Nondisp transverse fx shaft of l ulna, 7thM

This code describes a specific type of fracture involving the shaft of the left ulna, where the break is straight across the bone (transverse) and the bone fragments are still in their normal alignment (nondisplaced). It also indicates that the initial injury was an open fracture (meaning the skin was broken) of either Type I or Type II severity, and that the fracture has failed to heal properly (nonunion).

This code is used when a patient presents for follow-up care of a previously sustained open transverse fracture of the left ulnar shaft that is not healing as expected. It is appropriate for subsequent encounters where the nonunion of an open Type I or II fracture is the primary focus of treatment or evaluation.

• Ensure documentation clearly specifies "nondisplaced," "transverse," "left ulna shaft," and "nonunion."
• Verify the initial injury was an open fracture, type I or II, as this is a critical component of the code.
• This code is for subsequent encounters; an initial encounter for this specific nonunion would use a different code.
