S52.035B
ICD-10-CMNondisplaced fracture of olecranon process with intraarticular extension of left ulna, initial encounter for open fracture type I or II
This code describes a break in the prominent bony tip of the elbow (olecranon process) on the left arm. The fracture does not involve significant displacement of the bone fragments, but it extends into the elbow joint itself. This specific code is for an initial treatment encounter where the skin is broken, indicating an open fracture of either Type I or Type II severity.
Use this code for the initial treatment of a patient presenting with an open fracture of the left olecranon that extends into the joint, but where the bone fragments are still in their normal alignment. This typically occurs due to direct trauma to the elbow, such as a fall onto a flexed arm or a direct blow. The "open" nature implies a wound communicating with the fracture site, classified as Type I (small skin puncture) or Type II (moderate skin laceration with some muscle damage).
