Acquired absence of right ankle

This code indicates the complete absence of the right ankle joint and/or foot, which was not present at birth but resulted from an amputation or other acquired cause. It signifies a missing right lower extremity at or above the ankle level due to a surgical removal or traumatic event.

Use this code for patients who have undergone a right ankle disarticulation or a transtibial (below-knee) amputation affecting the right side. It is appropriate for documenting the long-term sequela of such a procedure, regardless of the original reason for the amputation.

• Always specify laterality (right, left, or bilateral) when documenting limb absence.
• Do not use this code for congenital absence; a different code series applies for birth defects.
• Code any associated complications of the amputation (e.g., phantom limb pain, stump infection) separately.
