Frostbite with tissue necrosis of left finger(s), sequela

This code signifies a long-term complication or late effect of frostbite affecting one or more fingers on the left hand, where the tissue damage has progressed to necrosis (tissue death). It indicates that the initial frostbite injury occurred in the past, and the patient is now experiencing residual issues related to the dead tissue.

Apply this code when documenting follow-up care for a patient who previously sustained frostbite to the left fingers, and the current encounter addresses ongoing problems, such as chronic pain, infection, or functional impairment, directly resulting from tissue necrosis. This code is appropriate for situations where the acute frostbite injury has resolved, but its lasting effects are being managed.

• Always assign an additional code to specify the specific sequela being treated (e.g., pain, infection, gangrene).
• Ensure documentation clearly links the current condition to a past frostbite injury of the left fingers with necrosis.
• This "S" (sequela) encounter code is used for complications or conditions that arise as a direct result of a previous injury, after the acute phase has passed.
