S42.213P
ICD-10-CMUnspecified displaced fracture of surgical neck of unspecified humerus, subsequent encounter for fracture with malunion
This code signifies an unspecified displaced fracture of the surgical neck of the humerus that has not healed correctly (malunion). The "unspecified" nature means the laterality (left or right) is not documented, and the "subsequent encounter" indicates the patient is receiving routine care during the healing phase.
This code is appropriate for follow-up visits where a patient is being managed for a malunion of a surgical neck humerus fracture, and the specific side of the body is not documented. This would include scenarios like cast changes, wound checks, or physical therapy evaluations during the malunion treatment period.
