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

This code signifies a nondisplaced fracture of the base of the thumb metacarpal (Rolando's fracture) in an unspecified hand, which is currently experiencing delayed healing. It indicates that the initial treatment has occurred, but the bone union is not progressing at the expected rate.

Apply this code when a patient presents for follow-up care of a Rolando's fracture where imaging or clinical assessment confirms delayed healing. This would typically be used after the initial encounter for the fracture and before definitive healing or nonunion is established.

• Ensure documentation specifies "delayed healing" for the Rolando's fracture; otherwise, a routine subsequent encounter code may be more appropriate.
• Verify the laterality (left, right, or unspecified) of the hand is clearly documented to ensure the most specific code is selected.
• Distinguish from "nonunion" (K) or "malunion" (P) which represent different stages of healing complications.
