Nondisp spiral fx shaft of rad, unsp arm, 7thP

This code describes a spiral fracture of the shaft of the radius that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The fracture is located in an unspecified arm and is being treated in a subsequent encounter where the fracture has healed incorrectly, resulting in malunion.

Use this code for follow-up visits or ongoing care for a patient who previously sustained a nondisplaced spiral fracture of the radial shaft, and imaging or clinical assessment now confirms that the fracture has healed in a deformed or misaligned position (malunion). This code is appropriate when the specific arm (left or right) is not documented.

• Ensure documentation clearly states "nondisplaced spiral fracture of shaft of radius" and "malunion."
• Verify that the encounter is for follow-up care related to the malunion, not the initial treatment.
• If the arm is specified (left or right), a more specific code from the S52.34- series should be used.
