L80-L99: Other disorders of the skin and subcutaneous tissue
L98: Other disorders of skin and subcutaneous tissue, not elsewhere classified
The group of conditions classified under 'Other disorders of skin and subcutaneous tissue, not elsewhere classified' encompass a range of diverse conditions that generally affect the skin and underlying fatty tissue. These conditions can be either congenital or acquired, such as abnormal tissue growths, inflammatory and infectious conditions that do not fit into other classifications. They are typically distinguished by atypical presentations on the skin, like changes in color, texture, or thickness, which could be accompanied by symptoms such as itchiness, pain, or swelling. The disorders may fluctuate in severity and can either progress slowly or rapidly, depending on the underlying cause. These conditions can result from numerous factors, including immunological disorders, infections, genetic factors, or environmental triggers. The affected systems are generally confined to the integumentary system, which includes the skin and associated structures.
