ICD-10 Code L65 – Other nonscarring hair loss (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L65 – Other nonscarring hair loss
What it is
L65 identifies hair loss without scarring of the scalp or other skin. Use it when the record describes nonscarring alopecia but does not name a more specific type.
Clinical signs
Typical findings include visible thinning, shedding, or patchy loss of hair with preserved skin surface. Clinical features vary; refer to documentation.
When to use this code
Use L65 when the clinician documents nonscarring hair loss and no more specific diagnosis is available. It also fits cases where the note says alopecia, hair thinning, or diffuse hair loss without scarring. If the type is specified, code that diagnosis instead.
Do not use for
Do not use L65 for scarring alopecia or hair loss tied to a different coded condition when the record supports a more specific code. Check documentation.
Coding tip
Capture the exact wording in the note and code the most specific nonscarring alopecia documented.
