The short
answer.

Most medical reimbursement claims need the claim form, original hospital bills and payment receipts, the discharge summary, prescriptions, test reports, pharmacy bills, your beneficiary or policy details, and bank details for payment. Some schemes also need an essentiality or emergency certificate.

The exact list depends on your scheme or insurer, the type of treatment and whether the hospital was empanelled or in-network. Always check the current requirements with your office, CGHS or your insurer or TPA before submitting.
