Displaced segmental fx shaft of humerus, left arm, sequela

This code describes a past injury to the left humerus, specifically a segmental fracture of the shaft that was displaced. The "sequela" designation indicates that this code is used to report a condition or complication that is a direct result of the original fracture, even if the fracture itself has healed.

This code is used when a patient presents with a current problem or condition that is a long-term consequence of a previously sustained, displaced segmental fracture of the left humeral shaft. Examples include chronic pain, nonunion, malunion, nerve damage, or limited range of motion directly 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 current condition being treated.
• Ensure documentation clearly links the current sequela to the historical displaced segmental fracture of the left humeral shaft.
• Do not use this code for acute or active fractures; refer to the appropriate acute fracture codes in the S42.3- series.
