Other fracture of upper end of unspecified ulna, sequela

This code signifies a long-term complication or late effect stemming from a previously sustained fracture in the upper portion of the ulna, where the specific side (left or right) is not documented. These sequelae can include chronic pain, nonunion, malunion, or functional limitations that persist after the initial healing phase of the fracture.

Use this code when documenting a patient presenting with a current condition directly attributable to an old fracture of the proximal ulna, and the medical record does not specify which arm was affected. This is appropriate for follow-up encounters addressing residual problems from the original injury, rather than the acute fracture itself.

• Always assign an additional code to describe the specific nature of the sequela (e.g., M25.52- for chronic elbow pain).
• Ensure documentation clearly links the current condition to the old fracture.
• Avoid using this code for acute fractures; it is exclusively for late effects.
