What ICD codes are used for BKA?
While there are no codes with below-knee amputation (BKA) in their names, you can use specific BKA ICD-10 codes for BKA-related cases. Below are the relevant codes:
- Z89.511 – Acquired absence of right leg below knee: This code is used for patients who have undergone an amputation of the right leg below the knee.
- Z89.512 – Acquired absence of left leg below knee: Applicable for patients with an amputation of the left leg below the knee.
- Z89.519 – Acquired absence of unspecified leg below knee: This code is used when the specific leg (right or left) is not documented. While using specific codes (Z89.511 or Z89.512) is preferable, Z89.519 serves as an alternative when laterality is unknown.
