If the Authority modifies the request of a hospital for a change in its rates so that the hospital obtains only a partial increase in its rate schedule, the hospital shall have the right to accept the benefits of the partial increase in rates and charge its purchasers and third-party payors accordingly without in any way adversely affecting or waiving its right to contest or appeal that portion of the final order of the Authority which denied the remainder of the requested rate increase. Similarly, if an affected party contests or appeals the final order of the Authority, the hospital may charge its purchasers in accordance with the Authority's final order until the final order is subsequently modified.
