In the abet on 1900s, it was realized that in order to cope subsequent to than maintaining medical records of patients and payments by insurance companies for medical expenses, a unified coding system was required to be developed. Medical insurance companies were finding it increasingly difficult to gloss making every other payments to two or more patients who had contacted the same disease and been through the same procedure.
The health industry realized that there was an urgent compulsion to build a standardized method of tracking patients’ diagnosis, procedure or treatment. This would next find the maintenance for uniform standards for billing insurance companies for health facilities. Asides from this medical coding could be used for a variety of applications in health care, medicine and medical recommendation. These insert:
– Statistical analysis of diseases
– Help in decision maintain systems
– Ability to admission and monitor epidemic outbreaks.
There are two main classifications of medical coding, which are statistical and nomenclature. In statistical coding, same clinical concepts are grouped together into categories. The excuse for undertaking this is appropriately as not to make them too voluminous. Statistical coding also has an ‘others’ or ‘unsigned’ category for conditions that cannot be classified in the specified categories. In nomenclature coding, which is the one most commonly used in medical coding, there is a surgically remove code for all clinical concept. These medical codes are grouped into:
– Diagnostic codes
– Procedural codes
– Pharmaceutical codes
– Topographical codes
Diagnostic codes: In health care diagnostic codes are used to identify and organization diseases, disorders, symptoms, human entry patterns, and medical signs. There is no single take drive code and each code is assigned for a favorable mean. The codes are revised gone additional knowledge is attained.
Procedural codes: these are numeric or alphanumeric codes that are used to identify specific medical events taken by medical professionals.
Pharmaceutical codes: These codes are assigned to uniquely identify medications. There are several coding systems used worldwide.
Topographical codes: In medicine, topographical codes are used to identify a specific location in the human body.

In the United States the American Medical Association have developed their own medical coding systems and patients can use these codes to determine their diagnosis and treatment and along with to check their billing from the health assist provider or payments conventional from the insurers. The World Health Organization maintains several sets of international classifications that gain in facilitating comparing of health joined data. Some countries have adapted and are using these systems for their own health care systems.
