Blister (nonthermal) of right little finger, init encntr

This code signifies a non-burn related blister located on the right little finger. This injury involves the superficial separation of the skin layers, resulting in a fluid-filled lesion, and is being addressed for the first time.

Apply this code when documenting a patient's initial presentation for a blister on their right little finger that is not caused by heat, cold, or chemical exposure. This includes blisters resulting from friction, pressure, or contact with irritants.

• Ensure the documentation specifies the right little finger and confirms the blister is nonthermal.
• Verify this is the initial encounter for this specific injury; subsequent care would use a different seventh character.
• Look for details in the medical record regarding the cause of the blister to rule out thermal or chemical origins.
