Nondisp fx of triquetrum bone, l wrs, subs for fx w malunion

This code describes a left wrist triquetrum bone fracture that was initially nondisplaced but has since healed improperly, resulting in malunion. The patient is presenting for follow-up care related to this previously treated fracture and its current complication.

This code is appropriate for documenting a patient encounter where the primary focus is the management of a malunited, previously nondisplaced triquetrum fracture of the left wrist. This includes scenarios such as evaluating pain, reduced range of motion, or other functional impairments stemming from the malunion, or planning for corrective procedures.

• Ensure documentation clearly specifies "left wrist" and "triquetrum" to support laterality and bone specificity.
• Confirm that the encounter is for a subsequent visit related to the fracture and that malunion is explicitly documented.
• Do not use this code for initial fracture treatment or for nonunion, which has a separate code.
