I’m getting continuous rejections from Medicare for DME products. For example, I’ve billied L4361(Walking Boot) with and without mod NU, RT/LT and without a modifier but Medicare denies the claim saying "procedure code is inconsistent with modifier used or a required modifier is missing". I just submitted the claim to DMERC with a KX mod in hopes that it gets paid.

Am I missing something?

Thanks in advance!
