Why Do Health Insurance Claims Get Rejected in India?
Health insurance claim rejection occurs when an insurer partially or fully denies payment for a hospitalization claim. Rejections can be outright (zero payment) or partial (deductions from the approved amount). The most common triggers are: (1) waiting periods/exclusions not met, (2) non-disclosure or mismatch in medical history, (3) room rent/co-pay/sub-limit deductions, and (4) missing or inconsistent documentation.
According to IRDAI data, approximately 5–8% of health insurance claims in India are rejected outright, while an additional 25–35% face partial deductions. The single largest cause of rejection remains non-disclosure of pre-existing diseases, accounting for an estimated 15–25% of all disputed claims. Room rent proportionate deductions affect approximately 25–30% of hospitalization claims, and documentation gaps cause 10–15% of delays or partial denials. The critical insight: approximately 70% of rejected or disputed claims are reversible with the right documentation, a clear written response, and timely escalation through the insurer's grievance process.
