Disp fx of shaft of first MC bone, left hand, sequela

This code signifies a past injury involving a fracture of the shaft of the first metacarpal bone (thumb) in the left hand, which was displaced at the time of the initial injury. The "sequela" designation indicates that this code is used to report a condition or complication that is a residual effect of that original fracture, even if the fracture itself has healed.

Use this code when documenting a current condition, symptom, or complication directly resulting from a previously displaced fracture of the left first metacarpal shaft. This includes chronic pain, malunion, nonunion, limited range of motion, or nerve damage that is a direct consequence of the old fracture. It should be used when the patient is presenting for treatment of these long-term effects, not for the initial acute fracture.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., M25.542 for chronic pain in left hand).
• Ensure documentation clearly links the current condition to the previous displaced fracture of the left first metacarpal shaft.
• Do not use this code for the initial treatment of an acute fracture; instead, use the appropriate acute fracture code from the S62.24- series.
