Pemphigoid (L12) ICD-10-CM
The L12 code range covers pemphigoid with 10 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the L12 range.
Dermatitis Herpetiformis
Rare, chronic, papulo-vesicular disease characterized by an intensely pruritic eruption consisting of various combinations of symmetrical, erythematous, papular, vesicular, or bullous lesions. The disease is strongly associated with the presence of HLA-B8 and HLA-DR3 antigens. A variety of different autoantibodies has been detected in small numbers in patients with dermatitis herpetiformis.
About the L12 Code Range
ICD-10 code section L12 covers pemphigoid, a group of rare autoimmune skin disorders characterized by blistering. These codes are used to classify and report various types of pemphigoid, including bullous, cicatricial, and acquired epidermolysis bullosa forms.
This set includes specific codes such as L12.0 for bullous pemphigoid, often known by synonyms like dermatis herpetiformis, drug-induced bullous pemphigoid, or pemphigoid vegetans. L12.1 designates cicatricial pemphigoid, also called benign mucous membrane pemphigoid or ocular cicatricial pemphigoid, reflecting its mucosal involvement and scarring features. For pediatric cases, L12.2 identifies chronic bullous disease of childhood, which includes synonyms such as dermatitis herpetiformis and linear IgA dermatosis. Additionally, acquired epidermolysis bullosa and its drug-induced variants fall under L12.3 with subcodes like L12.30 and L12.31. General or unspecified pemphigoid types are grouped under L12.8 and L12.9. Using these ICD-10 codes ensures precise classification and appropriate documentation of these inflammatory skin conditions.
