About A30
A30 is the ICD-10-CM diagnosis code for leprosy [Hansen's disease]. It belongs to block A30-A49 (other bacterial diseases) and chapter 1 (certain infectious and parasitic diseases). It is a header code, so it can't be reported by itself; one of its 8 subcodes must be used instead.
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.
