International statistical classification

International statistical classification of disease and relative problems of Health Protection are present of for successful international collaboration in Public Health, by understanding between doctors from all countries. It is revised each 10 years by the International organization of Public Health. Last 10-th revision was in 1993.

Classifications have a class, groups, rubric; each disease has cod from 3 digits.

 

I.C.D.-10:

- Change ordinal number class of disease.

- In a separate class pick out disease of organs (ear, nose)

- Increase number classes from 17 to 21 (19 basic and 2 additional; 20 class- outside sickness rate and death;

- 21 – factors influencing conditions of a health of population and visited in institutions of health protection.

- Figure code.

- Alphabet – figures code; 1^st figure, means class must change on definite Latin alphabet (for example, class disease of endocrine systems designate with letter E.)
