ICD-10 Code L60.3 – Nail dystrophy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L60.3 – Nail dystrophy
What it is
L60.3 identifies dystrophic changes of the nails, meaning the nail is abnormally formed, brittle, thickened, ridged, or otherwise damaged. Use it when the documentation describes nail dystrophy without a more specific nail disorder.
Clinical signs
Findings may include nail thickening, splitting, crumbling, discoloration, ridging, or abnormal shape. Clinical features vary; refer to documentation.
When to use this code
Use L60.3 when the provider documents nail dystrophy as the diagnosis or describes nonspecific dystrophic nail changes. It also fits cases where the nail abnormality is chronic and no more precise nail condition is recorded.
If the note names a different nail disease, code that condition instead. Check documentation when the cause is unclear or when multiple nail disorders are mentioned.
Do not use for
Do not use this code for acute nail trauma, infection, or other clearly identified nail disorders. If the record supports a more specific diagnosis, code that condition instead.
Coding tip
Code from the provider’s exact wording and avoid assuming the cause of the nail change.
