Understanding Insurance Networks

Choosing an in-network doctor is one of the easiest ways to keep costs down. Here's what insurance networks are, what the plan types mean, and how to avoid surprise bills.

In-network vs out-of-network

In-network providers have a contract with your insurance company and charge negotiated rates. You'll usually pay a copay or coinsurance. Out-of-network providers haven't signed a contract — they can charge whatever they want, and your plan may cover little or nothing.

Plan types

  • HMO — Lowest cost. Requires a primary care doctor and referrals. Out-of-network care is generally not covered except for emergencies.
  • PPO — Higher premiums but more flexibility. See specialists without referrals; out-of-network care is partially covered.
  • EPO — Like a PPO without out-of-network coverage. No referrals required.
  • HDHP + HSA — Lower premiums, higher deductible. You pay full negotiated rates until the deductible is met, then insurance kicks in.
  • Medicare — Original Medicare (Parts A & B) accepted by most doctors. Medicare Advantage plans have their own networks.

How to verify a doctor is in-network

  1. Search your plan's online directory.
  2. Call the member services number on your card.
  3. Call the doctor's office and confirm both the doctor and the practice are in-network for your exact plan name.
  4. Get the confirmation in writing or note the date, time, and rep's name.

Avoid surprise bills

Even at an in-network hospital, some providers (anesthesia, radiology, ER physicians) may be out-of-network. The federal No Surprises Act protects you in emergencies and most non-emergency hospital care — but you can still be balance-billed if you sign certain waivers. Don't sign anything you don't understand.
