Pemphigoid, unspecified

This code represents pemphigoid, a group of autoimmune blistering skin diseases, when the specific type of pemphigoid has not been identified or documented. These conditions are characterized by the formation of blisters on the skin and/or mucous membranes due to an autoimmune attack on components of the basement membrane zone.

Use this code when the provider's documentation clearly states "pemphigoid, unspecified" or "pemphigoid NOS." This is appropriate when a definitive diagnosis of a specific pemphigoid subtype (e.g., bullous pemphigoid, cicatricial pemphigoid) has not yet been established or documented in the medical record.

• Avoid using this code if a more specific type of pemphigoid is documented; always code to the highest level of specificity.
• Query the provider if the documentation indicates "pemphigoid" but lacks further detail, to determine if a more specific diagnosis can be obtained.
• Consider co-reporting codes for associated symptoms or complications, such as pruritus (L29.x) or secondary infection (e.g., L03.x), if documented.
