Acquired absence of right leg below knee

This code indicates the permanent absence of the right lower limb, specifically below the knee joint, due to a cause other than a congenital anomaly. This condition typically results from surgical amputation or traumatic injury.

Apply this code for patients who have undergone a right transtibial amputation (below the knee amputation) or experienced a traumatic loss of the right lower leg. It is used to document the current status of an acquired limb deficiency.

• Ensure documentation specifies "right" leg and "below knee" to differentiate from other amputation sites.
• This code is for acquired absence; do not use for congenital limb deficiencies.
• Always code the underlying reason for the amputation (e.g., diabetes, trauma, peripheral artery disease) as a primary or secondary diagnosis.
