Other acquired epidermolysis bullosa

This code signifies an acquired blistering skin disorder characterized by fragile skin that easily forms blisters and erosions with minor trauma, but which does not fit the criteria for other specified acquired epidermolysis bullosa types. It represents a non-hereditary form where the blistering is due to an autoimmune process or other external factors.

Assign this code when documentation indicates a diagnosis of acquired epidermolysis bullosa that is not specifically classified elsewhere (e.g., bullous pemphigoid, epidermolysis bullosa acquisita). This typically applies when the specific subtype of acquired epidermolysis bullosa is not fully identified or falls into an "other specified" category. Supporting documentation should clearly state "other acquired epidermolysis bullosa" or describe an acquired blistering disorder consistent with this classification.

• Ensure the documentation explicitly states "acquired" to differentiate from hereditary forms.
• Avoid using this code if a more specific acquired epidermolysis bullosa subtype (e.g., epidermolysis bullosa acquisita) is documented; use the specific code instead.
• Always review the medical record for any underlying systemic conditions or autoimmune disorders that may be associated and require additional coding.
