Acquired absence of left thumb

This code signifies the permanent loss of the left thumb due to an event after birth, such as trauma, surgery, or disease. It indicates that the thumb was once present but is now missing. This is distinct from a congenital absence.

Apply this code for patients presenting with documentation of a surgically amputated left thumb, or a left thumb lost due to an accident or severe infection. It is used to report the sequela of such an event, not the acute injury itself.

• Ensure documentation specifies "acquired" and not "congenital" absence.
• Verify laterality (left) and digit (thumb) are clearly stated in the medical record.
• Do not use this code for partial absence; a different code would be appropriate for a stump or partial amputation.
