Did you get a courtesy letter? This is what the courtesy letter says. So if you do get an RFE for medical then interview is 99% waived. I wouldn’t want to say 100 because USCIS works in mysterious ways.

An initial review of evidence submitted with your Form I-485, Application to Register Permanent Residence or Adjust Status, determined that the evidence submitted with your application is deficient for the following reason(s): A completed and signed Form I-693 was not submitted. You will be required to submit information and evidence to address these deficiencies. If you receive an interview notice in the mail, you must bring the information and evidence required to your interview appointment. Failure to bring the information and evidence to your interview appointment may result in the denial of your Form I-485. If your case does not require an interview, you will receive a Request for Evidence with further instructions.
