Out-of-pocket health insurance costs persist due to policy exclusions and billing practices

Patients often face substantial bills despite health insurance coverage as hospital charges, policy exclusions, and billing rules lead to significant claim shortfalls. Experts advise careful policy selection and meticulous documentation to minimise out-of-pocket expenses.

Health insurance can still leave patients with a sizeable bill, and the shock usually comes at discharge. A hospital may raise a final invoice of ₹5 lakh, yet the insurer may settle only ₹3.5 lakh or ₹4 lakh, leaving the family to cover the rest. According to reports by Mint, SMC Insurance and CrediHealth, that shortfall is often driven by policy exclusions, billing rules and treatment limits rather than a simple refusal to pay.

One common reason is that hospitals charge for items insurers classify as non-payable. These can include gloves, masks, syringes, cotton, bandages, admission fees, filing charges and other consumables, as well as comfort and administrative costs. SMC Insurance and Mint both note that such items are frequently excluded, which is why even a cashless claim may still leave out-of-pocket expenses.

Another major trigger is room-rent limits. If a policyholder chooses a room above the entitlement in the policy, insurers may not only reduce the room charge itself but also apply a proportionate cut to related expenses such as surgeon fees, nursing charges, diagnostics and theatre costs. Mint says this is one of the biggest reasons claims are trimmed, especially in older or lower-premium plans where room caps are common.

Co-payment clauses and deductibles can also reduce the amount paid. Under a co-payment rule, the customer must bear a fixed share of the admissible bill, which is especially common in senior-citizen policies and some zone-based plans. Deductibles work differently: they require the policyholder to pay the first part of the bill before insurance begins to respond. CrediHealth and other consumer guidance sources say these clauses are often misunderstood until the claim is filed.

Some policies also impose sub-limits on specific illnesses or procedures. That means a plan may have a large overall sum insured but still cap payment for cataract surgery, hernia treatment, kidney stones or knee replacement. In addition, insurers often reject or reduce items that are not properly supported by the medical records, such as unrelated tests, missing receipts, tonics, supplements or expenses not tied clearly to the hospital stay. SMC Insurance and other explainers say poor documentation is a frequent reason for partial approval.

If a settlement looks wrong, the first step is to study the explanation of benefits and compare it line by line with the hospital bill. If the hospital has coded something incorrectly or failed to justify a charge, the treating doctor can provide a medical justification letter and the billing team can issue a revised break-up. From there, policyholders can take the matter to the insurer’s grievance cell, then to the IRDAI’s Bima Bharosa portal or the insurance ombudsman if the dispute remains unresolved. Consumer guidance from NYVO and others says many rejected or reduced claims can be corrected when the exact reason is challenged with the right documents.

The best protection, insurers and advisers say, is to buy with the claim in mind. That means checking for room-rent limits, co-payments, deductibles, sub-limits and exclusions before choosing a plan. Some policies also offer add-ons for consumables, no room-rent cap and no co-payment, which can reduce the risk of unpleasant surprises during treatment.
