Hallo placement

LOCATION: Outpatient, Hospital
PATIENT:
SURGEON:PREOPERATIVE DIAGNOSIS: Fracture of CI, C2
POSTOPERATIVE DIAGNOSIS: Fracture of CI. C2
PROCEDURE PERFORMED: Placement of a halo
INDICATION: Fracture occurred when the patient was involved in an unspecified motor vehicle collision. It is known that the patient was the driver of the vehicle.
PROCEDURE: The patient's head was prepped and draped in the usual manner. The head was shaved. The halo apparatus was applied with screws and four-points. Then the vest was applied. The patient was then discharged to the recovery room to have films taken in the recovery room.

How would I look up the procedure? What main term would I use to look up in the CPT-4 index to code the procedure?

For the ICD-9-CM codes am I correct with 805.01, 805.02, and E812.0?

Thanks for all the help; I'm new at this and still learning.
