Nondisp fx of unsp tibial spin, 7thN

This code describes a fracture of the tibial spine that has not shifted out of alignment, specifically when the patient is receiving ongoing care for a severe open fracture (Type IIIA, IIIB, or IIIC) that has failed to heal properly. The tibial spine refers to the intercondylar eminence of the tibia, a critical area for knee stability. "Nonunion" indicates that the bone ends have not united after the expected healing period.

Apply this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced tibial spine fracture, where the initial injury was a severe open fracture. This is appropriate for encounters where the focus is on managing the nonunion, such as during clinic visits for assessment, treatment planning, or monitoring of healing progress.

• Ensure documentation clearly specifies "nondisplaced" and "unspecified tibial spine."
• Verify the original injury was an open fracture classified as Type IIIA, IIIB, or IIIC.
• Confirm that the encounter is for subsequent care related to the nonunion, not initial treatment.
