That’s not false modesty. A few years ago, I was helping my sister pick a health plan during open enrollment. She handed me her employer’s benefit guide – about 180 pages, tiny font, lots of bold text and asterisks. I read it for an hour and came away with a headache. She asked me “so which plan should I pick?” I said “I don’t know yet. This is intentionally confusing.”
That’s the problem. Health insurance plans are designed to be complex. Complexity benefits the insurer, not you. When you’re confused, you default to what you already have, or you pick the plan with the lowest premium, or you let your HR person decide for you. None of those are optimal.
But you don’t need to read every page. You need to know five numbers and one concept. That’s it. The rest is noise.
Let me walk you through a real Summary of Benefits and Coverage – that’s the standardized form most plans are required to provide. Not the glossy brochure. The actual SBC. It’s usually about 8-12 pages, not 200. You can find it on your insurer’s website or ask HR for it.
Number one: Premium. This is what you pay monthly, regardless of whether you use healthcare. It’s usually deducted from your paycheck pre-tax if you have employer coverage. The premium is the cost of entry. But it’s not the total cost. People make the mistake of picking the lowest premium and then getting crushed by out-of-pocket costs when they need care.
Number two: Deductible. This is what you pay before insurance starts paying. If your deductible is about $5,000, you pay the first about $5,000 of covered services – doctor visits, labs, imaging, prescriptions, hospital stays – before the insurance kicks in. Some plans have separate deductibles for medical and pharmacy. Read carefully.
Number three: Coinsurance. After you meet your deductible, coinsurance is the percentage you still pay. Typical coinsurance is about 20% for most services. So after your about $5,000 deductible, if you have a about $10,000 surgery, you pay about 20% (about $2,000) and insurance pays 80% ($8,000).
Number four: Copay. Flat dollar amount you pay for certain services, like about $30 for a primary care visit or about $50 for a specialist. Copays usually do not count toward your deductible, but they do count toward your out-of-pocket maximum. Some plans use copays instead of coinsurance for certain services.
Number five: Out-of-pocket maximum (OOPM). This is the most important number. This is the most you will pay in a year for covered services, including deductibles, coinsurance, and copays. Once you hit this number, insurance pays 100% of covered services for the rest of the year. For marketplace plans in 2026, the maximum OOPM is around about $9,000 for an individual, about $18,000 for a family. Employer plans can have lower OOPMs.
The one concept: In-network vs. out-of-network. In-network providers have contracts with your insurer. They accept negotiated rates. Your costs are lower. Out-of-network providers do not have contracts. They can bill you for the difference between what insurance pays and what they charge. That’s called balance billing. Some plans have no out-of-network coverage except emergencies. Some have a separate out-of-pocket maximum for out-of-network. Never assume a provider is in-network. Always check.
I remember a woman named Diane. She had a high-deductible health plan with a about $3,000 deductible and a about $6,000 out-of-pocket max. She was healthy, so she thought the low premium was a great deal. Then she was diagnosed with breast cancer. Her treatment included surgery, chemotherapy, radiation, and multiple follow-ups. She hit her about $6,000 OOPM in February. The insurance paid everything else for the rest of the year – over about $200,000. She told me “I was terrified of the deductible, but it saved me in the end.”
That’s the trade-off. Low premium = high deductible/high OOPM. High premium = low deductible/low OOPM. Which one is better depends on how much healthcare you use.
The Health Plan Comparator can show you the breakeven point.
Now, let’s talk about prescription drugs. This is a huge gap that people miss. The SBC has a separate section for prescription coverage. Look for:
Formulary: the list of drugs covered. Is your medication on it? If not, you’ll pay more or it won’t be covered.
Tiers: generic (lowest cost), preferred brand, non-preferred brand, specialty (highest cost). Some plans have a separate deductible for drugs.
Mail order: some plans offer 90-day supplies for lower copays.
Step therapy: you may need to try cheaper drugs before they cover the expensive one.
I had a client – let’s call him Steve – who had asthma. He switched to a plan with a lower premium. He didn’t check the formulary. His inhaler wasn’t covered. The out-of-pocket cost was about $400 a month. He had to pay that for a year until open enrollment. He could have spent about $200 more on his premium to get a plan that covered his inhaler for $40. He learned the hard way.
Another thing people miss: the difference between HMO, PPO, and EPO.
HMO: You must have a primary care physician (PCP) and get referrals to see specialists. No out-of-network coverage except emergencies. Lowest premiums, narrowest networks.
PPO: You can see any provider without a referral. In-network costs are lower. Out-of-network is covered but with higher cost-sharing. Higher premiums, wider networks.
EPO: Like an HMO but without referrals. No out-of-network coverage except emergencies. Mid-range premiums.
If you have a preferred doctor or hospital, call them and ask which plans they accept. Do not rely on the plan’s online directory – I’ve seen directories that are months out of date. Call.
The Coverage Gap Calculator includes a health insurance section that flags these exact issues.
Now, let me give you a step-by-step method for reading any Summary of Benefits.
Step one: find the “Covered Services” table. It’s usually a grid with columns for “what you pay” in-network and out-of-network.
Step two: locate your deductible, coinsurance, copays, and out-of-pocket max. Write them down on a sticky note.
Step three: check the prescription drug section. Is your medication on the formulary? What tier? Any restrictions?
Step four: look for exclusions. Maternity? Mental health? Chiropractic? Acupuncture? Some plans exclude services you might need.
Step five: if you have a choice between plans, run the Health Plan Comparator. Input your expected healthcare use. See which plan costs less total.
I remember a couple – let’s call them the Parkers – who were both self-employed. They were choosing between a bronze HSA-eligible plan and a gold PPO. The bronze had a about $6,000 deductible per person, $12,000 family OOPM. Premium about $800 a month. The gold had a about $1,500 deductible per person, about $6,000 OOPM. Premium about $1,400 a month. They were healthy, so they picked bronze. Six months later, one of them had appendicitis. Hospital bill about $45,000. They paid their about $6,000 deductible, then coinsurance until they hit $12,000 OOPM. Total cost for the year: premiums $9,600 + out-of-pocket $12,000 = about $21,600. If they had chosen gold, premiums about $16,800 + out-of-pocket about $6,000 = about $22,800. Bronze was slightly cheaper. They made the right choice – but they didn’t know it until after the emergency.
The point is, you can’t predict the future. But you can plan for the range of possibilities.
Here’s my recommendation for most people under 60 who are generally healthy: a high-deductible health plan with an HSA. You pay lower premiums. You get a tax-advantaged savings account. You can invest the HSA funds. If you stay healthy, you build wealth. If you get sick, you have a high OOPM but your HSA covers it. The HSA is triple-tax-free: contributions are pre-tax, growth is tax-free, withdrawals for medical expenses are tax-free. It’s the best retirement account nobody talks about.
But if you have a chronic condition, take expensive medications, or expect a surgery in the next year, a low-deductible plan may be better. Run the numbers.
One more thing. Open enrollment is not the only time you can change plans. Certain life events – marriage, divorce, birth of a child, loss of other coverage, moving to a new area – trigger special enrollment periods. You usually have 60 days to enroll after the event. Don’t miss that window.
I’ll leave you with this. Health insurance is complicated on purpose. But the core is simple: premium, deductible, coinsurance, copay, OOPM, network. Master those six terms, and you can read any plan.
P.S. My sister – the one with the 180-page document – she ended up picking a PPO plan with a moderate premium and a low deductible because she has kids who get sick often. She used the Health Plan Comparator and realized that the lowest-premium plan would have cost her more in co-pays for sick visits. She said “I’m glad I didn’t just pick what looked cheapest.” That’s the win.
