OPINION

SCOTLAND, P. J.

Under California's Medi-Cal program, a health care provider who furnishes medical assistance to the poor may seek reimbursement from the government for certain expenses, including the cost of employee health care benefits. If the provider is self-insured for such employee benefits, they are allowable costs only if the self-insurance program meets specific requirements.

Oroville Hospital (Oroville) appeals from the trial court's order denying its petition for writ of mandate, seeking to compel the California Department of Health Services (DHS) to reimburse Oroville for money it expended for employee health care.

In the published portions of this opinion, we reject Oroville's contention that the trial court and DHS improperly construed and applied pertinent guidelines found in the Provider Reimbursement Manual. As we will explain, the money that Oroville spent for its employee health care was not an allowable cost because Oroville's self-insurance program did not comply with requirements of the regulatory scheme, in that Oroville did not maintain the fund with an independent fiduciary. Consequently, Oroville was entitled only to partial reimbursement for such costs as "deductibles" under the scheme.

In the unpublished parts of this opinion, we reject Oroville's other claims of error. Accordingly, we shall affirm the judgment.

FACTS

Medicaid is a program through which the federal government provides financial assistance to qualified participating states for furnishing medical assistance to the poor. ( 42 U.S.C. § 1396 et seq.; Children's Hospital Medical Center v. Bonta (2002) 97 Cal.App.4th 740, 747 [ 118 Cal.Rptr.2d 629].) California participates in Medicaid through the Medi-Cal program. (Welf. Inst. Code, § 14000 et seq.; Children's Hospital Medical Center v. Bonta, supra, 97 Cal.App.4th at p. 747.) DHS administers the Medi-Cal program pursuant to the Medi-Cal Act and DHS's regulations. (Welf. Inst. Code, § 14000 et seq.; Cal. Code Regs., tit. 22, § 50000 et seq.)

Oroville provides services to Medi-Cal beneficiaries and is reimbursed for its allowable costs, including indirect costs such as certain employee health benefit payments. (42 C.F.R. § 413.9(c)(3) (2006).) Allowable costs are determined in accordance with Medicare standards and principles of reimbursement as set forth in the Code of Federal Regulations and in HIM-15. (Cal. Code Regs., tit. 22, § 51536, subd. (b)(4).) HIM-15, which is issued by the United States Department of Health and Human Services, became HCFA Pub. 15-1. It is now Centers for Medicare Medicaid Services Publication 15-1 and is known as the Provider Reimbursement Manual (PRM). ( Shalala v. Guernsey Memorial Hospital (1995) 514 U.S. 87, 90 [ 131 L.Ed.2d 106, 113, 115 S.Ct. 1232]; Mercy Home Health v. Leavitt (3d Cir. 2006) 436 F.3d 370, 373.)

The PRM provides that commercial health care insurance is an allowable cost, as are contributions to a self-insurance fund if the self-insurance program meets specific requirements. (PRM §§ 2162, subd. A, 2162.4, 2162.7; further section references are to the PRM unless otherwise specified.) The PRM also allows reimbursement for a combination of purchased insurance and self-insurance. (§ 2162, subd. A.)

Section 2162.4 states in relevant part: "You may believe it appropriate to self insure some of the risk independently or as part of a group or pool and purchase insurance for the remainder of the risk. Where you decide to fund all or some of the risk covered through self-insurance, payments into a fiduciary fund are allowable costs if you or the pool sets up a program which meets the conditions specified in § 2162.7. . . ."

Oroville provided health benefits to its employees through a combination of commercial insurance and a reserve fund, which it refers to as self-insurance. On a monthly basis, it deposited money into its reserve fund, based on the total health care claim expenses from the prior year and on the number of employees. Oroville used money from the fund to pay health claims for services provided to its employees outside of its own facility. To supplement this program, Oroville purchased a commercial insurance policy for a specific "stop loss" limit of $100,000 and an annual aggregate limit of $3.8 million. In other words, the policy paid medical expenses exceeding $100,000 for an individual employee and expenses exceeding $3.8 million for all employees during the entire year.

In its Medi-Cal cost report submitted to DHS, Oroville claimed $3,486,311 in health care costs for employees, including $1,870,088 paid to outside providers for services rendered.

DHS audited the report and determined that Oroville's reserve fund did not meet the self-insurance requirements of section 2162.7, which meant that Oroville was not entitled to reimbursement for the full amount claimed. Instead, DHS treated the amounts paid as insurance deductibles pursuant to section 2162.5 (which limits the reimbursable amount) and allowed reimbursement of only $893,496 for services from outside providers.

Oroville filed a request for a formal administrative hearing, asserting the costs were for reimbursable self-insurance, and DHS erred in determining the health care payments were deductibles.

Following a hearing, the administrative law judge (ALJ) found that Oroville's reserve fund did not meet the requirements of section 2162.7 for a self-insurance program because the fund was maintained by Oroville, rather than an independent fiduciary, and annual certified statements prepared by an independent actuary, insurance company, or broker were not filed with an intermediary. The ALJ concluded the health care payments were deductibles within the meaning of section 2162.5. Thus, the ALJ sustained DHS's audit adjustment, but did so "with some reluctance" because Oroville's costs were not excessive and the reimbursement amount allowed by DHS was inadequate (in fact, it appeared that the cost for Oroville's method of insuring its employees was lower than the cost of commercial health care insurance or of a self-insurance program that meets the requirements of section 2162.7).

The ALJ's proposed decision was adopted as DHS's final decision.

Oroville filed a petition for writ of mandate in the superior court, challenging DHS's decision that the costs were deductibles. The court found that Oroville's "self-insurance" did not fit the requirements of the PRM for self-insurance, and that the health care expenses more closely resembled the payment of deductibles within the meaning of section 2162.5. Accordingly, it denied the petition for writ of mandate.

DISCUSSION I

Oroville contends that DHS misinterpreted PRM section 2162.7 in disallowing reimbursement for money expended on outside provider services pursuant to Oroville's self-insurance plan.

Section 2162.7 states in pertinent part: "A. Definition of Self-Insurance. — Self-insurance is a means whereby a provider(s), whether proprietary or nonproprietary, undertakes the risk to protect itself against anticipated liabilities by providing funds in an amount equivalent to liquidate those liabilities. [¶] If a provider enters into an agreement with an unrelated party that does not provide for the shifting of risk to the unrelated party, such an agreement shall be considered self-insurance. For example, any agreement designed to provide administrative services only shall be considered self-insurance and must meet the requirements specified below. If administrative services agreements do not meet these requirements, any amounts funded as part of the agreement will not be allowed. Payments from the fund, however, will be treated on a claim-paid basis as specified in § 2162.3." (Italics added.)

The various requirements for a self-insurance plan are set forth in subdivisions B through E of section 2162.7. Pursuant to subdivision B, the provider must "establish a fund with a recognized independent fiduciary such as a bank, a trust company, or a private benefit administrator." In addition, "[t]he provider . . . and fiduciary must enter into a written agreement which includes all of the following elements": (1) the parties' legal responsibilities; (2) that the fiduciary has legal title to the fund and has responsibility for its administration and control; (3) that money will be withdrawn only for health care costs; (4) that upon termination from the Medicare program, the provider must obtain a determination of the adequacy of the fund balance; (5) that the fiduciary must prepare a financial statement annually; and (6) that income earned by the fund becomes part of the fund. (§ 2162.7, subd. B.)

Oroville does not dispute the determination by DHS, the ALJ, and the superior court that Oroville's self-insurance plan did not comply with the requirements of section 2162.7 because Oroville did not maintain a fund with an independent fiduciary. Nevertheless, Oroville argues that it is entitled to reimbursement pursuant to the "claim-paid" language of section 2162.7 italicized above. Oroville misinterprets the language in question.

Subdivision B of section 2162.7 mandates that to qualify as a self-insurance plan, the provider (here, Oroville) must establish a fund with a recognized independent fiduciary and must enter into a written agreement including specific requirements concerning the administration of the fund. Subdivision A states in pertinent part: "If administrative services agreements do not meet these requirements, any amounts funded as part of the agreement will not be allowed. Payments from the fund, however, will be treated on a claim-paid basis as specified in § 2162.3." (Italics added.) Curiously, section 2162.3 says nothing about any payments "from" a self-insurance fund; it simply says payments "into" such a fund are allowable costs, but only if the fund meets the conditions of section 2162.7.

It thus appears that section 2162.7's reference to payments treated on a "claim-paid" basis simply means that if the requisite written agreement with an independent fiduciary is somehow deficient, amounts contributed to the fund maintained by the fiduciary will not be allowable costs, but payments from the fund for employee health care costs may be reimbursed on a claim-paid basis. ( Queen's Medical Center v. Blue Cross and Blue Shield Assoc., HCFA Decision (Dec. 21, 1990) PRRB-Dec. No. 91-D2, p. 3 [Medicaid Medicare Guide (CCH) ¶ 38,959] (hereafter Queen's Medical) ["if the administrative service agreement does not meet the requirements of Section 2162.7, any amounts funded as part of the agreement will not be allowed, but payment from the fund will be treated on a `claims-paid' basis"].)

While section 2162.7 specifies that payments from a self-insured fund for employee health care costs may be reimbursed on a claim-paid basis, nothing in the language of the section permits the provider to avoid the section's requirement that for such reimbursement to be obtained, the fund must be established with a recognized independent fiduciary. Both the ALJ and the trial court found that Oroville maintained its own reserve fund rather than establish a fund with a fiduciary. Oroville has not challenged those findings. Therefore, the "claim-paid" language does not apply because this case does not concern a situation where payments are made from a fund maintained by an independent fiduciary with a deficient administrative ser-vices agreement that fails to meet the requirements of section 2162.7.

Relying on Queen's Medical and Indian River Memorial Hospital v. Blue Cross and Blue Shield Assoc. (Mar. 15, 1989) PRRB-Dec. No. 89-D31 [Medicaid Medicare Guide (CCH) ¶ 37,810] (hereafter Indian River), Oroville argues that section 2162.7 has been interpreted as allowing reimbursement on a claim-paid basis under circumstances similar to this case. Oroville's reliance on the cited cases is misplaced.

Observing that section 2162.7 requires a fund must be established with an independent fiduciary, Indian River found the Florida patient compensation fund had "essentially the same obligations and powers required for the fiduciary of a self-insurance fund." ( Indian River, supra, PRRB-Dec. No. 89-D31 at pp. 10-11.) In other words, the provider made contributions to a fund maintained by the equivalent of an independent fiduciary. Here, in contrast, Oroville's fund is not managed by an entity with essentially the same obligations and powers required of a fiduciary; Oroville maintains its own reserve fund.

Queen's Medical found that the patient compensation fund (PCF), an independent state fund in which the provider had been enrolled, dissolved one month prior to the end of the provider's cost year. Under the circumstances, "the most equitable treatment [was] to allow reimbursement for claims paid that would have been covered by the PCF." ( Queen's Medical, supra, PRRB-Dec. No. 91-D2 at pp. 2, 5.) Oroville points to no similar equitable considerations in the present case.

Simply stated, Oroville has not established that DHS misapplied section 2162.7.

II

DHS allowed Oroville a partial reimbursement for amounts paid for health care services, finding that the payments were deductibles within the meaning of section 2162.5.

Oroville argues DHS's definition of a deductible is unreasonable and should not be applied.

Section 2162.5 states: "Where you, at your option, are willing to commit your resources toward meeting first dollar losses through a deductible (as defined below), losses relating to the deductible are allowable costs in the year paid without funding if the aggregate deductible is no more than the greater of 10 percent of your (or, if appropriate, a chain organization's) net worth — fund balances as defined for Medicare cost reporting purposes — at the beginning of the insurance period or $100,000 per provider. The same rule applies where you coinsure with an insurance carrier. This requirement is deemed a reasonable test as to whether you are acting prudently in this regard. So long as you stay within the above limitations, you can be assumed to be exercising sound judgment in deciding to meet first dollar losses or coinsurance payments out of available resources. This requirement also permits you to pay reasonable losses without incurring costs to fund such payments. If your deductible or coinsurance exceeds the above requirements and the provider does not make payments into a fiduciary fund as required by § 2162.7, any losses paid by the provider in excess of the greater of 10 percent of the provider's or, if applicable, a chain organization's net worth, or $100,000 per provider, are not allowable, [¶] For purposes of this section, a `deductible' refers to the amount of first dollar losses not covered by a purchased insurance policy, a funded self-insurance program, or a combination of both." (Italics added.)

Because Oroville's reserve fund was not a qualifying self-insurance plan and thus the "claim-paid" language of section 2162.7 did not apply, and because Oroville's policy required it to pay the first $100,000 of health care costs for an individual employee or the first $3.8 million of costs for all employees, the payments in question were first-dollar losses not covered by a purchased insurance policy or a self-insurance program. Hence, it appears DHS did not err in determining that the payments were deductibles under the definition provided in section 2162.5.

Oroville argues that treating payments for outside health care service as deductibles, which limits the amount of reimbursement rather than reimbursing for the entire amount paid, is inconsistent with the treatment of payments for health care services provided by Oroville, which are treated as fringe benefits and are wholly reimbursable.

(5) Assuming the correctness of the factual predicates underlying Oroville's argument, the disparity in the method of treatment of the different costs does not permit us to ignore the relevant sections of the PRM simply because we may not understand or agree with the underlying policy decisions. (Cf. Superior Court v. County of Mendocino (1996) 13 Cal.4th 45, 52-53 [ 51 Cal.Rptr.2d 837, 913 P.2d 1046] [judiciary may not undertake to evaluate the wisdom of the policies embodied in legislation; the choice among competing policy considerations in enacting laws is a legislative function].) If Oroville believes deductibles should not be limited as set forth in section 2162.5, or payments for health care costs from a reserve fund maintained by the provider should be treated as self-insurance, Oroville's remedy is to ask the branch of government responsible for the rules to change them.

III, IV

Contending the PRM is simply an interpretive guideline, which does not have the force and effect of law ( Shalala v. Guernsey Mem. Hosp., supra, 514 U.S. at p. 99 [ 131 L.Ed.2d at p. 119]), Oroville argues that we need not follow the PRM when doing so would violate statutory or regulatory authority. ( St. John's Hickey Mem. Hosp., Inc. v. Califano (7th Cir. 1979) 599 F.2d 803, 812-814.) But Oroville does not refer us to any statutory or regulatory authority that the pertinent provisions of the PRM necessarily contravene. Oroville merely points out that "reasonable costs" are statutorily defined as "the necessary costs of efficiently delivering covered services to individuals covered by the insurance programs established by this subchapter" ( 42 U.S.C. §§ 1395x (v)(1)(A)), and that regulations are to be designed to assure "the costs with respect to individuals not so covered will not be borne by such insurance programs. . . ." ( Ibid.) According to Oroville, the PRM sections at issue here aid in defining what are considered reasonable costs, but the interpretation given them by DHS is not reasonable since it will "deny reimbursement for `necessary costs of efficiently delivering services' to Medi-Cal beneficiaries, placing a disincentive on Oroville to provide services in the most `efficient' way, in tension with federal law. This denial would effectively shift $976,592 of self-insurance costs to non-Medi-Cal payors such as Medicare and private third-party payors, violating Title 42 U.S.C. section 1395x (v)." Oroville asserts that "[i]f the PRM fails to capture effectiveness and reasonableness, it does not fulfill the goals of interpreting the controlling statutes" and is contrary to law. Oroville did not raise this theory in the trial court or at the administrative hearing. In fact, according to the trial court, the parties were "in agreement that the relevant legal standards to be applied to this matter are set forth in the Medi-Cal Provider Reimbursement Manual (`PRM')." Because Oroville did not challenge the validity of the PRM guidelines, DHS was not given an opportunity to present evidence regarding the policy underlying the PRM's limitation on the reimbursement of deductibles, why the PRM requires a fund with an independent fiduciary to establish a self-insurance program, how these policies generally result in costs savings, and other related issues. Also, Oroville did not present any evidence establishing that the limitation on reimbursement of its employee health care costs necessarily would result in those costs being shifted impermissibly in violation of 42 U.S.C. §§ 1395x (v)(1)(A)). Since Oroville did not preserve this contention for appeal, we need not address it further. ( Kuperman v. San Diego County Assessment Appeals Bd. No. 1 (2006) 137 Cal.App.4th 918, 930; City of Oakland v. Public Employees' Retirement System (2002) 95 Cal.App.4th 29, 52.)

IV

Finally, Oroville contends DHS failed to proceed in the manner required by law because it relied on an interpretive guideline that was not promulgated in accordance with the Administrative Procedure Act (APA). Section 51536(b)(4) of title 22 of the California Code of Regulations states: "Allowable cost means the hospital's allowable Medi-Cal cost permitted by applicable Medicare standards and principles of reimbursement, 42 CFR, Part 405 and HIM-15." As noted previously, HIM-15 is the PRM. Thus, the cited regulation incorporates by reference the PRM, which is the guideline that DHS used to disallow a portion of the requested reimbursement. Oroville observes that regulation 51536 was adopted in 1980, but the PRM has been modified many times thereafter. In its view, the new version of the PRM may not be applied without first being formally adopted in a new regulation subjected to the review process under the APA. Again, Oroville did not raise this theory in the trial court or at the administrative hearing. In fact, Oroville agreed the PRM was the relevant legal standard. In any event, Oroville provides no authority supporting the proposition that where a state agency, entrusted with implementing a federal program, adopts an administrative regulation in accordance with the APA, and the regulation incorporates by reference governing federal guidelines, then the regulation must be subjected to a new APA review process whenever the incorporated federal guidelines are amended or modified by the federal government. Rather, Oroville relies on an inapposite case, which intimates that where a state agency incorporates by reference its own manual in a regulation and thereafter changes the manual, the agency may have to submit a new regulation to the APA review process to incorporate the changes to the manual in the regulation. ( Kings Rehabilitation Center, Inc. v. Premo (1999) 69 Cal.App.4th 215, 217-220.) "A party may not ordinarily raise a new theory on appeal. [Citation.] We are not obliged to consider an issue not properly briefed on appeal [citations], nor factual issues not litigated in the trial court [citations], nor issues not timely raised in an administrative proceeding [citations]." ( City of Oakland v. Public Employees' Retirement System, supra, 95 Cal.App.4th at p. 52.)
