Disp fx of neck of first MC bone, right hand, sequela

This code signifies a long-term complication or late effect stemming from a previously displaced fracture of the neck of the first metacarpal bone (thumb) in the right hand. This indicates that the initial injury has healed, but the patient is now experiencing residual issues directly attributable to that specific fracture.

Apply this code when documenting conditions such as chronic pain, deformity, limited range of motion, nonunion, or malunion that are a direct consequence of a healed, displaced right first metacarpal neck fracture. This is appropriate for follow-up encounters where the sequela is the primary reason for the visit, rather than the acute fracture treatment.

• Always sequence this sequela code after the code for the specific sequela (e.g., M20.011 for Boutonnière deformity of right thumb).
• Ensure documentation clearly links the current condition to the previous displaced right first metacarpal neck fracture.
• Do not use this code for initial or subsequent encounters during the active treatment phase of the fracture.
