ICD-10 Code A30.2 – Borderline tuberculoid leprosy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A30.2 – Borderline tuberculoid leprosy
What it is
A30.2 identifies borderline tuberculoid leprosy, a form of Hansen disease with features between tuberculoid and lepromatous disease. Use it when documentation specifically names this borderline subtype.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include skin lesions with reduced sensation and involvement of peripheral nerves, but the exact pattern should be confirmed in the record.
When to use this code
Use A30.2 when the clinician documents borderline tuberculoid leprosy, borderline tuberculoid Hansen disease, or an equivalent diagnosis. It is appropriate when the subtype is clearly stated in the assessment, problem list, or discharge summary.
If the record only says leprosy, Hansen disease, or another subtype, check documentation before assigning this code. You should code the documented form precisely rather than assuming the borderline tuberculoid classification.
Do not use for
Do not use A30.2 for unspecified leprosy or for other leprosy subtypes such as tuberculoid, lepromatous, or indeterminate disease. Check documentation if the subtype is unclear.
Coding tip
Code the exact documented leprosy subtype; if borderline tuberculoid is not explicitly stated, query or review the chart before assigning A30.2.
