Medical billing is the process of generating healthcare claims to submit to insurance companies for the purpose of obtaining payment for medical services rendered by providers and provider organizations. After translating a healthcare service into a billing claim, the medical biller follows the claim to ensure the organization receives reimbursement for the work the provider performed. A knowledgeable medical biller can optimize revenue performance for the physician practice or healthcare organization. Increasing reimbursement pressures within the healthcare industry have increased the need among provider organizations to hire highly trained, highly skilled medical billers. Professionals with an understanding of medical insurance, reimbursement methodologies, and the claims process are in high demand.
