Sometimes, but authorisation was supposed to happen first, and going ahead without it is the usual reason a valid claim gets refused.

What the policy documents actually say

Insurers authorise before treatment, not after. AXA Health requires members to tell the place of treatment that they are a member, precisely so the fees charged are the ones it has agreed with that hospital. Pay privately without saying so and you may have been charged rates the insurer never agreed, which it will not reimburse in full even where the treatment itself was eligible.

There are exceptions worth pressing. Emergency treatment cannot be pre-authorised by definition — The Exeter's wording covers the transfer to private facilities once a consultant agrees you are stable and authorisation is in place. Bupa's Direct Access route also builds authorisation into the process, explaining how to claim after an assessment rather than requiring it beforehand.

If you have already paid, submit it anyway with the invoice, the referral and the clinical justification. A refusal on process grounds is more arguable than one on eligibility grounds, and insurers do pay retrospectively where the treatment was clearly covered and the failure was administrative.

What will not be rescued retrospectively is a treatment that was never eligible: a pre-existing condition, a chronic one, or a provider outside your list. Authorisation would have told you that before you spent the money, which is the actual value of asking first.

Keep everything. An invoice, a referral letter and a written note of any phone call are what an appeal runs on.

Questions to put to the insurer or broker

  • Will you consider a retrospective claim on this?
  • Was the treatment eligible in principle?
  • Were the fees within your schedule?

The limit behind every answer here

None of this reaches a condition you already have. Cover is written for problems that arise after it starts, so anything you have symptoms of when you apply is excluded — permanently under full medical underwriting, or until a symptom-free period has passed under a moratorium. Chronic conditions are excluded by every insurer whose wording we hold. Figures quoted come from current policy documents and change at renewal, so check the document you are actually offered.
