Nail disorders (L60) ICD-10-CM
The L60 code range covers nail disorders with 9 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the L60 range.
Horizontal Nail Ridging
Linear transverse/horizontal groove of one or more nail plates that migrate distally from the proximal nail fold with nail growth, usually secondary to illness, trauma or malnutrition.
Nail Changes
Alteration of the normal characteristics of the fingernails or toenails. Examples include thickening, thinning, deformity, and separation from the nail bed.
Nails, Ingrown
Excessive lateral nail growth into the nail fold. Because the lateral margin of the nail acts as a foreign body, inflammation and granulation may result. It is caused by improperly fitting shoes and by improper trimming of the nail.
Onycholysis
Separation of nail plate from the underlying nail bed. It can be a sign of skin disease, infection (such as ONYCHOMYCOSIS) or tissue injury.
Yellow Nail Syndrome
A rare condition characterized by the presence of yellow nails, LYMPHEDEMA, and/or PLEURAL EFFUSION with respiratory tract involvement. Abnormal lymphatic network may play a role in its etiology. Occasionally inherited, yellow nail syndrome mostly is sporadic without apparent family history.
About the L60 Code Range
Changes to the nails fall within the skin appendage group.
The subdivisions distinguish named nail disorders, such as an L60.0 ingrowing nail and L60.5 yellow nail syndrome, from L60.8 other nail disorders and L60.9 unspecified nail disorders.
