Disp fx of base of second MC bone, left hand, sequela

This code signifies a past injury involving a break at the base of the second metacarpal bone in the left hand, which was displaced at the time of the fracture. The "sequela" designation indicates that the patient is currently experiencing a late effect or complication directly resulting from this old fracture. This could include chronic pain, limited range of motion, nonunion, malunion, or other long-term issues.

This code is appropriate when a patient presents with a current condition or symptom that is a direct consequence of a previously sustained, displaced fracture of the base of the left second metacarpal. It should be used for follow-up encounters where the primary reason for the visit is to address the long-term effects of the old injury, not the acute fracture itself. This code would be assigned after the initial healing period of the acute fracture has passed.

• Always assign an additional code to specify the nature of the sequela (e.g., chronic pain, malunion, nonunion).
• Do not use this code for an acute fracture; use the appropriate acute fracture code from the S62.311 series for initial and subsequent encounters during the active treatment phase.
• Ensure documentation clearly links the current condition to the old displaced fracture of the left second metacarpal base.
