2-part disp fx of surgical neck of unsp humerus, sequela

This code signifies a long-term complication or late effect stemming from a prior two-part fracture of the surgical neck of the humerus, where the bone fragments were out of alignment. It indicates that the patient is experiencing ongoing issues directly attributable to that healed or healing fracture, rather than an acute injury.

Apply this code when documenting a patient presenting with chronic pain, limited range of motion, nonunion, malunion, or other persistent functional deficits directly linked to a previously sustained displaced two-part surgical neck humerus fracture. This code is appropriate for follow-up encounters after the initial healing phase, where the sequela is the primary reason for the visit.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., M25.51_ for pain in shoulder).
• Ensure documentation clearly links the current condition to the prior surgical neck fracture.
• Verify laterality (left, right, or unspecified) is consistent with the patient's medical record.
