L80-L99: Other disorders of the skin and subcutaneous tissue

The group of conditions labelled as 'Other disorders of the skin and subcutaneous tissue' encompass a wide range of dermatological issues that primarily affect the skin and the layer of fat just below it. This group includes diverse conditions such as vitiligo, where patches of skin lose their pigmentation, or scleroderma, a progressive disease that hardens and tightens the skin and connective tissues. Other disorders in this category might lead to changes in skin color or texture. Most of these conditions aren't contagious but they could be caused by genetic, environmental, or immune system factors. Symptoms vary significantly depending on the condition but may often involve changes in skin appearance, discomfort, or itchiness. While some of these diseases are progressive, meaning they get worse over time, others remain static or can even improve.
