Medical coding is the process of translating healthcare diagnoses, procedures, medical services, and equipment into universal medical alphanumeric codes. These codes are used for billing, insurance claims, and maintaining accurate medical records. Medical coding professionals use classification systems such as ICD-10, CPT, and HCPCS to ensure accuracy and compliance in the healthcare industry[1][2].
As healthcare systems become increasingly complex, the need for precise and standardized coding has grown. Accurate medical coding helps healthcare providers receive timely reimbursement, reduces insurance claim denials, and improves patient care documentation. Medical coding blends clinical knowledge with administrative expertise, making it a critical component of healthcare operations[1][3].
