Private Medical Insurance (PMI) offers a fantastic way to gain peace of mind, access prompt medical care, and bypass potential NHS waiting lists. However, the language used by insurers can often feel like a puzzle. From "moratorium underwriting" to "out-patient limits," understanding these terms is the first step towards choosing a policy that truly meets your needs.
This guide breaks down 50 of the most common terms into plain, simple English. We'll explain what they mean, why they matter, and how they affect your private health cover.
This is the most crucial section. Grasping these fundamental concepts will prevent any misunderstandings about what your policy is designed for.
1. Private Medical Insurance (PMI) Also known as private health cover, PMI is an insurance policy that covers the costs of private medical treatment for specific, curable conditions. Its primary purpose is to complement the NHS, not replace it. It gives you more choice over when, where, and by whom you are treated.
2. Acute Condition This is the cornerstone of PMI. An acute condition is a disease, illness, or injury that is likely to respond quickly to treatment and lead to a full recovery. Think of things like joint replacements, cataract surgery, or treatment for hernias. PMI is designed exclusively to cover acute conditions that arise after you take out your policy.
3. Chronic Condition A chronic condition is an illness that is long-lasting or recurring. It cannot be cured, only managed. Examples include diabetes, asthma, arthritis, and high blood pressure. Standard UK private medical insurance does not cover the treatment of chronic conditions. Management of these conditions remains with the NHS.
4. Pre-existing Condition This refers to any ailment, illness, or injury you had symptoms of, received advice for, or were treated for before your policy start date. This is a critical exclusion. PMI does not cover pre-existing conditions. The way insurers handle this depends on your underwriting type (see "Moratorium" and "Full Medical Underwriting" below).
5. Exclusions These are specific conditions, treatments, or circumstances that your policy will not pay for. Besides pre-existing and chronic conditions, common exclusions include routine pregnancy, cosmetic surgery, A&E visits, and drug abuse. Always read your policy document carefully to understand the exclusions.
Every policy starts with a foundation and can be tailored with optional extras.
6. Core Cover This is the basic level of cover included in every PMI policy. It almost always includes costs for in-patient and day-patient treatment, which covers surgery, hospital stays, nursing care, and specialist fees when you're admitted to a hospital bed.
7. In-patient You are an in-patient if you are admitted to a hospital and stay overnight for treatment.
8. Day-patient You are a day-patient if you are admitted to a hospital for a procedure but do not need to stay overnight. This is common for minor surgeries like arthroscopy.
9. Out-patient This refers to any treatment or consultation where you are not formally admitted to a hospital bed. This includes specialist consultations, diagnostic tests, and therapies. Out-patient cover is usually an optional extra or is included in more comprehensive plans. Limiting your out-patient cover is a common way to reduce your premium.
10. Add-ons / Optional Extras These are additional benefits you can add to your core cover for an extra cost. Common add-ons include:
11. Comprehensive Cover This is the highest level of cover available, typically including core cover plus extensive out-patient benefits, therapies, and often mental health support. It offers the most complete protection but comes with the highest premium.
12. Hospital List / Hospital Network Insurers have agreements with a network of private hospitals. Your policy will include a specific "hospital list" which dictates where you can receive treatment. A more extensive list, including premium central London hospitals, will increase your premium. Choosing a more restricted local list can be a great way to save money.
13. Guided Option / Guided Consultant List Some policies offer a "guided" route. Instead of choosing any consultant you wish, the insurer provides a shortlist of 3-5 pre-approved specialists for your condition. This helps the insurer manage costs, and in return, you receive a lower premium.
14. Mental Health Cover A crucial add-on for many. This provides cover for consultations with psychiatrists and psychologists, as well as in-patient or day-patient psychiatric treatment. The level of cover can vary significantly, from a set number of therapy sessions to more extensive residential care.
15. Therapies Cover Covers treatment from recognised practitioners like physiotherapists, osteopaths, and chiropractors. This is often essential for recovery from surgery or musculoskeletal injuries.
Understanding the financial elements of your policy is key to finding affordable cover.
16. Premium This is the regular amount you pay for your health insurance policy, either monthly or annually. Your premium is calculated based on your age, location, level of cover, excess, and medical history (if using Full Medical Underwriting).
17. Excess This is a fixed amount you agree to pay towards the cost of your treatment each policy year (or sometimes per claim). For example, if you have a £250 excess and your treatment costs £3,000, you pay the first £250 and your insurer pays the remaining £2,750. A higher excess leads to a lower premium.
| Treatment Cost | Your Excess | You Pay | Insurer Pays |
|---|---|---|---|
| £4,000 | £500 | £500 | £3,500 |
| £1,500 | £100 | £100 | £1,400 |
| £250 | £250 | £250 | £0 |
18. No Claims Discount (NCD) Similar to car insurance, many PMI providers offer a discount on your renewal premium for every year you don't make a claim. The NCD scale typically ranges from 0% to as high as 75%. Making a claim will usually reduce your NCD level at renewal.
19. Six-week Option This is a cost-saving option where your insurer will only pay for your treatment if the NHS waiting list for that procedure is longer than six weeks. If the NHS can treat you within six weeks, you will be treated by the NHS. This can significantly reduce your premium because it reduces the likelihood of a claim.
20. Co-payment A less common feature where you agree to pay a percentage of each claim, often in addition to your excess. For example, you might pay a £250 excess and then 10% of the remaining claim cost, up to a certain limit. This also lowers your premium.
21. Insurance Premium Tax (IPT) A tax charged on all general insurance premiums in the UK, including PMI. The standard rate is currently 12%, and this is automatically included in the premium you are quoted.
22. Self-insure This is the alternative to having insurance, where you choose to pay for any private medical treatment out of your own pocket. This can be extremely expensive; for example, a hip replacement can cost upwards of £13,000 privately.
Here’s a step-by-step look at the terms you'll encounter when you need to make a claim.
23. GP Referral In most cases, your journey to private treatment starts with your NHS GP. You visit your GP, who assesses your symptoms and provides a referral letter to a private specialist if needed. This referral is what you use to start your claim with the insurer.
24. Open Referral Some insurers and GPs operate on an "open referral" basis. This means your GP refers you for a type of specialism (e.g., "a cardiologist") rather than naming a specific consultant. Your insurer will then guide you to an appropriate specialist from their approved network.
25. Virtual GP / Digital GP A growing number of PMI providers now include access to a 24/7 virtual GP service. This allows you to have a video or phone consultation with a GP at your convenience, often with the ability to get prescriptions or open referrals quickly.
26. Claim This is the formal request you make to your insurer to cover the cost of your treatment. The process usually involves contacting your insurer's claims line with your GP referral details before any appointments or treatment take place.
27. Diagnostics / Diagnostic Tests These are tests used to identify a medical condition, such as MRI scans, CT scans, X-rays, and blood tests. Cover for diagnostics is usually part of out-patient cover.
28. Specialist / Consultant A senior doctor who has expert knowledge in a particular area of medicine (e.g., a cardiologist for heart conditions, or an orthopaedic surgeon for joint problems). Your PMI covers the fees charged by these consultants.
29. Eligible Treatment Any medical procedure, test, or consultation that is covered under the terms and conditions of your policy. Your insurer must pre-authorise treatment to confirm it is eligible before you proceed.
30. NHS Cash Benefit An optional benefit that pays you a fixed amount of cash for every night you choose to use the NHS for in-patient treatment, even though you have private cover. It’s a way to get some value from your policy without claiming for private care.
The method of underwriting determines how an insurer assesses your medical history and applies exclusions for pre-existing conditions. This is a critical choice you make when you first buy a policy.
31. Underwriting This is the process an insurer uses to evaluate risk and decide whether to offer you cover and at what price. For PMI, it's primarily about how they handle your past medical history.
32. Full Medical Underwriting (FMU) With FMU, you provide a full declaration of your medical history by completing a detailed questionnaire when you apply. The insurer assesses this information and may explicitly exclude certain conditions from your policy from day one. It provides clarity but requires more initial paperwork.
33. Moratorium Underwriting This is the most common type of underwriting. You don't have to declare your full medical history upfront. Instead, the insurer automatically excludes any condition you've had symptoms of, or received treatment for, in the 5 years prior to your policy start date. However, if you then go a continuous 2-year period after your policy starts without any treatment, advice, or symptoms for that condition, it may become eligible for cover.
34. Medical History Disregarded (MHD) This is a premium type of underwriting, usually only available for larger company schemes. As the name suggests, the insurer agrees to disregard your prior medical history and will cover pre-existing conditions (though chronic conditions are still typically excluded).
Here's a simple comparison of the main underwriting types:
| Feature | Full Medical Underwriting (FMU) | Moratorium Underwriting |
|---|---|---|
| Application Process | Long questionnaire about your medical history. | No medical questions upfront. Quick and simple. |
| Exclusions | Pre-existing conditions are clearly listed as exclusions on your policy documents from the start. | Blanket exclusion on conditions from the past 5 years. Can be unclear what is/isn't covered initially. |
| Claim Process | Generally faster, as the insurer already knows your history. | Can be slower, as the insurer may need to investigate your medical history at the point of a claim. |
| Best For | People who want absolute certainty about what is covered from day one. | People who haven't had any significant medical issues in the last 5 years and want a quick application. |
35. Policyholder The person who owns the insurance policy and is responsible for paying the premiums.
36. Dependant A person who is covered by the policyholder's insurance, typically a partner or children.
37. Cooling-off Period A legally required period, usually 14 days after you purchase the policy, during which you can cancel it and receive a full refund, provided you haven't made a claim.
38. Renewal At the end of your policy term (usually one year), your insurer will invite you to renew your cover for another year. They will provide a new premium based on your age, claims history (NCD), and medical inflation.
39. Annual Limit / Benefit Limit The maximum amount your insurer will pay out for eligible claims in a policy year. Some policies have limits on certain benefits (e.g., £1,000 for out-patient cover), while others offer an overall annual limit (e.g., £1 million). Many comprehensive policies now offer unlimited cover.
40. Grace Period A short period after your premium due date during which your policy remains active even if you haven't paid. If you don't pay by the end of the grace period, your policy will be cancelled.

48. Health Screening A set of tests and examinations designed to detect potential health problems at an early stage. Some high-end PMI policies include a health screen as a benefit.
49. Community Rated Scheme A type of pricing for large corporate schemes where everyone in the company pays the same premium, regardless of their individual age or claims history.
50. Policy Document The legal contract between you and your insurer. It details all the terms, conditions, benefits, and exclusions of your cover. It's essential to read this document carefully.
