Question: what does coinsurance subject to deductible mean?
Answer: Coinsurance. The percentage of costs of a covered health care service you pay (20%, for example) after you've paid your deductible. ... If you've paid your deductible: You pay 20% of $100, or $20. The insurance company pays the rest. If you haven't met your deductible: You pay the full allowed amount, $100.
