(2) Ensure that an enrollee cost-sharing obligation is included, if certain conditions are met, in the enrollee's in-network deductible and maximum out-of-pocket expenses; and

(3) If the plan is issued or renewed after December 31, 2018, publish and maintain a provider directory with information on contracting providers that deliver health care services to the plan's enrollees.
