Question: What’s the best ICD-10-CM code to describe a resident who’s admitted after having a limb amputated? Answer: Use Z47.81 (Encounter for orthopedic aftercare following surgical amputation) for this situation, but make sure you know the entirety of the ICD-10-CM instructions for this code. The ICD-10 code instructions say to use an additional code to identify the limb amputated (Z89.-) and to not use this code for situations involving healing fracture-code to fracture with 7th character.
