I've Got A Bad Case Of Mistrusting You

AITOOW wonders if doctors are purposely misdiagnosing  patient data to make them seem sicker so the insurance companies can characterize them as more risky and increase their costs? I swear my doctor is saying I'm shorter and fatter than I actually am to change my BMI designation. Plus I think she doesn't measure my blood pressure properly. And she claims I need vitamin d with no test confirmation. And these are just a few, innocuous, examples of possible manipulation. It could just be poor machinery or sloppy work, but, would you put it past them?
