Coinsurance

Definition

The percentage of a covered medical cost a patient pays after meeting the deductible. A 20% coinsurance plan with a $1,000 monthly Wegovy bill means the patient pays $200 and the insurer pays $800. Distinct from a copay (a fixed dollar amount). Coinsurance typically applies until the annual out-of-pocket maximum is reached.
