Frostbite w tissue necrosis of right hip and thigh, sequela

This code signifies a past episode of frostbite affecting the right hip and thigh, which resulted in permanent tissue damage or death (necrosis). The "sequela" designation indicates that the patient is now presenting with a long-term complication or residual effect of that prior frostbite injury.

Apply this code when documenting a patient's current condition that is a direct, lasting consequence of frostbite to the right hip and thigh, specifically involving tissue necrosis. This would be used for follow-up care, management of chronic wounds, or addressing functional limitations stemming from the necrotic damage.

• Ensure documentation clearly links the current presentation to a previous frostbite injury of the right hip and thigh with tissue necrosis.
• The "S" at the end indicates sequela; do not use this code for acute frostbite.
• Code any current manifestations or complications of the necrosis (e.g., chronic ulcer, contracture) in addition to this sequela code.
