What does someone in medical billing and coding do?
Medical coding is the coding of each patient's diagnosis with an
ICD-9 code, which is a code number that is recognized world wide.
An ICD-9 (International Classification of Diseases, 9th Edition)
book contains a diagnosis code for every illness, disease, injury,
etc. known to man, and is used world wide.
Medical billing is the process of billing the medical companies,
using the transcribed medical information and the diagnosis codes,
to give the insurance companies all of the pertinent data required
to process payment of medical services.
