What it means
Insurers worry that people will buy cover only when they know they need it. If anyone could join after being diagnosed and claim immediately, premiums would have to rise for everybody.
An exclusion period is one way of limiting this risk. During the period the plan treats claims for the existing condition as outside its cover.
The patient pays for that treatment, or relies on another source of cover. Claims for new problems that arise after joining are usually paid in the normal way.
How the period works depends on the plan. It may last a few months or a year or more, and it often applies only to conditions diagnosed or treated within a set look-back period before joining.
Some plans reduce the period by the time you had previous cover, which is called credit for prior coverage. For employers and finance teams, these periods affect the real value of benefits offered to new staff.
A group plan with a long exclusion period gives less protection to a new joiner who has an ongoing condition, which may matter for recruitment. When switching insurers, a company should check that employees do not start a fresh exclusion period.
The same idea appears in life, travel, disability and long-term care policies. In the health sector, many jurisdictions have restricted or banned these exclusions for certain plans, so people should check the rules that apply to their own policy.
Reading the definition of pre-existing in the contract is essential, since it varies. Disclosure is just as important as the waiting time.
Applications ask about past illnesses, and failing to mention one can give the insurer grounds to refuse a claim or cancel the policy. Honest answers protect the buyer, even if they lead to higher premiums or a longer exclusion.
In practice
Real-world examples.
Example
A man with diabetes joins a new private health plan that has a 12-month exclusion period. For the first year he pays for his diabetes supplies himself, while any new illness is covered. After the period ends, his diabetes treatment is covered, subject to the plan's usual limits.
Example
A small business moves its staff from one group insurer to another. The broker negotiates that service with the old insurer counts as prior coverage, so no employee has to start a new exclusion period. This saves several staff members thousands of dollars in treatment costs.
Example
A woman buys a travel policy before a trip and has a heart condition under treatment. The insurer excludes claims related to that condition, so she buys a policy with an additional medical cover for a higher premium. She reads the definition of pre-existing carefully before paying.
Formula
Calculation
Remaining exclusion period = Plan exclusion period - Months of creditable prior coverage (not below zero)
A plan has a 12-month exclusion period for pre-existing conditions. A new employee had 8 months of continuous cover with her previous insurer.
Remaining exclusion period = 12 - 8 = 4 months.
During those 4 months a claim for her existing condition would not be paid, so if the treatment costs $1,500 a month she would pay $1,500 x 4 = $6,000 herself before the plan begins to pay.Case study
Seen in the real world.
Pinecrest Staffing is a fictional agency that offered health benefits to its temporary workers. Its plan carried a six-month exclusion period for existing conditions, which several workers did not notice when they enrolled.
One worker needed treatment in her second month and faced a bill of $9,000 that the plan would not pay. In this illustrative case, the agency changed to a plan that credited prior coverage, explained the exclusion rules in its onboarding pack and added a reminder to its enrolment form.
The finance director noticed that complaints fell and staff turnover eased. She concluded that clear information about exclusions was as valuable as the benefit itself. The agency also began to ask new workers to bring any certificate of previous cover, which often shortened their waiting period. Within a year the agency's staff surveys showed higher satisfaction with its benefits, even though the plan itself had barely changed.
Watch out
Common mistakes.
- Assuming that all conditions are covered from the first day of a policy.
- Not telling the insurer about an existing condition, which can lead to a claim being refused later.
- Letting cover lapse before switching, which can start a new exclusion period.
Questions
People also ask.
Does the exclusion period apply to all conditions?
No, only to those that existed before the start of the cover, as defined in the policy.
Can the period be shortened?
Often yes, through credit for prior coverage, or by negotiating terms in a group plan.
Are these periods allowed everywhere?
Rules vary by country and by type of plan, and some places restrict or ban them, so check the rules that apply to your policy.
