Final answer:
The payment system is called fee-for-service, where providers are reimbursed based on the cost of services. Dialysis facilities are paid based on the cost of dialysis treatment and drugs are billed separately.
Step-by-step explanation:
The payment system that changed payment to facilities for dialysis and then billing for drugs is called fee-for-service. In a fee-for-service system, medical care providers are reimbursed based on the cost of the services they provide. This means that dialysis facilities would be paid based on the cost of providing the dialysis treatment, and then the drugs used during the treatment would be billed separately. This system allows for more accurate tracking of costs and can help ensure that providers are appropriately compensated for their services.
