Nondisp fx of l tibial spin, 7thM

This code describes a situation where a patient has a left tibial spine fracture that is not displaced, meaning the bone fragments are still in their normal alignment. This specific code is used during a follow-up visit for an open fracture (where the bone broke through the skin) classified as type I or II, and the fracture has failed to heal properly (nonunion).

Apply this code for subsequent encounters when a patient with a previously diagnosed nondisplaced open type I or II fracture of the left tibial spine is being treated for nonunion. This would typically be used after initial treatment, during ongoing management of the unhealed fracture. It indicates that the fracture is not progressing to healing as expected.

• Ensure documentation clearly specifies "left" tibial spine and "nondisplaced" fracture.
• Verify the original injury was an "open fracture type I or II" and that "nonunion" is explicitly documented.
• This code is for subsequent encounters; do not use for the initial injury.
