Pre-authorisation - sometimes called pre-approval, prior authorisation, or just pre-auth - is your insurer signing off on a treatment before it happens. If your policy requires pre-auth for something and you skip it, the insurer can refuse to pay even if the treatment is otherwise covered. That's where most of the "but it's covered, why won't they pay?" stories come from.
What typically needs pre-auth in the UAE
This varies by plan, but the usual list looks like:
- All inpatient admissions (planned)
- Major day-case procedures (endoscopies, MRIs, some imaging)
- Maternity-related procedures (delivery, C-section)
- Mental health admissions and some outpatient counselling
- Physiotherapy beyond a certain number of sessions
- Dental procedures over a cost threshold (when dental is covered at all)
- Specialised treatments (chronic disease management programs, fertility, etc.)
Routine GP visits, basic consultations, and small lab tests almost never require pre-auth - those are direct-billed at the desk.
How pre-auth actually works
The process is short, but the timing matters:
- Your doctor or the hospital initiates it. They send your insurer a request with the proposed treatment, diagnosis codes, and an estimated cost. You don't do this yourself - but you do need to know it's happening.
- The insurer reviews. Usually within 24–48 hours for non-emergency cases. They either approve, approve with conditions (cheaper alternative, second opinion required, etc.), or deny.
- The hospital books your appointment based on the response. If approved, the treatment proceeds and the insurer direct-bills the hospital. If denied, you can appeal or pay out-of-pocket.
Emergencies
Genuine emergencies (heart attack, accident, anything immediately life-threatening) don't require pre-auth - you go to the nearest hospital and the paperwork follows after. But "emergency" has a strict definition. Severe back pain you've had for three weeks is not an emergency, even if it feels urgent. Insurers will challenge the classification.
The most common ways people get stuck with the bill
Walking in without pre-auth for something planned
Most denials we see in the UAE come from someone booking an MRI, endoscopy, or scheduled procedure, going in, having it done, and only learning afterward that pre-auth was required. The hospital usually checks before booking - but not always, especially for diagnostic imaging.
Using an out-of-network provider
Pre-auth approval is for a specific treatment at a specific facility. If your pre-auth covers an MRI at Mediclinic and you do it at NMC instead, the approval doesn't carry over. Always confirm the facility on the pre-auth letter.
Pre-auth lapsing
Most pre-auths are valid for 30–90 days. If you delay the procedure past that window, the pre-auth expires and the insurer has to re-approve. The hospital should flag this, but check the expiry date yourself.
"Conditional" approvals
Sometimes the insurer approves the procedure but at a lower amount than the hospital wants to charge. The hospital can either accept that amount (you're covered as expected), or charge the difference to you. Ask the desk: "Is this fully covered at the approved amount?"
What to do if a claim gets denied for missing pre-auth
- Ask the insurer in writing why it was denied - they're required to provide a reason.
- If the treatment was genuinely urgent, document it (medical records, ambulance notification, ER admission notes) and submit an appeal.
- If the doctor or hospital was supposed to initiate pre-auth and didn't, ask them to file a retroactive request. This sometimes works, especially within 7–14 days of the treatment.
- If the insurer still refuses, you can escalate to the relevant regulator: DHA for Dubai, DOH for Abu Dhabi, MOHAP for the Northern Emirates.
How Covered helps with pre-auth
Upload your policy and ask "do I need pre-approval for an MRI?" - Covered finds the exact paragraph of your policy that lists pre-auth requirements and quotes it back to you. You get the answer in plain English plus the source text, so you can show the hospital or call your insurer with the right wording.
Most pre-auth issues are avoidable with a 30-second check before you book. That's exactly what Covered is for.
