As an FCA-authorised expert broker that has helped arrange over 800,000 policies, WeCovr understands that navigating the world of private medical insurance in the UK can raise questions. One of the most common concerns we hear is about privacy: what happens to my confidential NHS data when I make a PMI claim? This guide demystifies the process, explaining exactly how your information is handled, what is shared, and what remains private.
The relationship between your private health cover and your NHS records is built on a foundation of strict data protection laws and medical ethics. Your insurer cannot simply access your entire medical history. Instead, a carefully controlled flow of specific information occurs only when you make a claim, and always with your explicit consent.
Think of it not as an open door, but as a series of secure checkpoints. At each stage, only the necessary information required to assess your claim is requested. As we move further into 2025, with the increasing digitisation of health records through platforms like the NHS App, you have more transparency and control than ever before. This article will walk you through that entire journey.
Before diving into data sharing, it's essential to understand what PMI is designed for. It's a key part of the UK's health landscape, working alongside, not against, the NHS.
Private Medical Insurance is an insurance policy that covers the cost of private healthcare for specific conditions. Its primary benefits include:
PMI is not a replacement for the NHS. You will still use the NHS for accidents and emergencies, GP visits, and the management of long-term chronic conditions.
This is the most important concept to grasp about private medical insurance in the UK.
Standard UK private health cover does not cover pre-existing or chronic conditions. This rule is fundamental to how insurers manage risk and keep premiums affordable. The data sharing process we are about to explore is primarily in place to help insurers verify that your claim is for a new, acute condition covered by your policy.
Let's trace the journey of your information from the moment you feel unwell to the completion of your private treatment.
Scenario: You have a persistent, painful knee that is affecting your quality of life. You have a PMI policy and want to use it.
Step 1: You Visit Your NHS GP Your journey almost always begins with the NHS. You visit your GP, who examines your knee. They agree you need to see a specialist but mention the local NHS waiting list for an orthopaedic consultant is several months long.
Step 2: You Get an 'Open Referral' You mention you have private medical insurance. Your GP provides you with an 'open referral' letter. This is a crucial document. It doesn't name a specific specialist; it simply confirms your symptoms and recommends you see a certain type of specialist (e.g., an orthopaedic consultant).
Step 3: You Contact Your PMI Provider You call your insurer's claims line (or use their app). You explain your symptoms and tell them your GP has recommended seeing a specialist.
Step 4: The Insurer Begins the Authorisation Process The insurer needs to check three things:
To do this, they need more medical information. They will ask for your consent to obtain it.
Step 5: How Your Insurer Gets Your Medical Records (With Your Consent) This is the key data-sharing step. You will be asked to sign a consent form (usually digitally) that allows your insurer to request specific information from your GP. This is governed by the Access to Medical Reports Act 1988 and GDPR.
| Information Typically Requested by Insurer | Information NOT Requested or Shared |
|---|---|
| Notes on symptoms related to the current claim. | Unrelated mental health consultations. |
| Dates of any previous consultations for the same body part. | Full history of childhood illnesses. |
| Any medication or advice given for this issue. | Sexual health records (unless relevant to the claim). |
| Referral letters and diagnostic test results. | Details of family members' health. |
Step 6: Authorisation and Treatment The insurer reviews the GP report. If it confirms your knee problem is a new issue that started after your policy began, they will authorise the claim. They will provide you with a list of approved specialists and hospitals from their network. You book your appointment, and the insurer settles the bills directly.
Step 7: Information Flow During and After Treatment The private specialist will keep their own records. They will need to share information with your insurer for billing purposes, including treatment codes and consultation dates. After your treatment (e.g., a knee arthroscopy), the specialist will write a discharge summary. A copy of this is sent to your NHS GP to ensure your NHS record is complete and up-to-date.
The entire process is underpinned by robust UK law. You are in control.
These laws set out the principles for handling personal data. For health information, the rules are even stricter because it is classed as 'special category data'. Key principles include:
Your insurer is legally bound by these principles. Breaches can result in massive fines from the Information Commissioner's Office (ICO).
Nothing happens without your permission. When you apply for PMI or make a claim, you give consent. However, this is not a blanket permission.
You have the right to refuse consent. However, if you do, the insurer will likely be unable to assess your claim and will have to decline it, as they cannot verify if the condition is eligible for cover.
Your GP acts as a trusted, independent gatekeeper of your medical history.
Your GP's role is to provide an objective, factual report based on your records. They are not acting for the insurance company; they are acting as the custodian of your medical file. Their duty of care is to you, the patient.
A GP can refuse if they believe sharing the information would cause serious harm to your physical or mental health. This is rare. More commonly, you, the patient, have the right to see the report before it is sent to the insurer. If you spot a factual inaccuracy, you can ask for it to be corrected. If you disagree with a medical opinion, you can ask for your own statement to be attached to the report.
Completing insurance reports is not part of a GP's core NHS work. Therefore, they are entitled to charge a fee for the time it takes to review your records and write the report. Your insurer will almost always cover this fee directly, so you shouldn't be out of pocket.
Let's look at a few examples to see how this plays out.
Scenario 1: Claim for Gallbladder Surgery
Scenario 2: Claim for Back Pain is Queried
Scenario 3: Claim for Mental Health Support
There's a lot of misinformation out there. Let's clear it up.
Myth 1: "My insurer can see my entire NHS history whenever they want." Fact: False. Insurers can only request specific information relevant to a claim, and only with your explicit consent for each claim. They do not have continuous, open access.
Myth 2: "Using PMI will negatively affect my future NHS care." Fact: False. The NHS principle of providing care based on clinical need is sacrosanct. The fact that you have used private insurance in the past has no bearing on your right to access NHS care in the future. In fact, by using PMI, you are helping to reduce the waiting list for others, which indirectly supports the NHS.
Myth 3: "My employer will see my sensitive medical details if I have a company PMI policy." Fact: Absolutely false. All claims and medical information are strictly confidential between you, your healthcare providers, and the insurer. Your employer only receives anonymised, aggregated data for scheme renewal purposes (e.g., "the scheme had 5 orthopaedic claims and 3 dermatology claims last year"). They will never know who claimed for what.
Understanding how data is shared helps you choose a policy with confidence. A specialist PMI broker can be invaluable here.
When you first apply, your policy will be "underwritten". This determines how the insurer treats pre-existing conditions.
An expert broker, like WeCovr, can explain the pros and cons of each and help you decide which is best for your circumstances.
Trying to compare the best PMI providers, their policies, and their claims philosophies can be overwhelming. A broker does the hard work for you.
