ICD-10-CMDisplaced fracture of coronoid process of left ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
This code signifies a fracture of the coronoid process, a bony projection on the ulna in the elbow, specifically on the left side. The fracture is displaced, meaning the bone fragments are not properly aligned. This particular code is used when the patient is in a later stage of healing for an open fracture (where the bone broke through the skin) classified as Type IIIA, IIIB, or IIIC, and the healing process is taking longer than expected.
Use this code for follow-up encounters when a patient with a previously diagnosed displaced open coronoid process fracture of the left ulna (Type IIIA, IIIB, or IIIC) is presenting for ongoing management due to delayed healing. This would include scenarios where the fracture site is not consolidating as anticipated, requiring continued medical intervention or monitoring.
