Insurance Curator 
The doctrine of utmost good faith (uberrimae fidei) is foundational to insurance law and is particularly significant in Hawaii health insurance. It requires both insurer and insured to act honestly and disclose material facts that could influence underwriting or claims decisions. In Hawaii, this duty intersects with statutory obligations like HRS 431:10-209, which focuses on medical truthfulness and applicant disclosures.
What "Utmost Good Faith" Means in Health Insurance
Utmost good faith goes beyond ordinary honesty; it imposes a duty to disclose all material facts that a reasonable insurer would consider relevant. For health applications, this often means reporting prior diagnoses, treatments, medications, specialist visits, and relevant family history. Failure to meet this duty can lead to serious consequences, including claim denials or contract rescission.
Hawaii law recognizes and enforces this principle through regulations and case law. For more on the statute that frames medical disclosures in Hawaii, see Hawaii HRS 431:10-209: The Requirement for Medical Truthfulness.
Why Pre-Existing Condition Non-Disclosure Is Risky
Non-disclosure of a pre-existing condition is one of the most common breaches of utmost good faith. Insurers rely on applicant statements to assess risk and set premiums. When applicants omit or misstate material medical history, insurers may view the omission as:
- Intentional fraud designed to obtain lower premiums.
- A material misrepresentation that would have changed underwriting decisions.
- An actionable basis for rescission or denial of coverage.

How Hawaii's HRS 431:10-209 Shapes Disclosure Obligations
HRS 431:10-209 emphasizes medical truthfulness in health insurance applications. The statute and related administrative guidance require truthful, complete medical disclosures to protect both consumers and insurers. Hawaii’s framework intends to preserve the integrity of the insurance marketplace while preventing abusive rescissions.
For a practical overview of how this statute protects market integrity, see How HRS 431:10-209 Protects the Hawaii Insurance Marketplace.
Materiality: What Hawaii Courts Consider Important
Materiality determines whether an omission justifies insurer action. Hawaii courts assess whether the undisclosed fact would have influenced the insurer’s decision to issue the policy, or the terms of coverage. The assessment can be highly factual and looks at timing, relevance, and the insurer’s underwriting criteria.

Typical Legal Consequences for Non-Disclosure
Consequences for failing the duty of utmost good faith can range from administrative corrections to severe legal remedies. Below is a comparison table summarizing common insurer responses.
| Insurer Response | What It Means | Typical Effect on Insured |
|---|---|---|
| Claim Denial | Insurer refuses payment for a specific claim | Financial loss for insured; may be contestable |
| Rescission | Policy voided ab initio (treated as never issued) | Loss of coverage; premiums often refunded, claims denied |
| Cancellation/Nonrenewal | Policy terminated for future coverage | Loss of coverage going forward; market difficulty obtaining replacement |
| Civil Fraud Action | Insurer sues for fraud or damages | Potential civil liability, legal costs, and reputational harm |
| Criminal Referral | Severe intentional fraud may be referred to prosecutors | Possible criminal charges in extreme cases |

How Insurers Investigate and Prove Non-Disclosure
Insurers use medical records, prescription histories, specialist notes, and investigative tools to verify application statements. Common triggers for investigation include:
- Inconsistencies between application answers and medical records.
- Claims submitted shortly after policy issuance.
- Third-party tip-offs or data matches from prescription databases.
When an insurer believes non-disclosure occurred, it must show the omission was material and, in some cases, intentional. For insights into contested rescissions, see Challenging a Rescission Notice in Hawaii Under Section 431.
Practical Steps for Applicants — Preventing and Responding to Problems
To reduce risk and strengthen your position if questioned, follow these steps:
- Be thorough: Disclose all known medical issues, treatments, medications, and specialist visits when completing applications.
- Keep records: Maintain copies of applications, medical records, and communications with insurers.
- Correct mistakes promptly: If you discover an unintentional omission, notify the insurer and provide supporting documentation.
- Seek legal help: If faced with rescission or denial, consult an attorney experienced in Hawaii insurance law.

Defending Against a Rescission or Denial
A policyholder’s defenses often focus on lack of materiality, ambiguity in application questions, or good-faith mistakes. Evidence that the insurer had actual knowledge of the condition or that the omission could not have influenced underwriting can be persuasive.
If you face a denial, consider these actions:
- Request the insurer’s complete file and justification for rescission.
- Obtain and submit medical records that clarify the timeline or severity.
- Challenge the insurer’s interpretation of application questions.

Best Practices for Brokers, Providers, and Consumers
All parties share responsibility for upholding utmost good faith. Recommended best practices include:
- Brokers: Review applications line-by-line with applicants and document your advice.
- Providers: Respond promptly to valid records requests and ensure accurate billing.
- Consumers: Ask questions if application language is unclear and get written confirmations.
