Plans differ mainly by **network rules** ([HMO, PPO, EPO, POS, or HDHP](https://insurafaq.com/insurance/types-of-health-insurance-plans/)) and by **cost-sharing structure** ([premium, deductible, copay, coinsurance, and out-of-pocket maximum](https://insurafaq.com/insurance/copay-vs-coinsurance-vs-deductible/)). Marketplace shoppers should also review [the 2026 ACA subsidy update](https://insurafaq.com/blog/2026-aca-subsidy-changes) and the [health insurance enrollment guide](https://insurafaq.com/insurance/health-insurance-enrollment-guide/) for timing, eligibility, and special enrollment periods. ## Key takeaways - **What plans pay for** — preventive visits, primary and specialist care, hospital services, prescription drugs, and mental health services. - **Network rules matter** — [HMO, PPO, EPO, POS, or HDHP](https://insurafaq.com/insurance/types-of-health-insurance-plans/) shape access and referral rules. - **Cost-sharing structure** — [premium, deductible, copay, coinsurance, and out-of-pocket maximum](https://insurafaq.com/insurance/copay-vs-coinsurance-vs-deductible/) determine total spend. - **Marketplace subsidy update** — see [the 2026 ACA subsidy update](https://insurafaq.com/blog/2026-aca-subsidy-changes) for current subsidy rules. - **Enrollment timing** — the [health insurance enrollment guide](https://insurafaq.com/insurance/health-insurance-enrollment-guide/) covers eligibility and special enrollment periods. - **Common exclusions** — out-of-network care carries higher cost exposure, non-formulary drugs may require prior authorization, and adult routine [dental](https://insurafaq.com/insurance/dental-insurance/) and [vision](https://insurafaq.com/insurance/vision-insurance/) care are typically excluded. ## Overview Health insurance helps cover the cost of medical care, from routine checkups to major procedures. Plans differ by network, cost-sharing structure, and covered services, so comparing benefits and total out-of-pocket costs is essential. ## Find the right health insurance guide Choose a starting point based on the task you need to complete. ### Choosing a plan - [Compare health plan types](https://insurafaq.com/insurance/types-of-health-insurance-plans/) — understand HMO, PPO, EPO, POS, and HDHP options. - [Explore coverage when self-employed](https://insurafaq.com/insurance/self-employed-health-insurance/) — review options for freelancers and contractors. ### Understanding costs - [Compare copays, coinsurance, and deductibles](https://insurafaq.com/insurance/copay-vs-coinsurance-vs-deductible/) — distinguish the main cost-sharing terms. - [Understand the out-of-pocket maximum](https://insurafaq.com/insurance/out-of-pocket-maximum-explained/) — see which expenses count toward the limit. - [Review health insurance costs](https://insurafaq.com/insurance/health-insurance-cost/) — put premiums and other expenses in context. ### Getting care and enrolling - [Check health insurance networks](https://insurafaq.com/insurance/health-insurance-networks/) — understand provider access before arranging care. - [Find enrollment guidance](https://insurafaq.com/insurance/health-insurance-enrollment-guide/) — review enrollment timing and eligibility. - [Follow a health insurance claim](https://insurafaq.com/insurance/health-claims-step-by-step/) — work through the claims process. ## What health insurance typically covers - **Preventive care:** annual physicals, screenings, and vaccines. - **Primary and specialist care:** office visits, diagnostics, and referrals. - **Hospital services:** inpatient stays, surgeries, and emergency care. - **Prescription drugs:** medications under a plan’s formulary. - **Mental health services:** therapy, counseling, and inpatient treatment. ## Common exclusions and limitations - **Out-of-network costs:** planned care may cost more or be excluded, depending on the plan. [Marketplace plan network rules](https://www.healthcare.gov/choose-a-plan/plan-types/) differ; emergency care has separate protections. - **Non-formulary drugs:** may require prior authorization or pay full price. - **Cosmetic procedures:** generally excluded unless medically necessary. - **Coverage limits:** some services have visit caps or require referrals. - **Routine dental and vision care:** generally excluded from adult health plans; both are typically bought as standalone [dental insurance](https://insurafaq.com/insurance/dental-insurance/) or [vision insurance](https://insurafaq.com/insurance/vision-insurance/) coverage. ## Key cost components - **Premium:** what you pay monthly to keep coverage active. - **Deductible:** what you pay for covered services subject to the deductible before the plan starts paying for those services. Some services are covered before you meet it; check your plan's benefits. [HealthCare.gov explains deductible exceptions.](https://www.healthcare.gov/glossary/deductible/) - **Copay/coinsurance:** your share of a covered service's cost; whether the deductible applies first depends on the service and plan. [Review how deductibles work.](https://www.healthcare.gov/glossary/deductible/) - **Out-of-pocket maximum:** for Marketplace plans, the most you pay in a plan year in deductibles, copays, and coinsurance for covered in-network services. After you reach it, the plan pays 100% of covered in-network benefits. Premiums, noncovered services, out-of-network care, and charges above the allowed amount do not count toward this limit. Check your plan's Summary of Benefits and Coverage for its rules. [HealthCare.gov explains what the limit includes and excludes.](https://www.healthcare.gov/glossary/out-of-pocket-maximum-limit/) Confused by cost-sharing terms? Our [copay vs coinsurance vs deductible comparison](https://insurafaq.com/insurance/copay-vs-coinsurance-vs-deductible/) breaks down each one. ## How to compare plans 1. **Check network fit:** verify your doctors and preferred hospitals are included. 2. **Estimate total cost:** add premiums and typical out-of-pocket spending. For a breakdown of average costs by plan type, see our [health insurance cost guide](https://insurafaq.com/insurance/health-insurance-cost/). 3. **Review drug coverage:** ensure your medications are on the formulary. 4. **Consider plan type:** HMO, PPO, or HDHP depending on flexibility needs.

Learn how to choose between these tax-advantaged accounts in our [HSA vs FSA guide](https://insurafaq.com/insurance/hsa-vs-fsa/). - If you're self-employed, see our [guide to health insurance for freelancers and contractors](https://insurafaq.com/insurance/self-employed-health-insurance/). - Always read the summary of benefits and coverage (SBC) for details. ## Frequently asked questions ### Is preventive care really free? Often yes, when using in-network providers, but confirm your plan’s preventive services list. ### Can I keep my current doctor? Only if they are in-network for the plan you select; check before enrolling. ### What happens if I go out of network? For planned care, your costs and coverage depend on the plan: PPOs allow out-of-network care at an extra cost, while HMOs generally do not cover it except in an emergency. [Review Marketplace network types.](https://www.healthcare.gov/choose-a-plan/plan-types/) Emergency room services have separate protections: Marketplace plans cannot charge higher copays or coinsurance solely because the hospital is out of network, though a deductible may apply. [HealthCare.gov explains emergency care.](https://www.healthcare.gov/using-marketplace-coverage/getting-emergency-care/) ## Practical next steps If you are choosing a health plan, start by listing your expected medical needs for the year: regular prescriptions, specialist visits, planned procedures, and any chronic conditions. Then estimate your total annual cost under each plan by adding premiums plus likely out-of-pocket spending. The cheapest premium is not always the cheapest plan once you factor in deductibles and copays. Check that your preferred doctors and hospitals are in-network before enrolling. If you take prescription medications, search each plan's formulary to confirm your drugs are covered and at what tier. For more details on timing and eligibility, see our [enrollment guide](https://insurafaq.com/insurance/health-insurance-enrollment-guide/). ## Information to gather before choosing a plan - A list of your current doctors, specialists, and preferred hospitals. - All prescription medications with dosages and frequency. - Your estimated household income (needed for marketplace subsidy calculations). - Any planned procedures or treatments for the coming year. - Your current plan's Summary of Benefits and Coverage (SBC) for comparison. ## Common health insurance mistakes - **Choosing the lowest premium without checking total cost.** A low premium with a $7,000 deductible can cost more than a moderate premium with a $1,500 deductible if you use medical services regularly. - **Not verifying your doctor is in-network.** For planned visits, confirm the provider's network status with your plan before booking. Out-of-network coverage and cost-sharing vary by plan; HMOs generally exclude out-of-network care except in an emergency. [Check the plan's network rules.](https://www.healthcare.gov/choose-a-plan/plan-types/) - **Ignoring the formulary.** A plan that does not cover your medications at a reasonable tier can add hundreds of dollars per month. - **Missing enrollment deadlines.** Outside of open enrollment, you can only enroll during a [special enrollment period](https://insurafaq.com/insurance/health-insurance-enrollment-guide/) triggered by a qualifying life event. - **Skipping preventive care.** Most plans cover preventive services at no cost when you use in-network providers. Annual checkups catch problems early and reduce long-term costs. ## Annual health plan review Review your plan during each open enrollment period: - Check whether your doctors and hospitals are still in-network for next year's plan. - Verify that your prescriptions are still on the formulary and at the same cost tier. - Recalculate your expected medical expenses and compare plan options using total annual cost (premiums + expected out-of-pocket). - Check for subsidy eligibility changes if your income has shifted. - Review whether an HSA-eligible high-deductible plan makes sense for your situation.
