2027 ICD-10-CM Diagnosis Code A30.2Borderline tuberculoid leprosy
ICD-10-CM Codes›A00–B99›A30-A49›A30
- Billable — Valid for Submission
- CC — Complication or Comorbidity
- Not Chronic
A30.2 is a billable ICD-10-CM diagnosis code for borderline tuberculoid leprosy. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 867 through 869. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 3 closely related codes. Coders also document this condition as borderline leprosy. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Bacterial infections.

a chronic granulomatous infection caused by mycobacterium leprae. the granulomatous lesions are manifested in the skin, the mucous membranes, and the peripheral nerves. two polar or principal types are lepromatous and tuberculoid.
Patient EducationClinical
Mycobacterial Infections
Mycobacteria are a type of germ. There are many different kinds. The most common one causes tuberculosis. Another one causes leprosy. Still others cause infections that are called atypical mycobacterial infections. They aren't "typical" because they don't cause tuberculosis.

Questions About A30.2Overview
What is the ICD-10 code for borderline tuberculoid leprosy?
The ICD-10-CM code for borderline tuberculoid leprosy is A30.2 (sometimes written as A302). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is A30.2 (Leprosy [Hansen's disease]) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report borderline tuberculoid leprosy on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does A30.2 group to?
When borderline tuberculoid leprosy is the principal diagnosis on an inpatient stay, it groups to MS-DRG 867, 869, 868, with relative weights from 0.6784 to 2.1855 depending on complications. Higher weights mean higher Medicare reimbursement.
Is A30.2 a CC or MCC?
CMS lists A30.2 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 3 closely related codes in its exclusion list.
Can A30.2 be reported with B92?
Not as a rule. The Excludes1 note at A30, which applies to A30.2, lists "sequelae of leprosy (B92)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
