Copayment (or Copay)

A fixed amount ($10, for example) you owe for a prescription or medical visit that is covered under your health plan, usually paid when you receive the service. For most plans, the copay phase of cost-sharing starts right away; the exception is Health Savings Account (HSA) plans for which you have to meet the deductible first. Copays do NOT count towards your deductible amount, but they DO count towards your out-of-pocket maximum.
