Acquired absence of unspecified shoulder

This code indicates the complete absence of a shoulder, which was not present at birth but resulted from an external cause such as trauma or surgical amputation. It signifies a missing shoulder joint and associated structures, without specifying which side (left or right) is affected.

This code is appropriate for documenting the sequelae of an amputation or other acquired condition leading to the loss of a shoulder. It should be used when the medical record clearly states the absence is acquired, but the laterality (left or right) is not specified.

• Always strive for laterality specificity (e.g., Z89.231 for right, Z89.232 for left) if documented.
• This code is for the absence of the shoulder, not for conditions affecting an existing shoulder.
• Do not use this code for congenital absence; refer to Q codes for congenital malformations.
