Frostbite w tissue necrosis of unsp hip and thigh, sequela

This code signifies a long-term complication or residual effect stemming from frostbite that caused tissue death (necrosis) in an unspecified area of the hip or thigh. The original frostbite injury is no longer acute, and the current encounter addresses the lasting consequences of that damage.

Apply this code when a patient presents for treatment of a chronic condition directly resulting from a past frostbite injury to the hip or thigh, where the frostbite led to tissue necrosis. Examples include managing chronic pain, non-healing ulcers, or functional limitations directly attributable to the necrotic damage from the original frostbite.

• This "S" encounter code indicates a sequela, meaning it's used for complications or conditions arising from the initial injury, not the acute injury itself.
• Ensure documentation clearly links the current condition to a previous frostbite event with tissue necrosis of the hip/thigh.
• If the specific hip or thigh (left or right) is known, a more specific code within the T34.6x category should be used.
