Disp fx of trapezium, unsp wrist, subs for fx w routn heal

This code describes a displaced fracture of the trapezium bone in an unspecified wrist, indicating that the bone fragments are not in their normal alignment. The "subsequent encounter" aspect signifies that the patient is receiving follow-up care for this fracture, which is currently healing routinely without complications.

Use this code for a patient presenting for a follow-up visit after an initial diagnosis of a displaced trapezium fracture, where the specific wrist (left or right) was not documented. This applies when the fracture is progressing through an expected healing process, such as during cast changes, physical therapy, or routine clinical assessments of healing.

• Ensure documentation clearly states "displaced" and that the encounter is for "subsequent" care with "routine healing."
• Verify that the specific wrist (left or right) is not documented; otherwise, a more specific code should be used.
• Do not use for initial encounters, nonunion, malunion, or delayed healing; separate codes exist for those scenarios.
