ICD-10-CMNondisplaced segmental fracture of shaft of humerus, unspecified arm, subsequent encounter for fracture with nonunion
This code describes a situation where a patient has a fracture in the shaft of their humerus (upper arm bone) that is broken in multiple places (segmental) but the bone fragments are still in their normal anatomical alignment (nondisplaced). The key aspect is that this is a subsequent encounter for a fracture that has failed to heal properly (nonunion).
This code is used when a patient presents for follow-up care of a previously diagnosed segmental humerus shaft fracture that has not united, and the fracture fragments remain in their correct position. This would apply to visits for ongoing management, evaluation for surgical intervention for nonunion, or conservative treatment of the nonunion.
