Coinsurance (Health Insurance)
Insurance Glossary
The percentage of a covered medical bill a patient pays after meeting the deductible, such as 20 percent of the allowed amount with the plan paying the remaining 80. It differs from a copay, which is a fixed dollar amount rather than a share, and it continues until the out-of-pocket maximum is reached, after which the plan pays covered care in full. The same word means something different in property insurance, where it is a condition requiring a building to be insured to a stated percentage of its replacement cost.
