Displaced segmental fx shaft of humerus, right arm, sequela

This code signifies a past injury involving a fracture in the middle section (shaft) of the right humerus that broke into at least three pieces (segmental) and where the bone fragments were not properly aligned (displaced). The "sequela" designation indicates that this code is used to report a condition or complication that is a direct result of this old fracture, rather than the initial acute injury itself.

This code is appropriate when a patient presents with a long-term complication or residual effect stemming from a previously sustained, displaced segmental fracture of the right 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 ensure documentation clearly links the current condition to the old fracture.
• Do not use this code for the initial encounter of the fracture; instead, use the acute fracture codes.
• Consider additional codes for specific sequelae (e.g., M25.511 for chronic right shoulder pain, G54.0 for brachial plexus disorders).
