Copayment (Copay)

A copayment, commonly called a copay, is a fixed dollar amount that a dental patient pays out of pocket for a specific service at the time of the visit. Unlike coinsurance, which is a percentage of the allowed amount that varies with the total cost of the procedure, a copay is a predetermined flat fee that remains the same regardless of what the provider charges. Copayments are most commonly associated with dental health maintenance organization plans and capitation-based arrangements, where each covered procedure has a fixed patient copay amount listed in the plan's copay schedule. PPO and indemnity plans typically use coinsurance percentages rather than copays, though some PPO plans include copays for specific services like office visits.

In DHMO plans, the copay schedule functions as the complete patient payment framework. The schedule lists every CDT procedure code along with the fixed dollar amount the patient owes for that service. Preventive procedures such as cleanings and exams often carry a zero-dollar copay, while basic procedures like fillings may range from $50 to $100 and major procedures like crowns may require copays of $200 to $500. The provider receives the capitation payment from the carrier plus the patient's copay as total compensation for the service. There is no deductible, coinsurance, or annual maximum in a traditional DHMO copay structure.

For dental practices, accurate copay collection requires the billing team to verify the exact copay schedule for each DHMO patient before treatment. Copay amounts can vary between plans from the same carrier and are subject to change at plan renewal. Collecting too little results in a balance due that is difficult to collect after the visit, while collecting too much requires a refund. Practices that treat a high volume of DHMO patients should maintain current copay schedules in their practice management system and train front desk staff to reference the correct schedule for each patient at check-in.
