Understanding the Insurance 90-Day Waiting Period: What You Need to Know

Insurance 90-Day Waiting Period

Insurance policies often include waiting periods as part of their coverage terms. One such waiting period commonly found in health insurance plans is the 90-day waiting period. This period refers to the duration during which an individual must wait before certain benefits become effective under the insurance policy.

In this article, we will explore the concept of the insurance 90-day waiting period, its purpose, and what you need to know about it.

What is the Insurance 90-Day Waiting Period?

The insurance 90-day waiting period is a predetermined period specified in a health insurance policy during which coverage for certain benefits is temporarily withheld.

It starts from the date the policy becomes effective or the date an individual becomes eligible for coverage, whichever is later.

During this waiting period, individuals are not entitled to receive benefits for specific services or treatments outlined in the policy.

Purpose of the Waiting Period

The primary purpose of the insurance 90-day waiting period is to prevent individuals from enrolling in a health insurance plan solely to receive immediate coverage for costly medical services.

By implementing a waiting period, insurance companies can protect themselves against adverse selection, which refers to the situation where individuals sign up for insurance only when they anticipate needing expensive medical treatments.

The waiting period ensures that individuals maintain coverage for an extended period and contributes to the stability and sustainability of insurance plans.

What Does the Waiting Period Apply To?

The specific benefits or services subject to the insurance 90-day waiting period can vary depending on the insurance policy. Commonly, waiting periods apply to services such as major dental work, orthodontic treatment, vision correction procedures, pre-existing conditions, and certain elective surgeries. These are typically services or treatments that require significant financial investment or have a higher likelihood of being sought immediately after obtaining coverage.

Exceptions and Limitations

It’s important to note that not all insurance plans have a 90-day waiting period, and the duration of waiting periods can vary. Some plans may have shorter or longer waiting periods, while others may waive waiting periods altogether. Additionally, waiting periods may not apply to certain individuals or circumstances.

For example, individuals who had prior insurance coverage or experienced a qualifying event such as marriage or birth may be exempt from the waiting period. It is crucial to carefully review the terms and conditions of your insurance policy to understand the specifics of the waiting period and any exceptions or limitations that may apply.

Navigating the Waiting Period

During the insurance 90-day waiting period, individuals are still eligible for coverage for other services not subject to the waiting period. It’s important to understand which services are covered and which are not during this period to effectively manage your healthcare needs. Additionally, individuals can take advantage of preventive care services that are often exempt from waiting periods, such as routine check-ups, vaccinations, and screenings.


The insurance 90-day waiting period serves as a mechanism to ensure the stability of insurance plans and protect against adverse selection. While it may temporarily delay coverage for certain benefits or services, it helps maintain the long-term sustainability of insurance policies.

It is crucial to familiarize yourself with the waiting period stipulations in your health insurance policy, including any exceptions or limitations that may apply. By understanding the waiting period and its implications, you can make informed decisions about your healthcare needs and effectively navigate your insurance coverage.
