Private Medical Insurance: What It Covers and How to Choose

What is private medical insurance?

Private medical insurance is a policy that covers some or all of the cost of private healthcare, typically for the diagnosis and treatment of acute conditions — illnesses or injuries that can be cured, usually within a relatively short period of time. It allows policyholders to access private hospitals, consultants and diagnostic tests, often with shorter waiting times than might otherwise be available.

PMI works alongside, rather than instead of, the NHS. Many policyholders use the NHS for GP appointments, emergency care and ongoing chronic condition management, while using private cover for elective treatments, specialist consultations, or diagnostic tests where private access can offer more choice or speed.

What's typically covered

Most private medical insurance policies cover inpatient and day-patient treatment for acute conditions, meaning hospital stays and procedures. Many policies also include outpatient cover, such as consultations with specialists, diagnostic tests like MRI or CT scans, and physiotherapy, though the extent of outpatient cover often varies between different levels of policy and can be subject to annual limits.

Additional benefits available on some policies include cancer cover with access to specific treatments and drugs, mental health support, and cover for complementary therapies. Policies are usually tiered, with basic plans covering core hospital treatment and more comprehensive plans extending to a wider range of outpatient care and additional benefits, so it's worth comparing what's included at each level rather than assuming all PMI policies are the same.

• Inpatient and day-patient treatment for acute conditions
• Outpatient consultations and diagnostic tests (often with limits)
• Optional extras such as cancer cover, mental health support, or therapies
• Access to private hospitals and choice of consultant, subject to policy terms

What's typically excluded

Private medical insurance generally doesn't cover chronic or long-term conditions that cannot be cured, such as ongoing management of diabetes or long-term back pain, though it may cover acute flare-ups in some cases depending on the policy. Pre-existing medical conditions are also commonly excluded or subject to specific underwriting terms, meaning cover for a condition you had before taking out the policy may be limited or excluded.

Other common exclusions include normal pregnancy and childbirth, cosmetic treatment, A&E and emergency ambulance services (which remain the role of the NHS), and organ transplants, although some of these may be available as optional add-ons on certain policies. It's important to read the policy document carefully, as exclusions and the treatment of pre-existing conditions vary considerably between insurers.

What affects the cost

Premiums for private medical insurance are influenced by factors such as your age, where you live, the level of cover chosen, and whether you select options like a higher excess or restrictions on the hospital network available, both of which can reduce the premium. Pre-existing medical conditions and your overall health history are also taken into account during underwriting.

Employer-provided PMI is common as a workplace benefit, and some people top up employer cover with their own policy for additional benefits. For individual policies, choosing a plan with moderate excess, a defined hospital list, or restricted outpatient cover can help manage cost, though it's worth balancing this against how much flexibility you actually want if you need to make a claim.

Tips for choosing a policy

Think carefully about what matters most to you: wider hospital choice, comprehensive outpatient cover, or a lower premium with more restrictions. Check how the insurer treats pre-existing conditions, as this can significantly affect whether a policy is suitable for your circumstances, and ask about moratorium versus full medical underwriting approaches, as these affect how pre-existing conditions are assessed.

It's also worth checking claim limits, any no-claims discount structures, and whether the policy includes access to a GP helpline or similar support services.

Frequently asked questions

Does private medical insurance replace the NHS?

No, it works alongside the NHS rather than replacing it; most policyholders still use the NHS for GP care, emergencies and ongoing chronic condition management.

Are pre-existing conditions covered by PMI?

This depends on the insurer and underwriting approach; pre-existing conditions are often excluded or subject to specific terms, so it's important to check how a policy treats your medical history before buying.

Does PMI cover chronic conditions?

Generally no, as PMI is typically designed for acute, curable conditions rather than ongoing management of chronic or long-term illnesses, though this varies by policy.

Is maternity care covered under private medical insurance?

Normal pregnancy and childbirth are usually excluded from standard PMI policies, although some insurers offer optional maternity cover as an add-on.

Can I get private medical insurance through my employer?

Yes, many employers offer PMI as a workplace benefit, and some employees choose to top this up with additional personal cover for extra benefits not included in the employer scheme.
