What is medical classification and what is medical coding? Well, both the terms refer to the process of transforming details of medical diagnostic processes and diagnosis into medical code numbers that are universal. The four basic categories of coding are diagnostic codes, procedural codes, pharmaceutical codes, and topographical codes. The diagnostic codes are used to group and identify diseases, disorders, symptoms, and medical signs, and the procedure codes are numbers or alphanumeric codes used to identify specific health interventions that are taken by medical professionals. While the pharmaceutical codes are about medications the topographical codes indicate the concerned body part.
From where are all these details about the patient's disease and his medical history taken? Some of the sources include,
Doctor's notes
Biochemistry Lab reports
Radiology reports
What is the use of these medical codes? They are used to track diseases and quite useful for health insurance companies, government hospitals, worker's compensation carriers etc. These medical coding/ classification system applications are mainly used for reimbursements of the medical bills from insurance companies. It is also used for statistical analysis, in epidemic surveillance and for knowledge based decision support.
