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

This diagnosis code signifies a break in the pisiform bone, one of the small carpal bones in the wrist, where the bone fragments are no longer in their normal anatomical alignment. This specific code indicates that the affected wrist (left or right) was not documented, and it represents the initial treatment for a fracture that has not broken through the skin.

This code is appropriate for documenting the initial encounter for a patient presenting with a pisiform fracture that is displaced and the skin remains intact. It should be used when the medical record does not specify whether the injury occurred in the left or right wrist.

• Ensure documentation clearly states "displaced" and "closed fracture" for accurate code assignment.
• Only use this code for the initial phase of treatment; subsequent encounters will require different seventh characters.
• Avoid this code if the laterality (left or right wrist) is specified in the medical record; more specific codes exist.
