ICD-10-CMNondisplaced spiral fracture of shaft of humerus, left arm, subsequent encounter for fracture with nonunion
This code describes a left humerus shaft fracture that is spiral in nature and has not shifted out of alignment. The fracture is in a healing phase, but complications have arisen where the bone is failing to unite properly.
This code is appropriate for follow-up encounters where a patient is being treated for a left humeral shaft spiral fracture that has not healed as expected, resulting in nonunion. It indicates ongoing management of this specific fracture complication.
