Superficial frostbite of left ear, subsequent encounter

This code signifies a superficial cold injury to the left ear, specifically frostbite, that is being treated during a follow-up visit. Superficial frostbite involves the skin and subcutaneous tissue, typically presenting with numbness, tingling, and a waxy appearance. The "subsequent encounter" indicates that the patient is receiving ongoing care for this previously diagnosed condition.

Apply this code when a patient presents for a follow-up appointment related to superficial frostbite of their left ear. This includes visits for wound care, monitoring for complications, or assessing healing progress after the initial treatment. It should be used after the initial encounter for the frostbite has been coded.

• Ensure documentation clearly specifies "left ear" and "superficial" frostbite.
• Confirm the encounter is for follow-up care, not the initial diagnosis or treatment.
• Verify the frostbite is not described as deep tissue involvement, which would require a different code.
