About coding leprosy

The ICD-10-CM code for leprosy is A30 (Leprosy [Hansen's disease]). The official index lists 33 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on A30.

To report this condition, pick the subcode that matches the documentation: A30.0 (leprosy), A30.1 (leprosy), A30.2 (leprosy), A30.3 (leprosy), A30.4 (leprosy), A30.5 (leprosy), A30.8 (leprosy) and A30.9 (unspecified).

Don't report A30 together with the conditions in its Excludes1 note: sequelae of leprosy (B92).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
