| 650 | OBSOLETE DATA REVIEWED AND CHANGED V0200 In CSv1 extension to the orbit was included in both codes 650 and 700. In addition the instructions for coding invasion of orbital bone were not clear. Codes 650 and 700 should be reviewed for orbital involvement. Involvement of bone of floor of orbit should be coded 760, and other orbit involvement should be coded 790. Orbit | ERROR | ERROR | ERROR | ERROR |
