L81.9
ICD-10-CMThis code signifies a general, unspecified abnormality in the color of the skin, hair, or nails. It indicates that the normal production or distribution of melanin is disrupted, leading to areas that are either hyperpigmented (darker) or hypopigmented (lighter) than the surrounding tissue. The specific type or cause of the pigmentation disorder is not documented or known.
Use this code when the medical record clearly indicates a disorder of pigmentation, but the provider has not specified the exact nature, type, or etiology of the condition. This is appropriate for initial encounters where further diagnostic workup is pending, or when the specific diagnosis remains undetermined after investigation. Documentation should mention "pigmentation disorder," "skin discoloration," or similar terms without further detail.
