Since your device contains a radio, an intentional radiator in FCC language, your best course would be to go back to your test lab and ask them to prepare a report showing compliance to the FCC regulations.
I have a similar issue to this. I have read this multiple times and correlated it with my own search.
1. As per the measurement standards in 47 CFR 15.31, an intentional radiator would have to test to ANSI C63.10-2013.
Electronic Code of Federal Regulations (eCFR)
2. FDA Guidance mentions this standard but is not a recognized consensus standard. In fact, if you search for C63.10 it shows C63.15 (which complements C63.10 as per the former's scope)
3. I have seen that recently FDA cleared devices have mentioned the FCC compliance statement of preapproved modules (tested by the telecommunications bureau) and not test their finished devices to ANSI standards.
My questions with respect to the discussions on this thread are:
1. If tested to IEC 60601-1-2 will ANSI C63.10 or ANSI C63.15 compliance be required given that FCC checks compliance as per 47 CFR 15.31? If yes, what tests are not covered in the former standard?
2. If you have a preapproved module whether there is anything specific in the module's certification that should be mentioned in order to meet FCC compliance without testing for ANSI C63.10
