Total cost is what matters
A plan with a $300/month premium and $5,000 deductible costs $3,600 + actual medical use.
A plan with a $600/month premium and $1,000 deductible costs $7,200 + actual medical use.
Below ~$3,000 of medical use, plan A wins. Above, plan B catches up. Above max OOP, plan A wins again. The break-even depends on your actual use.
The HDHP + HSA stack
If you pick an HSA-eligible HDHP and contribute the max to an HSA, you get: tax deduction now, tax-free growth, tax-free withdrawal for medical.
That stack often makes HDHP cheaper than PPO even at moderate medical usage.
Especially valuable for high earners and those who can pay medical expenses from cash flow and let the HSA compound.
The network trap
The biggest hidden cost in health insurance is going out-of-network for one specialist or hospital.
A $500 in-network procedure can be $5,000 out-of-network at the same facility — same care, different billing code.
Before any non-emergency procedure, confirm in-network status of every provider involved (surgeon, anesthesiologist, hospital, lab).
Open-enrollment strategy
Look at last year's actual medical spending — pull from your EOBs.
Pick a plan that minimizes your total expected cost: premium + likely OOP.
Factor in HSA tax savings if eligible.
Stress-test: what if a major event hits? Your max-OOP exposure should be sustainable.
Common health-insurance mistakes
- Choosing the plan with the lowest premium without modeling expected use.
- Not maxing the HSA when eligible.
- Going out-of-network without verifying coverage.
- Skipping insurance entirely to "save money."
- Letting FSA funds expire unused.
