Oth disp fx of base of 1st MC bone, r hand, 7thG

This code describes a fracture of the base of the first metacarpal bone (thumb) in the right hand that is displaced, meaning the bone fragments are not properly aligned. 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.

This code is appropriate for documenting ongoing treatment for a right thumb metacarpal base fracture where the initial injury has already been addressed, but the healing process is prolonged. It would be used for patients presenting for follow-up appointments, cast changes, or imaging to assess the delayed union of the fracture.

• Ensure documentation clearly states "delayed healing" for this specific fracture.
• Verify the fracture is of the base of the first metacarpal and on the right hand.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
