Disp fx of hook process of hamate bone, right wrist, sequela

This code signifies a past injury involving a fracture of the hook-shaped projection of the hamate bone in the right wrist, where the bone fragments are no longer in their normal anatomical alignment. The "sequela" designation indicates that this code is used to report a condition or complication that is a residual effect of the original fracture, rather than the acute injury itself.

This code is appropriate when a patient presents with ongoing symptoms or complications directly attributable to a previously sustained and healed, or partially healed, displaced fracture of the right hamate hook. Examples include chronic pain, nonunion, malunion, or nerve impingement resulting from the old fracture. It should not be used for the initial acute injury.

• Always ensure documentation clearly specifies "sequela" or a residual condition stemming from the old fracture.
• Verify laterality (right wrist) and the specific bone (hamate hook) are explicitly stated in the medical record.
• Do not use this code for acute fractures; instead, select an appropriate acute fracture code.
