About L12.3
L12.3 is the ICD-10-CM diagnosis code for acquired epidermolysis bullosa. It belongs to category L12 (pemphigoid), block L10-L14 (bullous disorders) and chapter 12 (diseases of the skin and subcutaneous tissue). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within L12 (pemphigoid), L12.3 is specifically for acquired epidermolysis bullosa. Related codes cover bullous pemphigoid (L12.0), cicatricial pemphigoid (L12.1), chronic bullous disease of childhood (L12.2), other pemphigoid (L12.8) and unspecified (L12.9).
To report this condition, pick the subcode that matches the documentation: L12.30 (unspecified), L12.31 (drug) and L12.35 (bullosa).
Don't report L12.3 together with the conditions in its Excludes1 note: epidermolysis bullosa (congenital) (Q81.-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
