Disp fx of base of fifth MC bone, right hand, sequela

This code signifies a fracture at the base of the fifth metacarpal bone in the right hand that was displaced at the time of injury, and the patient is now presenting with a sequela (a late effect or complication) of that original fracture. Sequelae can include chronic pain, nonunion, malunion, deformity, or restricted range of motion directly attributable to the past fracture.

Use this code when documenting a patient encounter for a long-term complication or residual condition stemming from a previously sustained displaced fracture of the base of the right fifth metacarpal. This applies to follow-up visits occurring after the initial healing period, where the focus is on managing the chronic effects of the injury.

• Always assign an additional code to specify the nature of the sequela (e.g., M25.541 for chronic pain in the right hand, M84.454A for malunion of the right hand).
• Ensure documentation clearly links the current condition to the historical displaced fracture of the right fifth metacarpal base.
• Do not use this code for initial treatment of the acute fracture or for routine follow-up during the healing phase.
