Disp fx of pisiform, right wrist, init for clos fx

This code signifies a break in the pisiform bone, a small carpal bone located on the ulnar side of the wrist, where the bone fragments are no longer in their normal anatomical alignment. The fracture is closed, meaning the skin remains intact over the injury site. This specific code is for the initial treatment of such an injury in the right wrist.

Apply this code when documenting the first encounter for a patient presenting with a displaced fracture of the pisiform bone in their right wrist, confirmed by imaging. This typically occurs following direct trauma to the hypothenar eminence or a fall onto an outstretched hand. It is used for the initial assessment, diagnosis, and treatment planning of the acute injury.

• Ensure documentation clearly specifies "displaced" and "closed" for the pisiform fracture.
• Verify the laterality is correctly identified as the "right wrist."
• This "A" initial encounter suffix is only used for the active treatment phase of the fracture.
