NAIC AI Model Bulletin Insurer Testing Guide
The NAIC bulletin tells insurers that existing unfair trade practice and claims settlement laws apply to decisions made or supported by AI, and that regulators will expect a written AI Systems program with testing, validation and documentation. For agent teams, that means evidence that claims and underwriting decisions are accurate, non-discriminatory and explainable, available on request in a market conduct exam.
- Instrument
- NAIC Model Bulletin: Use of Artificial Intelligence Systems by Insurers
- Primary citation
- NAIC Model Bulletin on the Use of Artificial Intelligence Systems by Insurers (adopted 4 December 2023), Sections 3 and 4
- Authority
- State insurance departments, via the National Association of Insurance Commissioners model
- Status
- As of November 2026: adopted by the NAIC on 4 December 2023 and adopted in some form by roughly half the states plus the District of Columbia, some with modifications. NAIC work on a possible AI model law and on third-party AI oversight continues; check each state's adopted version.
Statutory requirements
- 01
Existing law applies to AI-supported decisions
Bulletin, Section 1 (legislative authority)The bulletin reminds insurers that decisions affecting consumers made or supported by AI must comply with applicable insurance laws, including unfair trade practices, unfair claims settlement practices, corporate governance disclosure, rating laws and market conduct surveillance. A claims agent that misstates coverage or delays payment without reasonable basis is evaluated under the same laws as a human adjuster.
- 02
Written AIS program
Bulletin, Section 3Insurers are expected to develop, implement and maintain a written program for the responsible use of AI systems that make or support decisions related to regulated insurance practices. The program should be designed to mitigate the risk of adverse consumer outcomes, including inaccuracy, unfair discrimination and data vulnerability, and should be proportionate to the risk.
- 03
Governance and risk management controls
Bulletin, Section 3The program should address governance (roles, accountability, cross-functional oversight), and risk management and internal controls across the lifecycle: data practices, validation, testing and retesting, model drift monitoring, and documentation of the outcomes of testing. Controls should scale with the degree of potential harm to consumers.
- 04
Third-party AI systems and data
Bulletin, Section 3 (third-party AI systems and data)Insurers remain responsible for outcomes of AI systems and data acquired from third parties. The bulletin expects due diligence on vendors, contract terms that allow audit and cooperation with regulators, and the insurer's own validation where possible. Liability for the outcome does not transfer by contract.
- 05
Regulatory oversight and examinations
Bulletin, Section 4In investigations and market conduct exams, regulators may request documentation of the AIS program, the inventory of AI systems, testing and validation results, and information about third-party systems. Evidence that only exists in an engineer's notebook is hard to produce on a deadline.
Evaluation methodologies
Coverage interpretation accuracy
Test the agent against policy forms and endorsements with expert-labelled outcomes (covered, excluded, needs adjuster review), including the edge cases licensed adjusters and coverage counsel flag: anti-concurrent causation clauses, sublimits, endorsements that override base form language.
Claims settlement trajectory checks
Assert the agent requests only necessary documentation, acknowledges and routes within the timeframes your state unfair claims practice rules require, and never denies without the decision steps your procedures specify.
Unfair discrimination testing
Run matched-pair FNOL and underwriting cases that vary prohibited or sensitive characteristics, and compute outcome disparities where data permits. States such as Colorado have specific governance and testing rules for some lines; map them where you write business.
Vendor model validation
Evaluate third-party models black-box on your own golden set before adoption and on each vendor update, and record what the vendor provided and what you could not verify.
Testing artifacts to retain

NAIC AI Bulletin testing questions
Is the NAIC bulletin binding?
The NAIC model is not binding on its own. It applies where a state insurance department has adopted it, and the laws it references are binding regardless. Check each state's adopted text. This guide is not legal advice.
Does a vendor's SOC 2 report satisfy third-party AI oversight?
No. SOC 2 covers security and related controls, not whether the model's decisions are accurate or non-discriminatory for your book. You still need outcome testing on your own data.
Can an AI agent deny a claim?
State law and your own procedures decide. Many carriers require a licensed adjuster to make or confirm adverse decisions, and the bulletin expects controls proportionate to consumer harm. Test that the agent respects whatever boundary your procedures set.
