Diagnoses are classified in 207 clinically relevant groups, related to specific organs (stomach, intestine, heart, etc.) and pathologies (infection, neoplasm, etc.), and classified by physiologic systems.

Diagnoses groups are coded using four characters.
The first character indicates the involved system:

B new-born

C circulatory

D digestive

E endocrine

F female

H hepatic

L locomotion

N nervous

O Ear, Nose, Throat (ORL)
P psychic

R respiratory

S blood

T tegument

U urinary tract

Y ocular (eye)

Z unspecified

The second character can be an indent (-) or a sign + meaning a severe condition.

The third character is a small letter, which refers to the nature of the pathology:

b benign neoplasms

d degeneration

f functional

I infection or inflammation

m malignant neoplasms

n neonatal

o occlusion

s ischemia

t traumatism

z other

Lastly, the fourth character is a capital letter which is generally the first letter of the affected organ in its Latin designation, e.g. D-mR means an malignant condition (m) of the digestive system (D) involving the rectum (R).

New born are classified by their birth weights (<1000 g, 1000-1550 g, etc.)
