Superficial frostbite of unspecified hip and thigh, sequela

This code signifies a past episode of superficial frostbite affecting an unspecified area of the hip and/or thigh, where the residual effects or complications of that frostbite are now being treated. Superficial frostbite involves freezing of the skin and subcutaneous tissue, but not deeper structures. The "sequela" indicates that the current encounter is for a condition resulting from the original frostbite injury.

Use this code when documenting and billing for the long-term effects or complications of a superficial frostbite injury to the hip or thigh, such as chronic pain, numbness, skin discoloration, or sensitivity to cold, after the initial frostbite injury has healed. This code is appropriate when the patient is presenting for treatment of these persistent issues, not for the acute frostbite itself.

• Ensure documentation clearly links the current condition to a previous superficial frostbite of the hip/thigh.
• Do not use this code for acute frostbite; use the appropriate acute frostbite code from the T33-T34 range.
• Always look for more specific laterality (left/right) if documented, as "unspecified" should be a last resort.
