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

This code signifies a fracture at the base of the first metacarpal bone (thumb) in the right hand, which is not displaced. The injury is currently in a phase of delayed healing, indicating that the bone is taking longer than expected to mend.

Apply this code when documenting follow-up care for a right thumb metacarpal base fracture that was initially nondisplaced, and the physician notes that the healing process is prolonged. This would be used for subsequent encounters after the initial treatment, where delayed union is the primary concern.

• Ensure documentation explicitly states "nondisplaced" and "delayed healing" for the right first metacarpal base.
• This code is for subsequent encounters; an initial encounter would use a different 7th character.
• Verify laterality (right hand) is clearly documented.
