Sometimes at work I just want to pull a Clippy and be like, "it looks like you're trying to test this patient for vitamin D deficiency! I say that because the diagnosis code you used is 'Screening for Vitamin D deficiency'! But the test you asked for is Vitamin D dihydroxy (not to be used for vitamin D deficiency screening). Did you mean to ask for the much more common and less expensive test, Vitamin D 25 hydroxy, instead?"

But no, we're not supposed to fill out a follow up request if a doctor explicitly asked for the test, which they did.

Hey, this is a great example how American healthcare is wildy inefficient and riddled with errors!
