Letter of Guarantee is an assurance of payment offered by AIA confirming that the cost of medical treatment is eligible under the plan and will be covered by AIA. This letter is only applicable for AIA panel and platinum hospitals.
There are some specialists within the appointed panel hospitals that do not have any working arrangement with AIA. Insured Persons who seek treatment from non-AIA panel doctors will have to pay the charges in full and submit your claim with all the supporting documents to AIA for reimbursement.
