Concerning the administration of vision benefits.

HB 1770 clarifies the definition of "vision benefit manager" within Washington state's health care administration rules. It specifies that vision benefit managers - entities managing vision care benefits for health plans - are now explicitly included under the broader definition of "health care benefit manager" in existing law. This affects how vision benefits are administered for employees covered by public employees' and school employees' health benefit programs. The bill adds specific language to define vision benefit managers' roles, such as processing claims and determining coverage for vision services, while excluding certain entities like public benefit boards from this classification.
