Cicatricial pemphigoid

This code represents a chronic, autoimmune subepidermal blistering disease primarily affecting mucous membranes, such as the conjunctiva, oral cavity, and genitourinary tract, but can also involve the skin. It is characterized by the formation of bullae that heal with scarring, potentially leading to significant functional impairment, especially in the eyes.

Assign this code for patients diagnosed with cicatricial pemphigoid, also known as benign mucous membrane pemphigoid. Documentation should clearly indicate the presence of this specific autoimmune blistering disorder, often confirmed by biopsy and immunofluorescence studies.

• Differentiate from other bullous diseases like bullous pemphigoid (L12.0) or pemphigus (L10.-) which have distinct clinical and pathological features.
• Code any associated complications, such as blindness (H54.-) or esophageal strictures (K22.2), in addition to this primary diagnosis.
• Ensure the medical record specifies "cicatricial" to support the use of this more specific code over a general pemphigoid diagnosis.
