5 Mistakes to Avoid When Picking Health Insurance
Most health insurance regret traces back to one of five mistakes. They're easy to make. They're also easy to avoid if someone walks you through what to look for.
Here are the five we see most often, and how to dodge each one.
Mistake 1: Comparing on monthly premium alone
The single most expensive mistake people make is treating premium as the comparison.
A $180/month plan with a $10,000 deductible isn't actually cheaper than a $340/month plan with a $2,500 deductible — if you're going to use the plan. The honest comparison is total annual cost: premium plus deductible plus expected out-of-pocket.
Run the math both ways:
- Best case (you don't use it much): Annual premium + small out-of-pocket
- Average case (a few visits, prescriptions): Annual premium + estimated mid-range OOP
- Worst case (a hospitalization or major event): Annual premium + OOP maximum
A $180/month plan with $10K deductible has a worst case of $2,160 + $10,000 = $12,160. A $340/month plan with $2,500 deductible has a worst case of $4,080 + $2,500 = $6,580. The "cheaper" plan is dramatically more expensive in the worst case.
Pick based on your realistic usage and your worst-case tolerance, not the headline number.
Mistake 2: Assuming your doctor is in-network
Networks change every year. Doctors leave networks. Hospitals merge and re-contract. The plan that covered your primary care last year may not cover them this year — or may have moved them to a different tier.
Before enrolling in any networked plan (ACA, TriTerm, HealthBridge PPO):
- Get the plan's full network name. Not just "HealthBridge" — specifically "Aetna Open Choice PPO" or "Cigna PPO" or "UHC Choice Plus" etc.
- Check each doctor on the carrier's provider directory. Or call the carrier directly with the doctor's name and NPI.
- Check your hospital. Sometimes the doctor is in-network but the hospital they admit to isn't. That's a billing mess.
- Check anesthesiologists if you have a planned procedure. This is the classic surprise-billing scenario.
For fixed-benefit plans (HPG, Health Access), networks don't apply — you can use any provider, and the plan pays the same stated amount regardless.
Mistake 3: Buying short-term when ACA fits better (or vice versa)
The two products serve different needs. Confusing them costs money.
Short-term (TriTerm, HealthBridge PPO) usually fits when:
- You're healthy, clear underwriting cleanly
- Your gap is defined (a few months to ~3 years)
- You don't qualify for meaningful ACA subsidies
- You don't need maternity, mental health, or chronic-condition coverage
Compliance reminders:
- TriTerm: Short-term limited-duration medical. Medically underwritten. Preexisting conditions not covered in first 12 months. Not ACA-compliant.
- HealthBridge STM PPO: Short-term medical insurance. Medically underwritten. Preexisting conditions not covered in first 12 months (may be covered after 12 months with Renewable option). Not ACA-compliant.
ACA usually fits when:
- Your projected income lands in the subsidy zone for Premium Tax Credits
- You have a preexisting condition that needs ongoing care
- You're pregnant or planning a pregnancy
- You take expensive prescriptions
- You don't yet know how long the gap will be
The mistake we see most: people in the second bucket buying short-term because the premium looks better, then getting blindsided when the preexisting condition exclusion bites in month 3.

Mistake 4: Confusing fixed indemnity with major medical
Fixed indemnity plans (HPG, Health Access) pay stated dollar amounts per covered service. Major medical plans (ACA, TriTerm, HealthBridge PPO) cover percentages of actual costs after deductible.
These are fundamentally different products. They get sold side-by-side, often by brokers who blur the difference because the fixed indemnity premium looks cheaper.
Compliance reminders:
- HPG: Fixed indemnity plan. Pays stated benefit amounts per covered service. Not a substitute for major medical / ACA coverage.
- Health Access: Fixed-benefit medical plan. Pays stated benefit amounts per covered service. Not a substitute for major medical / ACA coverage. No annual or lifetime maximums.
The difference matters because:
- Fixed indemnity has no out-of-pocket maximum. A $200K medical event leaves you exposed above the stated benefits.
- Major medical has an OOP cap. Once you hit it, the plan covers 100% for the rest of the year.
Fixed indemnity has its place — predictable per-event payouts, no network restrictions, supplemental layer on top of HDHPs. But it's not a substitute for catastrophic-risk protection.
If a broker pitches fixed indemnity without explaining the catastrophic-risk gap, ask: "What happens if I have a $300,000 hospital bill on this plan?" The honest answer is "you owe most of it." Make sure you hear that answer before you enroll.
Mistake 5: Not running the ACA subsidy math because "I make too much"
This one applies to higher earners and self-employed people, and it's costing households thousands per year.
ACA Premium Tax Credit subsidies are calculated on Modified Adjusted Gross Income (MAGI) — your taxable income with adjustments. For self-employed people, MAGI is calculated after legitimate business deductions, SEP-IRA contributions, and the self-employed health insurance deduction itself.
Common scenarios where people assume they don't qualify but actually might:
- Self-employed grossing $120K but with $25K of legitimate deductions and a $7K SEP-IRA contribution → MAGI ~$88K
- Couple with one W-2 income at $135K and one staying-home parent → household of 4 at 400-500% FPL
- Recently divorced parent with custody filing as head-of-household → income that would've been below the cliff for the household before but isn't anymore
For 2021-2025, expanded subsidies meant even higher-income households often qualified. For 2026, the rules are tightening — but the math still surprises people.
Run the marketplace's "preview plans" tool with your projected MAGI and household size before assuming you don't qualify. Or have a broker run it. Takes 5 minutes.
Bonus: The mistake-of-omission
Not asking what happens if your situation changes mid-year.
Plans differ in how they handle:
- Income changes (ACA: update marketplace; private: not relevant unless it triggers an SEP)
- Move to a new state (ACA: SEP triggered if benchmark plan changes; private: state availability matters)
- New baby (ACA: SEP, baby covered from birth; private: doesn't apply, baby would need ACA SEP)
- Job change with new coverage (ACA: cancel marketplace; private: cancel and prorated refund)
Ask before you enroll. The plan that fits today may not fit your situation in 6 months — knowing the off-ramp matters.
What to bring to the conversation
A good broker conversation moves fast if you bring:
- Projected 2026 MAGI (or current household income for short-term shopping)
- Household size and ages
- Tobacco status
- Medications list
- Health conditions and recent procedures
- Specific providers you want to keep
- Coverage gap timeline (how long until something else is in place, if applicable)
- ZIP code and state
That's enough to run subsidy math and pull plan options across all five carriers we work with. We don't need an SSN or full intake until you're ready to enroll.
FAQ (FAQPage schema)
Q · How do I know if my doctor is in-network?
Get the plan's specific network name (e.g., "Aetna Open Choice PPO" not just "HealthBridge") and check the carrier's provider directory or call the carrier with the doctor's name. Confirm the hospital is also in-network if you have planned procedures.
Q · What's the difference between fixed indemnity and major medical?
Fixed indemnity pays stated dollar amounts per covered service with no out-of-pocket maximum. Major medical covers percentages of actual costs after deductible, with an OOP cap. They serve different purposes — fixed indemnity is predictable for everyday care; major medical is catastrophic-risk protection.
Q · When should I run ACA subsidy math?
Always, before assuming anything. Many higher-income and self-employed households qualify for subsidies they don't expect, especially after legitimate business deductions and household-size factors apply. Takes 5 minutes; can change the entire comparison.
