What is a copay?
A copay is a fixed dollar amount you pay for certain services, like an office visit or a prescription. For example, you might pay $30 for a primary care visit or $50 for a specialist visit, regardless of the total bill. Copays are predictable per visit, but they are typically associated with plans with higher premiums. Copays often do not count toward your deductibleThe amount of medical bills you need to pay in a year before insurance starts splitting the bills with you., but they do typically count toward your out of pocket maxThe most you pay for covered medical bills in a year. After this, insurance pays 100% of covered costs.. Plan rules vary.
What is coinsurance?
Coinsurance is a set percentage of the medical bill you pay after you reach your deductible. For example, if your coinsurance is 20% and the allowed hospital bill is $5,000, you would pay $1,000 and your plan would cover the remaining $4,000. Coinsurance payments typically count toward the out-of-pocket max.
Copay vs coinsurance: what is the difference?
A copay is a fixed cost for a service. Coinsurance is a fixed percentage of the bill after you meet your deductible.
Example: a routine care year
If most of your care is routine visits and basic prescriptions, a copay plan can feel cheaper at the point of care because you pay fixed amounts. However, if the copay plan has meaningfully higher premiums, total annual cost can still be higher even when individual visits are cheap.
Example: an expensive care year
If you have expensive care, coinsurance becomes a bigger driver after the deductible. In that range, the out-of-pocket max and the premium difference often matter more than whether a plan uses copays or coinsurance. Two plans can end up closer than expected once spending approaches the out of pocket max.
