Medical Insurance Billing and Coding is the process of translating patient care into standardized codes so healthcare providers can legally and accurately get paid—and medical coders are the specialists who make that translation precise and compliant.
When a patient sees a doctor, a lot happens clinically—but insurance companies don’t speak “doctor”. They speak codes.
Medical coders turn what the provider did (exam, test, surgery, diagnosis) into standardized codes.
Medical billers use those codes to create and submit claims so the provider gets paid.
No coding → no billing
Bad coding → delayed payment, denials, audits, or fraud risk
