SB 218 Montana Senate · 2025 Regular Session

Provide for private right of action for injuries caused by certain medical interventions to treat gender dysphoria

SB 218 establishes a private right of action, allowing minors, their legal guardians, or estates to file civil lawsuits against healthcare professionals and physicians. These lawsuits can be brought for injuries caused by specific medical interventions, including certain surgeries, hormone therapies, and puberty blockers, when provided to minors to treat gender dysphoria. Liability may arise if the injury is proximately caused by a deviation from the applicable medical standard of care. The bill sets a statute of limitations for these actions and clarifies that it does not apply to treatments for medically verifiable disorders of sex development or complications from prior medical treatments.

MODERATE
This bill expands the list of medical treatments subject to strict liability lawsuits for minors, specifically adding estrogen therapy and puberty blockers for male patients. It also broadens the definition of eligible claimants to include individuals with disorders of sex development and those seeking treatment based on evidence-based clinical needs, rather than limiting claims only to those with ambiguous biological traits.
Scope change
The bill's scope expanded from covering only female minors receiving specific treatments to also covering male minors receiving estrogen and puberty blockers, and it broadened the types of patients eligible to file claims.
SCOPE

Added liability for treating male minors with supraphysiologic doses of estrogen and puberty blockers.

ELIGIBILITY

Expanded eligibility to include individuals with medically verifiable disorders of sex development and those receiving clinically appropriate, evidence-based treatments.

DEFINITION

Added a specific definition for 'female' based on biological characteristics like XX chromosomes and egg production.

REQUIREMENT

Changed the statute of limitations from a fixed 25-year window to a 2-year window starting from when the injury and its cause are discovered.
