In 1988 Cоngress enacted legislation to ameliorate the financial hardship suffered by aging couples faced with the high cost of nursing home care. These consolidated appeals examine the extent to which the Iowa Department of Human Services (DHS), in implementing that legislation, may use the cost of an annuity as the yardstick by which to measure the noninsti-tutionalized spouse’s monthly maintenance needs allowance. On judicial review, the district court found DHS violated its rule-making authority in doing so. We reverse and remand for an order enforcing the agency’s decision.
I. Background facts and proceedings. Resolution of this controversy turns primarily on an analysis of agency authority under Iowa Code chapter 17A (1991), the Administrative Procedure Act. But to put that analysis in a factual сontext, we begin with a brief legislative history of pertinent provisions of the Medicare Catastrophic Coverage Act, 42 U.S.C. § 1396r-5 (1990) (hereafter “MCCA”).
As already noted, Congress passed the MCCA in part to aid citizens whose spouses reside in nursing homes or other medical institutions and receive Medicaid benefits. Under prior law, nearly all of a couple’s assets had to be deplеted before either one could satisfy Medicaid eligibility requirements, leaving the spouse who remained in the community in a financially precarious position. H.R.Rep. No. 105(II), 100th Cong., 2d Sess. 65-68 (1988), reprinted in 1988 U.S.C.C.A.N. 803, 888-92 (hereafter “House Report”). The MCCA was de *28 signed to avoid impoverishing the “community spouse.” Id. at 892.
Congress was also mindful that — as part of a welfare program — Medicaid eligibility rules should not “facilitate the transfer of accumulated wealth from nursing home patients to their nondependent children.” Id. at 896. Thus the MCCA requires that an institutionalized spouse’s income and resources cannot exceed published supplemental security income (SSI) limits. Id. at 888-92. For example, when these proceedings arose, an institutionalized spouse owning more than $2000 was required to apply that resource toward medical bills and nursing home еxpense. 42 U.S.C. § 1382(a); 20 C.F.R. 416.1205(c). Only when that resource dipped below the SSI limit would the person become eligible for Medicaid. House Report at 888, 892. Certain assets, such as a house, car, personal effects and household goods, are not counted towards the SSI limit. Id. at 892.
Under this regulatory scheme, all of a couples’ “countable” resources are regarded as available to the institutionalized spouse, except an amount called the “community spouse resource allowance,” or CSRA. 42 U.S.C. § 1396r-5(c)(2). The CSRA is one-half of the couple’s total resources, or $60,000, whichever is less. 42 U.S.C. § 1396r-5(f)(2); 441 Iowa Admin.Code § 75.5(3)(d). The CSRA is not considered available to the institutionalized spouse and thus is not counted toward the SSI limit. 42 U.S.C. § 1396r-5(c)(2), (4).
The institutionalized spouse is also permittеd to divert a portion of monthly income to the community spouse. This deduction from the institutionalized spouse’s monthly income is known as the “community spouse monthly income allowance.” 42 U.S.C. § 1396r-5(d)(1)(B). The allowance depends on a figure called the “minimum monthly maintenance needs allowance,” which (at the time of these proceedings) was a maximum of $1500. 42 U.S.C. § 1396r-5(d)(3)(C). In other words, the institutionalized spouse can divert however much the community spouse needs to bring that spouse’s monthly income to the $1500 needs allowance. 42 U.S.C. § 1396r-5(d)(1)(B), (d)(2).
If diversion of the institutionalized spouse’s income to the community spouse does not reach the $1500 monthly maintenance allowance, the agency can increase the CSRA upon application by either spouse. 42 U.S.C. § 1396r-5(e)(2)(C). Thе controversy before us centers on this provision.
The Fords and Glodens are both couples with one spouse in a nursing home (the “institutionalized spouse”) and the other remaining in the couple’s home (the “community spouse”). In the Ford case the institutionalized spouse filed an application for Medicaid with DHS, and in Gloden the community spouse requested determination оf the Medicaid “community spouse resource allowance” without an application for Medicaid. See 42 U.S.C. § 1396r-5(e)(1). In both cases, the initial community spouse resource allowance left significant resources that had to be spent before Medicaid eligibility for the institutionalized spouse could be established. In the Ford case, the initial community spouse resource allowance was one-half ($32,177.26) of the couple’s total countable resources of $64,-354.53, leaving the other half to be counted for Medicaid eligibility for the institutionalized spouse. In the Gloden case, the initial community spouse resource allowance was the maximum, then $60,000, from the couple’s total countable resources of $136,-847.07. This left $76,847.07 to be counted towаrd Medicaid eligibility for the institutionalized spouse.
Both couples requested an administrative hearing to increase the community spouse resource allowance and thus decrease the amount counted for Medicaid eligibility for the institutionalized spouse. In each case, an administrative law judge increased the CSRA to an amount sufficient, if invested in bank accounts and certificates of deposit, to generate enough additional monthly income to reach $1500. In the Fords’ case, the community spouse had $1165.92 monthly income; he was thus entitled to sufficient resources to generate an additional $334.08 per month. The administrative law *29 judge determined that, at the prevailing interest rates, the sum of $51,728.25 was necessary to generate that amount and thus bring the community spouse’s monthly income up to $1500. The AU thus set the CSRA for the Fords at $51,728.25.
In the Glodens’ case, the community spouse had a monthly income of only $308, requiring an additional $1192 to bring her up to $1500. However, the sum of all the couple’s resources would not generate that amount, so the administrative law judge set the CSRA at $136,847.07, leaving no resources available to the institutionalized spouse.
On administrative review, the DHS director decided that, instead of looking at the investment of resources necessary to generate sufficient interest income (the “interest-only” method), the agency should look at the resources necessary to purchase a single-premium life annuity that would furnish monthly payments to the community spouse in an amount sufficient to bring the spousе’s income up to $1500. It was determined that in the Ford case an annuity would cost less than the initial CSRA, so the initial CSRA of $32,177.26 was affirmed. In the Gloden case an annuity paying $1192 per month could be purchased for a single-premium payment of $112,986, an amount substantially less than the $136,847 set aside under the interest-only method. DHS amended the Gloden CSRA accordingly. In neither case were the parties required to purchase an annuity; their applications to increase the CSRA were simply resolved on the basis that their needs could be met through the liquidation of assets and purchase of an annuity.
The Fords and Glodens petitioned the district court to challenge these decisions. Their petitions for judicial review rested on two legal arguments. First, they argued that the interest-only method is mandated under federal and state law. Second, they argued that even if the annuity method were allowable, it could only be applied following rule-making proceedings and it was unlawful for the agency to adopt such a policy in a contested case proceeding.
The district court agreed with the petitioners and reversed the agency, ruling that the аnnuity method could not be applied until it had been formally adopted as an agency rule. The court did not decide the legality of the annuity method. The court ordered the agency to compute the CSRA in each case using the interest-only method. It is from this ruling that DHS appeals.
II.
Scope of review.
In judicial review proceedings, the district court functions in an appellate capаcity to correct errors of law.
Anderson v. Iowa Dep’t of Human Servs.,
III. Issues on appeal. On appeal, DHS reasserts its position that it was unnecessary to formally adopt a rule permitting the annuity method of valuing the CSRA prior to applying such a method in these cases. It also contends that the annuity method violates neither state nor federal Medicaid regulations. We shall consider the arguments in turn.
A. Rule-making vs. case-by-case adjudication. This case illustrates the tension in administrative law between formalized rule-making and case-by-case adjudication of statutory standards. On the one hand, Iowa Code section 17A.3(2) operates to invalidate any agency rule or “other written statement of law or policy” that has not first been subjected to public inspection and indexing as required by section 17A.3(1)(c) and (d). Yet the administrative procedure act itself exempts from the definition of “rule” any “determination, decision, or order in a contested ease.” Iowa Code § 17A.2(7).
This court has previously held, in the case of a proposed rule, that section 17A.3(2) does not come into play unless the agency аpplies the rule as a matter of law, rather than merely applying the policy considerations underlying the rule that are relevant to the factual situation presented.
Young Plumbing & Heating Co. v. Iowa Natural Resources Council,
At the same time,
Young
recognized that the choice of whether to develop policy by rule, contested case, or both, lies “[within] the informed discretion of the administrative agency.”

(quoting
S.E.C. v. Chenery Corp.,
Against this backdrop we consider the parties’ competing claims. The federal Medicaid provision at issue requires DHS to allow the community spouse “an amount adequate to provide such a minimum monthly maintenancе needs allowance.” 42 U.S.C. § 1396r-5(e)(2)(C). DHS argues that its director merely decided to use an annuity calculation as the method for determining what the appropriate amount should be. The method had not been adopted as a departmental policy when these cases arose, nor was it contained in any rule or proposed rule. 1 The petitioners, on the оther hand, persuaded the district court that the director’s decision reflected a policy of general application and future effect which was invalid without formal adoption as a rule.
The record does not support the district court’s conclusion. Although this appeal demonstrates that the methodology chosen by the director was applied in twо cases, that is far from proof that the annuity method had been adopted as an ironclad rule without reference to individual circumstances making it more or less appropriate. To the contrary, the record reveals that the director compared the CSRA computed under the interest-only method with the computation yielded by the annuity method. The director concluded the latter was more in keeping with the overall purpose of these welfare regulations: to insure the community spouse’s ability to live with independence and dignity, while minimizing the transfer of accumulated wealth to non-dependent children.
As noted by the Supreme Court in
Chenery,
an agency may not have had sufficient experience with an administrative problem “to warrant rigidifying its tentative judgment intо a hard and fast rule.”

Legality of annuity method under state and federal Medicaid regulations.
Although the district court reversed the agency on procedural grounds and did not reach the merits of the controversy, the question of the legality of the annuity

method was fully briefed by the parties. Because the case reaches us solely on this question of law, the parties urge us to address it without further remand to the agency. In the interest of judicial economy, we shall do so.
See Mary v. Iowa Dep’t of Transp.,
It is a fundamental tenet of administrative law that when a litigant challenges an agency’s interpretation of statutes governing its work, the agency’s expertise in such matters is entitled to deference.
Washington v. Bowen,
The relevant statute at issue provides:
If either such spouse establishes that the community spouse resource allowance (in relation to the amount of income generated by such an allowance) is inadequate to raise the community spouse’s income to the minimum monthly maintenance needs allowance, there shall be substituted, for thе community spouse resource allowance under subsection (f)(2) of this section, an amount adequate to provide such a minimum monthly maintenance needs allowance.
42 U.S.C. § 1396r-5(e)(2)(C). The dispute centers on the regulation’s use of the word “income.” The gist of the petitioners’ argument is that community spouses should be able to meet their maintenance needs from interest only, without touching the principal portion of the resource allowance. DHS argues that this interpretation would facilitate the transfer of the couple’s accumulated wealth to their children or other heirs, contrary to legislative intent. We quite agree.
As already noted elsewhere in this opinion, Medicaid is a program for poor people “whose income and resources are insufficient to meet the costs of necessary medical services.” 42 U.S.C. § 1396. The companion spousal provisions were enacted to insure that the spouse who remains in the community will have “a sufficient — but not excessive — amount of income and resources available [while the spouse] is in a nursing home at Medicaid expense.” House Report at 888 (emphasis added). To that end, Congress designed a program to benefit welfare recipients, not persons seeking to benefit their heirs at the expense of other taxpayers.
Petitioners argue that an annuity payment cannot be considered “income” because the payment reflects a return on principal as well as income. DHS concedеs that, in the context of determining Medicaid or SSI eligibility, the argument has validity. The argument follows from rules granting an exception for changes in the form of a resource. Under SSI rules, receipts from the sale or exchange of a resource are not counted as income but merely as resources that have changed their form. 20 C.F.R. § 416.1103(c). The exception rests on the principle that the same asset should not be counted twice in determining eligibility for SSI or Medicaid.
As DHS points out, however, here neither the cost of the proposed annuity nor the payments are being counted to determine eligibility. Rather, the cost of an annuity is being used to determine the amount of resources, otherwise available to the institutionalized spouse, that will be attributed to the community spouse and thus not factored into the determination of the institutionalized spouse’s Medicaid eligibility. For this purpose, DHS argues, return of principal is indistinguishable from interest earnings and should be considered income. See 42 U.S.C. § 1382a(a)(2)(B) (for SSI eligibility purposes, unearned income *32 includes any payment received as annuity, pension, or retirement benefit); 20 C.F.R. § 416.1121(a) (same).
We find nothing in the regulations to overcome the reasonableness of DHS’s interpretation. Moreover, the contrary position taken by the petitioners seems to us unreasonable and not in harmony with the regulatory scheme. If we were to rule, as a matter of law, that the income-only method must prevail, gross inequities would result between couples with adequate pension and social security income, and those with little income but substantial accumulated resources. A community spouse with pension income equal to the maintenance needs allowance would be limited to a maximum resource allowance of $60,000. But, under petitioners' analysis, a community spouse without monthly income could, at present rates, accumulаte over one-quarter million dollars without reaching the CSRA limit. Such a result would clearly conflict with any notion that this is a welfare program for poor persons. It would also unfairly penalize couples that have accumulated rights to pensions or social security payments, rather than liquid assets, over their working life.
In effect, the annuity method requires the conversion of liquid assets into a private pension. Pension benefits may be used to meet the community spouse’s monthly maintenance allowance. See 42 U.S.C. § 1396r-5(d)(2)(B). We believe that the department’s demand that such a conversion be made in these cases is not unreasonable, given the assets available to the parties and the fact that the rules grant substantial exemption for homestеad, personal effects, and an automobile.
In summary, we conclude that the annuity method chosen by DHS implements a reasonable interpretation of the MCCA. This interpretation is entitled to our deference. Therefore we reverse the judgment of the district court and remand for an order enforcing the department’s ruling.
REVERSED AND REMANDED.
Notes
. During the pendency of this appeal, the agency formally adopted the annuity method by rule. See 441 Iowa Admin.Code § 75.5(3)(f)(2) (1991).
