ICD-10-CMNondisplaced simple supracondylar fracture without intercondylar fracture of left humerus, subsequent encounter for fracture with nonunion
This code describes a left humerus fracture located above the condyles, which is a simple break that has not shifted out of place and does not involve the joint surface between the condyles. The "K" seventh character indicates that the fracture has failed to heal properly and is being treated for a nonunion during a subsequent encounter.
This code is appropriate for follow-up visits where a patient is being managed for a previously diagnosed nondisplaced simple supracondylar fracture of the left humerus that has not united. This includes situations where the physician is assessing the nonunion, planning further treatment, or providing ongoing care for the unhealed fracture.
