Blister (nonthermal) of abdominal wall, initial encounter

This code signifies a non-burn related blister located on the abdominal wall. These lesions are typically fluid-filled sacs that form on the skin due to friction, pressure, or other irritants, but not from heat exposure.

Use this code for the initial encounter when a patient presents with a blister on their abdomen that is clearly not caused by a thermal injury. This includes blisters resulting from tight clothing, prolonged pressure, or chemical irritants.

• Ensure the documentation explicitly states the blister is on the abdominal wall and is nonthermal.
• Verify this is the patient's first presentation or initial treatment for this specific blister.
• Look for additional codes to describe the underlying cause of the nonthermal blister if known and documented.
