Disp fx of unspecified radial styloid process, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained fracture of the radial styloid process, where the bone fragments were not in their anatomical position. The specific side (left or right) of the wrist is not documented or is unknown. These sequelae can include chronic pain, limited range of motion, nonunion, malunion, or post-traumatic arthritis.

Utilize this code when a patient presents with ongoing issues directly attributable to a past displaced fracture of the radial styloid, and the documentation does not specify the affected side. This is appropriate for follow-up visits addressing the chronic consequences of the injury, rather than the initial acute treatment.

• Always sequence this code after the primary diagnosis describing the specific sequela (e.g., M19.031 for primary osteoarthritis of the wrist).
• Ensure documentation clearly links the current condition to the prior displaced radial styloid fracture.
• Avoid using this code for acute or subacute fractures; it is exclusively for late effects.
