Health Insurance Claim Denied in India: IRDAI Grievance Process Guide

India's health insurance market has grown dramatically, but so have claim disputes. Understanding common denial reasons is essential to building a successful appeal — and India's multi-layered regulatory framework gives policyholders a well-defined escalation path.

Why Insurers Deny Claims in India

Indian policyholders have strong regulatory protections under the Insurance Act, 1938 (as amended) and IRDAI regulations. Section 45 provides the foundational indisputability clause: after three years from the date of policy issuance, the insurer cannot challenge the policy on grounds of misrepresentation or non-disclosure, except in cases of fraud. The IRDAI (Protection of Policyholders' Interests) Regulations, 2017 requires insurers to process claims within 30 days of receiving all necessary documents, pay interest on delayed settlements, and provide clear written reasons for claim denials. The 8-year moratorium clause prohibits denial on non-disclosure grounds after 8 years of continuous health coverage (except fraud).

Common denial grounds include: pre-existing condition (PED) exclusions where insurers claim conditions existed before policy purchase (IRDAI has standardized PED waiting periods — typically 2–4 years — and after the waiting period expires, PEDs must be covered); waiting period violations for disease-specific conditions; non-disclosure of medical history within the first 3 years; treatment at a non-network hospital or excluded services (cosmetic, dental, alternative medicine); documentation deficiencies (missing discharge summaries, investigation reports, bills); and room rent capping that proportionally reduces the entire claim.

How to Appeal

Step 1: File a written complaint with the insurer's GRO

Submit a formal written complaint to the insurer's Grievance Redressal Officer. Include your policy number, claim number, the specific denial reason, and why you believe the denial is incorrect. The insurer must respond within 15 working days under IRDAI regulations.

Step 2: Escalate to IRDAI through IGMS or Bima Bharosa

If the insurer's response is unsatisfactory or no response within 15 days, file a complaint on the IGMS portal at igms.irda.gov.in or Bima Bharosa at bimabharosa.irdai.gov.in, or call the Bima Bharosa helpline at 155255. IRDAI forwards to the insurer and monitors response; escalation can trigger penalties against non-compliant insurers.

Step 3: Approach the Bima Lokpal (Insurance Ombudsman)

File with the Insurance Ombudsman (Bima Lokpal) having jurisdiction over your area at cioins.co.in. The Ombudsman provides free mediation and adjudication for disputes up to Rs. 50 lakh. File within one year of the insurer's final rejection. The Ombudsman's decision is binding on the insurer if you accept it; you retain the right to pursue further legal remedies if you do not.

Step 4: Challenge pre-existing condition denials specifically

If a PED exclusion is applied, request clarification of which PED clause is being applied and its duration. If the waiting period has elapsed, cite the policy year and document that the exclusion no longer applies. If your policy is more than 8 years old and the denial is based on non-disclosure, cite the moratorium clause directly.

Step 5: File with the Consumer Forum if the Ombudsman route is insufficient

File a complaint with the appropriate District Consumer Disputes Redressal Commission (DCDRC) under the Consumer Protection Act, 2019. Claims up to Rs. 1 crore go to the District Commission; Rs. 1–10 crore to the State Commission; above Rs. 10 crore to the National Commission. Filing fees are nominal. Courts routinely award the claim amount plus interest and damages for deficiency of service.

Step 6: Document the sub-limit dispute if room rent capping is involved

If your claim was reduced or denied due to room rent sub-limits, review your policy carefully. Document the specific room rent cap, your actual room rate, and calculate whether the insurer's proportional reduction formula was applied correctly per IRDAI guidelines — errors in the calculation formula are common.
