Displaced comminuted fx shaft of ulna, left arm, sequela

This code signifies a past injury to the left ulna, specifically a comminuted fracture of the shaft that was displaced. "Sequela" indicates that this code is used to report a condition or complication that is the residual effect of that previous fracture, rather than the acute injury itself.

This code is appropriate when a patient presents with a current problem or condition directly resulting from a previously healed (or healing) displaced comminuted fracture of the left ulnar shaft. Examples include chronic pain, nonunion, malunion, nerve damage, or restricted range of motion attributable to the old fracture. It should not be used for the initial treatment of the acute fracture.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, malunion).
• Ensure documentation clearly links the current condition to the previous left ulnar shaft fracture.
• Verify laterality (left arm) and fracture type (comminuted, displaced shaft) are accurately reflected.
