Nondisplaced Rolando's fracture, right hand, init

This code signifies a fracture of the base of the first metacarpal bone (thumb) that extends into the carpometacarpal joint, without displacement of the bone fragments. It is a comminuted fracture, meaning the bone is broken into multiple pieces, and is considered a more severe variant of a Bennett's fracture.

This code is appropriate for the initial encounter of a patient presenting with a newly diagnosed Rolando's fracture of the right thumb, where the skin over the fracture site remains intact. It is used when the fracture fragments are in their anatomical position and have not shifted.

• Ensure documentation specifies "nondisplaced" and "right hand" for accurate code assignment.
• Verify that the encounter is the initial treatment for the fracture.
• Confirm the fracture is closed; if open, a different code would be necessary.
