Plan Type Mix in Buffalo Grove

UnitedHealthcare organizes its Buffalo Grove 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 1,160-doctor network that offers plans of each type.

A high PPO share means most UnitedHealthcare doctors in Buffalo Grove 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 UnitedHealthcare 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 Buffalo Grove.

For UnitedHealthcare’s Buffalo Grove 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.
