Displaced fracture of pisiform, left wrist, sequela

This code indicates a past injury to the pisiform bone in the left wrist that resulted in a displaced fracture, and the patient is now experiencing a long-term complication or residual effect from that fracture. The pisiform is a small, pea-shaped bone located within the flexor carpi ulnaris tendon on the ulnar side of the wrist.

Use this code when documenting a patient presenting with ongoing issues, such as pain, limited range of motion, or nerve impingement, directly attributable to a previously sustained and healed, but displaced, fracture of the left pisiform. This code is appropriate for follow-up encounters addressing the chronic sequelae, not the initial acute injury.

• Requires a seventh character "S" for sequela, indicating a complication or residual effect of a past injury.
• Do not use for the initial treatment of an acute fracture; instead, use an acute fracture code.
• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic pain, nonunion, malunion).
