Nondisplaced Rolando's fracture, unsp hand, init for clos fx

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

Apply this code for the initial treatment of a patient presenting with a Rolando's fracture of an unspecified hand, where the fracture is confirmed to be closed (skin intact) and nondisplaced. This typically occurs following direct trauma to the thumb or a fall onto an outstretched hand.

• Ensure documentation specifies "nondisplaced" and "closed" for accurate code assignment.
• "Unspecified hand" should only be used if the medical record does not clearly indicate the left or right hand.
• This "A" suffix denotes an initial encounter for active treatment of the fracture.
