National Insurance Company Claim Denied? How to Appeal in India
National Insurance Company Limited (NICL) is one of India's four PSU (Public Sector Undertaking) general insurers, wholly owned by the Government of India. It is one of the oldest and largest insurance companies in the country, with its registered and head office in Kolkata. NICL offers health insurance products including Parivar Mediclaim Policy, Mediclaim 2012, Varistha Mediclaim (senior citizens), and corporate group Mediclaim policies.
Despite being a government-owned insurer, National Insurance policyholders regularly encounter claim denials — often on grounds of pre-existing diseases, documentation deficiencies, or medical necessity disputes. This guide explains how to challenge those denials.
Common Reasons National Insurance Denies Claims
- Pre-existing disease (PED) exclusions: NICL commonly invokes PED clauses for conditions like hypertension, diabetes, kidney disease, or cardiac conditions, particularly in the first 1–4 years of coverage.
- Non-disclosure and misrepresentation: The insurer or its TPA alleges that the policyholder did not disclose relevant medical history at the proposal stage, leading to policy repudiation.
- Documentation deficiencies: Missing original bills, incomplete discharge summaries, absent investigation reports, or the failure to submit documents within prescribed timeframes.
- Medical necessity disputes: NICL's TPAs (typically Genins India, Medi Assist, or others depending on region) may dispute whether a surgery, investigation, or extended inpatient stay was medically necessary.
- Policy lapse: Denials citing a break in continuity due to delayed premium payment.
- Network hospital restrictions: Cashless rejections at hospitals not on NICL's empanelled network, followed by reimbursement denials.
- Sub-limit breaches: Policies with specific sub-limits on room rent, ICU charges, or particular procedures may result in partial denials.
Step 1: Read Your Denial Letter Carefully
National Insurance is legally required under IRDAI regulations to provide a written denial citing the specific policy clause and reason. If your denial came from a TPA on NICL's behalf, you can request the insurer's own written confirmation.
The denial reason is critical — it determines the legal and medical arguments you need to make in your appeal.
Step 2: File a Formal Internal Complaint With NICL
National Insurance has a Grievance Redressal Officer at its regional and divisional offices. File a written complaint with:
- Your policy number and claim reference number
- Denial letter or TPA intimation
- Clear reasons why you believe the denial is incorrect
- All supporting documents (discharge summary, bills, treating doctor's certificate)
NICL grievance contact options:
- Visit the local divisional or regional office (NICL has offices across all major cities)
- Email the GRO at the regional office (addresses available on the NICL website)
- File online through NICL's customer portal
IRDAI-mandated timelines:
- Acknowledgment: 3 working days
- Resolution: 15 days
PSU insurers like NICL are sometimes slower to process internal grievances compared to private insurers. If you do not receive a response within 15 days, escalate immediately to IGMS.
Step 3: File on IGMS
The IGMS portal (igms.irda.gov.in) is IRDAI's centralized grievance tracking system. Filing here is especially effective against PSU insurers because IRDAI monitors PSU insurer compliance closely.
Upload your denial letter, hospital documents, and prior complaint correspondence. IGMS records are visible to IRDAI supervisors, and complaints against PSU insurers are reviewed under IRDAI's oversight mandate for public sector companies.
Step 4: Insurance Ombudsman
The Insurance Ombudsman system has 17 offices across India, each covering a defined geographic region. Identify the Ombudsman office for your state (based on where the policy was issued or where you reside).

The Ombudsman process is free of charge and binding on the insurer.
Understanding NICL's Key Products
Parivar Mediclaim Policy covers the entire family under a single sum insured, with defined sub-limits and waiting periods. Appeals for Parivar Mediclaim denials should specifically reference the family floater terms.
Mediclaim 2012 is NICL's standard individual health policy. Denials under this policy often relate to interpretation of PED clauses or specific exclusion lists.
Varistha Mediclaim is for senior citizens and has unique age-specific terms. Denials under this policy may involve age-related condition exclusions.
Step 5: Consumer Court
If the Ombudsman process does not result in a satisfactory resolution, or the claim amount exceeds the Ombudsman's Rs. 50 lakh limit, file a complaint with the Consumer Disputes Redressal Commission at the appropriate level. Consumer courts have regularly awarded NICL policyholders full claim settlements plus compensation for mental agony and harassment.
