An HMO or EPO generally limits covered care to network providers except in emergencies; a PPO usually lets you go out of network for more; and a POS plan requires a primary-care referral for specialist visits. The exact benefits depend on the individual plan, so check its documents and provider directory before enrolling.
How the four plan types compare
These are typical U.S. plan-label descriptions, not guarantees about every policy. In-network providers have a contract with the plan; out-of-network providers do not. A primary care provider (PCP) is the clinician who can coordinate routine care and, in some plans, referrals. HealthCare.gov defines these plan types and their general tradeoffs.
| Plan type | Typical network rule | Specialist referral | Main tradeoff |
|---|---|---|---|
| HMO (Health Maintenance Organization) | Generally limits covered care to providers in the HMO network, except emergencies. | Some designs use a PCP to coordinate specialist care; confirm whether your plan requires a referral. | May not suit you if an important doctor or hospital is outside the network. |
| PPO (Preferred Provider Organization) | In-network care generally costs less; out-of-network care may be covered at additional cost. | HealthCare.gov says PPOs allow out-of-network care without a referral, for an additional cost. | Offers more provider flexibility, but out-of-network care can cost more. |
| POS (Point of Service) | In-network care generally costs less. Check the plan documents for whether and how out-of-network care is covered. | Requires a referral from your PCP to see a specialist. | Combines a referral step with an in-network cost advantage; out-of-network benefits vary. |
| EPO (Exclusive Provider Organization) | Generally limits covered services to in-network doctors, specialists, and hospitals, except in an emergency. | CMS says EPOs generally do not require a PCP referral for specialist care; confirm your plan’s rules. | May allow direct specialist access while requiring you to stay in network. |
HealthCare.gov states that “POS plans require you to get a referral from your primary care doctor in order to see a specialist.” That describes the general POS rule; your plan documents govern the specific benefit.
What to check before choosing a plan
Make sure your important providers are in the exact network
Check the directory for your PCP, specialists, preferred hospitals, and any other providers whose care matters to you. Confirm the directory is for the specific plan and network you are considering; a provider’s participation in one plan from an insurer does not establish participation in another. The NAIC advises consumers to understand which providers are in and out of network.
Understand the cost of out-of-network care
Find out whether the plan covers non-emergency out-of-network services, and if so, what deductible, coinsurance, or other charges apply. Out-of-network care can expose you to balance billing: a provider may bill you for the difference between its charge and the amount the plan recognizes. Protections depend on the circumstances and applicable law, so do not assume every bill is protected or that every out-of-network service is covered.
Confirm referral rules
Ask whether you need a PCP referral before seeing a specialist, how to obtain one, and whether exceptions apply. A referral requirement can affect how you arrange care even when the specialist is in network.
Compare total costs and covered benefits
Look beyond the monthly premium. Compare the plan’s out-of-pocket costs and covered services as well as its network and referral rules. HealthCare.gov recommends considering both costs and plan type when choosing; no one plan label establishes which option will cost less overall for you.
Check plans available where and how you enroll
Plan availability, eligibility, provider networks, and prices depend on your location and enrollment context. Compare the actual options offered to you rather than assuming that a plan type or a national description determines local availability or cost.

Where to verify the details
- Evidence of coverage and summary of benefits: Use these plan documents to confirm covered services, referral requirements, cost sharing, and out-of-network terms.
- Insurer provider directory: Search for your providers in the exact plan network, then confirm participation with the insurer or provider if needed.
- Applicable state rules: State comparisons and protections may be specific to that state. For example, the California Department of Insurance’s comparison applies to California and should not be treated as a nationwide statement of insurance rules.
