Heh, that's the problem the pre-certified modules.

As long as you do the certification for your own device, and design it
to use the appropriate (low) power, then you can have any OEM module
(that has adjustable TX power) within 20cm of the user.

But I'm not aware of any pre-certified OEM modules certified to be body worn.
