Acne Vulgaris - ICD 10

What is ICD 10?

ICD-10 is the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD).  ICD 10 is a medical classification list by the World Health Organization (WHO). It includes codes for diseases, signs and symptoms, abnormal findings, external causes of injury or diseases etc.

What is Acne?

Acne is a disorder of the pilo-sebaceous apparatus characterized by comedones, papules, pustules, cysts and scars.

Acne lesions develop from the sebaceous glands associated with hair follicles – commonly on the face, but also on external auditory meatus, back, chest, and anogenital area. (Sebaceous glands are also found on the eyelids and mucosa, prepuce and cervix, where they are not associated with hair follicles.) The sebaceous gland contains holocrine cells that secrete triglycerides, fatty acids, wax esters, and sterols as “sebum”. The main changes in acne are:

  1. Increase in sebum secretion
  2. Thickening of the keratin lining of the sebaceous duct, to produce blackheads or comedones—the colour of
    blackheads is due to melanin, not dirt
  3. Increase in Propionibacterium acnes bacteria in the duct
  4. Increase in free fatty acids
  5. Inflammation around the sebaceous gland, probably as a result of the release of bacterial enzymes.
