Copay vs coinsurance
Two different forms of patient cost-sharing under an insurance plan. A copay is a fixed dollar amount the patient owes per visit regardless of the total allowed amount (for example, $30 per office visit). Coinsurance is a percentage of the allowed amount the patient owes after the deductible is met (for example, 20% of the $180 allowed amount). Both are collected from the patient, not from the payer.
Why this matters for your clinic
The distinction matters for your patient collections workflow. Copays are predictable and should be collected at the point of service. Coinsurance amounts depend on the allowed amount and cannot be precisely calculated until the claim is adjudicated, which means they are often billed after the fact. Point-of-service collection rates for coinsurance are lower than for copays because the amount is not known at check-in.
Your payer mix determines your overall patient responsibility exposure. High-deductible health plans (HDHPs) have replaced traditional copay plans in much of the commercial market. Under HDHPs, patients owe the full allowed amount until the deductible is met, which makes patient collections look more like consumer collections than traditional copay collection. Practices that have not updated their patient financial counseling and collections processes for HDHP prevalence are experiencing rising patient bad debt.
Deductible status at the time of service is a key eligibility check. Collecting a $30 copay from a patient who has not yet met their $2,500 deductible is an undercollection. A proper eligibility verification process checks deductible status and estimates patient responsibility at the time of scheduling so collections expectations can be set before the visit.
What good looks like
Timing matters: MGMA found that in 2024 practices collected 72% of copays at the time of service but only about 27% of other patient-due balances, and whatever is not collected at the visit gets harder to collect later. This is the financial case for investing in real-time eligibility verification and point-of-service collection training.
Example
A patient has a PPO plan with a $1,500 deductible and 20% coinsurance after the deductible. They come in for a visit in March (deductible not yet met). The allowed amount is $165. The patient owes $165 (the full allowed amount, applied to deductible). If the front desk only collects a $30 copay, the practice undercollects $135 at point of service and must bill the balance afterward, reducing the likelihood of full collection.
From Sorso
The split between patient responsibility collected at the point of service and billed afterward is worth watching on its own, and it almost always has room to improve. Pre-visit deductible verification and a point-of-service collection script are the fastest lever for moving that number.
