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

This code signifies a non-displaced fracture of the base of the first metacarpal bone (thumb), specifically a Rolando's fracture, in the right hand. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "delayed healing" specifies that the bone is not mending at the expected rate.

Use this code for patients presenting for ongoing treatment of a right-hand Rolando's fracture that was previously diagnosed and is now showing signs of delayed union. This applies to situations where the fracture fragments remain in their anatomical position without significant displacement.

• Ensure documentation clearly states "right hand" and "nondisplaced" for accurate code assignment.
• Verify that the encounter is for follow-up care and not the initial treatment of the fracture.
• Look for physician notes explicitly mentioning "delayed healing" or "delayed union" to support this specificity.
