Maine adopted the NAIC Pet Insurance Model Act in 2022, the same year the model was approved, which makes it the reference implementation: where later states are compared, they are compared to this one. The obligations are the model's own. Before the sale an insurer must disclose whether the policy excludes pre-existing conditions, hereditary disorders, congenital anomalies and chronic conditions, and must be clear about waiting periods. Because Maine moved immediately, it is also the jurisdiction with the longest run of policies actually written under the rules, which matters if you are looking for how the disclosure requirements behave in practice rather than on paper. This page describes what the law obliges an insurer to tell you before you sign. It does not say whether any particular policy is a good one, and it is not legal advice. We read the statute reference and the NAIC model-law status page on 1 September 2026. Most states have no pet-specific disclosure law at all. We only publish a page for a state where there is an actual statute to point at, which is why this register covers a handful of states rather than fifty.

What this rule does not do

Adopting the model does not standardise the products, only what must be said about them. Two insurers can offer a 14 day and a 12 month orthopedic waiting period side by side in Maine and both comply, because the act regulates the telling rather than the term. It also leaves the definition of a bilateral condition entirely to the insurer, which is why the wording comparison on this site exists at all: the clause that most often decides a large claim is the one no state has yet written a rule for. There is a further gap that four years of operation have made visible. The act says what must be disclosed but not how prominently, so a compliant disclosure can still sit in a document a buyer receives after deciding. Being told is not the same as being told in time.

What can you actually do with it as a buyer?

The disclosure has to happen before the sale, so the moment to use it is while you are still deciding rather than after the documents arrive. Ask the insurer directly whether the policy excludes pre-existing conditions, hereditary disorders, congenital anomalies and chronic conditions, and ask for the answer in the wording rather than in a summary. Maine has had these rules in force longer than anywhere else, so an insurer selling here has no excuse for a vague reply. What the law will not do is give you a cooling-off period afterwards, which is why the reading has to come first. A practical tactic: ask for the specimen policy by its form code before quoting, then compare that code against whatever arrives after purchase. If they differ, you were shown a different contract from the one you bought.
