I know Spooky is more likely to be correct as she is a CDC. But my friend does 810 and didn't have to get a medical form signed despite having a starting BMI of 46. She did discuss it at the time with her CDC and was told it was only if doing the VLCD that the form had to be signed not the 810 which is a LCD. Possibly just an oversight or miscommunication, but thought I would mention it. Either way, she got away without having a form signed then... oops.
