I code for a neurosurgeon that wants to submit 22633 and 22612 during the same surgical session. Is it appropriate to bill these 2 primary procedures together? I was thinking no and that each additional level without an interbody fusion would be 22614.

For example:
Right L4-5 TLIF
L3 to L5 posterolateral arthrodesis

I would submit this as:
22633
22614

Should I be using: 22633 and 22612??

Please help!! I appreciate your time.
