Disp fx of proximal phalanx of left thumb, sequela

This code describes a fracture of the proximal phalanx of the left thumb that has healed but has resulted in a lasting complication or condition. This could include chronic pain, limited range of motion, malunion, nonunion, or other long-term effects directly attributable to the original fracture.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a previously sustained displaced fracture of the proximal phalanx of the left thumb. This applies to follow-up visits where the focus is on managing these long-term effects, rather than the acute treatment of the initial injury.

• Always sequence this code after the code for the specific sequela (e.g., M25.542 for chronic pain in left hand).
• Ensure documentation clearly links the current condition to the past displaced fracture of the left thumb's proximal phalanx.
• Do not use for initial or subsequent encounters for the active treatment of the acute fracture.
