When you take out private health insurance, one of the most important decisions you'll make is how your medical history is assessed. This process is known as medical underwriting. Understanding how underwriting works can help you choose the right policy and avoid unexpected exclusions later on.
Here, we explain what medical underwriting means, the different types available, and what you need to consider if you already have health insurance coverage.
What Medical Underwriting Means In Health Insurance
Medical underwriting is the process insurers use to assess your health and medical history before deciding what your policy will cover. The aim is to identify any pre-existing conditions or previous symptoms that may affect future claims.
Medical underwriting helps insurers determine:
- Which conditions can be covered
- Which conditions may be excluded
- Whether any special terms apply
- How future claims will be assessed
The Main Types Of Medical Underwriting
The two most common types of medical underwriting are moratorium underwriting and full medical underwriting.
Both options provide access to private healthcare, but they handle your medical history differently.
Moratorium Underwriting
With moratorium underwriting, you don't need to provide detailed medical information when you apply for cover.
Instead, the insurer automatically excludes any medical condition for which you've experienced symptoms, sought advice, received treatment, or taken medication during a specific period before your policy starts. This period is usually the previous five years.
In some cases, these exclusions may be lifted after you've completed a continuous period without symptoms, treatment, medication, or medical advice. This timeframe is often two years, but it varies between insurers.
Moratorium underwriting offers a quicker and simpler application process, but it can sometimes lead to uncertainty when making a claim.
Full Medical Underwriting Explained
Full medical underwriting simply means providing detailed information about your medical history when you apply for cover.
You'll usually complete a health questionnaire that asks about:
- Previous medical conditions
- Current symptoms
- Medications you take
- Past treatments or investigations
- Family medical history in some cases
The insurer reviews this information before your policy begins and confirms exactly what is covered and excluded.
Although the application process takes longer, many people value the certainty that comes with knowing their policy terms from the outset.
Moratorium Vs Full Medical Underwriting
When considering moratorium vs full medical underwriting, it's important to remember that neither option is automatically better for everyone.
People who prefer a quicker application process may favour moratorium underwriting. Those who want clarity from the beginning may prefer full medical underwriting.
What Is Better Moratorium Or Full Medical Underwriting?
There isn't a single answer to the question, what is better moratorium or full medical underwriting.
The right choice depends on several factors, including:
- Your current health
- Your medical history
- Your willingness to complete medical questionnaires
- How important certainty is to you
- Whether you've had previous claims
For example, someone with a straightforward medical history may find moratorium underwriting convenient and suitable.
However, someone with ongoing conditions or previous health concerns may prefer full medical underwriting explained in advance, so they understand exactly where they stand.
Taking the time to compare both options can help you choose cover that meets your needs now and in the future.
Why Switching Underwriting Matters If You Already Have Cover
If you already have private health insurance, changing your underwriting method can have important consequences. Many people focus on premium costs when reviewing their cover, but underwriting terms can be just as important.
Switching insurers or changing from one underwriting type to another could affect how your medical history is treated. You may have developed conditions since taking out your original policy or made claims that need to be considered carefully.
Before making any changes, it's important to understand:
- How previous claims may affect your cover
- Whether existing exclusions will continue
- If your medical history can be transferred
- How new underwriting terms may apply
Seeking advice before making changes can help you avoid losing valuable benefits.
Which Underwriting Option Is Right For You?
Choosing between moratorium and full medical underwriting depends on your priorities.
You may prefer moratorium underwriting if you want:
- A faster application process
- Fewer medical questions
- Simplicity when arranging cover
You may prefer full medical underwriting if you want:
- Clear information about exclusions
- Greater certainty before making claims
- A detailed understanding of your cover
Reviewing your options carefully can help you choose the right balance between convenience and certainty.
Already Insured? Get Advice Before You Switch
Understanding how your medical history affects your cover depends heavily on whether you’re buying health insurance for the first time or switching policies:
- New to private medical insurance? You’ll generally choose between Moratorium (Mori) and Full Medical Underwriting (FMU) to set up your cover.
- Already insured? You’ll usually switch via Continued Personal Medical Exclusions (CPME). This protects the underwriting you had on your previous policy, ensuring any conditions you’ve developed since taking it out remain covered (subject to eligibility).
- When would you re-underwrite? Where a policy is already in place, our preferred option at Morehealth is switching via CPME. However, we may consider a Moratorium or FMU policy if you have a clear medical history or it lowers your premium..
