Disp fx of shaft of first metacarpal bone, right hand, init

This code signifies a break in the main body (shaft) of the first metacarpal bone, located in the thumb of the right hand. The bone fragments are not properly aligned, indicating a displacement. This diagnosis is for the initial treatment of a fracture where the skin remains intact.

This code is appropriate for patients presenting with an acute, closed fracture of the right thumb's metacarpal shaft that is visibly or radiographically displaced. It should be used for the initial encounter for treatment, such as casting, splinting, or surgical repair. Do not use this code for subsequent care or open fractures.

• Ensure documentation clearly specifies "right hand" and "first metacarpal shaft" to support this code.
• Verify the fracture is explicitly described as "displaced" and "closed" in the medical record.
• The "A" suffix indicates an initial encounter for active treatment; select the appropriate subsequent encounter or sequela suffix for follow-up care.
