A health care plan given as an employment benefit pursuant to a collective bargaining agreement contained an enrollment form that complied with Health & Safety Code 1363.1’s requirement that immediately before the employee signature there appear a disclosue of the fact that the plan requires arbitration and that the enrollee waives the right to trial by jury. The plan also provided the new enrollee an explanation of benefits and a supplement to the explanation further explaining mental health care provided by a separate entity. Both of these additional documents contained disclosures regarding the arbitration agreement, but neither required a signature. The supplement didn’t comply with section 1363.1, but that didn’t matter because the entity providing mental health care was not a health care service plan to which section 1363.1 applied.
