Blister (nonthermal), left lesser toe(s), subs encntr

This code signifies a non-heat-related fluid-filled lesion on one or more of the smaller toes of the left foot. This blister is being addressed during a follow-up visit after the initial treatment or assessment.

Apply this code when a patient presents for ongoing care of a blister on their left lesser toe(s) that was not caused by a burn or frostbite. This includes situations like wound checks, dressing changes, or further evaluation of a previously diagnosed non-thermal blister.

• Ensure documentation specifies "left" and "lesser toe(s)" to support this code.
• Confirm the encounter is subsequent, indicating ongoing care rather than the initial presentation.
• Verify the blister etiology is non-thermal; if thermal, a different code series would apply.
