Top 20 reasons UAE insurance pre-authorizations get rejected

WhyAdvanced imaging (MRI/CT/PET), surgery, day-case procedures, high-cost drugs, biologics and inpatient admissions almost always need pre-approval. Treat first and bill later and there is usually no recovery — a missing pre-auth is denied outright (Daman AUTH-001) however justified the care was.

AvoidKeep a payer-specific pre-auth list and confirm whether the exact CPT needs approval on that plan before you render it. Get the approval reference in writing, including for downstream orders (telemedicine-prescribed meds/DME, add-on items, bundle components).

WhyA service billed without a documented indication, or with a diagnosis that does not justify it under the coverage criteria, is denied (Daman MNEC-003/004). Classic triggers: imaging as screening with no signs or symptoms, obstetric ultrasound without a covered indication, pre-op labs on a low-risk case. "MRI brain please" with no duration, findings or red-flag screen fails automatically.

AvoidDocument a specific indication — signs, symptoms, or an established diagnosis — that maps to the service's criteria, and code that diagnosis on the claim. For imaging, state symptom duration, focal findings, red-flag status and any failed conservative trial.

WhyCover that was expired, cancelled, suspended, not yet effective, or billed to the wrong plan or TPA is rejected before any clinical review. UAE eligibility is keyed to the Emirates ID against the payer's live system, so any mismatch — including cover lapsing between chronic-care visits — trips the eligibility denials.

AvoidRun a real-time eligibility check (eClaimLink, Shafafiya/Riayati) on the Emirates ID before registration and again before high-cost services — confirm plan name, network tier, effective and expiry dates, and the correct payer/TPA. Re-verify every repeat and chronic visit.

WhyAn approval exists, but the CPT, site/laterality, quantity or encounter level actually billed differs from what was pre-certified — so it is denied even though "we had an approval" (Daman AUTH-005). Common when the intra-operative situation changed, the case escalated to inpatient, or components were added.

AvoidReconcile the final billed codes, quantity and site against the approval before you submit. If the clinical picture changed, obtain an amended or new authorization rather than assuming the original covers it.

Daman MRI/CT Spine & Pre/Post-Op Labs (AUTH-005); DOH V2025.1 §4.5.

WhyDaman guidelines require ICD and CPT coded to the highest level of specificity. A truncated or "unspecified" code fails to establish site, severity and necessity and drives a coding or medical-necessity denial — vague codes read as insufficient justification.

AvoidAssign the most specific ICD-10 and CPT the note supports — laterality, site, degree or extent, gestational age, acuity — and avoid "unspecified" when a more specific code exists.

WhyA clinically valid request is still denied when the item is excluded from that plan tier — Basic plans exclude many devices and biologics, Visitor plans cover emergencies only, and maternity, IVF, obesity and refractive surgery are benefit-gated. A LASIK request that meets refraction criteria is still denied as a policy exclusion on a Basic plan.

AvoidCheck the service against the member's exact Schedule of Benefits — plan type, drug list, riders, limits — before delivering. For non-covered items, advise self-pay rather than submitting.

DOH V2025.1 §4.4.1; Daman Renal Haemodialysis, PCSK9, Hep C, OB Ultrasounds (NCOV-001/003, BENX-002). Exact tier exclusions vary by policy year.

WhyRepeating a test before its minimum interval or above the allowed frequency is denied (Daman MNEC-005). Typical caps: no repeat MRI/CT spine for the same condition within 180 days, and a maximum of three obstetric ultrasounds per pregnancy. Several payers also cap chronic-disease lab frequency (e.g. HbA1c, vitamin-D testing) under their own policies.

AvoidCheck when the same test was last done; if repeating inside the interval, attach the prior report plus documented new or progressive symptoms, and use the correct repeat indicator (R1/R2 radiology, L1/L2 lab) where required. Don't re-run to re-confirm a normal result.

WhyAdvanced imaging, surgery and biologics are denied when a required prior step was skipped, or the prior trial is mentioned without drug name, dose, duration and reason for failure. Examples: MRI spine with no physiotherapy trial, degenerative-meniscus surgery before an adequate conservative-care trial, a biologic before a conventional-DMARD failure.

AvoidDocument every prior treatment with drug name, dose, duration and the specific reason for failure before requesting the next-line intervention. Confirm the exact required trial durations against your payer's current criteria.

WhyMany services are restricted to named specialties; a claim from an ineligible clinician is denied for specialty mismatch (Daman CODE-010 / CLN-001). Gates include PCSK9 inhibitors (Cardiology, Endocrinology or Internal Medicine), Hepatitis C therapy (GI, hepatology or ID), and Thiqa elective MRI/CT spine (Specialist or Consultant only).

AvoidConfirm the ordering and performing clinician's licensed specialty is on the service's eligible list before billing, record both clinician IDs, and route specialty-gated drugs and imaging to an eligible specialist.

WhyThin, generic notes — "patient stable, vitals normal" — leave the payer unable to verify the service was warranted, so it is denied. Vague onset ("a few months ago") and inconsistent dates compound it.

AvoidWrite notes that state the diagnosis, the clinical reasoning and exactly what was done, so the documentation stands alone. Use clear, consistent dates and review completeness before coding.

DHA Claims Management Policy Directive PD-05-2025; UAE RCM guidance.

WhyMany services are covered only with specific attachments, and their absence is an outright rejection. Examples: haemodialysis needs clinical history and indication, Hepatitis C therapy needs baseline HCV RNA and genotyping, anti-VEGF injections need the intravitreal pre-requisite form, and high-cost items need an invoice with manufacturer, product and price.

AvoidBuild a per-service attachment checklist keyed to the guideline and attach the mandated items at submission — clinical history, baseline labs, prior imaging reports, item invoices and required forms.

WhyA drug outside the plan's covered formulary — not on the Basic drug list, a brand where only generic is covered, or absent from the DHA/MOHAP or DOH drug list — is not payable (NCOV family). Generic substitution can also down-substitute a brand claim unless "brand necessary" is documented.

AvoidVerify the drug against the plan's formulary and the authority drug list before dispensing; substitute a covered or generic alternative where allowed, write "brand necessary" when substitution must be blocked, or use the formulary-exception process.

WhyA covered medication is still rejected when it is subject to prior authorization, step therapy, or quantity and supply limits — common for chronic and high-cost drugs and biologics. Dispensing without the approval, above the allowed quantity, or for an indication or age that does not meet the criteria (e.g. evolocumab below its paediatric age floor) is denied.

AvoidBefore dispensing, check whether the drug needs prior approval or has quantity, step or age limits on that plan; obtain approval, match the exact covered indication and severity threshold, and stay within the allowed quantity and duration.

Daman PCSK9 (age floors) & Schedule of Benefits; UAE pharmacy-rejection guidance. Severity/age thresholds vary by drug.

WhyAn evaluation (E&M) billed the same day as a procedure is only separately payable if it is a distinct, separately identifiable service beyond the routine pre- and post-procedure work — appended with Modifier 25 and documentation that says so. Modifier 25 without that supporting documentation is denied.

AvoidOnly bill same-day E&M when it addresses a separate problem or separate decision-making; append Modifier 25 and document explicitly that the evaluation was separately identifiable, beyond routine pre/post-procedure care.

DOH Claims & Adjudication Rules V2025.1 §5.4.1.

WhyBilling a component already included in a parent code or bundle is denied (Daman PRCE-002/010). A surgical CPT already includes local anaesthesia, same-day pre-op evaluation and typical follow-up; wound cleansing and dressings bundle into the E&M; and a "without then with contrast" scan uses the single combined CPT.

AvoidDon't itemize services the code already includes; report bundled activities at zero charge where DOH requires; use combined or composite CPTs where they exist; keep the code library current with bundling rules.

DOH V2025.1 §4.2; Daman Wound Care, MRI/CT Spine (PRCE-002/010).

WhyThe same service submitted twice — a system re-send, a resubmission before the first adjudicated, or the same imaging repeated for the same condition within 180 days with no new indication — is rejected as a duplicate (Daman DUPL-002). DOH also requires all same-day, same-physician outpatient services on one claim.

AvoidCheck submission and remittance history before resending; wait for the original remittance and mark resubmissions as corrected; consolidate same-day, same-physician outpatient services into one claim; document a new indication before repeating imaging.

DOH V2025.1 §4.1, §4.4; Daman Wound Care (DUPL-002).

WhyThe procedure is paired with an ICD-10 that does not clinically justify it, or the code contradicts the report ("MRI with contrast" billed when the report says without), or an outdated code is used. UAE payers require documentation to connect condition to treatment; a mismatch reads as not medically necessary and can flag you for coding audits.

AvoidValidate every procedure–diagnosis pairing and match codes exactly to the report using current ICD-10 and CPT sets; use certified coders and run pre-submission scrubbing to catch contradictory or default codes.

WhyClaims filed after the contractual window generally cannot be recovered — the payment right expires. Dubai's PD-05-2025 directive sets settlement and resubmission timelines and adds a delay fee (0.03% per day). The same applies when a TPA pends a claim for documents and you reply after the deadline.

AvoidSubmit promptly rather than in batches; monitor days-since-service and prioritize claims nearing the deadline; track payer queries daily with clear ownership so documents go back within the stated window.

WhyA misspelled name, invalid or mismatched Emirates ID, wrong member or policy number, or wrong date of birth is rejected before clinical review, because UAE payer systems are keyed to the Emirates ID. Even a minor front-desk keying error can auto-reject.

AvoidCapture demographics directly from the Emirates ID and the eligibility response rather than patient dictation; validate ID and member-number format at registration; confirm details before the claim is created.

WhyIndication-locked tests are denied when used as general screening in asymptomatic patients — tumour-marker panels, upper GI endoscopy without alarm features, or PET before conventional CT/MRI is inconclusive. Billing a day-case as inpatient without documented escalation criteria is re-leveled or denied.

AvoidOrder indication-locked tests only for their named indication with supporting findings; complete and document inconclusive conventional imaging before PET; bill the setting the documentation supports.
