Does anyone know of any medicare chages as to why they are denying the 3rd level for facet injections? Is medicare requireing a modifier now. We are billing 64493, 64494 and 64494 again for the 3rd level. Medicare is only paying the 1sr 2 and denying the 3rd. Any suggestions or info would be helpful.
 
We have the same problem with other insurances & Medicare. As long as there is documentation to back it up, we submit with a -59 modifier on the 2nd 64484 then the lateral modifiers of -LT or -RT and we always get paid.
 
ASC. medicare says they need to be billed as units on one line, which is fine if it's only one side, but for the bilat procedures medicare has not accepted the 50 modifier in the past. we just sent in a claim with the 50 mod and 2 units with an adj to the amount and will see what happens. you would think when medicare makes a change like this they would put it out there somewhere. When we called they said this was put in place as of july 1st, but I did not see it anywhere or get any updates from medicare about this change.
 
I'm in Southern California, so I don't know if it's same or different in each regions. We've billed the 64483, 64484 (ea. line) with no modifier other than -LT/-RT and the 2nd 64484 was always denied. so we had to go back & add the modifier, then we were paid.

ODG offers the following including only two levels in one session....

Criteria for the use of diagnostic blocks for facet “mediated” pain:
Clinical presentation should be consistent with facet joint pain, signs & symptoms.
1. One set of diagnostic medial branch blocks is required with a response of ≥ 70%. The pain response should last at least 2 hours for Lidocaine.
2. Limited to patients with low-back pain that is non-radicular and at no more than two levels bilaterally.
3. There is documentation of failure of conservative treatment (including home exercise, PT and NSAIDs) prior to the procedure for at least 4-6 weeks.
4. No more than 2 facet joint levels are injected in one session (see above for medial branch block levels).
5. Recommended volume of no more than 0.5 cc of injectate is given to each joint.
6. No pain medication from home should be taken for at least 4 hours prior to the diagnostic block and for 4 to 6 hours afterward.
