ICD-10 Code A30.9 – Leprosy, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A30.9 – Leprosy, unspecified
What it is
A30.9 identifies leprosy when the type is not further specified. Use it for documented Hansen disease without details that support a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include skin lesions, reduced sensation, and peripheral nerve involvement, but the record must support leprosy rather than another cause.
When to use this code
Use this code when the provider diagnoses leprosy but does not document a specific form or subtype. It also fits when the note confirms Hansen disease and no further classification is available. If the record names a specific type, code that instead.
Do not use for
Do not use A30.9 when the documentation clearly identifies a different leprosy subtype. Also avoid it if leprosy is only suspected, ruled out, or replaced by another diagnosis. Check documentation.
Coding tip
Query for specificity when the chart says “leprosy” but does not state the type.
