Oklahoma AARP® MedicareComplete® SecureHorizons® Plans

The AARP MedicareComplete SecureHorizons plans cover benefits in addition to those included under Original Medicare. Members in some areas may have different plans from which to choose. The plans may include an integrated Medicare Part D prescription drug benefit.

  • AARP MedicareComplete Choice (PPO)

Preferred Provider Organization (PPO) plans offer members access to a network of contracted physicians and hospitals, but also allow them the flexibility to seek covered services from outside of the contracted network, usually at a higher cost. Members do not need a referral for specialty care.

PPO plans are available as either local PPO (certain counties within a state) or regional PPO (RPPO) offerings. RPPOs serve a larger geographic area - either a single state or a multi-state area. RPPOs offer the same premiums, benefits and cost-sharing requirements to all members in the region.

  • AARP MedicareComplete SecureHorizons Plan 1 (HMO)
  • AARP MedicareComplete SecureHorizons Plan 2 (HMO)

Health Maintenance Organization (HMO) plans have a defined network of contracted local physicians and hospitals to provide member care. Generally, members must use these care providers to receive benefits for covered services, except in emergencies. These plans currently require referrals for specialty care.
