Blister (nonthermal), right lower leg, subsequent encounter

This code indicates a non-heat-related fluid-filled lesion on the right lower leg, specifically when the patient is receiving follow-up care for the condition. It signifies that the initial treatment has already occurred, and the current encounter is for continued management, healing, or addressing complications.

Use this code for patients presenting for a follow-up visit concerning a blister on their right lower leg that was not caused by a burn or frostbite. This includes scenarios where the blister is being re-evaluated, dressed, or monitored for healing after initial presentation and treatment.

• Ensure the blister is specifically located on the right lower leg and is not due to thermal injury.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine follow-up care for a condition already treated.
• Do not use for the initial presentation of the blister; a different seventh character would be appropriate for the initial encounter.
