with whom MAASSEN, Justice, joins, dissenting.
In my view, the court's interpretation of AS 88.30.028 is incorrect, and traditional methods of statutory construction-looking to the statute's text, legislative history and purpose, longstanding interpretations of administrative regulations, and policy considerations-all require the opposite interpretation. I would hold that AS 88.80.028 does not render a prisoner lacking collateral resources enumerated in subsection (a) personally liable for the costs of medical care obtained from outside providers. Accordingly, I respectfully dissent and do not join the plurality opinion.1
*40Alaska Statute 33.30.028 is divided into two subsections. Subsection (a) states that medical care "provided or made available to a prisoner" is "the responsibility of the prisoner and the [five enumerated third-party collateral sources, such as insurers and government welfare agencies]." Subsection (a)'s assignment of liability is made "subject to (b) of this section." Subsection (b) directs the Department of Corrections (DOC) to "require prisoners who are without resources under (a) of this section" to pay for medical care "provided to them by the department" and also goes on to specify a minimum payment "based on the prisoner's ability to pay."2 This appeal raises the question of whether a prisoner who has received medical care outside of the DOC system but does not have access to one of the enumerated collateral sources listed in subsection (a) is rendered personally liable for the cost of the outside medical services under AS 33.830.028.
In my view, the best reading of this statute is that subsection (a) creates personal Hability for all types of health care-both that provided in-house by DOC staff and contractors and that made available by outside medical providers-when the prisoner has a collateral source enumerated in subsection (a). But when a prisoner has no such collateral source, then subsections (a) and (b), read in conjunction, create personal liability on the part of the prisoner only for health care provided in-house by DOC but not for care rendered by outside health care professionals.
The court today takes a different view. It interprets this statute's "plain" and "natural meaning" as making the prisoner personally liable for all types of medical care, both in-house and outside-full stop-and creating third-party liability for those sources enumerated in subsection (a). The court interprets subsection (b) as having no effect whatsoever on subsection (a)'s assignment of liability, concluding instead that subsection (b) is merely a directive to DOC to charge a minimum payment to prisoners without resources enumerated in subsection (a) for care provided in-house by DOC.3 The court reasons that (1) the statutory language "plain{ly]" 4 compels this "natural reading," 5(2) this interpretation is consistent with the statute's "primary purpose ... to reduce medical costs" 6 and the statute's legislative history indicating "an intent to take advantage of any financial resources to which a prisoner might have access," 7 and (8) DOC's regulations implementing this statute are not inconsistent with this interpretation.8 In my view, the court has essentially redrafted the statute, disregarding its plain text, relevant legislative history, and a contrary interpretation by DOC. In doing so, the court has enacted a new policy that will harm the State's fiscal and public safety interests in supporting the successful reentry of prisoners into the community upon their release from incarceration.
The court's interpretation is foreclosed by the text of the statute. Subsection (a) specifically conditions its assignment of liability on *41subsection (b): "[Thhe liability for payment of the costs of medical ... care provided or made available to a prisoner ... is, subject to (b) of this section, the responsibility of the prisoner and the [enumerated collateral sources]...."9 The definition of "subject to" 10 and the legislature's deliberate choice to include it in this statute 11 show that subsection (a)'s assignment of liability must be read in conjunction with, and is limited by, subsection (b). If the court were correct, and subsection (a) established a flat assignment of personal liability while subsection (b) merely established an unrelated directive for DOC to charge mandatory minimum fees in certain cases regarding in-house care, then the subject-to clause would serve no purpose, and its deletion would not alter the meaning of the statute at all. But "[wle must ... presume 'that the legislature intended every word, sentence, or provision of a statute to have some purpose, force, and effect, and that no words or provisions are superfluous.'" 12 The court today "step(s]l over the line of interpretation and engag[es] in legislation" 13 by reading out subsection (a)'s subject-to clause from the statute.
I would avoid such judicial redrafting of a legislative enactment by interpreting the statute as written: Subsection (b)'s requirement that DOC recoup some of the costs for in-house care "provided" by DOC for those prisoners without sources enumerated in subsection (a) must limit, by means of the subject-to clause, subsection (a)'s assignment of liability. The only interpretation that preserves all the words of the statute would draw on the distinction between subsection (b)'s use of "provided" and subsection (a)'s use of both "provided" and "made available." This distinction, in conjunction with the subject-to clause, would lead to the conclusion that subsection (a) makes a prisoner personally liable for medical costs provided in-house and for medical costs made available outside of DOC where the prisoner has a collateral source enumerated in subsection (a), but that subsection (a) does not make a prisoner personally liable for medical care rendered by outside healthcare professionals where the prisoner lacks an enumerated source from subsection (a). This interpretation respects the legislature's drafting choices, requires no additions to the statute, and makes no subtractions from the statute. Unfortunately, the same cannot be said of the court's interpretation.
The court responds to my argument by asserting that the subject-to clause is not superfluous because subsection (b) directs DOC to collect payment from prisoners under certain conditions.14 This assertion simply ignores the meaning of "subject to" in the statutory phrase "subject to (b) of this seetion." The court would read this text, which plainly limits subsection (a)'s assignment of liability by demanding that it be read in conjunction with a limitation in subsection (b), as merely indicating to the reader: "And subsection (b) also exists, although it has no effect here." The court then claims that "elven if our reading of the statute did render the 'subject to' clause redundant," that redundancy "is closer to the text" than *42my interpretation.15 But my interpretation calls for no addition to, subtraction from, or alteration of the text of the statute. All it requires is acknowledging the meaning of "subject to," reading the two elauses in conjunction, and respecting the means employed by the legislature when it chose the text of AS 33.30.028. My interpretation does not create a "substantial negative implication";16 rather, it follows the explicit statutory directive to read subsection (a) in conjunction with, and as limited by, subsection (b).
The court's interpretation of AS 88.30.028 creates another surplusage problem. Subsection (a) enumerates five collateral sources that are "responsibfle}" for the in-house and outside medical care costs of prisoners. If the court were correct that subsection (a) gives the prisoner responsibility for all costs incurred for all types of medical care, then enumeration of specific collateral sources would be redundant. Even without enumeration, DOC could still invoice those who are already derivatively liable for the prisoner's health care, such as the prisoner's insurer or a public agency providing benefits to the prisoner. The only possible purpose for enumeration of collateral sources in (a) that would not render the enumeration mere sur-plusage would be to limit, in conjunction with subsection (b) and the subject-to clause of subsection (a), prisoner liability for certain types of care where the prisoner lacks an enumerated source.17
The court responds by hypothesizing three purposes for enumerating collateral sources. But none of the court's reasons seem plausible. The court asserts that enumerating sources in subsection (a) "gives notice to potential collateral payers," 18 but it could hardly be news to an insurer that it is liable for medical costs covered by its contract with the insured.19 It could hardly be news to a government agency that it would provide benefits for people who meet the qualifications for benefits.20 And it could hardly be news to parents and guardians that they may be liable for the medical care of their minor children.21'The court also asserts that enumeration "provides prisoners with guidance about their payment and coverage options," 22 but the Alaska Statutes provide rules of law and are generally not thought of as means for providing non-binding financial advice to prisoners. And the court asserts that enumeration "provides the DOC with a list of alternative payers to collect from,23} but DOC could collect from anyone already liable for a prisoner's health care even without enumeration. Under the court's theory, the statute's legal effect would thus not be altered one iota by omitting enumeration, and the court does not resolve this surplus-age problem. Moreover, there is no indication whatsoever in the legislative history that the legislature had any such non-legal reasons for enumerating collateral sources.
*43In sum, the court's opinion effectively deletes statutory text by omitting it from its main conclusion that subsection (a) assigns personal liability for all medical costs to the prisoner. The court's conclusion ignores the subject-to clause from the statute as well as the enumeration of collateral sources. Only by eliminating critical language in the statutory provision can the court read it to create the unconditional assignment of personal liability for all medical care that the court finds in AS 38.80.028 today.
The court's interpretation is also contradicted by the statute's purpose. It is clear from the legislative history of AS 38.80.028 that the legislature intended for this statute to deter frivolous prisoner medical complaints and the overuse of medical services.24 It is also clear that this deterrence rationale outweighed any subsidiary goal of recovering costs.25 (Indeed, almost all of the cost-savings discussion in the legislative history revolved around an entirely different statute that was part of the same bill and would make certain terminally ill prisoners eligible for special medical parole in order to remove from the public the burden of paying for their health care costs.)
That the statute's primary purpose is to deter overuse of medical resources supports the plain-text interpretation that subsection (a) assigns personal liability to the prisoner for all in-house care, but assigns personal liability only for outside care where a prisoner has a collateral source enumerated in (a). Prisoners are free to seek in-house medical services on their own volition, thus making copayment through personal liability a useful deterrent to frivolous medical complaints. But personal liability for a copayment for treatment by outside staff would not serve the goal of deterring frivolous overuse of medical services because prisoners receive outside medical treatment only upon referral from in-house prison staff26 Simply put, with DOC medical staff standing as gatekeepers, there is no frivolous overuse of outside medical resources that would be deterred by personal liability for copayments.27 *44Thus, the statute's purpose is furthered by the text the legislature used to enact it; the court's interpretation of that text today does not further the legislature's goal.
Despite this clear legislative history, the court concludes that "the primary purpose of this statute is to reduce medical costs."28 The court reaches this conclusion by quoting dicta from one of our prior cases interpreting AS 33.80.028 in which we held that the statute applied to former prisoners as well as current prisoners .29 In that case, we stated: "Although the legislative history does not . explicitly address extending liability to former prisoners, preventing the State from collecting from prisoners to the fullest extent possible would contravene the statute's cost-saving purpose."30 Citing only this very general statement of legislative intent from a case addressing a distinct issue, today's court concludes that including a "prisoner's personal wealth among those resources subject to reimbursement is consistent with the statute's primary purpose of reducing the DOC's medical costs." 31
The court is incorrect in its conclusion that the primary purpose of the statute is to reduce DOC's medical costs through cost recovery. The court mistakenly relies on dicta regarding legislative intent in our pri- or decision interpreting AS 33.30.028. In that case, we addressed an issue for which there was no need to go beyond a conclusion that the purpose of the statute, stated at the highest level of generality, was cost savings. But reducing frivolous use of DOC medical services is a measure that saves costs. We had no reason to detail these more specific cost-saving goals, such as deterring over-use of in-house medical services, because examining legislative purpose at a high level of generality sufficed to answer the question presented. Accordingly, we did not purport to give the final word on the purpose of AS 38.80.028. By contrast, this case raises the question of the more specific purpose of the statute; one proffered purpose-raising revenue-favors one interpretation while another proffered purpose-deterrence of frivolous use of medical services-favors a different interpretation. As discussed above, the legislative history clearly indicates that deterrence of frivolous overuse was the primary purpose of AS 83.30.028.
The court today deletes from the statute the subject-to clause and the enumeration of collateral sources in subsection (a), and then reaches its conclusion by relying on an abstract statement of legislative purpose unsupported by the legislative history or the legislative text. Properly used, legislative intent can clarify statutory text, but the intent must be discerned carefully and should never supplant the plain meaning of unambiguous text.
The court relies on a single statement in the legislative history to support its conclusion that the legislature intended for AS 33.830.028(a) to establish personal liability for outside medical care. Its reliance is misplaced. The court quotes a staffer testifying in the House Finance Committee that the legislation was intended to reach "individuals . that will have other coverage or resources," including "the resources of someone that is independently wealthy." 32 The court concludes from these pieces of evidence that "the committee intended that a prisoner's personal wealth be included within the coverage of this statute." 33 The legislative history certainly does suggest that the legislature sought to make prisoners personally liable *45for at least some expenses. For that matter, so does the legislative text of subsection (a). Thus, appeals to legislative history on this point are unnecessary. But this general statement of intent is simply irrelevant in this case. My interpretation of AS 88.30.028 would assign personal liability for at least some medical costs. The more specific question before the court today is whether AS 33.30.028 assigns personal lability in only those cases where a prisoner received in-house care and where the prisoner received outside care and also has enumerated collateral resources, or whether the statute also assigns personal liability in those cases where the prisoner received outside care and lacks enumerated collateral resources. In the end, the court points to absolutely no support for its reconstruction of the abstract purpose animating this statute, nor does it respond to or refute the voluminous contrary legislative history.
The court's interpretation is also inconsistent with the longstanding interpretation of the statute by DOC's own regulations. In 22 Alaska Administrative Code (AAC) 05.121, DOC implemented the authority granted by the legislature in AS 33.30.028. The regulations specify in subsection (b)(1) that "a prisoner is financially responsible for a co-payment for health care services provided to the prisoner by the department through department employees or designated contractors" 34 while subsection (b)(2) specifies that "a prisoner shall arrange for the department to obtain payment or coverage from one or more of the responsible parties set out in AS 38.30.028(a), if the prisoner receives health care services not provided through department employees or designated contractors." 35
These regulations interpret AS 38.30.028 in accord with my interpretation of the statute and contrary to the court's conclusion today. Subsection (b)(1) makes the prisoner personally "financially responsible" for costs incurred in-house, while subsection (b)(2) conspicuously omits any declaration of personal financial responsibility for outside medical care and instead directs the prisoner to "arrange for ... payment ... from one or more of the responsible parties set out in AS 33.30.028(a)." The most natural reading of this language is that the prisoner is not personally financially responsible for outside medical care when he lacks enumerated collateral sources. The court concludes that "the regulation does not conflict with [its] reading of the statute," 36 which assumes that a prisoner is ultimately liable for the entire cost of all medical services received by the prisoner. But the court never addresses the conspicuous lack of assignment of personal financial responsibility in subsection (b)(2) of the regulation or the indirect phrasing of "arrange for." If the fact that a prisoner is potentially a "responsible party set out in AS 33.30.028" made the prisoner personally responsible for payment for outside care even without collateral sources, it would be an odd turn of phrase indeed to assign personal liability to a prisoner by directing the prisoner to "arrange for ... payment" from himself, particularly when DOC in the immediately prior subsection of the regulation has already demonstrated that it knows how to assign personal liability directly.
In my view, the language and legislative history of AS 88.30.028 are sufficiently clear that I would hold for Hendricks-Pearee on their strength alone. But even if the statute's meaning were ambiguous in this case, DOC's longstanding interpretation of AS 33.30.028 should resolve any lingering ambiguity.37 (That DOC has adopted a contrary *46interpretation of the statute during this litigation is of no moment.38)
The court dismisses the import of DOC's interpretation by invoking two mutually con-tradietory reasons. First, the court indicates that the "plain" text and "natural reading" suffice to reach its preferred interpretation, implying that there is no lingering ambiguity in the statutory text for the regulations to resolve. As I discuss above, the best reading of the statute's text and purpose clearly favors my interpretation, but, at the very least, the statute is ambiguous, and the court must address DOC's contrary interpretation. Second, without acknowledging the contradiction with the first reason, the court states that the statute is "silen[t]" on the assignment of personal liability for the cost of outside medical care where a prisoner lacks enumerated collateral resources.39 - The court then concludes that DOC's interpretation of the statute "properly goes no further" than the statute and "says nothing of divesting the prisoner lacking collateral resources of liability for outside services." 40 Not only is this argument as to statutory silence con-tradieted by the court's own argument about the plain meaning of the statutory text, it also contradicts itself: why would an interpretive regulation have to divest a prisoner of lability that is never assigned by the statute?
Finally, the court's interpretation of the statute creates a damaging policy that will undermine the State's fiscal and public safety interest in reducing recidivism and supporting prisoners' successful reentry into the community after release. When deciding questions of law, such as interpreting the meaning of a statute, we have repeatedly stated that "(olur duty is to adopt the rule of law that is most persuasive in light of precedent, reason, and policy."41 I would interpret AS 38.30.028 based on text, purpose, and administrative interpretation so that the statute enacts a reasonable policy: Prisoners will be deterred from frivolous over-consumption of medical services-both in-house and rendered outside the DOC system-while DOC will be able to recover costs when a prisoner has access to an enumerated source of coverage or benefits.
As the court interprets AS 88.30.028 today, the statute would inflict significant harms to the State's interests and to the individual liberty of former prisoners who have completed their sentences. When a prisoner receives substantial medical care that is uncompensated by collateral sources, DOC will be in the position of superintending the person's ability to save any money at all, starting while the person is in prison and extending indefinitely after release. If a former prisoner is lucky enough to reintegrate successfully and obtain a modicum of savings to secure a stable life, DOC will be able to seek reimbursement under AS 38.80.0228 years after release. In effect, DOC will have the power to prevent any former prisoner who received unreimbursed care from achieving more than a subsistence existence until the unreim-bursed cost of care is paid back. The logic of this claimed power would also seem to permit the State to withhold virtually any form of government assistance, including Permanent Fund Dividend payments, government salary disbursements, unemployment benefits, payments provided under contract, and welfare payments. It would also seem to permit the State to seek repayment by forcing former prisoners to liquidate their meager assets or borrow against future earnings from licenses or other non-tangible assets or unrealized gains.
I would conclude that the statute's text, purpose, and administrative interpretation *47foreclose this result. The statutory text and legislative history make clear that the legislators thought they were passing a bill with only minimal charges for prisoners that would have the deterrent effect of a copayment for a subset of medical services.42
The court's policy choice will harm the State's interests in reducing ex-offender recidivism, protecting public safety, and safeguarding the public fise. Personal financial resources are a crucial determinant of sue cessful prison reentry and recidivism prevention.43 Reducing recidivism protects public safety by preventing future crime, and it also reduces State spending on investigation, prosecution, defense, and punishment stemming from the commission of future crimes.44 It was thus reasonable for the legislature to adopt statutory text with the effect of limiting personal liability for outside healthcare expenditures. The court's reconstruction of AS 33.30.028 institutes a new policy, one that harms these important State goals.
For these reasons, I would hold that AS 83.30.028 does not impose personal liability on prisoners for the cost of health care rendered by professionals outside of the DOC system where the person lacks a collateral source enumerated in AS 83.30.028(a). I would reverse the superior court and remand. I therefore respectfully dissent and do not join the plurality opinion.

In order to have the third-party deemed "responsib[le]" by AS 33.30.028(a), the prisoner must already be eligible for benefits from a public agency or have an insurance plan that covers such costs.

. Staffer Dennis DeWitt testified to the House Finance Committee that the statute is "designed to act as a deterrent to frivolous complaints."
