R20-R23: Symptoms and signs involving the skin and subcutaneous tissue

R23: Other skin changes

Other skin changes, grouped under ICD-10 code R23, represent a variety of skin conditions that generally show visible, physical alterations on the skin. These changes can range from abnormal pigmentation, paleness or redness, to unexpected growths or structural deformities. Causes may span a wide range that includes environmental triggers, such as prolonged exposure to sunlight or cold, and internal factors like hormonal imbalances, autoimmune diseases, or genetic malformations. The common symptoms of these conditions might involve variations in skin color or texture, pain, itchiness, or even alterations in hair or nail growth. The progression, severity, and the specific body system affected can vary greatly depending on the individual condition within this group. Therefore, the accurate diagnosis and understanding of these other skin changes often require professional medical investigations.
