(a) Operator liability. If an operator has been determined liable for the payment of benefits to a miner, OWCP will notify the operator or its insurance carrier of the names, addresses, and telephone numbers of the authorized providers of medical benefits chosen by an entitled miner, and require the operator or carrier to:
(1) Notify the miner and the providers chosen that the operator or carrier will be responsible for the cost of medical services provided to the miner on account of the miner's total disability due to pneumoconiosis;
(2) Designate a person or persons with decision-making authority with whom OWCP, the miner and authorized providers may communicate on matters involving medical benefits provided under this subpart and notify OWCP, the miner and providers of this designation;
(3) Make arrangements for the direct reimbursement of providers for their services.
(b) Fund liability. If there is no operator found liable for the payment of benefits, OWCP will make necessary arrangements to provide medical care to the miner, notify the miner and providers selected of the liability of the fund, designate a person or persons with whom the miner or provider may communicate on matters relating to medical care, and make arrangements for the direct reimbursement of the medical provider.
