Understanding Your Health Insurance

1️⃣ Deductible

What you pay before insurance starts sharing costs. After you meet your deductible, you enter the coinsurance phase — where you and your insurer split the bill (often 80/20).

2️⃣ Coinsurance

Your share of costs after the deductible. A 20% coinsurance means you pay 20% of each bill and insurance pays 80% — until you hit your out-of-pocket maximum.

3️⃣ Out-of-Pocket Max

The safety net. Once you've paid this amount (deductible + coinsurance + copays), insurance covers 100% of covered services for the rest of the plan year.

📋 Example: $3,000 Deductible, 20% Coinsurance, $8,700 OOP Max

January: You go to the doctor. The visit costs $250. You haven't met your deductible yet, so you pay the full $250. Remaining deductible: $2,750.

March: You have an MRI that costs $3,000. The first $2,750 goes toward your remaining deductible (now met). The remaining $250 enters coinsurance — you pay 20% ($50) and insurance pays 80% ($200). Total you've paid toward OOP max: $3,050.

July: You have a surgery that costs $25,000. With 20% coinsurance, your share would be $5,000 — but your OOP max is $8,700 and you've already paid $3,050. So you pay $5,650 (hitting your OOP max), and insurance covers the rest. OOP max reached! Insurance now covers 100%.

September–December: Any covered care is 100% paid by insurance. You pay $0 for the rest of the year.
