ICD-10 Code L65.8 – Other specified nonscarring hair loss (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L65.8 – Other specified nonscarring hair loss
What it is
L65.8 identifies nonscarring hair loss that does not fit a more specific ICD-10 category. The hair follicles are not permanently destroyed, so regrowth may still be possible depending on the cause.
Clinical signs
Expect visible thinning, patchy loss, or diffuse shedding without scalp scarring. Clinical features vary; refer to documentation for the pattern, suspected cause, and whether the follicles remain intact.
When to use this code
Use L65.8 when the clinician documents a nonscarring alopecia that is not otherwise classified, such as an unusual or unspecified pattern. It is appropriate when the record clearly states “other specified” hair loss and does not support a more specific code.
Check documentation if the note only says “hair loss” or “alopecia” without further detail. Code the documented type when a specific nonscarring diagnosis is provided.
Do not use for
Do not use this code for scarring alopecia or hair loss with permanent follicle destruction. Also avoid it when the documentation supports a more specific nonscarring hair loss code.
Coding tip
Query for the exact alopecia type and whether it is scarring or nonscarring before assigning L65.8.
