Displaced fracture of neck of unspecified radius, sequela

This code indicates a long-term complication or late effect stemming from a previously sustained displaced fracture of the neck of the radius, where the specific side (left or right) is not documented. It signifies that the initial injury has healed, but residual issues related to the fracture persist.

Apply this code when documenting conditions such as malunion, nonunion, chronic pain, limited range of motion, or deformity that are directly attributable to a past displaced radial neck fracture. This is used after the acute phase of the fracture has passed and the patient is presenting for follow-up or treatment of these lasting effects.

• Always sequence this "sequela" code after the primary diagnosis describing the specific late effect (e.g., M84.8x for malunion).
• Ensure documentation clearly links the current condition to a prior displaced radial neck fracture.
• Avoid using this code for acute or active fractures; those require codes from the initial encounter or subsequent encounter categories.
