This is an appeal by the West Virginia Insurance Commissioner, hereinafter referred to as the Commissioner, from a final judgment of the Circuit Court of Kanawha County entered June 18, 1973 wherein the Circuit Court ordered the Commissioner to approve the rate filing application made by Blue Cross Hospital Service, Inc., hereinafter referred to as Blue Cross. The Commissioner contends that the proposed rates are excessive, and, therefore the application should not be approved. The Commissioner prays that the judgment of the Circuit Court be reversed and Blue Cross be directed to refund all additional premiums collected from its subscribers as a result of the rate increase ordered by the Circuit Court. This Court granted the Commissioner’s appeal on March 18, 1974 and the case was submitted for decision on January 21, 1975 upon the briefs and oral arguments on behalf of the parties and an amicus curiae brief filed on behalf of the twenty-six participating hospitals.
On April 4, 1972 Blue Cross filed for a rate increase with the Commissioner. On May 17, 1972 the Commissioner disapproved the proposed rates, and pursuant to a written demand by Blue Cross public hearings were held on September 13, 1972 and September 27, 1972. The Commissioner contended that the proposed rate increase was not justified because of inefficiencies in Blue Cross administrative and investment policies, and because its reimbursement contracts with the various hospitals *727were not in the best interests of Blue Cross subscribers. The Commissioner listed six objections why the proposed rate increase should not be granted: (1) several members of the Board of Trustees were also hospital administrators and thus inherent conflicts of interests were present during the negotiation of hospital reimbursement contracts, (2) Blue Cross reimbursed hospitals for services afforded subscribers in accordance with a formula wherein hospital charges bore no reasonable relationship to costs, (3) there were inefficiencies in the administration of subscriber claims, including unnecessary reimbursements to hospitals, (4) there were inefficiencies in the internal operations of Blue Cross, including the absence of standing committees within the board and inefficiencies in the electronic data processing system, (5) the management engaged in poor financial investment practices partly because of conflicts of interest, and (6) the schedule of fees to be paid to the hospitals was actuarily unsound.
Blue Cross properly assumed the burden of proof and introduced evidence at the hearing before the Commissioner which substantiated its position that a rate increase was needed. An actuary who testified on behalf of Blue Cross at the hearing stated the proposed rates were not excessive, and if not approved, Blue Cross would be insolvent by the middle of 1973. Other evidence was introduced that the current rates were inadequate. Evidence was introduced that Blue Cross administrative expenses were less than the average of all Blue Cross Plans throughout the country. The evidence indicated that the rates charged by the Charleston Blue Cross were less than those charged by Wheeling Blue Cross, although Wheeling’s reimbursement contracts had a ceiling of 115% on the ratio of hospital charges to costs, whereas, the average ratio of hospital charges to costs of the Charleston Plan was 129% for those hospitals from which such information was obtained.
The Commissioner introduced into evidence a report prepared by the Blue Cross Association, the national organization representing Blue Cross Plans, which was *728requested by Blue Cross to make a study of its operations. This three week study produced a detailed written report which recommended that several changes be made in the local Blue Cross operations. The report stated that the Charleston Plan was an average plan, but was critical in some aspects, and made recommendations for the improvement of the services, some of which had been implemented before the hearing was held by the Commissioner. The reimbursement contracts between the hospitals and Blue Cross, which were negotiated in 1970, provided for the payment by Blue Cross of 93% of the charges for the first year, and 97% for future years. The Blue Cross director stated that the new contract was not as good as the old one, but testified that it took eight months to obtain a new contract and that the present contract was the best contract to which the hospitals would agree.
It is the contention of the Commissioner that he had the right to go beyond the mere mathematical calculations of the rate application, and to determine whether inefficiencies in Blue Cross operations were resulting in higher costs which in turn increased the rate base from which the proposed rate increase was calculated. Additionally, the Commissioner argues that the reimbursement contracts with the hospitals should stipulate that there be a reasonable relationship of the hospitals’ charges to the hospitals’ actual costs, since hospital charges were shown to be excessive by the fact that the Blue Cross Association report showed that the average ratio of billed charges to hospital costs was 129%. The report recommended that in order to adequately protect the interest of the subscribers to the Blue Cross Plan, there should be effective measures taken to assure that the charges by the hospitals have a reasonable relationship to the hospitals’ actual costs.
Moreover, the Commissioner contends that there were conflicts of interest on the board of Blue Cross itself, which resulted in Blue Cross not being able to negotiate the best contract possible with the hospitals. Consequently, the Commissioner contends that taking all *729these things into account the rate base of Blue Cross could be significantly lower and the resulting cost savings and increased efficiencies in the operation itself would negate a need for a present rate increase.
On August 28, 1972 another proposed rate increase was filed with the Commissioner by Blue Cross with proposed rates higher than the previously proposed rates filed April 4, 1972. The hearing on the April 4, 1972 rate increase was set for September 13, 1972, and at the time of the hearing the Commissioner had neither approved nor disapproved the August 28, 1972 rate increase and limited the hearing to the April 4, 1972 rate increase, which was objected to by Blue Cross. The ruling of the Commissioner confining the hearing to the April 4, 1972 rate increase request, which was approved by the Circuit Court, was proper under the circumstances of this case.
The parties to- this proceeding apparently cannot agree upon the issues involved. Considering the contentions of both parties, a simplified statement of the issues to be considered in the determination of this case are as follows: (1) Are the proposed rates submitted to the Commissioner for approval excessive? (2) Does the Commissioner have the authority to inquire beyond the mere mathematical accuracy of the figures and to inquire into underlying factors upon which the schedule of rates is based?
The brief of Blue Cross and the amicus curiae brief assert that one of the issues is whether the Commissioner has the authority to control hospital charges for services rendered to Blue Cross subscribers. This is not an issue in this case. Not only does the Commissioner not have such authority, he admits that he does not have such authority. However, he does have the authority, and, the duty, to protect the subscribers of Blue Cross, and to ascertain that hospital charges paid by Blue Cross under its contracts with the participating hospitals have a reasonable relationship to the hospitals’ actual costs.
*730The pertinent part of the statute pertaining to the proposed rate increase involved in this proceeding, Code, 33-24-6(c), as amended, reads as follows:
No rates to be charged subscribers shall be used or established by any such corporation unless and until the same have been filed with the commissioner and approved by him. The procedure for such filing and approval shall be the same as that prescribed in subsection (b) of this section for the approval of forms. The commissioner shall approve all such rates which are not excessive, inadequate or unfairly discriminatory.
Under the provisions of this statute the Commissioner has the duty to investigate the rates to be charged to the subscribers of Blue Cross after such rates have been filed with him, and approve them if such rates are not excessive, inadequate or unfairly discriminatory. In approving or disapproving such rates the Commissioner has the authority, and the responsibility, to look behind the figures submitted in the application for a rate increase and to determine the adequacy and reasonableness of the hospitals’ charges to be paid by Blue Cross on behalf of its subscribers. The Commissioner also has the authority and responsibility to see that the Blue Cross Plan is operated properly and efficiently. Thaler v. Stern, 44 Misc.2d 278, 253 N.Y.S.2d 622 (1964); New Hampshire-Vermont Physician Service v. Durkin, _ N.H. _, 313 A.2d 416 (1973). This authority to investigate and inquire beyond the mere mathematical accuracy of the figures applies to an application for a rate increase.
The Commissioner used the report prepared by the Blue Cross Association styled “Total Plan Review” at the hearing to show the weaknesses and criticism of the Blue Cross operation, but the Commissioner did not introduce into evidence an independent examination of Blue Cross to ascertain such matters as required by Code, 33-24-4, as amended, and Code, 33-2-9, as amended, nor had the Commissioner promulgated rules and regulations to guide Blue Cross as provided in Code, 33-24-1, *731as amended. Moreover, the contracts between Blue Cross and the participating hospitals, of which the Commissioner complains, had been previously approved by the Commissioner and he impliedly approved the contracts, every year when he renewed the license for Blue Cross, as required by Code 33-24-5, as amended.
The Blue Cross Association report relied on by the Commissioner in the disposition of the rate hearing contains the following statements with regard to the Blue Cross rates:
During the past three years, the Plan’s reserves, in terms of ratio to claims and operating expenses, have steadily decreased. We attribute this to spiralling hospital costs and inadequate rate adjustments. * * * Moreover, the increase in the cost of these services has greatly outpaced the increase in Blue Cross rates. * * * In general, the current rate structure is not unfairly discriminatory, nor are the proposed rates. However, current rates are inadequate and continued losses can be anticipated until substantial rate increases are effected. * * * We have reviewed the methodology used and the calculations made by the Plan in determining the revised Blue Cross subscriber rates proposed * * *. Also we reviewed the statistical data underlying the calculations. In our opinion, the underlying data are substantially accurate and the methods used were sound.
Although the foregoing quote referred to the June, 1971 filing for a rate increase, which was denied by the Commissioner, it is clear from the evidence introduced by the Commissioner that there was an immediate need for a rate increase because of spiralling hospital costs and inadequate rate adjustments.
The disapproval by the Commissioner of hospital administrators on the Board of Trustees of Blue Cross because of alleged conflicts of interest is not justification for the disapproval of the proposed rate increase. New Hampshire-Vermont Physician Service v. Commissioner, Dept. of Banking and Insurance, _ Vt. _, *732326 A.2d 163 (1974). The by-laws of the national association of Blue Cross require that at least one-third of the directors of the local plans be hospital administrators. In any event, the hospital administrators did not participate as members of the Board of Trustees of Blue Cross in the negotiations of the contracts between the hospitals and Blue Cross.
The reported figures showing the ratio of hospital charges to hospital costs as 129% should be properly checked and if there is no explanation or justification therefor, and the hospitals in question refuse to modify their contracts with Blue Cross to provide for a reasonable relationship of their charges to their actual costs, the Commissioner should disapprove the contracts with the hospitals and order Blue Cross to terminate the contracts in order to protect the best interests of the public. Code, 33-3-9, as amended.
Apparently, the rates charged the subscribers of the Charleston Blue Cross Plan have been excessive in the past due in part to the advent of Medicare in 1966 and proper controls were not applied by the Commissioner. This is indicated by the fact that Blue Cross has not had a rate increase since 1965 and by virtue of inflation since that time resulting in large increases in operating costs, Blue Cross would have been rendered insolvent. The Commissioner should have controlled this matter by proper investigation and conducted hearings for such purpose authorized by Code, 33-2-13, as amended.
If Blue Cross at any time does not comply with the directions, orders and recommendations of the Commissioner after proper investigations, the Commissioner can revoke, refuse to renew, suspend the license of Blue Cross, or in lieu thereof, subject it to a penalty, all of which is authorized by Code, 33-24-6(d), as amended.
There is no question that Blue Cross can be made to conform to the law providing for the operation of such nonprofit corporations. They are given favored consideration under the law and are exempt from the payment *733of all taxes, and should be required to charge such rates to the subscribers of the plan that bear a reasonable relationship to the efficient cost of operation in order to adequately protect those members of the public who subscribe for the services offered by Blue Cross. Code, 33-24-1, as amended.
A hearing can be held on the operations of Blue Cross at any time by the Commissioner if warranted by his examination required by Code, 33-24-4, as amended, and if the evidence adduced at the hearing shows that rates are excessive by inquiry into all pertinent matters relative to the rates charged the subscribers by Blue Cross, such rates can be ordered to be reduced. New Hampshire-Vermont Physician Service v. Durkin, supra.
Although the Commissioner can require Blue Cross to negotiate contracts with the participating hospitals in order to insure that the amounts paid by the hospitals have a reasonable relationship to the hospitals’ actual cost of operation, consideration should be given to necessary operation expenses of such hospitals. The participating hospitals’ charges should allow for the cost of improvements, repairs and bad debts by patients who are unable to pay, or do not pay, for the services rendered by the hospitals. On the other hand, the Commissioner cannot approve a rate increase for expensive, unnecessary medical services, or unnecessary expansion of medical facilities.
In summary, the uncontradicted evidence at the hearing before the Commissioner was that the Charleston Blue Cross Plan was an average plan, its costs of administration were lower than other plans, if the proposed rate increase was not approved it would have become insolvent by the middle of 1973, its reserves were decreasing rapidly under the old rate structure, and the investment program of Blue Cross was of a conservative nature and yielded an adequate return on investments. It is also clear that any inefficiencies in the operations of Blue Cross are not so significant as to obviate the necessity of an immediate rate increase. The evidence in *734this case clearly shows that the proposed rate increase filed by Blue Cross on April 4, 1972 was not excessive. The evidence introduced on behalf of the Commissioner in the Blue Cross Association report stated that the old Blue Cross rates were inadequate, and the contention of the Commissioner that the proposed rates are excessive is not supported by the evidence introduced in this case. The Commissioner, under the provisions of Code, 33-24-6(d), as amended, disapproved the schedule of fees to be paid the hospitals as being actuarily unsound. Even if this finding is correct, there was insufficient evidence introduced at the hearing to show that the schedule of fees was excessive.
There were several minor issues raised by the parties in the trial court, all of which were properly disposed of by the trial court and it is not necessary to discuss them in the disposition of this case.
The judgment of the Circuit Court of Kanawha County is therefore reversed as to its holding that the Commissioner could not inquire beyond the mere mathematical accuracy of the figures submitted by the rate applicant in ruling upon a rate increase filing, but is affirmed in holding that the proposed rate increase filed by Blue Cross is not excessive and should be approved by the Commissioner.
Reversed in part; affirmed in part.
