Other disorders of diminished melanin formation

This code represents a range of conditions characterized by a reduction in melanin production, leading to areas of hypopigmentation or depigmentation of the skin, hair, or eyes, that are not classified elsewhere. These disorders are distinct from albinism and vitiligo, which have their own specific codes. The diminished melanin formation can be localized or generalized.

Use this code for documented cases of hypopigmentation or depigmentation that do not fit the criteria for albinism (E70.3) or vitiligo (L80). This includes conditions like post-inflammatory hypopigmentation, chemical leukoderma, or other unspecified forms of melanin deficiency. Documentation should clearly state the presence of diminished melanin formation and rule out more specific diagnoses.

• Do not use this code for albinism (E70.3) or vitiligo (L80); these have dedicated codes.
• Ensure documentation specifies the cause of the diminished melanin formation if known, as more specific codes may exist for certain etiologies (e.g., drug-induced).
• Consider an additional code to identify any underlying systemic condition if applicable and documented.
