Nondisp fx of pisiform, unspecified wrist, sequela

This code signifies a healed or residual condition resulting from a prior fracture of the pisiform bone in an unspecified wrist. The original fracture was not displaced, meaning the bone fragments remained in their anatomical alignment. The "sequela" indicates that this code is used to report a current problem or condition that is a direct consequence of that old injury.

Apply this code when documenting a long-term complication or late effect directly attributable to a previously sustained, nondisplaced pisiform fracture of an unspecified wrist. Examples include chronic pain, stiffness, or functional limitations that persist after the initial healing period. This code is not for reporting the acute fracture itself.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, malunion).
• Ensure documentation clearly links the current condition to the old pisiform fracture and specifies the "unspecified wrist" if laterality is not documented.
• Do not use this code for initial or subsequent encounters for the active treatment of the acute fracture.
