Coinsurance
Coinsurance is the percentage of covered medical costs a patient pays after meeting their deductible, with the insurer covering the remainder. Surgery centers calculate coinsurance during eligibility checks and patient estimates to collect accurate amounts and reduce post-service balances.
What is coinsurance?
Coinsurance is the share of covered medical costs that a patient is responsible for paying, expressed as a percentage, once their deductible has been met. The insurer pays the remaining percentage, so a plan with twenty percent coinsurance means the patient owes that portion of the allowed amount.
Unlike a flat copay, coinsurance scales with the cost of the service, so larger or more expensive procedures generate larger patient obligations. It applies on top of, and only after, the deductible has been satisfied.
Why does coinsurance matter in the revenue cycle?
Coinsurance is a meaningful piece of what a patient personally owes, and getting it wrong leads to inaccurate estimates and uncollected balances after service. Calculating it correctly is therefore central to clean financial counseling and collections.
For an ambulatory surgery center, staff typically determine coinsurance during eligibility and benefits verification so the patient can be given an accurate cost estimate before the procedure. Collecting the right amount up front reduces the post-service balances that are difficult and expensive to chase later.
