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

This code signifies a break in the pisiform bone, a small carpal bone located in the wrist, that has not shifted from its normal anatomical position. The fracture is in an unspecified wrist and is being treated for the first time, with the skin over the fracture remaining intact.

Apply this code when documentation confirms a non-displaced pisiform fracture resulting from a fall or direct trauma to the wrist, and the patient is presenting for initial treatment of this closed injury. This is appropriate for cases where the specific wrist (left or right) is not documented.

• Ensure documentation explicitly states "nondisplaced" and "closed fracture" for accurate code assignment.
• Verify that this is the patient's initial encounter for treatment of this specific fracture.
• If the specific wrist (left or right) is known, a more specific code should be used.
