Ultimately, although the purpose of a hospital is to heal and care for the well-being of its patients, a hospital is still a business. Patientcharge labels provide a means of keeping track of the costs of taking care of a patient. Patient charge labels are removed from products and added to a patients chart. When it comes time to discharge a patient, these patient charge labels are used to transfer information on a patients usage to a billing system. Patient charge labels also help keep track of a hospitals inventory. When so many charges for a certain product are entered into a billing system, the purchasing department knows that they must reorder the product. These patient charge labels can inform the purchasing department of where products must be delivered within the hospital. Patient charge labels can come in roll or sheet form. Additionally, varying colors and sizes are available.
