Private Medical Insurance Explained: Cover, Costs, and Key Considerations
Private medical insurance is a type of cover designed to help pay for private healthcare when you need medical treatment.
It is often mentioned alongside the NHS, but it works in a different way and serves a specific purpose.
For many people, the idea of private medical insurance raises questions about what is included, what is excluded, and how it fits with existing healthcare services.
Policies can look similar at first glance, yet the detail can vary in ways that affect how the cover works in practice.
Understanding the basics of private medical insurance makes it easier to see whether it suits your needs, your budget, and your expectations around access to care.
How It Works
Private medical insurance, sometimes called PMI, is a type of protection that helps pay for private medical treatment if you become ill or injured during the policy term.
It works alongside the NHS rather than replacing it. You still use the NHS for emergency care and many routine services. Private medical insurance is mainly used for planned treatment, diagnosis, and consultations for conditions that are considered acute.
Acute conditions are those that are short term and treatable, with the aim of making you better. Most policies focus on this type of care.
You pay a premium, either monthly or annually. If you need treatment that your policy covers, the insurer pays the eligible costs, subject to the terms of the policy and any excess you have chosen.
What private medical insurance usually covers
The exact cover depends on the insurer and the policy level. That said, most policies include similar core elements.
Inpatient and day patient treatment
This is the foundation of most private medical insurance policies.
Inpatient treatment refers to care that requires an overnight stay in hospital. Day patient treatment covers procedures where you are admitted and discharged on the same day.
This part of the policy often includes:
- Consultant fees related to covered treatment
- Hospital accommodation and nursing care
- Surgery and related procedures
- Tests carried out during admission
Entry level policies may focus mainly on this area of cover.
Outpatient consultations and tests
Outpatient care covers appointments and tests where you do not stay in hospital overnight.
Some policies include outpatient cover as standard. Others apply limits, such as an annual cap. Some require it to be added as an extra.
Outpatient cover may include:
- Specialist consultations
- Diagnostic tests and scans
- Follow up appointments related to an acute condition
The level of outpatient cover can make a noticeable difference to how quickly you access diagnosis.
Cancer cover
Cancer cover is included in most modern private medical insurance policies, but the scope can vary.
Many policies cover:
- Specialist consultations
- Diagnostic scans
- Surgery
- Radiotherapy and chemotherapy
Some policies also cover certain drugs that are not routinely available through the NHS. Limits may apply, so it is important to check how each insurer defines cancer treatment and follow up care.
Mental health treatment
Mental health cover is available on many policies, but it is usually limited.
Depending on the policy, cover may include:
- A set number of outpatient therapy sessions
- Inpatient psychiatric treatment with time limits
- Specialist consultations
Long term or open ended therapy is not usually included. The policy wording matters in this area, so it is worth reviewing carefully.
Therapies such as physiotherapy
Physiotherapy and similar therapies are often included, but usually with limits.
Policies may specify:
- A maximum number of sessions
- A financial cap per year
- A requirement for referral from a consultant
This type of cover is commonly used for muscle and joint conditions.

What private medical insurance usually does not cover
Understanding exclusions is just as important as understanding what is included.
Pre existing conditions
Most personal private medical insurance policies exclude pre existing conditions.
A pre existing condition can include symptoms, treatment, medication, or advice received before the policy started. Even a single GP visit can be relevant.
Some underwriting methods allow past conditions to become covered after a set period without symptoms, but this depends on the policy terms.
Chronic conditions
Chronic conditions are long term or ongoing conditions that are not considered curable.
Examples include diabetes, asthma, arthritis, and many autoimmune conditions. Policies may cover tests that lead to diagnosis, but ongoing management is usually excluded.
Emergency treatment
Private medical insurance does not cover emergency care.
Accidents, serious sudden illness, ambulance services, and A and E treatment remain the responsibility of the NHS.
Routine healthcare
Most policies do not cover:
- Routine GP appointments
- Prescriptions
- Standard dental and optical care
- Normal pregnancy and childbirth
Some insurers include digital GP services as an added benefit, but this is separate from full primary care.
How claims typically work
Although insurers differ, the claims process usually follows a similar structure.
- You speak to a GP about your symptoms
- The GP provides a referral to a specialist
- You contact your insurer for authorisation
- The insurer confirms what is covered
- You book treatment with an approved consultant or hospital
- The insurer pays the eligible costs, minus any excess
Most insurers require authorisation before treatment begins. Booking appointments without approval can lead to claims being declined.
Is private medical insurance essential
Private medical insurance is optional. Some people are comfortable relying entirely on the NHS. Others prefer to have access to private treatment for certain types of care.
It can be suitable if you want:
- Shorter waiting times for some non urgent treatments
- A choice of consultant or hospital
- Access to private facilities where available
- Quicker access to diagnostics and therapies
It may be less suitable if:
- Your budget is limited
- You already have comprehensive cover through work
- You are mainly concerned about long term conditions
- You expect wide cover for past medical issues
The value of a policy depends on how closely it matches what you want it to do.
What affects the cost of private medical insurance
There is no single price for private medical insurance. Premiums vary based on several factors.
Age
Premiums generally increase with age, as the likelihood of claims rises.
Location
The cost of private treatment varies by region, which affects premiums.
Level of cover
Broader cover usually costs more.
This includes:
- Higher outpatient limits
- Wider hospital choice
- Enhanced cancer or mental health cover
Excess
An excess is the amount you pay towards a claim.
Choosing a higher excess can reduce premiums, but you need to be comfortable paying it if you claim.
Underwriting method
How the insurer assesses your medical history affects both price and certainty.
Understanding underwriting options
Moratorium underwriting
This approach does not require full medical disclosure at application.
Conditions you have had in a set look back period are excluded initially. They may become covered later if you remain symptom free for a defined period.
It is often quicker to set up, but claims may take longer to assess.
Full medical underwriting
You complete a detailed medical questionnaire at the start.
The insurer confirms which conditions are covered and which are excluded. Claims are often simpler later because the history has already been reviewed.
Employer provided cover
Workplace schemes sometimes treat medical history differently.
If you have cover through work, it is worth checking what happens if you leave employment, and whether you can continue the policy.
Managing the cost without over insuring
Many people aim to balance affordability with useful cover.
Practical ways to do this include:
- Choosing cover that matches how you expect to use the policy
- Selecting a hospital list that includes nearby facilities
- Considering a higher excess if savings allow
- Reviewing optional extras carefully rather than adding everything
Conclusion
Private medical insurance provides access to private diagnosis and treatment for new, acute conditions. It can offer shorter waiting times and more choice for certain types of care.
It does not cover everything, and it is not designed to replace the NHS. Pre existing conditions, chronic care, and emergencies usually sit outside the scope of cover.
There are many different policies available, so finding one that is suitable to you is bespoke. As a result, taking professional advice is highly recommended. If you are considering private medical insurance, contact us today.
