Nondisp fx of shaft of first MC bone, unsp hand, sequela

This code indicates a healed or residual condition resulting from a fracture of the main body (shaft) of the first metacarpal bone (thumb) that was not displaced at the time of injury. The specific hand affected is not documented.

Apply this code when documenting a long-term effect or complication of a previously sustained, nondisplaced shaft fracture of the first metacarpal. This is appropriate for follow-up visits after the initial healing phase, or when a patient presents with ongoing symptoms directly attributable to the old fracture.

• Requires a seventh character of 'S' to denote sequela, indicating a late effect.
• Do not use for initial or subsequent encounters for active treatment of the fracture.
• Consider using an additional code to specify any persistent symptoms or complications, such as pain or limited range of motion.
