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

This code signifies a past fracture of the base of the fourth metacarpal bone in the left hand, which was displaced at the time of injury. The "sequela" designation indicates that the patient is currently experiencing a residual condition or complication directly related to this old fracture.

This code is appropriate when a patient presents with a long-term problem, such as chronic pain, deformity, limited range of motion, or nonunion, that is a direct consequence of a previously sustained and healed (or healing) displaced fracture of the base of the left fourth metacarpal. It should be used after the initial healing phase of the fracture is complete.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the old displaced fracture of the left fourth metacarpal base.
• Do not use this code for initial or subsequent encounters during the active treatment of the acute fracture.
