Also known as an encounter form, route slip or fee slip. This is a paper charge capture tool used to document coding for a specific patient visit. It is a printed form with patient information at the top, and a subset of the provider's/practice's most commonly used ICD and/or CPT codes. The form travels with the patient through the clinic. Providers check off items when they see the patient, and the form then travels to the checkout desk or billing office where the codes are entered into the billing system.
