Is the debt of a patient who left the hospital due to inability to pay for the cost of surgery waived?

The costs of the operation are a debt upon the patient, to be repaid when he is able. If it is paid by a donor, his responsibility is cleared. Leaving the hospital without permission to evade payment is not permissible. He should have informed the administration of his inability. He must pay the remaining amount of the fee whenever he can, and this remains a debt upon him until it is waived due to inability or absolution from the creditor.
