Disp fx of pisiform, unsp wrist, subs for fx w delay heal

This code describes a fracture of the pisiform bone in the wrist that is no longer in its anatomical position (displaced). The "G" seventh character indicates that the patient is in a subsequent encounter for the fracture, and the healing process is delayed.

Use this code for patients presenting for follow-up care of a pisiform fracture where imaging or clinical assessment confirms displacement and the fracture is not healing as expected. This would apply after initial treatment and during ongoing management of the delayed union.

• Ensure documentation specifies "displaced" and "delayed healing" for accurate seventh character assignment.
• Verify the encounter is for follow-up care, not initial treatment or a sequela.
• Confirm the specific bone involved is the pisiform.
