Coverage under prefix HZS

EPO

This is an Exclusive Provider Organization (EPO) prefix. EPO plans do not cover out-of-network care except in genuine emergencies. Members can see any in-network specialist without a referral from their primary care physician. Claims for out-of-network non-emergency services will be denied.

Medicare Advantage

Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.

HDHP

HDHP coverage under this prefix means the member carries a higher annual deductible in exchange for lower monthly premiums. Claims are processed normally but the member's cost-sharing will be higher than standard plans until the deductible is met. Preventive services are typically the exception and are covered at no cost to the member.
