When navigating health insurance policies, terms like *coinsurance* can be confusing. One common coinsurance arrangement is the 80/20 rule, which determines how medical costs are shared between you and your insurer. Understanding this rule can help you budget for healthcare expenses and avoid unexpected bills.

What Is Coinsurance?

Coinsurance is the percentage of medical costs you pay after meeting your deductible. Unlike a copay (a fixed fee per service), coinsurance is a percentage split between you and your insurance company.

How the 80/20 Rule Works

Under an 80/20 coinsurance plan:

of covered medical expenses.

out of pocket.

Example Scenario:

Suppose you have a ,000 medical bill after meeting your deductible.

0 (80% of ,000)

0 (20% of ,000)

This split continues until you reach your out-of-pocket maximum, after which the insurer covers 100% of eligible costs.

Key Considerations

Coinsurance only applies *after* you’ve met your annual deductible.

The 80/20 split typically applies to in-network providers. Out-of-network care may have higher coinsurance (e.g., 50/50).

Once you hit this limit, your insurer covers all remaining eligible expenses for the year.

Why the 80/20 Split?

This structure balances cost-sharing:

(since you share costs).

(thanks to the out-of-pocket cap).

Final Thoughts

The 80/20 coinsurance rule simplifies cost-sharing between you and your insurer. Always review your policy details, including deductibles and network restrictions, to avoid surprises. By understanding how coinsurance works, you can make informed healthcare decisions and manage expenses effectively.
