ICD-10-CMNondisplaced comminuted supracondylar fracture without intercondylar fracture of unspecified humerus, subsequent encounter for fracture with delayed healing
This code describes a supracondylar fracture of the humerus that is broken into multiple pieces (comminuted) but remains in its anatomical position (nondisplaced). It specifically excludes involvement of the intercondylar region and is used when the fracture is not healing as expected during a follow-up visit.
This code is appropriate for documenting a patient's follow-up visit for a supracondylar humeral fracture that is showing signs of delayed union. It would be used after the initial treatment phase, when the provider is monitoring healing progress and notes that it is slower than anticipated.
