Frostbite w tissue necrosis of unsp hip and thigh, init

This code signifies frostbite affecting the hip and/or thigh region, where the tissue has died (necrosis) as a direct result of the cold injury. It indicates the initial presentation or treatment for this specific condition, implying the patient has not received prior care for this episode of frostbite.

Apply this code when documentation clearly states frostbite of the hip and/or thigh with confirmed tissue necrosis, and the patient is receiving their first treatment for this injury. This would include situations like emergency department visits or initial hospital admissions for such a condition.

• Ensure documentation specifies "necrosis" or "tissue death" due to frostbite; otherwise, a different frostbite code may be more appropriate.
• Confirm the affected body part is the hip and/or thigh; avoid using for other lower extremity sites.
• Verify this is the "initial encounter" for the frostbite episode. Subsequent encounters would require a different seventh character.
