Most mid-level and comprehensive policies cover MRI, CT, ultrasound and other diagnostics in full — but scans are usually classed as outpatient care, so a basic policy with no outpatient cover typically pays for no scans at all. Privately, diagnostics happen within days; on the NHS, roughly 1 in 4 patients wait over 6 weeks for tests.

The short answer: yes, if your policy has outpatient cover
Scans sit at the heart of what private health insurance is for: fast answers. On most mid-level and comprehensive policies, MRI, CT, ultrasound and X-ray are covered — usually in full at an approved facility, once a GP or consultant refers you and the insurer authorises it.
But there's a structural catch. Diagnostics are almost always classed as outpatient treatment, because you're not admitted to a hospital bed. That means your scan cover is determined not by some dedicated "scans" benefit, but by your policy's outpatient cover level — full, capped, or absent.
This surprises people because scans feel like a core hospital service. But from an insurance perspective, a 30-minute MRI appointment is the same category as a consultant chat or a physio session: care without admission. Understanding that one classification explains most of what follows on this page.
How the outpatient limit actually works
Outpatient cover typically comes in three flavours, and each treats your scans differently:
- Full outpatient cover. Consultations, scans and tests covered without an annual cap. Scans are simply authorised and paid.
- Capped outpatient cover. A monetary limit — commonly £500 to £1,500 a year — shared across consultations, scans and tests. One MRI plus a couple of consultations can exhaust a £500 limit.
- No outpatient cover. Inpatient-only policies. Diagnostics generally aren't covered unless they happen as part of an admission.
Some insurers soften this with carve-outs — for example, covering major diagnostics such as MRI, CT and PET in full even on plans with capped outpatient benefit, or covering diagnostics once cancer is suspected. These carve-outs vary by insurer and plan, which is exactly the sort of detail worth comparing before you buy rather than at claim time.
Why speed matters: NHS diagnostic waits
The NHS is brilliant. The waiting isn't — and diagnostics are where waiting bites first, because nothing else can happen until the scan does. NHS diagnostic figures (DM01) show roughly 1 in 4 patients waiting over 6 weeks for a diagnostic test (January 2026), against an NHS standard that almost nobody should wait that long.
Privately, the same scan typically happens within days, and usually inside 1–2 weeks — referral, authorisation, scan, report. For anything worrying, that's six weeks of not knowing versus a few days of finding out.
The diagnostic wait also compounds everything downstream. Treatment can't be planned until the scan is read, so a six-week diagnostic delay often becomes a six-week delay to everything else — the consultant's decision, the operation, the all-clear. That's why fast diagnostics are the single most-used benefit on most health insurance policies: far more people claim for a scan than for surgery in any given year.

What scans cost — covered vs self-pay
If you're insured with outpatient cover, you'll typically pay nothing beyond any policy excess. Without insurance, private diagnostics are still accessible — and cheaper than many expect:
| Test | Typical self-pay price | With insurance (outpatient cover) |
|---|---|---|
| MRI (one body part) | £300–£500 | Usually covered in full |
| CT scan | £350–£700 | Usually covered in full |
| Ultrasound | £150–£300 | Usually covered in full |
| X-ray | £80–£200 | Usually covered in full |
| Blood test panel | £50–£250 | Covered when part of investigation |
Prices vary by provider and region, with London generally at the top of each range. If you need one scan and have no insurance, self-pay is often the rational choice; if you want cover for whatever comes next — the consultant, the follow-up, the treatment — that's what insurance is for. See our private MRI guide for a fuller cost breakdown.
Remember that a scan is rarely the whole story: the consultant who orders it and the appointment that explains it each add £150–£250 self-pay, which is why an insured pathway often works out simpler even when the scan price alone looks manageable.
Direct access: scans without the usual referral chain
Traditionally the path is GP, then consultant, then scan. Some insurers now shorten it with direct access services: for certain symptoms — commonly musculoskeletal problems, and some cancer-worry pathways — you call the insurer first, a clinician triages you, and you can be sent straight for diagnostics without seeing a consultant beforehand.
It's worth knowing your insurer's route before you need it, because going outside the authorised pathway is the other common reason scan claims fail. The safe sequence is always: symptoms, referral or triage, authorisation from your insurer, then the scan at an approved facility.
- Call before you book. Pre-authorisation takes minutes and turns "should be covered" into "is covered".
- Use the approved network. Insurers pay in full at facilities on their list; going elsewhere can leave you with the bill.
- Keep the referral letter. It's the document that connects your symptoms to the scan — insurers ask for it.
- Know your excess. If you have one, the first scan of the year is usually where you'll pay it.
Get the sequence right and scan claims are among the smoothest in health insurance — authorised in a phone call, booked within days, and settled directly between the imaging centre and your insurer without a bill ever reaching you.
Frequently asked questions
Can I get a scan without a GP referral?
Sometimes. Several insurers offer direct-access pathways — commonly for musculoskeletal symptoms — where in-house clinical triage replaces the GP visit and can send you straight for diagnostics. Self-pay scan providers usually still require a referral, though many arrange one through an in-house clinician for a fee. Whatever the route, insurers still require authorisation before the scan for a claim to be paid.
What does the outpatient limit mean for my scans?
Everything. Scans are classed as outpatient care, so a policy with full outpatient cover pays for scans without an annual cap; a capped policy shares a limit — commonly £500–£1,500 — across consultations, scans and tests; and an inpatient-only policy generally pays for no scans at all. Some insurers carve out major scans like MRI and CT from the cap, so check your schedule.
Are blood tests covered by health insurance?
Generally yes, when a GP or consultant orders them to investigate symptoms and you have outpatient cover — they're treated like any other diagnostic and count towards any outpatient limit. Routine screening or general health-check bloods you request yourself typically aren't covered, since insurance pays for investigating symptoms rather than monitoring wellness. Some insurers offer discounted screening separately.
Can I choose where I have my scan?
Within limits. Your insurer authorises scans at facilities in your policy's approved network, which typically includes private hospitals and imaging centres near you — you can usually express a preference among them. Guided or restricted-list policies trade some choice for a lower premium. Self-pay, you can go anywhere, which is one genuine advantage of paying directly.
I have a basic inpatient-only policy — will it ever pay for a scan?
Occasionally, but don't rely on it. Diagnostics carried out while you're admitted as an inpatient or day patient are covered, and some basic plans include specific carve-outs — for instance once cancer is confirmed or under a cash-limited benefit. But the routine situation of a GP wanting an MRI for a bad knee generally isn't covered without outpatient benefit.
Do scans count towards my policy excess?
Yes, typically. The excess is the first part of any claim you pay in a policy year, and a scan is often the first cost in a claim — so a £250 excess may effectively come off your first scan or consultation. It's usually charged once per person per year (per claim on some policies), not per scan. Check which basis your policy uses.
Who reads my scan and how do results get back to me?
A consultant radiologist reports on the images, typically within a few days privately, and the report goes to the referring clinician — your consultant, GP or the insurer's triage service — who explains the findings and next steps. You can request a copy of both report and images, and imaging centres can share them with the NHS if your care continues there.
Are PET scans and specialist imaging covered?
Usually, on policies with appropriate cover — PET-CT is expensive (often £1,500–£2,500 self-pay) and most commonly needed in cancer diagnosis, where many insurers cover it under cancer benefit in full even when other outpatient cover is capped. Specialist cardiac MRI and similar tests follow the same logic: covered where clinically required and authorised, with cancer pathways often the best-protected.
How quickly will I get a scan after my referral?
Privately, typically within days — most insured patients have diagnostics completed within 1–2 weeks of referral, including authorisation and reporting, and simple scans are often available within 48 hours at imaging centres. That compares with roughly 1 in 4 NHS patients waiting over 6 weeks for diagnostic tests. Speed of answers is arguably insurance's single clearest benefit.
Does health insurance cover full-body MOT health screens?
Generally no. Health screening — checking a healthy person for hidden problems — is different from diagnosis, and insurance covers investigation of symptoms rather than screening. Many insurers offer discounted health assessments alongside their policies, and some plans include partial screening benefits, but a full-body MOT is normally a separate self-pay purchase, typically a few hundred pounds up.
