6. Hospitalization Below Minimum Hours

Most policies require minimum 24-hour hospitalization to be covered. Day-care procedures are covered under specific lists. Claims for short-duration hospitalizations not meeting the minimum threshold are rejected.

7. Non-Empanelled Hospital (Cashless Claims)

For cashless claims, the hospital must be on the insurer's network. If you get treated at a non-network hospital without prior emergency intimation, the cashless claim will be denied. Reimbursement may still be possible.

8. Incorrect or Incomplete Documentation

Missing original bills, prescription copies, diagnostic reports, or discharge summaries lead to claim rejections or shortfalls. Always collect every receipt and document during hospitalization.

9. Non-Medical Expenses Billed as Medical

Attendant charges, food charges, toiletries, laundry, telephone charges, and certain consumables are excluded from most policies. Hospitals sometimes bundle these into medical bills, and insurers deduct or reject these components.

10. Mismatch Between Diagnosis and Claimed Treatment

If the diagnosis on the discharge summary doesn't match the procedure or treatment claimed, the insurer investigates and may reject. This can happen due to hospital billing errors. Always verify your discharge documents.

11. Policy Lapsed at Time of Hospitalization

If you missed a renewal and the policy lapsed, any hospitalization during the lapsed period is not covered. Set up auto-renewal or reminders. Risk Scorecard Tool to assess your coverage needs
