Health Insurance Claim Denied in Tunisia? How to Appeal with the CGA

Tunisia's insurance sector is regulated by the Comité Général des Assurances (CGA) — the General Insurance Committee — operating under the authority of the Ministry of Finance. The CGA is responsible for licensing insurance companies, supervising their financial soundness, and protecting policyholders through its consumer complaint mechanisms. If your health insurer in Tunisia has denied a claim, the CGA is your primary external recourse.

Tunisia's Health Insurance Framework

Tunisia has a two-tier health coverage system:

Public / social insurance:

• CNAM (Caisse Nationale d'Assurance Maladie): Tunisia's national health insurance fund, established under Law No. 2004-71. CNAM covers employees in the formal private sector (via contributions through CNSS) and public servants (via specific funds). CNAM policyholders can access care through:
  • Public hospitals and clinics (free or heavily subsidised)
  • The CNAM contracted private network at agreed rates
  • "Filière libre" (free choice) — access to any private provider with partial CNAM reimbursement

Private insurance:

• Commercial health insurance (assurance complémentaire) is widely used to cover the gap between CNAM reimbursements and actual costs, especially for private hospital care, specialist fees, dental, and optical
• Key private insurers include Star (Société Tunisienne d'Assurances et de Réassurances) — the state-owned market leader, GIG Maghreb, ASTREE Assurance, Assurances BIAT, Carte Assurance, and Maghrebia Assurance

Common Denial Reasons in Tunisia

• CNAM not claimed first: most complementary policies require prior CNAM claim submission; denying the residual claim if this step is skipped
• Out-of-network treatment: the provider is not in the insurer's agreed network under the "filière organisée"
• Benefit not covered: the treatment (dental, optical, cosmetic, IVF) is outside the policy schedule
• Medical necessity not established: the insurer disputes clinical necessity
• Claim submitted late: reimbursement claims typically must be submitted within 60 to 90 days of treatment
• Pre-existing condition exclusion: conditions pre-dating the policy start date may be excluded for the waiting period

Step 1: Claim CNAM First (If Applicable)

If you are a CNAM member (fonctionnaire or private sector employee registered with CNSS), submit your invoices to CNAM first to receive the statutory reimbursement. Obtain the CNAM liquidation (settlement statement) showing what CNAM paid and the residual balance. Then submit the residual to your private complementary insurer.

Step 2: Request the Denial in Writing

Ask your insurer for a formal denial letter (refus de prise en charge or lettre de rejet) specifying the policy clause and reason for denial. This is your essential starting document.

Step 3: File an Internal Complaint with Your Insurer

Submit a written complaint (réclamation) to your insurer's service client or direction des sinistres. Include:

• Your policy number and CIN (Carte d'Identité Nationale) or passport number
• The denial letter and claim reference number
• CNAM liquidation statement if applicable
• Your treating physician's medical report (rapport médical)
• All invoices, receipts, and diagnostic reports
• Pre-authorisation correspondence if relevant

Give the insurer 15 to 20 working days to respond in writing. If no response or an unsatisfactory one is received, proceed to the CGA.

Step 4: Escalate to the CGA

File a complaint with the Comité Général des Assurances (CGA):

• In person: CGA offices, Rue Hédi Nouira, Tunis (near the Ministry of Finance)
• Phone: +216 71 120 000 (CGA main line)
• Email: cga@finances.gov.tn
• Postal: Comité Général des Assurances, Ministry of Finance, Tunis

Prepare a written complaint letter in French or Arabic describing:

• Your policy details and the insurer's name
• The nature and date of the claim
• The denial and the insurer's stated reason
• The outcome of your internal complaint
• The remedy you seek

Attach all supporting documents. The CGA will acknowledge your complaint, contact the insurer, and review the dispute. The CGA has supervisory authority over all licensed Tunisian insurers and can impose sanctions for non-compliance.

CGA Timelines

• Acknowledgement: typically within 7 to 10 working days
• Insurer response: requested within 30 days
• CGA determination: 30 to 60 days for standard complaints

Step 5: Tunisian Courts

For disputes not resolved through the CGA or involving bad-faith conduct:

• Tribunal de Première Instance: handles civil insurance contract disputes at first instance
• Tribunal de Commerce: for commercial-scale disputes
• The CGA's findings can be submitted as administrative evidence in court proceedings

Expat and Non-Resident Considerations

Tunisia has a relatively modest expatriate population, but receives significant medical tourism, particularly from other North African countries:

• Foreign residents employed in Tunisia — if registered with the CNSS, you are entitled to CNAM coverage on the same basis as Tunisian nationals
• Non-resident foreigners receiving treatment in Tunisia — typically covered by travel or international health insurance. Disputes go through your home insurer or policy-issuing country regulator.
• Tunisian diaspora (MRE) receiving treatment in Tunisia — your Tunisian policy (if you hold one) is governed by Tunisian law and the CGA process applies
• Language: The CGA process is conducted in French and Arabic. English submissions are accepted but may slow processing.

Fight Back With ClaimBack

Tunisia's CGA provides a structured route to challenge insurance denials. A well-prepared complaint with clear medical documentation and a proper paper trail gives you the strongest possible case. ClaimBack helps you put this together.
