Indeterminate leprosy [group I]

This code represents a diagnosis of indeterminate leprosy, also known as group I leprosy. This is the earliest and mildest form of leprosy, characterized by a single skin lesion with sensory loss, but without definitive nerve involvement or bacterial confirmation, making the specific type of leprosy difficult to classify at presentation.

Use this code when a patient presents with initial signs and symptoms suggestive of leprosy, but definitive classification into paucibacillary or multibacillary types is not yet possible. Documentation should clearly indicate "indeterminate leprosy" or "group I leprosy" based on clinical findings and initial diagnostic workup, prior to further differentiation.

• Do not use this code once the type of leprosy (e.g., tuberculoid, lepromatous) has been definitively diagnosed.
• Ensure documentation specifies "indeterminate" or "group I" to support this code, rather than just "suspected leprosy."
• Consider sequencing with codes for any associated symptoms or complications if applicable, though indeterminate leprosy often presents with minimal other findings.
