Leukoderma, not elsewhere classified

This code signifies a condition characterized by localized or widespread areas of depigmentation of the skin, resulting in lighter patches. It represents a loss of melanin, the pigment responsible for skin color, that is not attributable to other specific, classified causes.

Apply this code when documentation indicates leukoderma without a more specific underlying cause identified, such as vitiligo, chemical-induced leukoderma, or post-inflammatory hypopigmentation. It is appropriate for idiopathic cases or when the etiology is unknown and not further specified.

• Ensure documentation explicitly states "leukoderma, not elsewhere classified" or similar phrasing indicating an unspecified etiology.
• Do not use this code if a more specific diagnosis, such as vitiligo (L80), is documented.
• Consider sequencing this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-existing condition.
