This appeal involves the small employer group health coverage act,1 which establishes requirements for insurance carriers that offer health insurance benefit plans to small employers in Michigan. We address the narrow issue of whether § 3711(2) of the act, MCL 500.3711(2), prevents a carrier from requiring a small employer to pay a minimum percentage of its employees’ health insurance premiums.2
*70Both the Court of Appeals and the Commissioner of the Office of Financial and Insurance Services (OFIS)3 concluded that minimum employer contribution provisions are inconsistent with the act. They reasoned that an employer’s failure to pay a minimum percentage of its employees’ premiums is not among the reasons in MCL 500.3711(2) that a carrier may refuse to renew an insurance plan. We disagree with this rationale and reverse their decisions. We hold that merely because the Legislature did not include noncompliance with a minimum employer contribution provision among the reasons for nonrenewal does not render the provision unreasonable or inconsistent with § 3711(2).
BACKGROUND4
Priority Health is a nonprofit corporation that the state of Michigan has licensed as a health maintenance organization. It offers health benefit plans to many employers in Michigan, including small-employer groups covered by the act. Its policies require minimum employer contributions.5 Employers contracting with it *71must agree to contribute a certain portion of the insurance premium. Priority Health asserts that a minimum employer contribution requirement combats “adverse selection” — the tendency of healthy people to decline health insurance because of its cost — by encouraging a greater number of healthy employees to participate in the plan, thereby allowing carriers to charge lower premiums.6
In April 2006, Priority Health requested a declaratory ruling from OFIS.7 It asked whether a health maintenance organization may require small employers to contribute a specific minimum in payment of the premiums if that minimum is reasonable and is applied uniformly. Priority Health asserted that a minimum employer contribution requirement is designed to address adverse selection. It argued that, by ensuring that a portion of the cost is borne by the employer, the financial burden on the employees is lessened. This makes it more likely that healthy employees will participate in the plan.
The commissioner8 issued a declaratory ruling in which she concluded that the mandated employer contribution in Priority Health’s policies is unreasonable and inconsistent with the act. She reasoned that an employer’s failure to pay a portion of the premiums is not one of the conditions in MCL 500.3711(2) that permits a carrier to refuse to renew coverage.
Priority Health appealed the ruling in the circuit court, which affirmed it. Applying the standard of *72review in MCL 24.306(1), the circuit court concluded that the commissioner’s interpretation of the act was not arbitrary or capricious. As a result, it concluded that the ruling should be affirmed.9
Priority Health sought leave to appeal in the Court of Appeals, arguing that the OFIS ruling and the circuit court’s decision conflicted with the language of the act. It further argued that its minimum employer premium contribution requirement advances the act’s purposes because it encourages employee participation and protects against adverse selection. The Court of Appeals denied Priority Health’s application for leave to appeal, with Judge SMOLENSKI indicating that he would grant the application.10 However, this Court remanded the case to the Court of Appeals as on leave granted.11
On remand, the Court of Appeals affirmed the decision of OFIS in a published opinion per curiam.12 Most significant to our analysis, it agreed with the commissioner’s legal conclusion. Consequently, it held that the act does not permit carriers to impose a minimum employer contribution requirement on small employers as a condition for issuing a health benefit plan.13
This Court granted leave to appeal to determine (1) whether, as part of a plan, an insurer or licensed health *73maintenance organization can require an employer to pay a specific percentage of the premium charged for each employee and (2) whether MCL 500.3711(2) limits the provisions that can be included in such policies.14
STANDARD OF REVIEW
We review OFIS declaratory rulings in the same manner as any agency final decision or order issued in a contested case.15 Here, OFIS was requested to interpret a statute. Statutory interpretation is a question of law, which we review de novo.16 However, an agency’s interpretation of a statute regarding matters it is charged with regulating is entitled to respectful consideration and should not be overruled without cogent reasons.17
KEY PROVISIONS OF THE ACT
The act regulates small employer group health coverage in Michigan. The Legislature adopted it in 2003 in an effort to resolve problems specific to the small-employer market. The act requires every insurance carrier wishing to provide health care benefits to small employers in Michigan to offer all of its small-employer health plans to all small employers.18 At MCL *74500.3707(1), it also requires a small-employer carrier to issue any health benefit plan it markets to any small employer that: (1) applies for the plan, (2) agrees to pay the required premium, and (3) agrees to satisfy other reasonable provisions of the health benefit plan not inconsistent with the act.
The act provides that the carriers of small-employer benefit plans must renew the policies they issue to small employers, except under very limited circumstances. At MCL 500.3711, it states:
(1) Except as provided in this section, a small employer carrier that offers health coverage in the small employer group market in connection with a health benefit plan shall renew or continue in force that plan at the option of the small employer or sole proprietor.
(2) Guaranteed renewal under subsection (1) is not required in cases of: fraud or intentional misrepresentation of the small employer or, for coverage of an insured individual, fraud or misrepresentation by the insured individual or the individual’s representative; lack of payment; noncompliance with minimum participation requirements; if the small employer carrier no longer offers that particular type of coverage in the market; or if the sole proprietor or small employer moves outside the geographic area.
Hence, MCL 500.3707 and MCL 500.3711 read together require every carrier of small-employer benefit plans to make all its plans available to all small employers. With six exceptions, the carrier must renew the coverage at the employer’s option.
ANALYSIS
The act does not expressly permit carriers of small-employer benefit plans to mandate a minimum em*75ployer contribution in their policies. However, it does permit them to include provisions that are “reasonable” and “not inconsistent” with the act.19 As a consequence, minimum employer contribution requirements are permissible so long as they are “reasonable” and “not inconsistent” with the act.
In her ruling, the commissioner relied on her interpretation of the guaranteed-renewal provisions in MCL 500.3711. They require small-employer carriers to guarantee renewal of their health plans at the option of the employer, except in six expressly identified circumstances. Failure to comply with a minimum employer contribution requirement is not one of those circumstances. Hence, the commissioner concluded that a carrier must renew coverage without regard to the level of an employer’s contribution to the total cost of the plan.
She reasoned that it would be inconsistent to “allow a minimum contribution requirement at the time coverage is issued, yet mandate renewal without regard to the employer’s share.”20 And she concluded that Priority Health’s minimum contribution requirement was unreasonable because it was inconsistent with the guaranteed-renewal provisions of MCL 500.3711.21
Likewise, the Court of Appeals based its decision on the guaranteed-renewal provisions in MCL 500.3711. Following a rationale similar to that of the commissioner, the Court found it “unreasonable and inconsistent to require [minimum employer] contributions as a prerequisite for initial coverage when renewal could not be denied on the basis of a failure to pay those contributions.”22
*76Both the commissioner and the Court of Appeals improperly relied on the guaranteed-renewal provisions of MCL 500.3711 to conclude that minimum employer contribution requirements are impermissible in small-employer policies. Our reading of chapter 37 of the Insurance Code, in which the act is found, persuades us that minimum employer contribution requirements are not inconsistent with MCL 500.3711. The guaranteed-renewal provisions do not limit the initial coverage that can be included in a policy. Rather, they mandate renewal of the initial policy that was offered to the employer once it is in effect. Any provisions included in the initial policy are part of the policy that must be renewed at the employer’s option according to MCL 500.3711(1).
If a minimum employer contribution requirement is included as a provision of the initial policy, it is part of the policy being offered for renewal. If the employer determines that it cannot or does not wish to make such a contribution, it is free to decline to renew the policy. This differs from a situation where the carrier refuses to renew the policy for a reason not among the permissible reasons enumerated in MCL 500.3711(2). Nothing in chapter 37 prevents an employer from declining to renew the policy.
Moreover, under the Court of Appeals’ rationale, any proposed health benefit plan provision which MCL 500.3711(2) does not expressly permit would be unreasonable and inconsistent with chapter 37. This means that a carrier could not require an employer to agree to an arbitration clause, merger or integration clause, or other common provision that it did not write into the initial policy. According to the Court of Appeals’ reasoning, small-employer carriers would not be able to include any provisions in their plans that the act does not expressly permit.
*77Yet chapter 37 does not require a proposed policy provision to be expressly authorized by chapter 37 before a small-employer carrier can include it in a policy. Such an interpretation would effectively read out of the act the language of MCL 500.3707(1) that permits a carrier to include “other reasonable provisions of the health benefit plan not inconsistent with this chapter.” If the only provisions a carrier could include in a policy were those expressly enumerated in the exceptions to guaranteed renewal, it could never include other reasonable provisions. A critical tenet of statutory construction is to give meaning to every portion of a statute, and interpretation of a provision that renders any part of the statute surplus-age is to be avoided.23
Assuredly, the guaranteed-renewal provisions could be said to conflict with, and thus preclude, the inclusion of certain provisions in a health benefit plan for initial coverage. MCL 500.3711(2) lists only six reasons why a carrier can terminate or refuse to renew a health plan that has already been issued. A provision that attempted to broaden those exceptions would conflict with MCL 500.3711 and would be impermissible in a policy for initial coverage.
For example, a termination-at-will provision cannot be reconciled with the guaranteed-renewal provisions and therefore would be prohibited. But MCL 500.3711 does not preclude a carrier from including a reasonable provision in a policy for initial coverage that does not conflict with the enumerated reasons for nonrenewal.
CONCLUSION
We give respectful consideration to the commissioner’s interpretation of chapter 37. But MCL 500.3711(2) *78does not support her conclusion that a minimum employer premium contribution provision is inconsistent with the act. An insurance carrier is not prohibited from including a provision in plans offered to small employers simply because it is not listed in MCL 500.3711(2) among the reasons for nonrenewal. Rather, unless a provision directly conflicts with the enumerated reasons, it may be included in a plan so long as it is reasonable and not inconsistent with chapter 37.24 We do not reach the question of whether Priority Health’s minimum employer premium contribution provision is unreasonable or inconsistent with the act for reasons not presented in this case. We reverse the judgment of the Court of Appeals, vacate the OFIS declaratory ruling, and remand this case to OFIS for reconsideration of plaintiffs motion for declaratory judgment in light of this opinion.
Cavanagh, Markman, Hathaway, Mary Beth Kelly, and ZahrA, JJ., concurred with Marilyn Kelly, J.MCL 500.3701 et seq.
We decline to address the broader issue of whether such required contributions are unreasonable or inconsistent with the act for any other *70reason. The commissioner and the lower courts based their rulings on the determination that minimum employer contribution requirements conflict with MCL 500.3711(2). We reverse that determination and therefore need not address arguments on which no definitive ruling was issued below.
OFIS has since been renamed the Office of Financial and Insurance Regulation.
Because this dispute involves an OFIS declaratory ruling, no administrative agency hearing was conducted, and the record consists of those facts specifically identified by Priority Health in its request for a declaratory ruling. Mich Admin Code, R 500.1043(2).
A minimum employer contribution provision requires an employer to contribute a portion of an employee’s premium. Minimum contribution requirements set a ceiling on the health insurance expenses an employer may pass on to its employees. This ceiling is often expressed as a percentage of the premium.
