Type III occipital condyle fracture, unspecified side, 7thK

This code signifies a complex fracture of the occipital condyle, specifically a Type III injury, which involves an avulsion fracture from the basion. The "unspecified side" indicates that the laterality of the fracture is not documented. The "subsequent encounter with nonunion" specifies that this is a follow-up visit for a previously diagnosed fracture that has failed to heal properly.

Use this code for a patient presenting for ongoing management of a Type III occipital condyle fracture where the side is not specified, and the physician documents nonunion of the fracture. This would typically be seen in follow-up appointments after initial treatment, where imaging or clinical assessment confirms the lack of bone healing. Documentation should clearly state "nonunion" and the Type III classification.

• Ensure documentation explicitly states "nonunion" for the subsequent encounter.
• Verify the fracture type is indeed Type III (avulsion from basion); other occipital condyle fracture types have different codes.
• If the laterality (left or right) is specified in the documentation, a more specific code should be used instead of "unspecified side."
