Hello, needing direction on whether or not you submit the vaccine on your claim to MCO's (TN specifically) with administration code and SL modifier, or is the SL modifier added to the vaccine code as well or do you just submit the admin code with SL modifier on the claim and leave the vaccine off the claim? Where do you find support for how you might do this? Any direction/suggestions are greatly appreciated. We have this discussion in our office every other month and each MCO adjudicates these claims differently.
