RELATING TO HEALTH.

HB 598 prohibits insurance companies from requiring patients to pay copays, deductibles, or other cost-sharing for diagnostic and supplemental breast exams ordered by doctors to investigate concerns or monitor conditions. This directly affects patients needing these specific exams, such as follow-up tests after abnormal mammograms. The bill mandates that insurers cover these exams fully without patient cost-sharing, applying only to diagnostic and supplemental procedures - not routine screenings. It represents a policy change to reduce financial barriers for medically necessary breast examinations.
