Coinsurance – A form of medical cost sharing in a health insurance plan that requires an
insured person to pay a stated percentage of medical expenses after the deductible
amount, if any, was paid.
Â¨ Once any deductible amount and coinsurance are paid, the insurer is responsible
for the rest of the reimbursement for covered benefits up to allowed charges: the
individual could also be responsible for any charges in excess of what the insurer
determines to be â€œusual, customary and reasonableâ€.
Â¨ Coinsurance rates may differ if services are received from an approved provider
(i.e., a provider with whom the insurer has a contract or an agreement specifying
payment levels and other contract requirements) or if received by providers not
on the approved list.
Â¨ In addition to overall coinsurance rates, rates may also differ for different types
Co-payment – A form of medical cost sharing in a health insurance plan that requires an
insured person to pay a fixed dollar amount when a medical service is received. The
insurer is responsible for the rest of the reimbursement.
Â¨ There may be separate co-payments for different services.
Â¨ Some plans require that a deductible first be met for some specific services
before a co-payment applies.
Deductible – A fixed dollar amount during the benefit period – usually a year – that an
insured person pays before the insurer starts to make payments for covered medical
services. Plans may have both per individual and family deductibles.
Â¨ Some plans may have separate deductibles for specific services. For example, a
plan may have a hospitalization deductible per admission.
Â¨ Deductibles may differ if services are received from an approved provider or if
received from providers not on the approved list.
