Displ Rolando's fx, unsp hand, subs for fx w delay heal

This code signifies a fracture of the base of the first metacarpal bone (thumb) that has separated from its normal alignment and is currently in a phase of delayed healing. A Rolando's fracture is a comminuted intra-articular fracture, meaning it involves multiple fragments and extends into the joint surface. The "unspecified hand" indicates the laterality is not documented.

Apply this code when a patient presents for follow-up care of a previously diagnosed and treated displaced Rolando's fracture of the thumb, and the physician's documentation explicitly states that the fracture is experiencing delayed healing. This code is appropriate for subsequent encounters after the initial treatment, such as cast changes, physical therapy, or re-evaluation of healing progress.

• Ensure documentation clearly specifies "delayed healing" for a subsequent encounter.
• Verify the fracture is indeed a Rolando's fracture and not a Bennett's fracture, as these are distinct.
• If the laterality (left or right hand) is known, a more specific code should be used.
