Nondisp fx of nk of 1st MC bone, l hand, 7thP

This code describes a specific type of healing complication for a fracture in the left hand. It indicates that the patient previously sustained a fracture to the neck of the first metacarpal bone (thumb metacarpal) which was initially nondisplaced, but is now healing with malunion. Malunion means the bone has healed, but in an unsatisfactory or deformed position.

Use this code for follow-up encounters when a patient's previously sustained nondisplaced fracture of the neck of the left first metacarpal is documented as having healed, but with evidence of malunion. This applies when the patient is still receiving care related to the malunion, such as for pain, functional limitations, or consideration of corrective procedures. It is used after the initial healing phase has concluded.

• Ensure documentation clearly specifies "malunion" and not "nonunion" (which has a different code series).
• Verify the laterality (left hand) and the specific bone and location (neck of first metacarpal).
• Confirm this is a subsequent encounter for the fracture, indicating ongoing care related to the malunion.
