Diabetes Treatment Denied in India: Appeal Guide

India is home to the world's second-largest population of people living with diabetes — over 100 million individuals. Yet insurance coverage for diabetes treatment remains one of the most contested areas in the country's rapidly evolving health insurance market. If your claim for diabetes care has been denied, you are far from alone, and you have more appeal options than most policyholders realise.

How Diabetes Treatment Is Covered in India

Ayushman Bharat – PMJAY: The Pradhan Mantri Jan Arogya Yojana (PMJAY), part of the Ayushman Bharat scheme, provides health coverage of up to ₹5 lakh per family per year for economically vulnerable households. PMJAY covers a defined package of hospitalisation-based treatments. Diabetes-related complications requiring hospitalisation — including diabetic ketoacidosis, diabetic foot requiring surgery, and renal complications — are included in PMJAY's Health Benefits Packages (HBPs). Routine outpatient diabetes management, medications, and tests are generally not covered.

Private health insurance: Private health insurance in India covers hospitalisation for diabetes-related complications, and some comprehensive policies cover day care procedures and advanced treatments. However, the pre-existing disease (PED) exclusion is the single biggest barrier for people with diabetes — most standard policies exclude diabetes-related conditions for 2 to 4 years from the policy start date before any related claims can be made.

IRDAI portability regulations: If you switch insurers, your pre-existing disease waiting period carries over proportionally — insurers cannot restart a fresh PED clock when you port a policy. This is a key right many policyholders are not aware of.

Common Reasons Diabetes Claims Are Denied in India

• Pre-existing disease exclusion applied: The insurer argues the hospitalisation is linked to a pre-existing diabetic condition and refuses to pay during the waiting period.
• Non-disclosure of diabetes at time of proposal: If diabetes was not disclosed when the policy was taken, the insurer may void the policy entirely or reject claims related to diabetes.
• Complications not listed in policy: Some budget policies do not list specific diabetic complications like retinopathy surgery or dialysis for diabetic nephropathy.
• Hospitalisation not meeting minimum duration criteria: Standard health policies require a minimum 24-hour hospitalisation for a claim to be valid. Day care procedures may not qualify unless specifically listed.
• Claim for outpatient medication: Insulin, metformin, and oral antidiabetics purchased on prescription are not covered under hospitalisation-only policies.

How to Appeal a Diabetes Insurance Denial in India

Step 1 — Internal grievance with your insurer: File a written grievance with your insurer's Grievance Redressal Officer (GRO). Every insurer is required by IRDAI to have a GRO and to resolve complaints within 15 days. Reference the IRDAI guidelines on pre-existing conditions and the specific policy clause being disputed.

Step 2 — IRDAI Bima Bharosa Portal: If your insurer does not resolve the complaint within 15 days or you are dissatisfied with the response, escalate to IRDAI through the Bima Bharosa portal (bimabharosa.irdai.gov.in) or call the IRDAI grievance call centre at 155255.

Step 3 — Insurance Ombudsman: India has 17 Insurance Ombudsmen covering different states and union territories. You can approach the Ombudsman in your region if your claim involves up to ₹50 lakh in dispute value. The Ombudsman process is free, and awards are binding on insurers. File at cioins.co.in.

Step 4 — Consumer Forum / NCDRC: For larger disputes or if the Ombudsman decision is unsatisfactory, you can approach the Consumer District Forum, State Commission, or National Consumer Disputes Redressal Commission (NCDRC) under the Consumer Protection Act 2019.

IRDAI Rules on Pre-Existing Disease Waiting Periods

IRDAI has introduced regulations limiting PED exclusion periods. The 2024 IRDAI Health Insurance Regulations require that PED waiting periods do not exceed 3 years (and many are being standardised at 2 years). If your insurer is applying a 4-year waiting period on a policy issued after these regulations took effect, that may be a compliance issue you can raise with IRDAI.
