Unsp fx the low end unsp rad, 7thN

This code signifies a non-union of an unspecified fracture of the lower radius, which was initially an open fracture classified as Type IIIA, IIIB, or IIIC. It indicates that the patient is in a subsequent phase of care, where the fracture has failed to heal properly. The "unspecified" nature refers to the lack of further detail regarding the specific type of lower radius fracture.

Use this code when documenting follow-up care for a patient with a previously diagnosed open fracture (Type IIIA, IIIB, or IIIC) of the distal radius that has not achieved bony union. This applies to situations where the specific type of distal radius fracture (e.g., Colles, Smith) is not documented or is unknown. This code is appropriate for ongoing management of the non-union, such as during surgical planning for revision or continued conservative treatment.

• Ensure documentation clearly states "nonunion" and specifies the initial fracture as an open fracture Type IIIA, IIIB, or IIIC.
• This code is for subsequent encounters; an initial encounter code would have been used for the acute injury.
• Verify that the laterality (left, right, or bilateral) of the radius fracture is truly unspecified in the medical record before using this code.
