Benefits Plus is health insurance company that pays medical andhospital claims of the policy holders.

In order to havepolicyholder’s claims processed,policy holders must submit a claim form. All claims are eithermailed or presented in person to Benefits Plus' ClaimsProcessing Department. Claims forms are first checked byClaims Screening Clerks and any incomplete formsare returned to the claimant (policyholder) for completion. Detailsof those incomplete forms which are returned to the policy holderare first entered in a Claim Pending File. Eachweek this file is checked and any pending claimsmore than 45 days old are removed and the policyholder is notifiedby a letter that their case has been closed.

All complete forms, including those pending claims which havebeen resubmitted, are then passed to the ClaimsClerks who sort them according to the type of claim andassign a claim number to each claim form. The claims clerk thenretrieves the policyholder's policy record from the PolicyFiles and records policy and claim action details on theclaim form. The policy record is also updated with details of thecurrent claim and then refiled. A benefits cheque is then preparedand sent to the claimant along with a tear-off slip from theoriginal claim form. The tear-off slip serves as the claimant'srecord of their claim. Processed claim forms are filed by claimnumber after first being microfilmed for archival storagepurposes.

At the end of each day a summary of all claims processed is sentto the Claim Payments Records Section.
