The Plan Comparison Checklist: Compare 2027 Tennessee Marketplace Plans Apples to Apples

The short version: don't pick a plan on premium alone. Do this, in order, with your doctor list and your prescription list in front of you: (1) compare the monthly premium after any tax credit; (2) compare the deductible, copays, and coinsurance; (3) check the out-of-pocket maximum — the federal ceiling for 2027 is $12,000 individual / $24,000 family; (4) verify YOUR doctors and hospital are in-network — check the directory and call; (5) check YOUR prescriptions in the formulary and note the tier; (6) if your income is 100%–250% of the poverty level, compare silver plans first for cost-sharing reductions. Do it all in HealthCare.gov window shopping, side by side.

Step 1: Gather your two lists before you open HealthCare.gov

• Your providers: every doctor you see regularly, your preferred hospital, your pharmacy if you have one.
• Your prescriptions: every medication, including dosages. You'll check each one against each plan's formulary.

These lists are the whole game. Everything else on this page is arithmetic; these lists decide which plans are even candidates.

Step 2: Compare the monthly premium — after the credit

HealthCare.gov shows you the premium you pay after your estimated premium tax credit. Compare those numbers, not the sticker prices — a gold plan can cost less out of pocket per month than a bronze plan once credits are applied. Remember that for 2027, credits generally go to households at 100%–400% of the poverty level, with the hard cliff at 400%. Estimate your credit →

Step 3: Compare the deductible, copays, and coinsurance — together

• Deductible: what you pay before the plan starts sharing most costs. Lower isn't automatically better — a low-deductible plan with a high premium can cost more over the year than a high-deductible plan you barely use.
• Copays: flat fees for visits and prescriptions. Note which services carry copays before you meet the deductible.
• Coinsurance: your percentage share after the deductible. A 20% coinsurance on an expensive procedure adds up fast.

The honest way to compare: sketch your own year. If you're healthy and rarely see a doctor, weight the premium. If you take regular prescriptions or expect a procedure, weight the deductible and the out-of-pocket max. How these costs work in practice →

Step 4: Check the out-of-pocket maximum

This is your worst-case number for covered, in-network care: once you've paid this much in deductibles, copays, and coinsurance, the plan pays 100% for the rest of the year. For 2027, the federal ceiling is $12,000 for an individual and $24,000 for a family — plans can set it lower, but not higher. If you're comparing two similar premiums, the lower out-of-pocket max is the safer plan.

Step 5: Verify the network — directory plus a phone call

A plan only saves you money if your providers are in it. For each plan on your shortlist:

1. Look up your doctors and hospital in the plan's online provider directory on HealthCare.gov.
2. Call your doctor's office and ask which of the plans you're considering they accept. Directories go stale; the billing office knows.
3. If you live outside a metro, factor in driving distance to in-network hospitals and specialists — a cheap plan with a long drive for covered care isn't the cheap plan. How networks work → · Rural Tennessee guide →

Step 6: Check the formulary for YOUR prescriptions

For each plan, look up each of your medications: Is it covered? On which tier? Tiers decide what you pay — a drug on a high specialty tier can cost far more per month than any premium difference between plans. Note any restrictions, like prior authorization or step therapy. If a medication isn't covered at all, that plan is off your list (or budget the full cash price). Formularies explained →

Step 7: If your income is 100%–250% of the poverty level, start with silver

Cost-sharing reductions only attach to silver plans — they lower your deductible, copays, and out-of-pocket max beyond what's printed on the tin. If your income is in this band, a silver plan with CSRs often beats both bronze (cheaper premium, much higher cost when you're sick) and gold (higher premium) on total yearly cost. Compare the CSR silver plans against everything else before deciding. Subsidies explained →

Step 8: Sanity-check the metal tier

• Bronze: lowest premiums, highest costs when you need care. Fits healthy people who mainly want protection against the big, expensive year — with one caveat (see the note below).
• Silver: the middle ground — and the only tier that carries cost-sharing reductions.
• Gold: higher premiums, lower costs at the point of care. Often the best total deal for people with regular medical needs, especially after tax credits.
• Catastrophic: available only in limited circumstances (under 30, or with a hardship/affordability exemption). Low premiums, very high deductibles.

Step 9: Run your worst-case year

For your top two or three plans, add it up: (12 × monthly premium after credit) + out-of-pocket maximum. That's the most you can pay for covered in-network care in a bad year. If the "cheaper" plan has a much worse worst case, it isn't cheaper — it's a gamble. Then pick the plan whose worst case you can live with and whose doctors you can actually see.

Frequently asked questions

What's the single biggest mistake people make comparing plans? Comparing sticker premiums instead of post-credit premiums — and never checking whether their doctors are in-network. Those two mistakes together explain most buyer's remorse.

Is a lower deductible always better? No. A lower deductible usually means a higher monthly premium. The right comparison is total yearly cost for your expected care: premium × 12, plus what you'd pay in deductibles, copays, and coinsurance.

What does the out-of-pocket maximum actually cap? Your spending on covered, in-network care — deductibles, copays, and coinsurance count toward it. Once you hit it, the plan pays 100% of covered in-network costs for the rest of the year. For 2027 the federal ceiling is $12,000 individual / $24,000 family.

How do I check whether my prescription is covered? Use each plan's formulary (drug list) on HealthCare.gov during window shopping. Look up every medication by name, note the tier, and check for restrictions like prior authorization or step therapy.

Do I really need to call my doctor's office? Can't I trust the directory? Do both. Directories can lag behind contract changes by months. A two-minute call to the billing office confirms what the directory claims.

When can I compare 2027 plans? HealthCare.gov window shopping typically opens in late October 2026, ahead of open enrollment (November 1, 2026 – January 15, 2027). Enroll by December 15, 2026 for coverage starting January 1, 2027. Full enrollment calendar →
