Disp fx of pisiform, left wrist, init for opn fx

This code signifies a break in the pisiform bone, a small carpal bone on the ulnar side of the wrist, where the bone fragments are no longer in their normal anatomical alignment. The fracture is open, meaning there is a break in the skin communicating with the fracture site, and this is the first time the patient is receiving treatment for this specific injury.

This code is appropriate for documenting the initial treatment of a patient presenting with a visibly displaced pisiform fracture of the left wrist, where the injury has also caused a wound exposing the bone. This would include scenarios such as a fall onto an outstretched hand resulting in a compound fracture of the pisiform.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the pisiform.
• Verify the laterality is "left wrist" to match the code.
• Confirm this is the initial encounter for treatment of this specific fracture, not a subsequent visit.
