Why comparing networks and costs matters
Choosing a health plan isn’t just about finding the lowest monthly premium. Networks determine which doctors, hospitals, and specialists will treat you at in-network rates, and plan design (deductible, copays, coinsurance, and out-of-pocket maximums) determines how much you actually pay when care is delivered. Failing to compare both can lead to higher yearly expenses, care interruptions, or longer waits for needed treatment.

Authoritative resources such as HealthCare.gov and Centers for Medicare & Medicaid Services (CMS) provide searchable directories and plan documents you should consult while comparing plans (HealthCare.gov; CMS). Use those listings to verify whether your preferred providers and drugs are in-network.
Practical, step-by-step method to compare networks and costs
Follow these steps in order to compare plans objectively.
- Inventory your health needs
- List all current providers, specialists, and clinics you or your dependents use. Include primary care, mental health, ongoing prescriptions (with dosages), and expected services for the next 12 months (surgeries, pregnancies, therapy, etc.).
- Note any upcoming care that would push costs into your deductible or out-of-pocket maximum.
- Identify candidate plans and get plan documents
- For employer plans, ask HR for the Summary of Benefits and Coverage (SBC) for each option.
- For Marketplace or individual plans, download the SBC and the provider directory for each plan you’re evaluating from HealthCare.gov or the insurer’s website.
- Confirm provider network status — don’t rely on memory
- Use the insurer’s online provider directory and call the provider’s office to confirm they still accept the plan; directories can lag behind changes.
- Pay attention to facility-level networks: a hospital may be in-network, but a specialist or an anesthesiologist working there might be out-of-network.
- Compare cost components — not just premiums
- Premium: monthly fee for having coverage.
- Deductible: how much you must pay before insurance starts sharing costs.
- Copayment: fixed amount (e.g., $30) for a visit or service.
- Coinsurance: percentage you pay after the deductible (e.g., 20%).
- Out-of-pocket maximum: the cap on what you pay in a plan year (excluding premiums).
Calculate a realistic “annual cost” for each plan: (annual premium) + (expected medical expenses paid under plan design). Use conservative estimates for major events — a hospital stay, lab work, or ongoing specialty visits.
- Check pharmacy coverage (the formulary)
- Verify that key prescriptions are covered and note tiered cost-sharing and any prior authorization or step therapy rules. Specialty drugs can be the most significant driver of out-of-pocket costs.
- Consider network breadth vs. convenience
- Narrow networks (often lower premiums) may exclude high-cost specialty providers you need.
- Broader networks (PPOs) usually cost more but offer flexibility and less risk of balance billing. If continuity with a specific specialist is important, favor plans that include them.
- Understand out-of-network rules and balance billing
- Preferred Provider Organizations (PPOs) and Point-of-Service (POS) plans can cover out-of-network care at higher cost; HMOs and Exclusive Provider Organizations (EPOs) typically do not.
- Surprise or balance billing occurs when an out-of-network provider bills you for the difference between their charge and what the insurer pays. Federal and state laws reduce surprises for emergency care but not always for ancillary providers (anesthesiology, radiology). Check state rules and plan protections.
- Factor in non-financial differences
- Referral requirements (HMOs often require primary care referrals to see specialists).
- Prior authorization processes can delay care; review the plan’s prior authorization rules.
- Telehealth availability, behavioral health access, and after-hours care.
- Run example scenarios
- Low-user scenario: only preventive care and a few PCP visits. Which plan has lower combined premium + copays?
- Moderate-user scenario: several specialist visits and prescriptions. Run the numbers to see whether a higher premium plan with lower deductible or copays is cheaper.
- High-user scenario: surgery or hospitalization. A plan with lower out-of-pocket maximum may be best.
Use a simple spreadsheet to compare total expected annual cost for each scenario.
Real-world examples (illustrative)
Example 1: Young adult, low expected utilization
- Plan A: Low premium, higher deductible, narrow network — cheaper if you rarely use care.
- Plan B: Higher premium, lower deductible, broader network — better if you expect more visits.
After estimating two PCP visits and zero hospital stays, Plan A’s lower premium kept total cost down for the year.
Example 2: Chronic condition requiring a named specialist
- Plan C excludes the specialist from its network. Although Plan C has a lower premium, the specialist’s out-of-network bills and higher coinsurance made Plan D (higher premium but in-network) the more cost-effective option over 12 months.
These stories mirror cases I’ve handled in my practice: clients who saved money by choosing plans that covered their ongoing specialists despite higher monthly premiums.
Special considerations: Medicare, Medicaid and HSAs
- Medicare beneficiaries should compare Original Medicare vs. Medicare Advantage plans by checking provider participation and supplemental costs on Medicare.gov and each plan’s provider list (CMS). See FinHelp’s Medicare Part A and Part B definitions for context. (https://finhelp.io/glossary/medicare-part-a-hospital-insurance/)(https://finhelp.io/glossary/medicare-part-b-medical-insurance/)
- Medicaid and CHIP vary by state; check your state Medicaid agency for network rules.
- If you’re considering a High-Deductible Health Plan (HDHP) with an HSA, confirm whether the HDHP’s network and drug formulary meet your needs before prioritizing tax advantages. (See: High-Deductible Health Plan (HDHP) with HSA) (https://finhelp.io/glossary/high-deductible-health-plan-hdhp-with-hsa/)
Common mistakes people make
- Focusing only on premiums and ignoring deductibles and coinsurance.
- Assuming an in-network hospital means every provider there is in-network — verify each clinician group.
- Forgetting to check the formulary and prior authorization rules for specialty medications.
- Not calling the provider to confirm network participation; directories can be out of date.

- CMS plan and provider information for Medicare and Marketplace plans. (https://www.cms.gov)
- State insurance department websites for complaints and consumer protections.
- Use FinHelp’s glossary resources for related topics like Form 1095-A, which matters if you enroll through the Marketplace. (https://finhelp.io/glossary/form-1095-a-health-insurance-marketplace-statement/)
Professional tips for negotiating and protecting yourself
- Ask your provider about discounted cash rates if they are out-of-network and you’ll be paying privately — sometimes you can negotiate a lower price up front.
- For scheduled procedures, ask the provider for an itemized estimate and ask whether all clinicians (surgeon, anesthesiologist, pathology) will be in-network.
- Document phone calls with insurer and provider; save the representative’s name, date, and confirmation numbers.
Quick decision checklist
- Are your primary providers and required specialists in-network?
- Does the formulary cover your prescriptions affordably?
- What is the realistic annual cost under low, medium, and high utilization scenarios?
- Are there limits on mental health, physical therapy, or durable medical equipment that you need?
- Will you need referrals or prior authorization that could affect timely access?
Frequently asked questions
Q: What if my doctor leaves the network mid-year?
A: If your doctor leaves, you can either continue with out-of-network care (higher cost) or switch doctors. Some plans offer continuity of care exceptions for ongoing treatments — ask your insurer. Check plan documents and state consumer protections.
Q: How do I estimate total yearly cost?
A: Add annual premiums plus the out-of-pocket costs you expect under the plan’s rules (deductible, copays, coinsurance), then compare across plans under at least two utilization scenarios.
Q: Can I appeal network denials?
A: Yes. Insurers have internal appeals and external review options. For Marketplace plans, the Marketplace and state regulators can help. Keep documentation and ask about expedited reviews for urgent care needs.
Final notes and disclaimer
Comparing health insurance networks and costs takes time, but it’s one of the best investments you can make to avoid surprise expenses and ensure continuity of care. The guidance here is educational and general; it does not substitute for personalized advice. For plan-specific questions, contact your insurer, a licensed insurance broker, or a financial advisor.
