ACA Admin: Setting Up ACA Look Back Method

What is the Look Back Method?

The look back method for measuring employee eligibility for insurance and full time status is a bit more complex than the monthly measurement option. This option allows you to track employee hours from their hire date for a longer period of time to determine if they meet full or part time status requirements and should be offered insurance. This method will consist of longer cycles where employees will go through a measurement, administration, and stability period. 


Monthly Measurement vs. Look Back Method

When the monthly measurement method is used to confirm an employee as full-time, an offer of coverage would have to be made the first day after the next two full months from the month for which eligibility was determined. 

If you use look back measurement, you will enter your employer settings in administration and cycles will be generated for each employee. Look back periods allow employees to have a longer measurement period before offering insurance but they also lock in an eligibility status for a longer time.

Monthly measurement means they evaluate an employee's full time status every month. If the monthly measurement option is used, you will not need to enter information in the employer settings and will not have cycles generated. Instead, the employee hours reports will be used to determine who hit the hours threshold each month.

*Note* We strongly suggest monthly measurements for clients who go live on new software midyear.  This means you measure who is full time and offer them insurance for the month that they were full time.  This is something we can track in the system off new and past employees (past employees so long as they have a txns conversion).



Setting Up the ACA Cycles for the Look Back Method

If you are going to utilize the Look Back Method, there will be some additional setup requirements for your administrators before you begin entering ACA dates, etc. 

*Note* Before you set up your ACA Cycle information in Enterprise, make sure you have your benefit information with you to make it easy for you enter the correct information the first time. Keep in mind that ACA information is typically different for each EINC or Employer so you may need to walk through the setup for multiple hierarchies depending on your company. 

To Find ACA Cycle Admin Settings:
  1. In Enterprise, navigate to All Options > Administration
  2. Select Employers 
  3. Double click on the employer on the list you want to set up ACA Cycle information for
  4. Select ACA Setup on the left 


Entering Applicable ACA Cycle Information

When you first start using the look back method, you will need to set up your cycle settings in administration:

*Note* Always work with your benefits provider or a legal advisor if you are unsure of any of the following ACA Cycle settings. 

Employer ACA Look Back Setup

The following table walks through the different fields you will need to fill out in order to set up your look back method

Field NameDescription
Transitional PeriodThis drop down was used for those transitioning to ACA look back method back when ACA was first starting out. 
Administrative PeriodEnter the number of days that employees have to accept or decline their insurance option.
  • The administrative period is the period of time between when an employee is eligible for insurance and the time that you must have them enrolled in an insurance plan. 
  • The maximum length of an administrative period is typically 90 days, however when selecting your administrative period you will want to take into consideration insurance enrollment dates as they correlate to hire dates. 
  • In other words; if your insurance enrollment only allows for beginning of the month enrollments (vs weekly) you may want to consider a 60 day administrative period.

*Note* Employees who are not being offered coverage will still be reflected in the administrative period.

Delay Initial Measurement Period

Click to put an X in the box if you would like the insurance coverage start date delayed to the first day of the following month after enrollment. 

  • You will want to check this box if your insurance company does not allow mid-month enrollments for employees. 
  • If this box is checked and you have a 90 day administrative period, the system calculations will take this into account when doing the insurance due date calculation. In other words you do not need to modify your administrative period to less than 90 days to accommodate the insurance coverage start date delay. 

Initial Measurement PeriodSelect a length in months in the drop down field
  • The reason the initial measurement period exists is when a variable-hour employee starts working for you, you don't have any hour's history to determine their insurance eligibility and they might have begun working in the middle of the standard measurement period. 
  • Because it wouldn't be fair to you or them to judge simply based off of how much they worked in the remainder of the standard measurement period, the initial measurement period exists to give you time to gather that information before their eligibility is determined and you start facing penalties.
Insurance CutoffEnter a day of the month that employees need to be enrolled by if you are doing monthly enrollments
  • The insurance cut off is the day of the month that your insurance enrollment is due. This field will be used to calculate approaching non-compliance of enrollment for eligible employees.
  • If you allow your employees to enroll weekly, enter 0 in this field
Standard Measurement Period

Select a length in months from the drop down field. 

  • The standard measurement period is used for employees who have worked the full number of months of your transitional period or your initial measurement period. 
  • When determining whether or not ongoing employees are eligible for health insurance, you look at the hours worked by those employees during the standard measurement period (or transitional period for year one of ACA). 
  • In order for an employee's ACA status to be determined based off of the standard measurement period, they must have worked the entire duration of the standard measurement period. In short, it is the period of time that you use to determine insurance eligibility for the next stability period.

Standard Measurement Period End DateEnter the date your standard measurement period ends here.
  • The time between the end of your standard measurement period and the start of the next stability period is your administrative period. 
  • So, if your stability period starts on January 1st and your administrative period is 90 days, your standard measurement period must end no earlier than October 2nd.
Stability PeriodSelect a length in months for your stability period.
  • The stability period is the period of time after the start of the insurance requirement that any eligible employee regardless of ongoing ACA status must have insurance available to them. 
  • Your stability period may not be less than your transitional period or measurement periods.Another way of looking at the stability period is it is the period of time between insurance open enrollment periods. 
    • So if your insurance enrollment period ends April 30th and reoccurs yearly, then your stability period would be 12 months long and start on May 1st. 
  • The significance of this period is if it has been determined that an employee should receive insurance, they may not have their insurance terminated until the end of the stability period unless their employment is terminated as well. 
    • E.g. John Doe worked 32 hours per week for the past year and we gave him insurance starting May 1st and have selected a 12-month stability period. On June 30th, John comes to us and lets us know that he is only able to work 20 hours per week due to family reasons. Due to the quality of John's work, we want to keep him around. Despite knowing that John is only going to be working 20 hours per week, we cannot revoke his insurance until May 1st of the following year without incurring penalties
    • There may be exceptions to this rule - work with your benefits provider or legal advisor to determine if an employee's insurance can be revoked in different scenarios. 
Stability Period Start DateEnter the first date following open enrollment period.
  • The stability period start date is the first date following the open enrollment deadline date, or you may look at it as the start date of your insurance plan coverage period
Approaching FT Threshold

Enter in a number of weekly hours in this field. This number is used in system calculations for any employees not coded with an ACA status of fulltime. 

  • This calculation uses the employee's average weekly hours during the current measurement period (either initial measurement or standard measurement depending on which period they are in) to flag the employee as approaching full time equivalent (FTE) status. 
  • These calculations will be performed during the daily maintenance procedure that is automatically run on your system.

ACA Cycle Overview

How our system tracks ACA Look Back Cycles: 

Setting Hire Dates

Your recruiters or team members will set the ACA hire date for the employees under the pay setup section of the employee's record. 

The system will check daily to update the employee's cycle status

Current Cycle

Employees will start with a measurement period where the employee's status and hours worked will be evaluated to see if they qualify for insurance. 

After the measurement period, the employee will go into the administration period where you will review their average hours, update their ACA status if necessary, and potentially offer them insurance. 

Employees will either accept or decline insurance options given and then the employees will be put into a stability period

During the stability period, they will continue to be covered by insurance even if their hours change each week. The system will continue to count the days of the stability period. 

Employees who continue to be employed by you will enter a new measurement period in order to review if they will continue to qualify for insurance after the next open enrollment session. This new measurement period may overlap with their first stability period depending on when they were hired vs. when your yearly open enrollment session is. 

Break In Service

A break in service is detected in the system when an employee that is currently on an ACA cycle has not worked for a 13 week period or more, or the employee has not worked for 4 weeks or more, where that 4 week break is greater than the preceding work period (e.g. 3 week assignment followed by a 4 week break).
