Someone corrected you on this further up in the thread, but you are again repeating it. For studies less than two hours, a patient qualifies for a Medicare diagnosis if:
1. There occurs 30 or more respiratory disturbances.
or
2. There occurs 10 respiratory disturbances with documented symptoms of excessive daytime sleepiness, impaired cognition, mood disorders or insomnia, or documented hypertension, ischemic heart disease, or history of stroke.
#2 makes the requirement very relaxed since most people have one or more of those symptoms and quickly rack up 10 RDs.
