In-Network
Doctors, hospitals, labs, and pharmacies that have signed a contract with your insurance company to provide care at pre-negotiated rates. Using in-network providers gives you the lowest cost-share and full plan benefits.

In-network providers are doctors, hospitals, labs, pharmacies, and other healthcare professionals who have signed a contract with your insurance company. That contract sets the price the insurer will pay for each service, and it commits the provider to accept that price as payment in full.
Why in-network costs less
When you see an in-network provider, three things happen automatically:
- The provider bills your insurance at the contracted rate, not the higher “list price”
- Your copay or coinsurance counts toward your in-network deductible and out-of-pocket maximum
- You are not billed the difference between what the provider would normally charge and what the insurance allows
That last point matters. Out-of-network providers can send you a separate bill for the gap. In-network providers cannot.
How network rules differ by plan type
The plan type you pick determines how strict the network rules are:
- HMO: in-network only, except for emergencies. Out-of-network care is not covered.
- EPO: in-network only, except for emergencies. Similar to HMO but typically without a referral requirement.
- PPO: in-network preferred. Out-of-network is covered but at a higher coinsurance and a separate deductible.
If you have an HMO or EPO and you see an out-of-network provider for non-emergency care, you may pay the full bill yourself.
Verify before every visit
Networks change. A provider who was in-network in January may drop the contract in June. Before each new appointment:
- Call the provider’s office and ask: “Are you currently in-network with [your plan name and ID]?”
- Cross-check on the insurer’s online provider directory
- Confirm the specific location is in-network — some providers contract per office, not per provider
For planned procedures (surgery, imaging, specialist referrals), also confirm that the anesthesiologist, radiologist, pathologist, and any assistant providers are in-network. Federal protection under the No Surprises Act covers many ancillary providers at in-network facilities, but verifying first prevents disputes.
When the network is too thin
If you cannot find an in-network provider for the care you need within a reasonable distance, you may be able to request out-of-network care at in-network rates under network adequacy rules. Document every call you make to in-network providers so you have evidence.
