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 2027, 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.
Childhood Linear IgA Disease
A blistering disorder characterized by linear deposition of IgA at the dermoepidermal junction.
Epidermolysis Bullosa Acquisita
Form of epidermolysis bullosa characterized by trauma-induced, subepidermal blistering with no family history of the disease. Direct immunofluorescence shows IMMUNOGLOBULIN G deposited at the dermo-epidermal junction.
Pemphigoid, Benign Mucous Membrane
A chronic blistering disease with predilection for mucous membranes and less frequently the skin, and with a tendency to scarring. It is sometimes called ocular pemphigoid because of conjunctival mucous membrane involvement.
Pemphigoid, Bullous
A chronic and relatively benign subepidermal blistering disease usually of the elderly and without histopathologic acantholysis.
About the L12 Code Range
Pemphigoid belongs to a group of blistering skin disorders. Bullous pemphigoid is a chronic blistering disease beneath the outer skin layer, usually seen in older adults.
The subdivisions distinguish bullous pemphigoid (L12.0), cicatricial pemphigoid (L12.1), and chronic bullous disease of childhood (L12.2). Acquired epidermolysis bullosa (L12.3) separates unspecified, drug-related, and other forms. Other pemphigoid and unspecified pemphigoid have separate subdivisions.
