Displaced fracture of pisiform, unspecified wrist, sequela

This code indicates a past fracture of the pisiform bone in the wrist that was displaced at the time of injury, with the specific wrist (left or right) not documented. It signifies a long-term complication or residual effect stemming from the original injury, rather than the acute fracture itself.

Apply this code when a patient presents for treatment of a condition that is a direct consequence of a previously sustained, displaced pisiform fracture, and the affected wrist is not specified in the medical record. This is used for follow-up care or management of chronic issues related to the old injury.

• Always sequence this code after the code for the primary condition being treated, if applicable.
• Ensure documentation clearly states the condition is a sequela of a displaced pisiform fracture.
• Avoid using this code for acute or initial treatment of a pisiform fracture; use the appropriate acute fracture code instead.
