Systematized Nomenclature of Medicine

The Systematized Nomenclature of Medicine (SNOMED) is a multiaxial, hierarchical classification system. As in any such system, a disease may be located in a body organ which results in a code in a topography axis and may lead to morphological alterations represented by a morphology code..

Axes

There are 11 axes. The axes and some examples are provided below:

T (Topography) -- Anatomic terms

* (T-28000) Lung
* (T-32000) Heart
* (T-51000) Mouth
* (T-D2500) Hip
* (T-D9600) Heel

M (Morphology) -- Changes found in cells, tissues and organs M (Morphology) -- Changes found in 0

* (M-40000) Inflammation
* (M-44000) Granuloma
* (M-54700) Infarcted
* (M-54701) Microscopic infarct

"For the Morphology axis, SNOMED has [http://www.snomed.org/clinical/anatomic.html agreed] to use the same codes defined by International Classification of Diseases for Oncology. Additional examples on topology are provided on that page."

L (Living organisms) -- Bacteria and viruses

* (L-21801) Mycobacterium tuberculosis
* (L-25116) Streptococcus pneumoniae

C (Chemical) -- Drugs

* (C-C137A) Bufferin Analgesic Tablets
* (C-C137B) Bufferin Analgesic Caplets

F (Function) -- Signs and symptoms

* (F-03003) Fever

= J (Occupation) -- Terms that describe the occupation=

BUSINESSMAN
SCHOOL TEACHER
COMPUTER PROGRAMMER
DOCTOR
NURSE
BEAUTICIAN

D (Diagnosis) -- Diagnostic terms

* (D-13510) Pneumococcal pneumonia
* (D-14800) Tuberculosis
* (D3-15000) Myocardial infarction

P (Procedure) -- Administrative, diagnostic and therapeutic procedures

A (Physical agents, forces, activities) -- Devices and activities associated with the disease

S (Social context) -- Social conditions and important relationships in medicine

* (S-10120) Mother

G (General) -- Syntactic linkages and qualifiers
