Nondisp comminuted fx shaft of ulna, unsp arm, sequela

This code signifies a past injury involving a comminuted fracture of the shaft of the ulna that has since healed, but the patient is now experiencing a residual condition or complication directly related to that old fracture. The fracture itself was nondisplaced, meaning the bone fragments remained in their normal anatomical alignment. The specific arm affected is not documented.

Apply this code when a patient presents with a long-term consequence (e.g., chronic pain, limited range of motion, nonunion, malunion, nerve damage) stemming from a previously sustained, nondisplaced comminuted ulnar shaft fracture. This code is appropriate for follow-up encounters where the sequela, not the acute fracture, is the primary reason for the visit.

• Always sequence the code for the specific sequela (e.g., chronic pain, arthritis) first, followed by this sequela code.
• Ensure documentation clearly links the current condition to the old ulnar fracture.
• Do not use this code for the initial treatment of the acute fracture; it is exclusively for residual conditions.
