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 is the financial backbone of every medical practice — without accurate billing, providers cannot get paid for the care they deliver.

What Is Medical Billing?

Medical billing translates healthcare services into billing claims. When a patient visits a doctor, services are documented in medical records. A medical biller converts those records into a standardized claim and submits it to the insurance company for reimbursement.

The Medical Billing Process — Step by Step

Common Medical Billing Challenges

• Eligibility errors — patient insurance not verified before the visit
• Incorrect or missing diagnosis codes causing automatic denials
• Wrong modifiers applied to procedures
• Missing prior authorizations before services are rendered
• Timely filing deadlines missed — claims become uncollectable
• Underpayments from insurance not caught or appealed
• High patient balance write-offs due to poor collection processes
