She's now experienced what it's like to *not* have health care insurance and have a major healthcare event. If her income is extremely low, she'd qualify for medicaid (even with other assets),
many hospitals (and associated medical groups/providers) offer in-house financial assistance that have much higher income caps than medicaid (and don't consider assetts). i was very surprised when my oldest had very good insurance and a schedualed surgery to learn about these from the hospital rep at the pre-op appointment. we found that there was eligibility for a program that ended up wiping out all co-pays and the remainder of the deductible for the hospital and all the providers assocated. no way there was eligibilty for medicaid but the hospital's program had much more generous income caps (and they took into consideration what the anticipated income would being during a recovery period.
now, i have not worked inside the medicaid program for YEARS and different states have different programs but with mary lou's income source being very intermittent and not easily anticipated she could very likely be eligible. irregular income that cannot be reasonably anticipated (which i imagine speaking engagements easily fall under) are handled in entirely different manner.
