Pemphigoid
Chapter 12:Diseases of the skin and subcutaneous tissue
ICD-10 L12 is a used to indicate a diagnosis of pemphigoid.
Pemphigoid is a group of autoimmune blistering disorders characterized by the formation of subepithelial blisters. The most common form, bullous pemphigoid, typically presents with tense blisters on the skin, often in areas such as the abdomen, groin, and extremities. The condition primarily affects older adults, with a peak incidence in those over 60 years of age. The pathophysiology involves the immune system producing antibodies against components of the basement membrane, leading to the separation of the epidermis from the dermis. Disease progression can vary, with some patients experiencing spontaneous remissions while others may have persistent or recurrent lesions. Diagnosis is often confirmed through skin biopsy, which reveals the presence of subepithelial blisters and can be supplemented by direct immunofluorescence studies to detect autoantibodies. Clinicians must consider differential diagnoses, including other blistering disorders such as pemphigus vulgaris and dermatitis herpetiformis, to ensure accurate diagnosis and treatment.

L12 covers various forms of pemphigoid, primarily bullous pemphigoid, as well as other related autoimmune blistering conditions. Diagnostic criteria include the presence of subepithelial blisters and positive immunofluorescence findings.
L12 should be used when the diagnosis specifically indicates pemphigoid conditions, particularly when subepithelial blisters are confirmed. It is important to differentiate from pemphigus (L10) and other blistering disorders based on clinical presentation and biopsy results.
Documentation should include clinical findings such as blister characteristics, biopsy results, and immunofluorescence studies. Detailed patient history and treatment response are also essential for supporting the diagnosis.
