Plan Type Mix in Walker
Aetna organizes its Walker 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 82-doctor network that offers plans of each type.
A high PPO share means most Aetna doctors in Walker 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 Walker.
Percentages don’t sum to 100% because most doctors participate in several plan types simultaneously.

For Aetna’s Walker 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.

Before scheduling anything inpatient or procedural, call both the doctor’s office and the hospital billing line with your member ID to confirm both sides are in-network for the specific plan you hold.
