Disp fx of neck of fourth MC bone, left hand, sequela

This code signifies a long-term complication or late effect arising from a previously sustained displaced fracture of the neck of the fourth metacarpal bone in the left hand. It indicates that the initial injury has healed, but the patient is now experiencing residual issues directly attributable to that fracture.

This code is appropriate for documenting conditions such as chronic pain, malunion, nonunion, limited range of motion, or deformity of the left fourth metacarpal, occurring after the initial healing period of a displaced fracture. It should be used when the patient is seen for follow-up care related to these persistent problems.

• Always use this code as a secondary diagnosis, following a code that describes the specific sequela (e.g., M25.542 for chronic pain in left hand).
• Ensure documentation clearly links the current condition to the previous displaced fracture of the left fourth metacarpal neck.
• Do not use this code for initial or subsequent encounters for the acute fracture itself; those require codes from the S62.335A-R series.
