In which reimbursement method does a provider bill the patient if they want to charge more than the allowable rate?

The reimbursement method where a provider can bill the patient if they want to charge more than the allowable rate is discounted fee-for-service. In this model, healthcare providers typically negotiate discounted rates with insurance companies for the services they provide. However, if the provider's charge exceeds the agreed-upon discounted rate, they have the option to bill the patient for the difference.

In fee-for-service, while providers bill for the individual services rendered, they usually do not charge patients above the allowable rate set by the insurance plan. Capitation involves a per-member payment regardless of the number of services provided and does not allow for additional billing based on charges. Global payment encompasses a fixed amount for an episode of care, which also restricts charging more than the set rate. Thus, discounted fee-for-service is the correct answer as it provides flexibility for providers to bill patients beyond the insurance reimbursement rate.
