ICD-10 Code L60.5 – Yellow Nail Syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L60.5 – Yellow nail syndrome
What it is
Yellow nail syndrome is an uncommon disorder that affects the nails and may also involve swelling and respiratory problems. You use this code when the documentation specifically identifies this syndrome.
Clinical signs
Typical findings include slow-growing, thickened, yellow nails, often with absent cuticle or nail curvature changes. Clinical features vary; refer to documentation.
When to use this code
Use L60.5 when the provider documents yellow nail syndrome as the diagnosis, whether based on nail changes alone or with associated systemic findings. It may appear in specialty notes such as dermatology or pulmonology. If the record only describes yellow nails without the syndrome, check documentation.
Do not use for
Do not use this code for nonspecific nail discoloration, fungal nail disease, or other isolated nail disorders unless yellow nail syndrome is documented. Check documentation.
Coding tip
Confirm that the word “syndrome” appears in the assessment or impression before assigning L60.5.
