MA law doesn’t force insurance providers to cover gender-affirming hair electrolysis, so most don’t. Trans women with facial hair and cis women suffering from hirsutism are all expected to live with their beards and hairy shoulders.
Washington, Oregon, California and other states have laws on the books making it illegal for medical insurance providers to deny coverage of treatment for these conditions.
MA doesn’t get to do victory laps for its progressive bone fides until it gets with the program and takes care of its women.
