Medical coding is a healthcare back-end process wherein medical coding specialist transforms healthcare diagnosis, procedures, and other healthcare services into universal alphanumeric medical codes.
These diagnostic/procedure codes are taken after abstracting data from electronic medical documents, for eg. transcribed physician charts/notes, lab results, x-ray imaging studies, etc.
Simply put, you need to convert medical documents into codes (the language medical insurance industry understands). First step in healthcare insurance billing is medical coding using CPT, HCPCS, ICD10, ICD9 codes.
Medical coding (like medical transcription) is an outsourced KPO jobs from US hospitals to Indian companies, which recruits Indian employees who work remotely for US hospitals/companies/insurance Industry after medical coding training and necessary certification.
