Blister (nonthermal), unspecified lower leg, subs encntr

This code signifies a non-thermal blister located on an unspecified part of the lower leg, indicating that the patient is receiving follow-up care for this condition. It differentiates from blisters caused by burns or frostbite.

Apply this code when documenting subsequent encounters for a blister on the lower leg where the specific anatomical site (e.g., ankle, calf) is not specified in the medical record. This is appropriate for ongoing treatment, monitoring, or healing of such a blister.

• Ensure the documentation clearly states the blister is non-thermal.
• Only use this code when the specific lower leg location is not documented; otherwise, a more specific code should be chosen.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
