International Classification of Diseases

Last updated: 3/24/2026

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

Actinic keratosis is a common skin condition that appears as rough, scaly, or crusty patches on areas of skin that have been damaged by long-term sun exposure. These patches are typically found on sun-exposed areas like the face, ears, neck, scalp, chest, backs of hands, forearms, or lips. The patches may be tan, pink, red, or the same color as your skin. While actinic keratoses are considered precancerous lesions, they can potentially develop into squamous cell carcinoma if left untreated.

Additional Information

This is a precancerous condition that requires medical attention and monitoring. Treatment options may include topical medications, cryotherapy, or other dermatological procedures as determined by a healthcare provider.
