Our LCD for Medicare for RF's states "generally no more than three levels of injections will be allowed unless acceptable medical necesity can be demonstrated". Our doctors will do 3 levels...l3-4 l4-5 and l5-s1 and bill 64622 and 64623 (x3) and we never get paid but for 3. The docs say they have to burn 4 nerves when doing 3 levels. Any feedback would be greatly appreciated!!
