Good day.

I just want to make sure that I am coding this correctly so we can bill the insurance.

Procedure: Bilateral, Lumbar L-3, 4 and Lumbar L- 5 Dorsal Ramus Radiofrequency Nerve Ablation (RFNA) with Fluoroscopy for lumbar facet joint mediated pain.

64635 is used for RFNA. Since there are 3 bilateral nerve facets to be destroyed is this how I code this?

64635-50, 64636, 64636-59, 64636-59, 64636-59?
64635 For L and R L3 nerve
64636 and 64636-59 for L and R L4 nerve
then 64636-59, 64636-59 for L and R L5 nerve

The book says report the add-on codes twice for bilateral procedure and don't put modifier 50 to it. However I know that when you report a code more than once, you will need to add mod 59 right? But I'm not sure if this is correct since it will be reported more than twice.

Please I need feedback on this.

Thank you
