I have so far elected to self-insure, i.e., to just pay any medical bills I might have out of pocket. However, given this "sucker rate" and the increasing unwillingness of hospitals to take patients not in health care or insurance programs, I may have little choice but to sign up.
Why not establish an offshore insurance company (e.g., in the Caribbean so the area code doesn't make it appear outside our boarders) which knows you true ID, but let's you use a pre-agreed upon pseudo-ID. They could even have URLs on their pages to services which could help you out obtaining realistic hardcopy. Doctors don't much care as long as they are getting paid and all will accept out-of-state, many even knowingly out-of-the-country, insurers. They really don't care about the IDs as long as they match something insurance company says they'll pay. --Steve
