What Family (who is one of the kinder VJ members, in fact) is saying is that the consulate will not spoon-feed you the requirements to overcome this inadmissibility. Why? Well, because honestly that is not their job.
If he really does want to immigrate to the U.S., it is 100% your husband’s responsibility to figure out his next step by contacting the clinic where he had the medical exam.
Neither the clinic nor the United States consulate will be proactive about it- it’s entirely up to the applicant.
I'm sure it’s frustrating for you to be trying to do this on his behalf, but really he needs to step up and take an active role in this, since it is entirely down to his choices.
