Localized hypertrichosis

This code signifies an abnormal and excessive growth of hair in a specific, circumscribed area of the body, rather than generalized hirsutism. This localized hair growth is typically denser, coarser, or longer than the surrounding hair. It can occur congenitally or develop later in life due to various factors.

Use this code when documentation clearly indicates an overgrowth of hair confined to a particular region, such as a nevus, a scar, or a specific body part. This code is appropriate when the hypertrichosis is not systemic or diffuse. Supporting documentation should specify the localized nature of the hair growth.

• Differentiate from generalized hirsutism (R68.1) which implies widespread excessive hair growth, often hormonally driven.
• Consider coding any underlying cause or associated condition (e.g., congenital melanocytic nevus with hypertrichosis) as a primary diagnosis if applicable.
• Ensure the provider's documentation explicitly states "localized" or describes the specific area affected to justify this code.
