WHATkind of health insurance involves a co-pay for doctor visits?

Health insurance plans that involve a co-pay for doctor visits typically include Health Maintenance Organizations (HMOs) and Preferred Provider Organizations (PPOs). In these plans, members pay a fixed amount, or co-pay, at the time of service for visits to primary care physicians or specialists. This structure helps to reduce out-of-pocket expenses for each visit while allowing for manageable healthcare access.
