FSA Annual Unsubstantiated Claims Process

Posted 1:30 p.m. Friday, Feb. 3, 2023

FSA Unsub Claims

For employees who elect FSA contributions be deducted from their paycheck, it is important to understand the basics of the Healthcare FSA Unsubstantiated Claims Process and know about the upcoming deductions beginning on 2/9/2023.

If a health care FSA payment card transaction is not automatically substantiated, you will be notified of an “unsubstantiated claim” that needs to be resolved by substantiation, substitution, or repayment. You will receive notices about the unsubstantiated claim via the email address associated with your Optum account:

  • 10 days after the transaction
  • 40 days after the transaction
  • 70 days after the transaction

If your claims are not resolved within 85 days, your payment card will be deactivated (until your claims are resolved). Check the junk folder in your email for these notices. If you do not have an email address associated with your Optum account, the notices will be sent via U.S. Mail.

The FSA administrator sends these notifications for every health care FSA unsubstantiated claim throughout the year.

Payroll Withholding Process:

In January, Optum will provide a report to the UW System reflecting employees with health care FSA unsubstantiated claims (incurred on/prior to 12/31/2022). The report is used for the payroll withholding process.

UW System will send an email to the affected employees to make them aware of the payroll withholding process, and that it will continue through March (even if claims are substantiated during the process). Payroll deductions will occur as follows:

Balance AmountAction
At or less than $100The balance will be taken from your 2/9/2023 paycheck.
Greater than $100The balance will be divided by four and even deductions will be taken from four paychecks. Pay dates are listed below.

Deductions will be withheld from the following paychecks:

  • 02/09/2023
  • 02/23/2023
  • 03/09/2023
  • 03/23/2023
