Ingrowing nail

This code represents an onychocryptosis, a common nail disease where the nail plate, typically of the great toe, grows into the surrounding soft tissue. This penetration causes inflammation, pain, and can lead to infection if not properly managed. It is often a result of improper nail trimming, ill-fitting footwear, or trauma.

Use this code when documentation clearly indicates an ingrown nail, regardless of laterality or specific toe affected, and without mention of infection. This diagnosis is typically supported by physical exam findings noting erythema, edema, and tenderness at the nail fold where the nail plate is embedded.

• Do not use this code if there is an associated infection; instead, refer to codes in the L03.0 series for cellulitis or abscess.
• Laterality (left/right) is not specified for this code, so it applies to either foot or any toe.
• Ensure the documentation specifies "ingrown nail" or "onychocryptosis" to support this diagnosis.
