Medical billing is the process of converting healthcare services provided to a patient into insurance claims and ensuring that healthcare providers receive payment for those services. It serves as the bridge between patients, healthcare providers, and insurance companies, helping maintain a smooth financial workflow within the healthcare system.
Medical billers review patient information, verify insurance coverage, submit accurate claims, follow up on unpaid or denied claims, post payments, and collect any remaining patient responsibility. Their work ensures providers are reimbursed correctly while complying with healthcare regulations and payer guidelines.
