Provide for the hearing aid coverage act

This bill expands mandatory health insurance coverage in Montana to include hearing loss treatment for individuals of all ages, not just children. It amends existing state insurance laws to require group health plans to cover hearing loss treatments under the same provisions currently required for children with hearing loss. The legislation directly affects health insurance providers and policyholders by mandating that insurance contracts include these specific coverage provisions. The bill does not create new funding or change eligibility requirements, but rather updates existing statutory language to align coverage requirements with the age range of affected individuals.
