cpt billing rt occipitoatlantal and atlantoaxial joint injection

Mike Posted Tue 15th of October, 2013 10:41:40 AM

procedures done :
LF C2-C3 , LF C3-C4 , RT occipitoatlanta joint and RT atlantoaxial joint injections- for a total of 4 injections.

I get confused with how to code the OA and AA joints because of the location.

This is what I think 64490 (C2-C3), 64491 (C3-C4) and 64492 (OA and AA joints). Is this a correct interpretation?

Occipitoatlantal Joint / Atlanto-occipital joint (articulation between the atlas and the occipital bone) --> C0-C1
Atlantoaxial Jt --> C1-C2

So there are 4 paravertebral factet joint levels. Injections are given at these levels. I would go with:

64490 --> for C0-C1
+ 64491 --> for C1-C2
+64492 --> for C2-C3 , C3-C4
