ICD-10 Code L60 – Nail disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L60 – Nail disorders
What it is
L60 is the ICD-10-CM code for disorders of the nails. Use it for conditions affecting the fingernails or toenails when the documentation does not support a more specific nail diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include nail discoloration, thickening, brittleness, ridging, splitting, or abnormal nail shape.
When to use this code
Use L60 when the provider documents a nonspecific nail disorder and does not identify a more detailed condition. It is also appropriate when the note describes nail abnormalities without a clear etiology. Check documentation if the record suggests trauma, infection, or skin disease.
Do not use for
Do not use L60 when a more specific nail diagnosis is documented, such as nail dystrophy due to another condition. Do not use it for isolated skin, toe, or finger disorders that are not nail-related.
Coding tip
If the note names the cause or type of nail problem, code the more specific diagnosis instead of L60.
