ICD-10-CMDisplaced oblique fracture of shaft of unspecified ulna, subsequent encounter for open fracture type IIIA, IIIB, or IIIC with delayed healing
This code describes a specific type of ulna fracture where the break is angled (oblique) and located in the shaft of the bone, but the exact side (left or right) is not documented. The fracture is open, meaning the bone has broken through the skin, and is classified as a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC). This particular code is used during a subsequent encounter when the healing process is taking longer than expected.
Use this code for follow-up visits or hospitalizations for a patient with a previously diagnosed severe open oblique shaft fracture of an unspecified ulna, when the documentation clearly indicates delayed healing. This applies when the initial treatment has been rendered and the patient is still in the healing phase, but progress is slower than anticipated.
