What Is Medical Billing?
Medical billing is the process of submitting and following up on claims with health insurance companies to receive payment for services provided by a healthcare provider. It’s the bridge between the medical provider and the insurance company.
This involves:
-
Translating medical procedures into standardized codes
-
Creating and submitting claims
-
Tracking payments and handling denials
-
Communicating with healthcare providers and insurance companies
Medical billing is often paired with medical coding, but they are distinct. Coding involves identifying the correct codes for diagnoses and treatments, while billing focuses on preparing and submitting claims for payment.
