Medical billing and coding services are essential components of the healthcare revenue cycle, involving the accurate translation of patient diagnoses, treatments, and procedures into standardized codes (such as ICD-10, CPT, and HCPCS) and the submission of these coded claims to insurance companies for reimbursement. Medical coders ensure that every service provided is properly documented and coded, while medical billers handle the financial side by submitting claims, tracking payments, managing denials, and posting payments. Together, these services streamline the administrative workload, reduce claim rejections, ensure compliance with regulations like HIPAA, and help healthcare providers get paid accurately and promptly.
