10 assessments/50 testing hours per month seems very reasonable, but I'm not sure if that'd actually meet 2500 RVUs/year. I think the last time I looked at the numbers, a standard outpatient adult neuropsych would get you something like 13-14 RVUs per, although it might've been a bit higher. If that were the case, it'd work out to a total of about 192 evals/year, which is just under 4/week assuming a 52-work-week year, or 4/week assuming a 48-work-week year. Still not horrible, but definitely more than what they're quoting. Unless they're using different RVU numbers.
I've heard other folks on listservs mentioning an expectation around that number, although I don't recall what the consensus response was.
Edit: just checked, and yeah, if you did all of your own testing, with 2023's CMS numbers: If you used 96116 for the interview (90791 gives more RVUs, but I was too lazy to scroll down to find the value), and let's say you did 3 hours of testing, 2-3 hours of 96132/96133, and 1 hour of feedback (also 96133), you're looking at 13.6 to 15.6 RVUs per eval. Take off about 3 if not doing any of your own testing. Using the upper value, that's 160 evals/year, or 3.3 per week for a 48-week work year.
I suspect kiddo evals may be longer, but I dunno how many additional RVUs they'd net you.
