Nondisp Rolando's fracture, l hand, subs for fx w delay heal

This code signifies a fracture of the base of the thumb metacarpal on the left hand, specifically a Rolando's fracture, which is comminuted (involving multiple fragments). "Nondisplaced" indicates the bone fragments are still in their anatomical alignment. The "subsequent encounter with delayed healing" specifies that this is not the initial treatment for the fracture, and the healing process is taking longer than expected.

This code is appropriate for follow-up visits where a patient is being monitored for a previously diagnosed nondisplaced Rolando's fracture of the left hand, and the physician notes that the fracture is not healing at the anticipated rate. It would be used when the patient is still receiving active treatment or evaluation for the delayed healing, such as repeat imaging or adjustments to immobilization.

• Always confirm laterality (left hand) and the specific type of fracture (Rolando's, nondisplaced).
• Ensure documentation clearly supports "delayed healing" for a subsequent encounter, not routine follow-up or initial treatment.
• Pair with appropriate procedure codes for any interventions performed during the encounter related to the delayed healing.
