Disp fx of triquetrum bone, unspecified wrist, sequela

This code signifies a past fracture of the triquetrum bone in an unspecific wrist, where the bone fragments were not in their normal anatomical alignment at the time of the initial injury. The "sequela" designation indicates that this code is used to report conditions or complications that are the late effects of the original fracture, even if the acute phase of the injury has resolved.

Apply this code when documenting a patient presenting with a long-term complication or residual effect directly related to a previously displaced triquetral fracture of an unspecified wrist. This could include chronic pain, limited range of motion, nonunion, malunion, or post-traumatic arthritis stemming from the original injury.

• Always assign a sequela code as a secondary diagnosis, following the code for the specific late effect being treated.
• Ensure documentation clearly links the current condition to the previous displaced triquetral fracture.
• Do not use this code for acute or active displaced triquetral fractures; specific acute fracture codes should be used for those encounters.
