Coverage under prefix OTK

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.

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.

PPO

Under this PPO prefix, members are covered for both in-network and out-of-network care. The plan pays a higher percentage of allowed charges when members use participating providers. No gatekeeper or primary care referral is required. Verify the member's specific benefits for cost-sharing details.
