Indeterminate leprosy

This code represents the earliest and mildest form of leprosy, characterized by a single or a few ill-defined skin lesions with sensory loss, but without clear neurological involvement or acid-fast bacilli on smear. It is a provisional diagnosis made when the clinical picture is suggestive of leprosy but not yet definitive for a specific type.

Use this code for patients presenting with initial, non-specific signs of leprosy where a definitive classification (e.g., tuberculoid, lepromatous) cannot yet be established. Documentation should clearly indicate "indeterminate leprosy" or a similar provisional diagnosis based on clinical findings and before histopathological or bacteriological confirmation of a specific type.

• Do not use this code once a definitive type of leprosy has been diagnosed; instead, code to the specific type.
• Ensure documentation supports the "indeterminate" nature, often implying further diagnostic workup is pending.
• This code is typically used for initial presentations and may be followed by a more specific leprosy code upon definitive diagnosis.
