An HMO (Health Maintenance Organization) requires you to pick a primary-care doctor and get referrals for most specialist care, usually in exchange for lower premiums. An EPO (Exclusive Provider Organization) is in-network only, like an HMO, but skips the referral requirement. A POS (Point of Service) plan blends HMO-style in-network with PPO-style out-of-network options. Your plan name is on your member ID card.
Aetna does not sell consumer ACA marketplace plans or Medicare Advantage in Willowbrook. The networks above are commercial offerings, typically distributed through employer group plans, self-funded ERISA arrangements, and similar group products.

Plan Type Mix in Willowbrook
Aetna organizes its Willowbrook network into several plan types, each with different rules about which doctors you can see and what referrals you need. The bars below show the unique-provider share of the 168-doctor network that offers plans of each type.
A high PPO share means most Aetna doctors in Willowbrook accept the insurer’s broader preferred-provider plans. these give you maximum choice and don’t require referrals to specialists. A high HMO share signals a tighter gatekeeper model: lower premiums but you usually need your primary-care doctor to refer you before a specialist will bill. EPO and POS bars sit between those two on both flexibility and cost.
Because individual doctors typically participate in multiple Aetna plan types at once, these percentages don’t sum to 100%. the same provider can appear as both PPO and OAP coverage. What the chart tells you is which plan categories have meaningful depth in Willowbrook.
Percentages don’t sum to 100% because most doctors participate in several plan types simultaneously.

For Aetna’s Willowbrook network the breakdown below gives a quick sense of whether you’re picking from a predominantly early-career roster or one weighted toward veteran practitioners.
A network heavy on early-career doctors (0–5 years) often means lower wait times for new patients and exposure to the latest training, while veteran providers (30+ years) typically bring deeper pattern recognition for unusual presentations. A balanced distribution. roughly one-quarter in each bucket. is a healthy signal that the insurer has depth at every career stage, not just new graduates filling out its directory.
