a patient's access to stem cell treatment. This applies to Wyoming state and local officials, employees, and agents. Licensed health care providers may still give counseling, advice, or recommendations that follow medical standards of care. This rule takes effect July 1, 2026.

The law bars the medical board from taking action against a physician's license solely for recommending or providing stem cell treatment. This applies to physicians recommending treatment or performing it under the law. The recommendation or treatment must follow medical standards of care, and the physician must be registered to provide treatment under the law. This rule takes effect July 1, 2026.
