What distinguishes a PPO from an HMO in Medicare Advantage plans?

The distinguishing characteristic of PPOs (Preferred Provider Organizations) compared to HMOs (Health Maintenance Organizations) in Medicare Advantage plans lies in the flexibility of provider access and the referral process. PPOs allow beneficiaries the freedom to see any healthcare provider, both inside and outside of their network, without needing to obtain a referral. This can be particularly beneficial for individuals who may want a broader range of healthcare options or wish to visit specialists without going through a primary care provider.

In contrast, HMOs typically require individuals to choose a primary care physician (PCP) who serves as a gatekeeper for all healthcare services. To see a specialist or receive non-emergency care outside the HMO's network, a referral from the PCP is necessary. This structured approach can help manage costs and streamline care but reduces flexibility.

Thus, the correct answer correctly highlights that PPOs provide greater flexibility in accessing healthcare services and do not necessitate referrals, whereas HMOs are more restrictive in these respects. This understanding is crucial for beneficiaries when choosing a plan that fits their healthcare needs and preferences.
