What does private health insurance cover in the UK?
Private medical insurance pays for the diagnosis and treatment of new, short-term (acute) conditions in private hospitals — things the NHS would treat, but faster and in private facilities. It is not designed for long-term chronic illness or emergencies. Here is what is typically covered, what is excluded, and how the modules change the picture.
The essentials in 30 seconds
- Core cover: private medical insurance pays for acute conditions — in-patient and day-patient treatment, surgery, hospital stays, consultations and diagnostic scans.
- Often included: cancer cover is a headline feature on most comprehensive plans, and many policies bundle some outpatient diagnostics.
- Optional modules: full outpatient cover, mental-health, and optical & dental are usually add-ons you choose, not automatic.
- Typically excluded: chronic and long-term conditions, A&E and emergencies (these stay with the NHS), pre-existing conditions per underwriting, routine pregnancy and cosmetic treatment.
Typically covered vs typically excluded
| Typically covered | Typically excluded |
|---|---|
| Acute conditions — new, short-term illnesses and injuries that respond to treatment | Chronic & long-term conditions that need ongoing management (e.g. diabetes, asthma) |
| In-patient & day-patient treatment, including hospital stays | Accident & emergency and emergency care — these remain with the NHS |
| Surgery and surgeon, anaesthetist and theatre fees | Pre-existing conditions, subject to your underwriting terms |
| Diagnostics & scans — MRI, CT and similar investigations | Routine pregnancy and normal childbirth |
| Cancer cover — often included on comprehensive plans (diagnosis and treatment) | Cosmetic and elective aesthetic procedures |
| Outpatient consultations & tests — sometimes core, often a module | Self-inflicted injury, and treatment outside the policy terms |
| Mental health and optical & dental — usually available as optional modules | Experimental or unproven treatments not recognised by the insurer |

What core PMI actually pays for
At its heart, private medical insurance is acute-condition cover. An acute condition is a new illness or injury that is likely to respond quickly to treatment and return you to the health you were in before — a hernia, a torn cartilage, a cataract, a suspected cancer that needs investigation. The core of almost every plan funds:
- In-patient and day-patient treatment: when you are admitted to a private hospital, whether or not you stay overnight, including the bed, nursing and theatre costs.
- Surgery and specialist fees: the surgeon, anaesthetist and associated hospital charges for covered procedures.
- Diagnostics and scans: MRI, CT and other investigations needed to diagnose a covered condition.
- Cancer cover: on comprehensive plans this is a major feature, funding diagnosis, surgery, chemotherapy and radiotherapy — though the exact level varies, so check the wording.

Modules that change what you're covered for
Beyond the core, most insurers let you bolt on modules. These are where two plans at the same headline price can cover very different things, so they are worth understanding before you compare:
- Full outpatient cover: consultations, specialist appointments and tests where you are not admitted. Plans often include a limited outpatient allowance as standard and let you extend it.
- Mental-health cover: in-patient and outpatient psychiatric treatment, frequently capped by days or a monetary limit, and increasingly offered as a defined module.
- Optical and dental: routine eye tests, glasses and dental work — usually a cash-benefit style add-on rather than full treatment cover.
- Therapies and extras: physiotherapy, chiropractic and similar may sit inside outpatient cover or be a separate option depending on the insurer.
Because modules drive both cover and cost, the like-for-like comparison matters more than the price alone. The private health hub walks through how tiers and modules fit together.
How cover tiers differ
Insurers usually offer a ladder of tiers, from a lean core plan up to a comprehensive one. A budget or core tier tends to focus on in-patient and day-patient treatment with little or no routine outpatient cover, often paired with a six-week NHS-wait option to keep the premium down. A mid tier adds an outpatient allowance and broader diagnostics. A comprehensive tier brings fuller outpatient cover, stronger cancer cover, wider hospital lists and the option of mental-health, optical and dental modules.
The key point is that “private health insurance” is not one fixed thing — what you are covered for is defined by the tier and modules you choose and by your underwriting terms. Two people can both hold PMI and yet have very different protection. Always compare the policy wording and exclusions, not just the tier name, and check how pre-existing conditions are handled under moratorium or full medical underwriting.
