ICD-10 Code L60.9 – Nail disorder, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L60.9 – Nail disorder, unspecified
What it is
L60.9 identifies a nail problem that is documented but not further specified. Use it when the record confirms a nail disorder, yet the exact type is not named.
Clinical signs
Clinical features vary; refer to documentation. Common charted findings may include nail changes, deformity, discoloration, thickening, brittleness, or pain, but the record must support a nonspecific nail disorder.
When to use this code
Use this code when the provider documents a nail disorder without naming a more specific diagnosis. It is appropriate when the note says “nail disorder,” “nail abnormality,” or similar wording and no further detail is available.
If later documentation identifies a specific condition, you should code that more precise diagnosis instead. Check documentation for the affected nail, cause, and any associated skin or systemic disease.
Do not use for
Do not use L60.9 when the record supports a specific nail diagnosis, such as ingrown nail or fungal nail disease. Also avoid it if the finding is only a normal variant or unrelated skin condition.
Coding tip
Before assigning L60.9, look for a more specific nail diagnosis elsewhere in the note.
