Provider Network

A provider network is the group of doctors, hospitals, specialists, labs, pharmacies, and other health care providers that have agreed to accept your insurance plan’s negotiated rates. Using providers in your network is almost always significantly cheaper than going outside it.

Network size and composition vary widely between plans and carriers. A narrow network plan may have lower premiums but fewer provider choices. A broad network plan offers more flexibility but typically costs more per month.

Your network affects more than just cost — it determines which providers you can see at all on certain plan types:

  • HMO: In-network only (no out-of-network coverage except emergencies)
  • EPO: In-network only (no out-of-network coverage except emergencies)
  • PPO: In-network preferred, out-of-network covered at higher cost
  • POS: In-network preferred, out-of-network covered with a referral

Before enrolling in any plan, use the insurer’s provider directory to verify that your current doctors and any specialists you see are in the network. Directories can be outdated — always call the provider’s office to confirm as well.

Frequently Asked Questions

Can my doctor leave my network after I enroll?

Provider networks can change during the year. A doctor who is in-network when you enroll may leave the network mid-year. If that happens with a specialist you’re actively treating, you may be eligible for continuity of care protections that allow you to complete a course of treatment in-network even after the provider leaves. Contact your insurer immediately if this happens.

What if I need to see a provider outside my network?

Not all plans cover out-of-network care — HMO and EPO plans generally don’t, except for emergencies. If you’re on a PPO or POS, out-of-network care is covered but at a higher cost share, and you may face a separate out-of-network deductible. Always verify your plan type before seeking care from a provider outside your network.
