A recent article indicated that there has been an 18% decrease in the amount of medical debts that are being reported on credit bureaus. This is due in part to new policies whereby medical debts under $500 are no longer being reported to the credit bureaus, nor are medical debts that have been paid.
Unlike revolving debts such as credit cards, medical bills are often not reported to credit bureaus.
Apparently the Biden administration has claimed responsibility for this reduction as well, because Obamacare made more people insured or insurable. (My experience, as a self-employed person, was that Obamacare made my health insurance go through the roof, which is why I was fortunate my wife got a job with a school.)
