Hawaiʻi PIP Benefits Require Proof of Prepaid-Plan Comparability; Statutory Definitions Defeat “Ambiguity”

I. Introduction

Case: In the Matter of the Request for Payment of, Christopher Lawinski, M.D., as Provider for Sean Tilton v. Scott Saiki, Insurance Commissioner, Department of Commerce and Consumer Affairs, State of Hawaiʻi; and United Services Automobile Association, Supreme Court of Hawaiʻi (July 29, 2026).

This case arises from a no-fault insurance dispute over reimbursement for medical treatment following an automobile collision. After patient Sean Tilton was injured in a 2017 car crash, his provider, Dr. Christopher Lawinski, billed Tilton’s no-fault insurer, United Services Automobile Association (“USAA”), for six sessions of low level laser therapy (“LLLT”). USAA contested payment and dramatically reduced reimbursement by recoding the billed CPT code to a different modality code.

The dispute moved through Hawaiʻi’s administrative process: an Office of Administrative Hearings decision (adopted by the Insurance Commissioner), review in the circuit court, and affirmance by the Intermediate Court of Appeals (“ICA”). On certiorari, the Hawaiʻi Supreme Court focused on two questions: (1) whether LLLT was a covered personal injury protection (“PIP”) benefit under HRS § 431:10C-103.5(a), and (2) whether the statute was ambiguous and required interpretation.

The decision establishes (and emphatically clarifies) that Hawaiʻi’s PIP definition imposes two independent statutory conditions—and that where the legislature supplies a definition in the next statute, courts should not manufacture ambiguity. The court also underscores an evidentiary and burden-of-proof rule: the claimant/provider bears the burden to prove the “prepaid health care plan comparability” condition.

II. Summary of the Opinion

The Supreme Court affirmed the ICA’s judgment upholding the Commissioner’s final decision denying full reimbursement. Although Dr. Lawinski offered evidence suggesting LLLT was effective and medically beneficial, he presented no evidence that LLLT was “substantially comparable to the requirements for prepaid health care plans,” as required by HRS § 431:10C-103.5(a). Because the statute requires both (1) appropriateness/reasonableness/necessity and (2) substantial comparability to prepaid plan requirements, the lack of proof on the second condition was dispositive.

The court also corrected the ICA’s analytical framing: the ICA treated the “substantially comparable” phrase as ambiguous and then used HRS § 431:10C-103.6 to resolve that ambiguity. The Supreme Court held this was wrong in principle: a term the legislature defines is not ambiguous; the definition supplies the meaning.

III. Analysis

A. The Statutory Holding: Two Conditions, Not One

The core doctrinal contribution is the court’s insistence on the conjunctive structure of HRS § 431:10C-103.5(a). “Personal injury protection benefits” mean:

“all appropriate and reasonable treatment and expenses necessarily incurred as a result of the accidental harm and which are substantially comparable to the requirements for prepaid health care plans[.]” (HRS § 431:10C-103.5(a))

The word “and” does the work: the court treats the definition as creating two independent prerequisites. Even if a service is medically reasonable and necessary, it is not a PIP benefit unless it also satisfies the prepaid-plan comparability requirement.

B. “Substantially Comparable” Is Defined—So It Is Not Ambiguous

The Supreme Court held HRS § 431:10C-103.5(a) is unambiguous because the legislature defined the comparability concept immediately in HRS § 431:10C-103.6(a):

“The benefits provided under section 431:10C-103.5 shall be substantially comparable to the requirements for prepaid health care plans, as provided in chapter 393 and rules of the department of labor and industrial relations, pertaining to the Prepaid Health Care Act. The reference to the Prepaid Health Care Act is only for purposes of describing the coverages and exclusions[.]” (HRS § 431:10C-103.6(a))

This is not merely a textual point; it is a methodological directive: courts should not label statutory language “ambiguous” when the legislature has provided an operative definition. Definitional sections exist to remove doubt, and treating defined terms as ambiguous would incorrectly render “every defined term ambiguous and every definition section a fresh source of uncertainty.”

C. Proof and Burden: The Provider Must Prove Prepaid-Plan Comparability

The court’s evidentiary holding is direct: Dr. Lawinski “had the burden on both conditions.” On the second condition, the record showed:

  • Dr. Lawinski’s witness conceded he had “no idea” whether any prepaid plan in Hawaiʻi covers LLLT.
  • Dr. Lawinski acknowledged no prepaid plan had ever covered his LLLT and he had never billed one.
  • No evidence was offered that LLLT is reimbursed under HRS chapter 393 / DLIR rules or that it aligns with benchmark plan coverage.

Therefore, “No proof, no recovery.” Importantly, the court rejects the notion that FDA clearance, clinical effectiveness, or “medical necessity” evidence can substitute for proof of prepaid-plan comparability. Those facts bear on condition (1), not condition (2).

D. Precedents Cited (and How They Shaped the Decision)

1. Allstate Ins. Co. v. Schmidt

Cited for the standard of review in a “secondary appeal” from an agency decision under HRS § 91-14(g). The court uses Allstate Ins. Co. v. Schmidt, 104 Hawaiʻi 261, 264, 88 P.3d 196, 199 (2004), to anchor its posture: the Supreme Court reviews the Commissioner’s decision under the administrative appeal framework, while reserving de novo review for pure questions of law like statutory interpretation.

2. Rosehill Trustee of the Linda K. Rosehill Revocable Tr. dated August 29, 1989 v. State

Cited to reaffirm that statutory interpretation is reviewed de novo. This supports the Supreme Court’s willingness to correct the ICA’s reasoning about ambiguity and definitional statutes, even while reaching the same ultimate outcome on coverage.

3. State v. Ontai

State v. Ontai, 84 Hawaiʻi 56, 60, 929 P.2d 69, 73 (1996), is deployed for a basic but powerful interpretive rule: when the legislature defines a word or phrase, courts apply that definition. The Supreme Court uses Ontai to rebut the ICA’s approach, emphasizing that definitional provisions are the first stop in determining meaning—not a tool to be used only after declaring ambiguity.

4. Courbat v. Dahana Ranch, Inc.

Courbat v. Dahana Ranch, Inc., 111 Hawaiʻi 254, 261, 141 P.3d 427, 434 (2006), supports the court’s refusal to consult legislative history where statutory language is clear. This is central to rejecting Dr. Lawinski’s “generous benefits” argument based on asserted legislative purpose. The court’s message is that “purpose” cannot override unambiguous statutory text—especially where the text imposes a distinct coverage-limiting condition.

5. State Farm Mut. Auto. Ins. Co. v. Gepaya

State Farm Mut. Auto. Ins. Co. v. Gepaya, 103 Hawaiʻi 142, 148, 80 P.3d 321, 327 (2003), is invoked to contextualize the 1997 statutory amendment. The court uses Gepaya to show the amendment’s purpose: controlling costs and narrowing coverage by tying PIP benefits to prepaid health care plan requirements. That context undercuts Dr. Lawinski’s position that the statute should be read expansively to cover “every reasonable treatment.”

6. Richard v. Metcalf and Gamata v. Allstate Ins. Co.

These cases are crucial, not because they control, but because the Supreme Court explains why they do not. Dr. Lawinski cited Richard v. Metcalf, 82 Hawaiʻi 249, 921 P.2d 169 (1996), and Gamata v. Allstate Ins. Co., 90 Hawaiʻi 213, 978 P.2d 179 (1999), for the proposition that reasonableness/necessity suffices.

The court distinguishes both: they construed the pre-1997 statute, which lacked the “substantially comparable” clause. It further notes Gamata recognized the definition was later “moved and narrowed.” Thus, older PIP jurisprudence emphasizing “reasonable and necessary” cannot be imported into the post-1997 statutory scheme without accounting for the added comparability limitation.

E. Legal Reasoning: Text, Structure, Definitions, and Amendment History

The court’s reasoning proceeds in a disciplined sequence:

  1. Text and grammar: HRS § 431:10C-103.5(a) uses a conjunctive structure (“and”), creating two requirements.
  2. Definition controls meaning: HRS § 431:10C-103.6(a) defines what “substantially comparable” means by reference to HRS chapter 393 and DLIR rules under the Prepaid Health Care Act (explicitly “only for purposes of describing the coverages and exclusions”).
  3. No legislative history when unambiguous: Under Courbat, clarity ends the inquiry.
  4. Even if consulted, history confirms narrowing intent: The 1997 amendment added the comparability clause and was meant to rein in costs, consistent with Gepaya. A statute that was broadened rhetorically (by “generous” framing) was, in fact, narrowed legally.
  5. Application to the record: Effectiveness and FDA clearance do not prove prepaid-plan comparability; the provider presented no evidence satisfying condition (2).

A notable feature is the court’s institutional concern: it corrects the ICA’s “ambiguity-first” framing not just for this case, but to prevent the method from “travel[ing]” into other statutory contexts. The opinion thus reads as both a PIP-coverage ruling and a broader interpretive directive about the role of definitional provisions in Hawaiʻi statutes.

F. Impact: What This Decision Likely Changes (and Clarifies)

1. For PIP litigation and provider billing disputes

  • Providers must build a comparability record: Claimants seeking payment for therapies—especially newer, “unlisted,” or nonstandard modalities billed under codes like CPT 97039—should expect that proving medical reasonableness is insufficient. They must also show the service is “substantially comparable” to prepaid-plan coverages/exclusions tied to HRS chapter 393 and DLIR rules.
  • Strategic evidence shifts: The most probative evidence may include testimony or documentation about whether Hawaiʻi prepaid health care plans cover the modality, how the benchmark plan under HRS § 393-7(a) treats it, and whether exclusions apply under PHCA-related rules.
  • Insurer defenses strengthened: Insurers can defeat claims by targeting the second statutory prong, even where necessity and reasonableness are hard to dispute.

2. For statutory interpretation in Hawaiʻi

  • Definitions as anti-ambiguity tools: Courts and litigants should treat definitional provisions as conclusive on meaning, not as a cure for a supposedly ambiguous term. This supports more predictable statutory construction across the Hawaiʻi Revised Statutes.
  • Reduced resort to purposivism: The opinion reinforces that legislative purpose arguments cannot displace unambiguous text, particularly where amendments demonstrate narrowing.

IV. Complex Concepts Simplified

1. “PIP benefits” (Personal Injury Protection benefits)

PIP is no-fault auto insurance coverage that pays certain medical expenses regardless of fault. In Hawaiʻi, the scope of what must be paid is governed by statutory definitions—not simply by a provider’s clinical judgment.

2. “Appropriate, reasonable, and necessarily incurred”

This first prong asks whether the treatment makes medical and practical sense for the accident injury: was it reasonable in type and cost, and necessary because of the crash?

3. “Substantially comparable to the requirements for prepaid health care plans”

This second prong is a coverage-limiting benchmark: PIP must be similar to what Hawaiʻi prepaid health care plans are required to cover (and allowed to exclude) under the Prepaid Health Care Act framework (HRS chapter 393 and DLIR rules). A treatment can be helpful and still fall outside PIP if it is not comparable to that benchmark.

4. “Ambiguity” and “definitions” in statutes

A statute is “ambiguous” when its meaning is genuinely uncertain. If the legislature provides a definition, that definition resolves uncertainty. This case emphasizes that courts should not call a defined phrase ambiguous merely because they must read the definitional section to understand it.

5. “Secondary appeal” and “de novo review”

Because this case comes from an agency decision (the Insurance Commissioner), courts apply administrative review rules. Factual and discretionary determinations often receive deference under HRS § 91-14(g), but statutory interpretation is reviewed “de novo,” meaning fresh, without deference.

V. Conclusion

The Hawaiʻi Supreme Court’s decision delivers two key takeaways:

  • PIP coverage has two mandatory prongs under HRS § 431:10C-103.5(a): (1) the treatment must be appropriate, reasonable, and necessarily incurred due to the accident, and (2) it must be substantially comparable to prepaid health care plan requirements as defined by HRS § 431:10C-103.6(a). Proof of the first cannot substitute for proof of the second.
  • Statutory definitions defeat ambiguity: the ICA’s approach—declaring a defined phrase ambiguous and then using the definition to resolve it—was rejected as doctrinally backwards and potentially disruptive across Hawaiʻi law.

In practical terms, the ruling narrows the path to reimbursement for nontraditional or emerging therapies under Hawaiʻi PIP: providers must be prepared to prove not only clinical merit, but also statutory comparability to prepaid-plan coverage requirements. In interpretive terms, the case stands as a strong reaffirmation that when the legislature defines, courts apply—without manufacturing ambiguity that the definition was designed to eliminate.
