Oth disp fx of base of first MC bone, unsp hand, init

This code signifies a fracture at the base of the thumb's first metacarpal bone that is not aligned correctly (displaced). The specific type of fracture is not further detailed, and the affected hand is not specified. This code is used for the initial treatment of a closed fracture, meaning the skin remains intact.

This code is appropriate for documenting the initial encounter for a patient presenting with a displaced fracture at the base of the first metacarpal bone, where the specific type of fracture (e.g., Bennett's, Rolando's) is not yet determined or documented. It applies when the fracture is closed and the affected hand is not specified in the medical record.

• Ensure the documentation specifies "displaced" and "base of first metacarpal" to support this code.
• Verify that the encounter is for the initial treatment of the fracture, indicated by the "A" seventh character.
• If the specific hand (left or right) is documented, a more specific code should be used.
