ICD-10 Code L60.0 – Ingrowing nail (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L60.0 – Ingrowing nail
What it is
L60.0 identifies an ingrowing nail, usually when the nail edge grows into the surrounding skin. It commonly affects the big toe and may cause local irritation or inflammation.
Clinical signs
Typical findings include pain along the nail margin, redness, swelling, and tenderness. Clinical features vary; refer to documentation if the record does not clearly describe nail-edge involvement.
When to use this code
Use L60.0 when the clinician documents an ingrown or ingrowing nail, with or without mild local inflammation. It fits outpatient, urgent care, or podiatry notes when the diagnosis is explicit. If the note only says toe pain or infection, check documentation before assigning this code.
Do not use for
Do not use this code for generalized nail disorders, trauma without nail ingrowth, or unrelated toe infections. If the chart does not confirm an ingrowing nail, check documentation.
Coding tip
Code L60.0 only when the provider clearly links symptoms to nail ingrowth, not just pain or redness around the toe.
