Frequently Asked Questions
What is the difference between a Deductible and Out-of-Pocket Maximum?
A deductible is the initial amount you must pay 100% out-of-pocket before insurance covers a dime. The out-of-pocket maximum is the hard legal ceiling—once reached, your health insurer pays 100% of all covered in-network services for the rest of the plan year.
What is coinsurance?
Coinsurance is the percentage split of covered medical costs you pay after meeting your deductible (most commonly an 80/20 split, where insurance pays 80% and you pay 20%).
Does monthly premium count toward your deductible or out-of-pocket max?
No. Premiums are the ongoing monthly subscription cost to maintain coverage. They do not count toward your deductible or out-of-pocket maximum.
When does an HDHP beat a traditional PPO plan?
HDHPs beat PPOs in two scenarios: 1) Very low medical utilization (you pocket huge premium savings and HSA tax breaks), or 2) Catastrophic medical utilization (the lower annual premium plus capped OOP max results in lower all-in costs than high PPO premiums).
