    PUBLISHED OPINION
    v.
    WASHINGTON STATE DEPARTMENT OF
    HEALTH; ROCKWOOD HEALTH SYSTEM
    d/b/a VALLEY HOSPITAL,
    Respondents.
    BJORGEN, C.J. — Providence Physician Services Co. (PPSC) appeals the superior court
    decision affirming the final order by the Department of Health (Department) ruling that PPSC
    did not qualify for an exemption from the Certificate of Need (CN) Program for its proposed
    ambulatory surgical facility. WAC 246-310-010(5) provides the exemption at issue, which
    permits an ambulatory surgical facility “in the offices of private physicians . . . whether for
    individual or group practice” without CN approval, as long as “the privilege of using the facility
    is not extended to physicians . . . outside the individual or group practice” (the ASF exemption).
    PPSC, a physician group entirely owned by Providence Health and Services –
    Washington (Providence), requested a determination as to whether the ASF exemption applied to
    it and its proposed facility. After an adjudicative process, the Department ultimately concluded
    that PPSC did not qualify for the ASF exemption. The superior court affirmed the Department.
    PPSC now appeals to this court, arguing that (1) the Department erred because the ASF
    exemption does not require a physician group (a) to be separately and independently owned and
    (b) to possess its own facility space; and (2) the Department engaged in improper rule making
    without abiding by the required formal rule making procedures.
    No. 47885-4-II
    We hold that the Department did not err in finding that Providence’s ownership of PPSC
    disqualified it from the ASF exemption, although it did err to the extent it ruled that PPSC must
    own the facility space to qualify for the exemption. Furthermore, we hold that the Department
    did not engage in rule making with its interpretation of the ASF exemption. Accordingly, we
    affirm.
    FACTS
    Providence is a large nonprofit health care conglomerate that operates healthcare
    facilities in and outside of Washington. Through one of its subsidiaries, Providence is the sole
    shareholder and owner of PPSC. PPSC is a separately created for-profit corporation that
    employs 27 surgeons.
    Recently, Providence built the Providence Sacred Heart Medical Center (Medical Center)
    in Spokane, a 134,000 square feet medical park with two separate buildings connected by an
    adjoining bridge. The Medical Center provides a wide range of health care services, including
    ambulatory surgical facilities. An ambulatory surgical facility is “any free-standing entity . . .
    that operates primarily for the purpose of performing surgical procedures to treat patients not
    requiring hospitalization.” WAC 246-310-010(5). PPSC proposed to lease from Providence a
    portion of the Medical Center’s building that contained the ambulatory surgical center and to
    limit that facility’s privileges to PPSC surgeons.
    PPSC submitted this proposal to the Department’s CN Program for a determination as to
    whether it would be subject to CN approval. WAC 246-310-050. The CN Program initially
    decided that PPSC was not required to obtain a CN for the new facility because the proposed
    facility did not qualify as an ambulatory surgical facility under the ASF exemption. That
    exemption reads:
    2
    No. 47885-4-II
    Th[e] term [ambulatory surgical facility] does not include a facility in the offices
    of private physicians or dentists, whether for individual or group practice, if the
    privilege of using the facility is not extended to physicians or dentists outside the
    individual or group practice.
    WAC 246-310-010(5). Rockwood Health System objected to the CN Program’s determination
    and requested an adjudicative proceeding to determine the applicability of the ASF exemption.
    WAC 246-310-610. The parties agreed that this issue could be fully resolved through a
    summary judgment proceeding, since there were no genuine issues of material fact and the legal
    issue was whether the ASF exemption applied to PPSC’s proposed facility.
    The Department’s hearing officer presiding over the initial adjudicative proceeding ruled
    that PPSC’s proposed interpretation of the ASF exemption was too broad and rendered the term
    “private” meaningless. Administrative Record (AR) at 228. In addition, the hearing officer
    noted that a statutory provision should be construed in accordance with the CN’s purpose to
    control health care costs by ensuring better utilization of existing medical services and to limit
    the expansion of new medical services. The hearing officer construed the ASF exemption
    narrowly because the legislature had not created any specific exemption for ambulatory surgery
    centers. The hearing officer concluded that if PPSC surgeons owned the proposed ambulatory
    surgery center, it would qualify for the ASF exemption. However, because Providence owned
    PPSC’s ambulatory surgery center, the hearing officer held the ASF exemption inapplicable.
    PPSC sought review of the Department’s initial order before a departmental review
    officer. WAC 246-10-608, -701(1). The review officer concluded that PPSC did not qualify for
    the ASF exemption on two grounds: first, because PPSC’s proposed ambulatory surgical center
    would be located in the Medical Center, which is a mixed use ambulatory health care facility,
    and second, because PPSC surgeons are employees of Providence, and even if they were not
    3
    No. 47885-4-II
    employees, PPSC is entirely owned by Providence. Thus, both the hearing officer and the
    review officer relied on Providence’s ownership as a reason for denying the exemption.
    In reaching his decision, the review officer relied on the definition of “private practice” in
    Merriam Webster’s Online Dictionary, which is the “practice of a profession (as medicine)
    independently and not as an employee.” AR at 310; http://www.merriam-webster.com. The
    review officer also noted that PPSC was not a private practice because “PPSC itself
    characterized its practice as neither a solo nor group practice.” AR at 310 n.7. Thus, the review
    officer concluded that to allow PPSC’s proposed facility to qualify for the ASF exemption would
    “undermine the statutory requirement that [ambulatory surgical facilities] be subject to CN
    review.” AR at 310. Along with the above conclusions, the review officer also incorporated the
    hearing officer’s initial order into the Department’s final order.
    The superior court affirmed the Department’s final order, and PPSC appeals.
    ANALYSIS
    I. STANDARD OF REVIEW
    In reviewing an administrative action, we sit in the same position as the superior court
    and apply the Administrative Procedure Act (APA), chapter 34.05 RCW, standards directly to
    the agency’s administrative record. Shaw v. Dep’t of Ret. Sys., 
    193 Wash. App. 122
    , 128, 
    371 P.3d 106
    (2016). Thus, we do not review the superior court’s decision; rather, we examine the
    agency’s final order, except to the extent that the review officer adopts the hearing officer’s
    initial order. See Darkenwald v. Emp’t Sec. Dep’t, 
    183 Wash. 2d 237
    , 244, 
    350 P.3d 647
    (2015);
    RCW 34.05.570(3). The Department’s decision in a CN case is presumed correct, and the
    challenger has the burden to overcome that presumption. Overlake Hosp. Ass’n v. Dep’t of
    Health, 
    170 Wash. 2d 43
    , 49-50, 
    239 P.3d 1095
    (2010).
    4
    No. 47885-4-II
    Because questions of law are the only issues in this appeal, we review the Department’s
    actions—whether characterized as adjudicative or “rule making”— under the error of law
    standard. See Verizon Nw., Inc. v. Wash. Emp’t Sec. Dep’t, 
    164 Wash. 2d 909
    , 915, 
    194 P.3d 255
    (2008) (citing RCW 34.05.570(3)(d)). This standard allows us to substitute our view of the law
    for that of the Department’s. 
    Id. If, however,
    the particular law was promulgated by the
    Department or is within the scope of its expertise, we accord substantial weight to the
    Department’s interpretation. 
    Id. II. INTERPRETATION
    OF THE ASF EXEMPTION
    PPSC argues that the Department erred in interpreting the ASF exemption because the
    exemption does not require a physician group to be separately and independently owned and to
    possess its own facility space. As explained below, we find that the Department did not err in its
    interpretation to the extent it determined that Providence’s ownership of PPSC disqualified it
    from the ASF exemption, but did err to the extent it determined that PPSC must own the facility
    space to qualify for the exemption.
    1.     Legal Principles
    The legislature has authorized the Department, through an appointed secretary, to
    administer the CN Program. RCW 70.38.105(1), .025(4); RCW 43.70.030. “The CN program
    was created as part of Washington’s health planning strategy to ‘promote, maintain, and assure
    the health of all citizens in the state, provide accessible health services, health manpower, health
    facilities, and other resources while controlling increases in costs, and recognize prevention as a
    high priority in health programs.’” Overlake Hosp. 
    Ass’n, 170 Wash. 2d at 50
    (quoting RCW
    70.38.015(1)).
    5
    No. 47885-4-II
    In order for an entity to construct, develop, or establish a new “health care facility,” it
    must obtain a CN from the Department. RCW 70.38.105(4)(a). Health care facilities include
    ambulatory surgical facilities. RCW 70.38.025(6); WAC 246-310-010(26). While the
    legislature did not define “ambulatory surgical facility,” the Department defined the term as:
    any free-standing entity, including an ambulatory surgery center that operates
    primarily for the purpose of performing surgical procedures to treat patients not
    requiring hospitalization. This term does not include a facility in the offices of
    private physicians or dentists, whether for individual or group practice, if the
    privilege of using the facility is not extended to physicians or dentists outside the
    individual or group practice.
    WAC 246-310-010(5)1 (emphasis added.) The italicized part of the Department’s definition
    created an exception for a certain type of ambulatory surgical facility that would otherwise
    require CN approval. The interpretation of this exemption is the subject of this appeal.
    The rules of statutory construction apply to agency created rules and regulations.
    Odyssey Healthcare Operating B, LP v. Dep’t of Health, 
    145 Wash. App. 131
    , 141, 
    185 P.3d 652
    (2008). The primary goal of statutory construction is to determine and give effect to the
    legislature’s intent. SEIU Healthcare 775NW v. Dep’t of Soc. & Health Servs., 
    193 Wash. App. 377
    , 398, 
    377 P.3d 214
    , review denied, 
    186 Wash. 2d 1016
    (2016). To decipher legislative intent,
    we examine the plain language of the statute, the context of the statute in which the provision is
    found, and related statutes. 
    Id. “When the
    statute at issue or a related statute includes an
    applicable statement of purpose, we interpret statutory language in a manner consistent with that
    stated purpose.” 
    Id. 1 In
    Washington State Hosp. Association v. Washington State Department of Health, 
    183 Wash. 2d 590
    , 
    353 P.3d 1285
    (2015), our Supreme Court held that WAC 246–310–010(54) was invalid
    because the Department exceeded its authority in promulgating that provision.
    6
    No. 47885-4-II
    “To discern the plain meaning of undefined statutory language, we give words their usual
    and ordinary meaning and interpret them in the context of the statute in which they appear.” 
    Id. at 399.
    “‘We may use a dictionary to discern the plain meaning of an undefined statutory term.’”
    
    Id. (quoting Nissen
    v. Pierce County, 
    183 Wash. 2d 863
    , 881, 
    357 P.3d 45
    (2015)). Generally,
    “statutory exceptions are construed narrowly in order to give effect to the legislative intent
    underlying the general provisions.” Foster v. Dep’t of Ecology, 
    184 Wash. 2d 465
    , 473, 
    362 P.3d 959
    (2015).
    2.     “Private Physicians” in a “Group Practice”
    Using these legal principles, we must decide whether the Department’s final
    interpretation of the meaning of “private physicians” in a “group practice” was an error of law.
    We hold that the Department did not err.
    PPSC’s main argument is that it is a “group practice” of “private physicians” within the
    ASF exemption’s plain language and that the ASF exemption does not contemplate a distinction
    between physician groups based on ownership. The Department and Rockwood contend that the
    Department’s decision to rely on the dictionary definition of “private practice” to find PPSC not
    qualified for the ASF exemption was sound and was in accordance with the statutory scheme and
    the CN Program’s purpose.
    As noted previously, the review officer relied on the Merriam Webster’s Online
    Dictionary definition of “private practice,” which is the “practice of a profession (as medicine)
    independently and not as an employee.” MERRIAM 
    WEBSTER’S, supra
    . PPSC is correct that the
    words “private” and “practice” are not written immediately next to each other in the language of
    the ASF exemption. Instead, the exemption covers “a facility in the offices of private physicians
    or dentists, whether for individual or group practice, [as long as] the privilege of using the
    7
    No. 47885-4-II
    facility is not extended to physicians or dentists outside the . . . practice.” WAC 246-310-010(5).
    Thus, the “private physicians” who qualify for the exemption must also be organized for
    “individual or group practice.” Since “private physicians” in a “practice” reasonably implies a
    private practice, the Department properly relied on the definition of “private practice” in its
    interpretation of the ASF exemption.
    PPSC counters that, under this definition of “private practice,” associates at law firms
    would not be considered engaged in “private practice” because they do not have an ownership
    interest in their firms. This argument, however, confuses the dictionary definitions of “private
    practice” with its more colloquial meaning. Under a general dictionary definition (not the
    medical definition noted above), the term includes not only professionals who do not work for
    the government, but also those that are “not controlled or paid for by . . . a larger company (such
    as a hospital).” MERRIAM 
    WEBSTER’S, supra
    . Therefore, the lawyer who worked either for the
    public or for a large legal company or law firm would not be considered engaged in “private
    practice” under these dictionary definitions. Although PPSC tries to appeal to our colloquial
    understanding of “private practice” in law firms, the dictionary defines “private practice”
    uniformly across the professions as those not controlled by a larger company. A group of
    physicians, therefore, who are controlled or paid for by a hospital would not fall under the
    definition of “private practice.”
    Providence, through one of its subsidiaries, is the sole shareholder and owner of PPSC.
    Thus, the review officer correctly determined that PPSC surgeons are not engaged in private
    practice under these definitions and therefore do not fall under the terms of the ASF exemption.
    Even if we were hesitant in following the Department’s use of dictionary definitions in
    interpreting the ASF exemption, the Department’s interpretation is demanded by the purpose of
    8
    No. 47885-4-II
    the CN Program. We will uphold an agency’s interpretation “if it reflects a plausible
    construction of the language of the statute and is not contrary to the legislative intent.” Seatoma
    Convalescent Ctr. v. Dep’t of Soc. & Health Servs., 
    82 Wash. App. 495
    , 518, 
    919 P.2d 602
    (1996).
    A central purpose of the CN Program is to control health care costs by ensuring better utilization
    of existing medical services and limiting the expansion of new medical services. See RCW
    70.38.015.
    These policies would be eviscerated under PPSC’s interpretation. Simply put, under
    PPSC’s theory, a hospital that sought to establish an ambulatory surgical facility could
    circumvent the CN requirement merely by creating another entity, which in effect would still be
    under the ownership and direction of the hospital. By repeating this scenario, hospitals would be
    able to balloon the amount of ambulatory surgical facilities in Washington and undermine the
    cost controlling measures of the CN Program through the guise of a pseudo-subsidiary that is
    otherwise under the authority of the hospital. We agree with the Department that to entertain
    such an interpretation of the rule would emasculate the CN’s underlying policies by exalting
    “form over substance.” Safeco Ins. Co. v. Meyering, 
    102 Wash. 2d 385
    , 394, 
    687 P.2d 195
    (1984).
    Both parties discuss in great detail prior decisions from the Department’s CN Program,
    each finding cases that support their respective position. PPSC cites three decisions where the
    Department’s administrators concluded that the ASF exemption applied to hospital-owned
    physician groups that limited the use of their ambulatory surgical facilities to only those
    physicians. The Department and Rockwood cite two prior decisions where the Department
    concluded the opposite. As Rockwood points out though, these initial analyst decisions have no
    binding effect in ascertaining whether the Department erred in its interpretation of the ASF
    exemption. See DaVita, Inc. v. Dep’t of Health, 
    137 Wash. App. 174
    , 181-84, 
    151 P.3d 1095
    9
    No. 47885-4-II
    (2007). Furthermore, even if the initial analyst decisions were entitled to any deference, they
    were inconsistent at best.
    The Department and Rockwood also bring to our attention the only prior decision that
    was subject to the Department’s adjudicative process: the Multicare case. In that case,
    Multicare sought to qualify for the ASF exemption for its “corporate division” the Multicare
    Medical Associates (MMA). MMA was subject to Multicare’s corporate control, including the
    managing of MMA’s billing, collection, and setting of fees. Multicare would hire the physicians
    through MMA. The Department in Multicare ruled that
    [t]he common meaning of “private” within the CN regulatory context does not
    include this type of corporate employed physician. Within this context, private
    physicians or private practice physicians are those who practice privately, as
    physicians separate from a large non-physician health care entity. The “group
    practice” exemption to the CN regulation was intended to assist the private practice
    physician for the treatment of their own patients in their own offices. An
    interpretation of [the ASF exemption] that would permit large, non-physician
    health care entities to utilize the exemption, would create an enormous exemption
    for hospitals or other non-physician corporations that would defeat the very purpose
    of the CN law of ambulatory surgical centers.
    AR 66 (Paragraph 2.12).
    Although we ultimately vacated the Department’s decision based on its lack of
    jurisdiction, see Multicare Health System v. Department of Health, noted at 
    147 Wash. App. 1024
    (2008), that decision did not affect the Department’s ruling immediately above on the meaning
    of the ASF exemption. That ruling is consistent with the Department’s interpretation of the
    exemption in the current case and further buttresses our conclusion that PPSC’s proposal does
    not fall under the ASF exemption.
    PPSC contends that Multicare is distinguishable because Multicare itself sought to rely
    upon the ASF exemption rather than a separately created entity, such as PPSC. We are hard
    pressed, however, to find a difference of significance to these issues between a corporate
    10
    No. 47885-4-II
    subdivision such as MMA, and a separate legal entity such as PPSC, entirely owned by the
    hospital. As already stated, we will not permit an interpretation of the ASF exemption that
    promotes “form over substance.” Safeco Ins. 
    Co., 102 Wash. 2d at 394
    .
    Finally, PPSC argues that Amisub of South Carolina, Inc. v. South Carolina Department
    of Health and Environmental Control, 
    403 S.C. 576
    , 
    743 S.E.2d 786
    (2013), is persuasive
    authority from South Carolina on the interpretative issue at hand. In Amisub, a nonprofit
    healthcare system owned a physician group, “CPN,” and sought to build a new urgent care
    center. 
    Id. at 578-79.
    South Carolina law provided that “health care facilities” were subject to
    CN review, which included hospitals, but not urgent care centers. 
    Id. at 587.
    Further, South
    Carolina law specifically exempted “‘the offices of a licensed private practitioner whether for
    individual or group practice’” from CN requirements. 
    Id. at 589
    (quoting S. C. CODE ANN. § 44-
    7-170(A)(2)).
    Although the Amisub court decided the case on jurisdictional grounds, in dicta it stated
    that an urgent care center did not qualify as a “hospital” as to become a “health care facility”
    subject to CN review. 
    Id. at 597
    n.16. Further, the court noted that the urgent care center would
    not have been subject to CN review because the private practitioner exemption does not
    contemplate “treat[ing] physicians’ offices owned by hospitals differently.” 
    Id. To do
    so “would
    constitute an improper judicial restriction on a legislative provision, and it would effectively
    eviscerate the private business model, a result that we do not believe was ever intended by the
    General Assembly.” 
    Id. Because South
    Carolina statutes did not list urgent care centers as a type of facility
    requiring CN review, 
    id. at 587,
    this decision is of little moment to the appeal before us. In
    addition, the Amisub court’s concern that imposing CN review under its facts would “eviscerate
    11
    No. 47885-4-II
    the private business model” in South Carolina, 
    id. at 597
    n.16, does not raise any concern about
    Washington’s CN Program. As already noted, the CN Program’s goal in Washington is to
    provide accessible and efficient use of health services, while controlling costs, 
    Overlake, 170 Wash. 2d at 50
    (citing RCW 70.38.015(1)), and we interpret the ASF exemption in accordance with
    this purpose. SEIU 
    Healthcare, 193 Wash. App. at 398
    .
    Whether we consult the definitions of relevant terms, prior decisions, or, most
    importantly, the purposes of the CN program, PPSC’s proposal should not be deemed a facility
    in the offices of private physicians for individual or group practice under the plain language of
    the exemption. Thus, the Department correctly determined that PPSC’s proposal did not fall
    within the ASF exemption.
    3.     Space-Ownership Requirement
    PPSC next argues that the Department erred in reading a “space-ownership” requirement
    into the ASF exemption. Br. of Appellant at 30-32. Rockwood responds that this is a “red
    herring” and not germane. Brief of Rockwood at 16-17. We agree that the Department arguably
    interpreted the ASF exemption to require PPSC to own its space within the Medical Center. To
    that extent, we agree with PPSC that the Department erred in this reading of the ASF exemption.
    The ASF exemption provides that an ambulatory surgical facility “does not include a
    facility in the offices of private physicians.” WAC 246-310-010(5) (emphasis added). The plain
    meanings of “facility” and “offices” do not contemplate a requirement that private physicians
    must own the ambulatory surgical facility in which they work. Furthermore, the purposes of the
    CN Program would not be furthered merely by requiring a truly private group practice of
    physicians to own the space in which they operate.
    12
    No. 47885-4-II
    Thus, to the extent the Department imposed a space-ownership requirement to qualify for
    the ASF exemption, it erred.
    III. RULE MAKING AUTHORITY
    PPSC next argues that the Department’s interpretation of the ASF exemption was a
    “rule” subject to the formal rule making procedures outlined in the APA. The Department
    argues that PPSC waived this issue, and even if not waived, the Department and Rockwood
    contend that the Department’s interpretation did not create a new “rule.” Although we disagree
    that PPSC waived this challenge, we do agree with the respondents that the Department’s
    interpretation of the ASF exemption was not a rule subject to the formal rule making procedures.
    1.     Waiver
    The Department contends that we should not consider this argument because PPSC failed
    to raise it in the adjudicative proceedings and did not preserve the issue for appeal. PPSC argues
    that under this particular factual scenario, where the new interpretation of the ASF exemption
    was the result of the Department’s adjudicative proceedings, it should have been entitled to
    challenge what it believed to be “rule making” for the first time at the superior court.
    We agree with PPSC. Only at the close of the adjudicative proceedings was PPSC faced
    with the action it claims was rule making. In this posture, PPSC did not waive its rule making
    claim by failing to raise it during the adjudicative proceedings.
    2.     Interpretation of Rule
    The APA sets out certain formal requirements that an agency must follow before
    adoption of a new rule. City of Vancouver v. Pub. Emp’t Relations Comm’n, 
    180 Wash. App. 333
    ,
    361-62, 
    325 P.3d 213
    (2014) (citing RCW 34.05.310-.395). If an agency adopts a rule without
    compliance with these required procedures, the rule is invalid. RCW 34.05.570(2)(c). However,
    13

    (alteration in original). In order to qualify as a “rule” under the APA, two elements must be
    satisfied. Budget Rent A

    . First, an agency action must be an “order,
    directive, or regulation of general applicability.” RCW 34.05.010(16)2. Second, as applicable to
    this appeal, the agency action must
    (c) . . . [e]stablish[], alter[], or revoke[] any qualification or requirement relating
    to the enjoyment of benefits or privileges conferred by law; [or]

    Id. In applying
    this definition of “rule” to agency actions, Washington courts have repeatedly
    held that agencies are empowered to interpret a statute or regulation without going through
    formal rule making procedures. Examples include interpretation of the phrases “the total of all
    passenger cars in the fleet,” Budget Rent A 
    Car, 144 Wash. 2d at 893
    , 897-98, and “sale or
    issuance,” Regan v. Department of Licensing, 
    130 Wash. App. 39
    , 55, 
    121 P.3d 731
    (2005), as well
    as the word “reasonable.” McGee Guest Home, Inc. v. Dep’t of Soc. & Health Servs., 96 Wn.

    If, however, an agency adds a new requirement to an already well defined regulation, that
    requirement will be deemed a “rule” subject to the formal rule making procedures. Failor’s
    Pharmacy v. Dep’t of Soc. & Health Servs., 
    125 Wash. 2d 488
    , 
    886 P.2d 147
    (1994). In Failor’s
    Pharmacy, the Department of Social and Health Services (DSHS) had two specifically
    articulated factors for calculating Medicaid reimbursement to pharmacies. 
    Id. at 490-91.
    DSHS
    later decided to use an additional consideration in calculating Medicaid reimbursement that was
    not contemplated within the two original factors. 
    Id. at 491-92.
    The Failor’s Pharmacy court
    held that DSHS’s new consideration was a “rule,” 
    id. at 494,
    that “‘functionally added a third
    requirement to the two requirements set out in the regulations.’” Budget Rent A 
    Car, 144 Wash. 2d at 897
    (quoting McGee Guest 
    Home, 142 Wash. 2d at 323
    ) (characterizing the holding in Failor’s
    Pharmacy in this manner). Thus, while Washington courts have recognized that an
    administrative agency cannot add additional requirements to an already well articulated
    regulation without formal rule making, they have repeatedly concluded that interpretation of
    broadly written existing law is within its adjudicative authority. Budget Rent A 
    Car, 144 Wash. 2d at 897

    PPSC is correct that the Department’s interpretation of the ASF exemption will be
    generally applicable to any hospital-owned physician group that tries to apply for that exemption.
    However, adjudicative proceedings that resolve an issue of interpretation frequently have some
    general effect. That general effect, though, does not necessarily transform that resolution into
    rule making. As long as the Failor’s Pharmacy rule is observed, that effect no more transforms
    15
    No. 47885-4-II
    the Department’s adjudication into rule making than it transforms a court’s ruling upholding the
    action into legislation.
    Unlike Failor’s Pharmacy, the Department in this appeal did not attempt to promulgate
    additional requirements to qualify for the ASF exemption. Rather, it exercised its interpretative
    authority to give meaning to the existing language that established the existing contours of the
    exemption. That interpretation of the ASF exemption is similar to the agency interpretations in
    Budget Rent A Car, Regan, and McGee Guest Home, which were found to not be rule making.
    PPSC argues that the Department engaged in rule making because its interpretation of the
    ASF exemption contradicts its earlier administrative decisions to allow hospital-owned physician
    groups to qualify for the exemption. As we noted above, however, the prior initial
    determinations of the Department were inconsistent at best. In particular, the Multicare decision
    questioned any prior decisions allowing hospital-owned physician groups to qualify for the ASF
    exemption.
    Even assuming that the Department was consistent in its prior decisions to allow hospital-
    owned physician groups to qualify for the exemption, they were made by administrators deciding
    the specific case before them on an ad hoc basis. At oral argument, PPSC cited WAC 246-310-
    050(5) for the proposition that a specific applicability determination relating to a particular party
    binds the Department in a later interpretation of a regulation’s meaning. However, these initial
    decisions by administrators are not binding on the Department generally, but only on the specific
    parties involved. See 
    DaVita, 137 Wash. App. at 181-84
    .
    For these reasons, we hold that the Department did not engage in rule making.

    CONCLUSION
    We hold that the Department did not err in its interpretation that Providence’s ownership
    of PPSC disqualified PPSC’s proposal from the ASF exemption, but did err to the extent it
    determined that PPSC must own the facility space to qualify for the exemption. We also hold
    that the Department’s interpretation of the ASF exemption did not constitute a rule requiring it to
    engage in formal rule making procedures. Accordingly, we affirm.
