L810 - Skin darkening that occurs after inflammation or injury heals

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

Postinflammatory hyperpigmentation is a common condition where areas of skin become darker than the surrounding skin after inflammation, injury, or irritation has healed. This darkening occurs because the inflammatory process triggers increased melanin (pigment) production in the affected area. The dark spots or patches are typically flat and can range from light brown to black in color. This condition is more common in people with darker skin tones and can result from various causes including acne, eczema, cuts, burns, or other skin trauma.

Additional Information

This is a benign cosmetic condition that may fade over time but can be persistent. Treatment options vary and may include topical lightening agents, chemical peels, or laser therapy depending on severity and patient preference.
