L918 - Other skin conditions causing abnormal thickening or overgrowth of skin tissue

International Classification of Diseases

Last updated: 10/3/2025

What is a ICD-10 Code?

ICD-10 (International Classification of Diseases, 10th Revision) codes are used to classify and code all diagnoses, symptoms, and procedures recorded in association with hospital care. These codes provide a standardized way to track health conditions and their treatment outcomes.

Detailed Description

This code refers to various skin conditions that cause the skin to become abnormally thick, raised, or overgrown, but don't fit into more specific categories of hypertrophic (overgrowth) skin disorders. These conditions involve an excess production of skin cells or tissue, resulting in areas of thickened, raised, or enlarged skin. Examples might include certain types of scars, skin tags, or other benign skin growths. The exact condition would depend on your specific diagnosis and examination findings. These are typically non-cancerous conditions, though proper medical evaluation is important for accurate diagnosis and appropriate treatment.

Additional Information

This is a general category code - your specific condition may have different characteristics and treatment options. Most hypertrophic skin disorders are benign but should be evaluated by a healthcare professional for proper diagnosis and management.
