I just received a bunch of denials for testing that we billed in 2019 with the new psychological testing codes. The codes we typically use are 96130, 96131, 96136, and 96137. Medicare is denying the claims saying 'missing/incomplete/invalid provider primary identifier' and 'missing/incomplete/invalid referring provider identifier'. I know that neuropsychological testing always required the referring physician and NPI#, but psychological testing never did. None of the codes I mentioned are neuropsych testing (as far as I know....unless, I am unaware of something obvious) so I am very confused! Any thoughts or experience with this?
