Nondisp spiral fx shaft of ulna, unsp arm, 7thQ

This code describes a situation where a patient has a non-displaced spiral fracture in the shaft of their ulna, but the specific arm (left or right) is not documented. This particular encounter is for follow-up care of an open fracture (Type I or II) that has healed incorrectly, resulting in a malunion.

Use this code for subsequent encounters when a patient is being treated for complications of a previously sustained open spiral ulna shaft fracture that has malunited. This applies when the laterality of the arm is not specified in the medical record. This code is appropriate when the initial injury was an open fracture type I or II.

• Ensure documentation clearly states "malunion" as the complication of the fracture healing.
• Verify the original fracture was an open fracture, specifically Type I or II, as this impacts the 7th character.
• Only use this code when the medical record does not specify whether the left or right arm was affected.
