ICD-10-CMDisplaced simple supracondylar fracture without intercondylar fracture of left humerus, subsequent encounter for fracture with nonunion
This code signifies a specific type of upper arm bone fracture in the left arm, located just above the elbow joint, that has not healed properly. It's a "simple" fracture, meaning the bone is broken in two pieces without additional fragmentation, and it does not extend between the condyles (the rounded prominences at the end of the bone). The "nonunion" indicates that the fracture fragments have failed to unite after the expected healing period.
Use this code for follow-up encounters where a patient is being treated for a previously diagnosed displaced simple supracondylar fracture of the left humerus, and the physician has documented that the fracture has not achieved bony union. This applies to ongoing management, such as further surgical intervention for nonunion, casting changes, or physical therapy related to the nonunion.
