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.

Plan Type Mix in Guerneville
UnitedHealthcare organizes its Guerneville 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 18-doctor network that offers plans of each type.
A high PPO share means most UnitedHealthcare doctors in Guerneville 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 Guerneville.
Percentages don’t sum to 100% because most doctors participate in several plan types simultaneously.

Large affiliation counts indicate that UnitedHealthcare has a durable relationship with the facility, which typically means smoother prior-authorizations for admissions, lab work, and follow-up care coordinated under one roof.

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.
