Acquired absence of unspecified finger(s)

This code indicates the complete absence of one or more fingers due to an acquired cause, such as trauma or surgical amputation, where the specific finger(s) involved are not documented. It signifies a permanent loss of digital structures on the hand.

Apply this code when documentation confirms an acquired amputation of a finger or fingers, but the medical record does not specify which particular finger(s) (e.g., thumb, index, middle, ring, little) were lost. This is appropriate for follow-up care, prosthetic fitting, or disability evaluations when the precise digit is unknown.

• Only use this code when the specific finger(s) are truly unspecified in the medical record.
• If the laterality (left or right hand) is known, use a more specific code from the Z89.02- subcategory.
• Avoid using this code if documentation allows for a more precise code identifying the specific finger(s) or laterality.
