This is really helpful guys thank you - but we are now quite confused about how to fill out the form!
We are sending them (they are the Overseas Patients Office at our hospital) an email with the recently paid IHS reference number and have been told over the phone that we can just email over supporting documents too along with the completed form. I plan to cite Section 3C too to help with the whole 'limbo' situation.
The thing is, I don't really understand what we need to fill out in this form. Attaching a link to images of the form I took:

We understand everything about the form APART from the following (naturally, there is no guidance from the office on how to fill out the form):
1. Page 1: OFFICIAL DOCUMENTATION - I think we should provide a Current Non-EU Passport (my wife's US passport), but should we tick 'visit visa' too and attach her expired BRP?
2. Page 2: do we fill in the "IN UK ON VISA" section, or the "IN UK TO LIVE PERMANENTLY" section? We don't know which applies to us haha, it feels like both?
3. Page 2: Assuming it's only the "IN UK TO LIVE PERMANENTLY" section, what is the difference between a Biometric Residence Permit and a Biometric Residence Card, should we tick one or both, and is it okay to send my wife's (now expired!) BRP card? And I assume that everywhere it says "passport" they are not necessarily looking for a British Passport, just ID, right?
We've got everything else covered we think, and we plan to re-iterate our situation of waiting for her new FLR(M) visa extension and her entitlement to free healthcare in that Section 3C you quoted, in the 'other circumstances' section on page 3.
Thanks in advance for your amazing help once again...
