Another frequent problem that the doctors were running into with the ACA is that the doctor's office would call for confirmation of coverage, and if the patient had applied for a policy, the coverage was confirmed, so the doctor accepted the coverage and performed the services.  But the ACA was allowing a 90-day grace period to pay the initial premium, and if it wasn't paid ... as it often wasn't ... the claim from the doctor was denied, stiffing him/her for the entire bill.

The ACA has had an adversarial relationship with the health care providers, who are, after all, people exchanging their labor and property for money.  If you think you have a "right" to their services and property without their agreement on compensation, you believe in a return to slavery.
