Nondisp transverse fx shaft of humer, unsp arm, 7thP

This code signifies a transverse fracture of the humeral shaft that was initially nondisplaced but has since healed in an unsatisfactory alignment (malunion). The injury involves the long, central part of the upper arm bone, and the specific arm affected is not documented.

This code is appropriate for follow-up encounters where a patient is being treated for complications arising from a previously sustained nondisplaced transverse humeral shaft fracture that has healed with malunion. This could include assessment for pain, limited range of motion, or functional impairment due to the altered bone alignment. It is used when the fracture is no longer acute but the malunion is the focus of the current visit.

• Ensure documentation clearly states "malunion" and specifies the fracture as "transverse" and "nondisplaced" initially.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
• If the specific arm (left or right) is known, a more specific code should be used instead of "unspecified arm."
