The requirements will vary depending on the type of billing being done. Full name, date of birth, sex, physician, collection date and time, and tests being done must all be included on a requisition when a laboratory reference account or physician office will be billed. Please mark the box “Bill Account”. When a patient will be billed, all of the above information must be included as well as billing information (self-pay, insurance, Medicare/Medicaid), and the patient diagnosis. In addition, Microbiology, Cytology, and Histology requisitions all require the specimen type/source.
