Why must the superbill from the health care provider include a CPT or procedure code?

Your health insurance company uses CPT codes as a standardized way to identify the services you received, determine whether they’re covered under your plan, and process your claim for reimbursement. It’s important that your provider uses the correct code to properly reimburse you for your visit. Developed by the American Medical Association, CPT terminology is the most widely accepted medical coding system in the United States, used across both public and private insurance programs.
