Health Insurance Claim Denied in Kolkata? How to Appeal

Kolkata has a long-established insurance market with a significant concentration of PSU (public sector undertaking) insurer policyholders — United India Insurance and New India Assurance have historically dominated the retail market in West Bengal. While private insurers like Star Health and Care Health are growing, many Kolkata families still hold legacy Mediclaim policies from PSU insurers. When these older policies get denied, the reasons and the appeal process have specific characteristics worth understanding.

If your claim was denied after treatment at Apollo Gleneagles in Rawdon Street, Fortis Hospital in Anandapur, AMRI Hospitals, or Peerless Hospital, here is your complete guide.

Common Denial Reasons in Kolkata

PSU policy sub-limits: New India Assurance and United India Mediclaim policies carry disease-specific sub-limits that are often decades old. Cataract surgery may be capped at ₹15,000–₹20,000, while actual costs run ₹40,000–₹70,000 per eye at Apollo or Fortis Kolkata. The sub-limit denial is technically correct per policy terms, but escalation can still win proportional relief.

Pre-existing disease waiting periods: Kolkata's older policyholders have high rates of cardiac disease, hypertension, and diabetes. PED denials for these conditions within 2–4 year windows are extremely common with both PSU and private policies.

Cashless rejection at non-empanelled hospitals: Apollo Gleneagles and Fortis Anandapur are empanelled with most major insurers, but some Kolkata nursing homes and smaller hospitals are not. Patients treated at non-network facilities and filing reimbursement claims face higher Denial Rates by Insurer (2026)" class="auto-link">denial rates.

TPA processing errors: Many PSU policies in Kolkata are processed through Third Party Administrators. TPA errors — wrong coding, missing pre-authorization, administrative delays — account for a significant number of denials that are correctable on appeal.

Non-medical expense exclusions: Items like diet charges, telephone charges, and certain consumables are commonly deducted. IRDAI's 2016 circular on non-medical expenses prohibits arbitrary exclusions of genuinely necessary items.

Key Insurers in Kolkata and West Bengal

• United India Insurance (PSU) — large retail base in West Bengal
• New India Assurance (PSU) — Mediclaim policyholders across Kolkata and districts
• National Insurance Company (PSU, headquartered in Kolkata) — significant local presence
• Star Health and Allied Insurance — growing private market share
• Care Health Insurance — urban Kolkata individual and group plans
• HDFC ERGO — corporate and group policies

Step 1: Internal Grievance to the PSU Insurer

For PSU insurer denials (New India, United India, National Insurance), write to the branch office where your policy is serviced and simultaneously to the Grievance Cell at the regional/zonal office. PSU insurers have a more structured (if slower) internal process.

Under IRDAI rules, even PSU insurers must respond within 15 working days. Reference your policy number, the rejection letter date, and request a detailed written explanation of the sub-limit or exclusion applied.

Step 2: IGMS Portal

File at policyholder.gov.in to register your complaint under IRDAI's IGMS system. Even PSU insurer complaints are tracked through IGMS. IRDAI's oversight creates accountability that direct insurer grievances lack.

You can also call Bima Bharosa at 1800-4254-732 (toll-free).

Step 3: IRDAI Insurance Ombudsman — Kolkata Office

The Kolkata Ombudsman covers West Bengal, Sikkim, and Andaman & Nicobar Islands.

• Eligible disputes: up to ₹50 lakh
• Process is free
• Decision within 3 months
• Award is binding on the insurer
• File within 1 year of insurer's final rejection

National Insurance Company is headquartered in Kolkata, and its disputes are heavily represented before the Kolkata Ombudsman. The office has considerable experience with legacy PSU Mediclaim sub-limit disputes.

Step 4: Consumer Court

The West Bengal State Consumer Disputes Redressal Commission and Kolkata District Forum handle insurance disputes. PSU insurer denials have been repeatedly set aside by consumer courts in West Bengal for deficiency of service.

Tips for Kolkata Policyholders

• PSU policy document: Pull your original policy terms from the branch office if you don't have a copy. PSU insurers are required to provide this.
• National Insurance Kolkata disputes: The insurer's head office being local means you can visit in person — sometimes a personal visit to the grievance cell accelerates resolution.
• Apollo Gleneagles billing: Apollo's insurance desk provides itemized breakdowns that make it easier to challenge arbitrary line-item denials.
• West Bengal government schemes: If you hold coverage under state government schemes alongside private insurance, coordinate-of-benefits disputes may arise. The Ombudsman can clarify which insurer pays what.
