What does a provider complete during or just after a patient's visit to summarize their billing information?

During or just after a patient's visit, a provider typically completes a superbill, which is a detailed invoice that includes the services rendered, diagnosis codes, and procedure codes. This document serves as a summary of the visit and is used to facilitate billing and insurance claims. The provider may also update the patient's electronic health record (EHR) to reflect the services provided and any relevant notes for future reference.
