Medical billing is an essential function in healthcare administration, where healthcare providers submit claims to insurance companies or patients for services rendered. This process involves coding medical procedures and diagnoses according to standardized coding systems, such as ICD-10, CPT, and HCPCS. Effective medical billing ensures that providers are reimbursed promptly and accurately, minimizing errors and claim denials. A well-executed billing system also supports cash flow management, enhances operational efficiency, and helps healthcare practices comply with regulations.
