Nondisp fx of shaft of 1st MC bone, l hand, 7thG

This code signifies a break in the main body of the thumb metacarpal bone on the left hand that is still healing, but not as quickly as expected. The bone fragments remain in their normal alignment, meaning no surgical reduction was required to realign them.

Apply this code for follow-up encounters where a patient is being treated for a left first metacarpal shaft fracture that is demonstrating delayed union. This is appropriate when the fracture has not fully consolidated within the expected timeframe for healing.

• Ensure documentation specifies "left hand" and "first metacarpal shaft" to support this code.
• The "G" seventh character indicates a subsequent encounter for a fracture with delayed healing, so verify the patient is past the initial treatment phase.
• Confirm the fracture is explicitly documented as "nondisplaced" to differentiate from displaced fractures.
