Disp fx of neck of first metacarpal bone, unsp hand, sequela

This code signifies a fracture of the neck of the first metacarpal bone (thumb metacarpal) that is no longer in its anatomical alignment. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial injury, after the acute phase of treatment has concluded.

Use this code when documenting long-term effects, complications, or residual conditions directly attributable to a previously sustained displaced fracture of the first metacarpal neck. This includes scenarios like malunion, nonunion, chronic pain, or functional limitations stemming from the original injury. This code is appropriate for follow-up encounters after the initial healing period.

• Always ensure documentation clearly specifies "sequela" or a chronic condition resulting from the initial fracture.
• Do not use this code for the initial acute injury; a different code would be used for the active treatment phase.
• Verify laterality (left, right, or unspecified) is accurately reflected in the medical record.
