A pet insurance waiting period is the stretch of time after you buy a policy before some or all of its coverage kicks in. If your pet gets sick or hurt during a wait that applies to that kind of claim, you pay the vet yourself, and the problem can count as pre-existing afterward. Policies with no waiting period at all are the exception. But in states that have adopted the National Association of Insurance Commissioners (NAIC) pet insurance model law, accidents can’t have a waiting period, illness waits are capped at 30 days, and you can get the wait waived with a vet exam.

Here’s how waiting periods work, what the rules say, what to watch for in a “no waiting period” policy, and how to time your enrollment so the wait doesn’t catch you out.

What is a pet insurance waiting period?

The NAIC’s Pet Insurance Model Act (Model #633) defines a waiting period as “the period of time specified in a pet insurance policy that is required to transpire before some or all of the coverage in the policy can begin.”

In plain English, you buy the policy and start paying, but the insurer won’t pay claims for certain problems until the clock runs out. If your cat gets a urinary infection during an illness waiting period, for example, that vet bill is yours.

It can also follow you after the wait ends. The model law defines a pre-existing condition as one where a vet gave advice, your pet was treated, or your pet had signs or symptoms directly related to the condition, either before the policy started or during any waiting period. So a problem that first shows up during the wait can be excluded for good, the same as one from before you bought. Most pet insurers exclude pre-existing conditions, according to the NAIC.

How long are pet insurance waiting periods?

The length depends on the insurer, the state and the kind of claim. Many policies run separate clocks:

Type of claim How policies commonly handle it Under the NAIC model law
Accidents The shortest wait, sometimes none No waiting period allowed
Illnesses A longer wait than for accidents 30 days at most
Orthopedic conditions not caused by an accident Sometimes a separate, longer wait 30 days at most

The model law defines orthopedic conditions as ones affecting “the bones, skeletal muscle, cartilage, tendons, ligaments, and joints.” It names elbow dysplasia, hip dysplasia, intervertebral disc degeneration, patellar luxation and ruptured cranial cruciate ligaments as examples. It doesn’t include cancers or metabolic, hemopoietic (blood-forming) or autoimmune diseases.

Outside states with these rules, the exact number of days for each type is up to the insurer, within whatever rules your state sets. The only reliable number is the one in the policy you’re looking at, so read its waiting period section before you buy. The model law requires insurers to disclose waiting periods clearly and prominently before you purchase, and the Alabama Department of Insurance lists “Is there a waiting period before coverage becomes effective?” among the questions to ask any insurer.

What the NAIC model law says about waiting periods

The NAIC adopted its Pet Insurance Model Act in summer 2022. A model act is a template for state lawmakers, so it only has force in states that pass it. Here’s what its waiting period rules say:

  • A policy can have waiting periods of up to 30 days for illnesses or orthopedic conditions not resulting from an accident.
  • Waiting periods for accidents are prohibited.
  • An insurer that uses a waiting period has to let you waive it by completing a medical exam, which the insurer can require be done by a licensed vet after you buy.
  • You pay for that exam unless the policy says the insurer will.
  • The insurer can specify what the exam includes and require documentation, as long as its requirements don’t unreasonably restrict your ability to waive the wait.
  • Waiting periods have to be disclosed clearly and prominently before you buy.
  • Waiting periods can’t be applied to renewals of existing coverage.
  • An insurer can’t require a vet exam for you to renew.

The model also gives you a 15-day free look. You can return the policy within 15 days of receiving it for a full refund, for any reason, as long as you haven’t filed a claim.

States that have written these rules into law

We checked four states’ own statute websites. Each has a pet insurance law that caps illness and orthopedic waiting periods at 30 days, bans waiting periods for accidents, and requires insurers to let you waive the wait with a vet exam:

  • Delaware, in Title 18, § 8805 of the Delaware Code.
  • Nebraska, in Revised Statute 44-6506, passed in 2023.
  • Rhode Island, in § 27-83-4 of its General Laws, effective January 1, 2026.
  • Vermont, in 8 V.S.A. § 7155, effective July 1, 2025.

Vermont and Rhode Island go a step further on when coverage starts. Vermont says coverage has to take effect no later than 12:01 a.m. on the second calendar day after the premium is paid. Rhode Island sets the same second-day rule from the date of purchase, with a few exceptions, such as when the insurer is underwriting a specific pet or when coverage comes through an employer.

Other states may have similar laws. If yours isn’t on this list, your state insurance department can tell you what applies where you live.

Why “no waiting period” pet insurance is rare

Waiting periods exist to stop people from buying a policy after their pet is already sick or hurt. Without one, an insurer would be paying for problems that started before the policy did, and everyone’s premiums would have to cover that.

In states that follow the model law, every policy already has no waiting period for accidents, because the law bans one. What’s worth comparing there is how each policy handles illnesses and orthopedic conditions.

If you see a policy advertised with no waiting period, check these five things before you buy.

Is there a delayed start date instead? Vermont and Rhode Island both let a policy with no waiting period set its effective date up to 15 calendar days after purchase, as long as the date is clearly disclosed and no premium is earned before coverage begins. A policy can have “no waiting period” and still not cover your pet for up to two weeks.

Which coverage has no wait? It might apply to accidents only, with the usual wait for illnesses and orthopedic problems.

Does it require a vet exam to start? The model law requires insurers to disclose any exam needed to put coverage in place and to warn you that what the exam finds may lead to a pre-existing condition exclusion.

How does it define pre-existing? A short or missing waiting period doesn’t help much if the policy looks back a long way at your pet’s history.

What does it cost? Compare the price against a similar policy with a standard wait. Our pet insurance cost guide shows what average premiums look like.

How to get a waiting period waived

In states that follow the model law, any insurer that uses a waiting period has to offer a way to waive it with a medical exam. Elsewhere, it’s up to the insurer, so ask.

Here’s how it usually works under the model. You buy the policy, then take your pet to a licensed vet for an exam that covers whatever elements the insurer specifies. You send the insurer the documentation. You pay for the exam unless the policy says the insurer will.

There’s a trade-off. Anything the vet notes at that exam, such as a heart murmur or a sore joint, is now documented. Under the model’s definition, a condition with signs or symptoms during the waiting period can count as pre-existing. So the exam can shorten your wait, but it can also put something on the record. If your pet seems healthy, that’s usually a fair trade. If you already suspect a problem, it likely won’t be covered either way.

How to time your pet insurance enrollment

The single best move is to buy before you need it. The waiting period starts when the policy takes effect, so if you enroll while your pet is healthy, the clock can run out before anything goes wrong.

For a new puppy or kitten, enroll as soon as the insurer allows. Each insurer sets its own minimum age. A young pet has a short medical record, so there’s little to exclude, and any waiting period passes early. Our guide to pet insurance for cats covers the kitten years in more detail.

For an older pet, decide sooner rather than later. Each new diagnosis adds to the record a new policy can look back on, so waiting only makes the list of exclusions longer. Our guide to pet insurance for older dogs explains how age limits and pre-existing rules work for seniors.

Keep your coverage continuous. Under the model law, waiting periods can’t be applied to renewals, so staying with the same insurer means you only wait once.

Think twice before switching insurers. The model defines a renewal as a new policy from the same insurer or an affiliated one, so a policy from a different company is a fresh start with new waiting periods and a new look at your pet’s history. If you do switch, consider keeping the old policy active until the new one’s waiting periods are over, so you’re not left without coverage.

Use the free look. In states that follow the model, you have 15 days after you receive the policy to read it and return it for a full refund if you haven’t filed a claim.

Routine care is a separate question. Vaccines and spaying aren’t covered by a standard plan at all, whatever the waiting period, which we explain in does pet insurance cover spaying and vaccines.

When you’re ready, compare pet insurance quotes and check each policy’s waiting periods side by side. For more guides, head to our pet insurance hub.

Frequently asked questions

Is there pet insurance with no waiting period?

It’s rare. In states that follow the NAIC model law, such as Delaware, Nebraska, Rhode Island and Vermont, accident coverage can’t have a waiting period, and illness waits are capped at 30 days and can be waived with a vet exam. A policy with no waiting period may still set its start date up to 15 days after you buy in Vermont and Rhode Island, so check the effective date.

How long is the waiting period for pet insurance?

It depends on the insurer, the state and the type of claim. Accidents usually have the shortest wait, illnesses a longer one, and some policies set a separate wait for orthopedic conditions. Under the NAIC model law, accidents can’t have a waiting period, and illness and orthopedic waits can’t exceed 30 days.

Can a pet insurance waiting period be waived?

Often, yes. In states that follow the NAIC model law, an insurer that uses a waiting period has to let you waive it by having your pet examined by a licensed vet after you buy. You pay for the exam unless the policy says the insurer will. Anything the vet finds could be treated as pre-existing.

What happens if my pet gets sick during the waiting period?

The policy won’t pay for it, and the condition will likely be treated as pre-existing from then on. The NAIC model law’s definition of a pre-existing condition covers one that showed signs or was treated during a waiting period, as well as before the policy started.

Do waiting periods apply to accidents?

In states that follow the NAIC model law, no. Waiting periods for accidents are prohibited there. Elsewhere, a policy can set a short waiting period for accidents, so check yours.

Does the waiting period start over when I renew?

Not under the NAIC model law. It says waiting periods can’t be applied to renewals of existing coverage, and insurers can’t require a vet exam to renew.

If I switch pet insurance companies, do I get a new waiting period?

Most likely. The NAIC model law defines a renewal as a policy from the same insurer or an affiliated one, so a policy from a new company is new coverage, with its own waiting periods and pre-existing condition rules.
