Adding New Employees to Your Group Health Plan
New employees become eligible for group health insurance at the end of their waiting period — the period from hire date to coverage eligibility. California employers can set waiting periods of 0 days (immediate coverage), 30 days, 60 days, or 90 days. The ACA caps waiting periods at 90 days — longer waiting periods are illegal. Most carriers also require enrollment within 30 days of the eligibility date.
Common waiting period structures: "First of the month following 30 days" — if hired January 15, coverage starts March 1 (first of month following 30+ days). "First of the month following 60 days" — hired January 15, coverage starts April 1. Immediate — coverage starts day 1 of employment. Plan your waiting period based on your business needs: longer waiting periods save money for high-turnover positions; immediate coverage can be a strong recruiting signal for senior hires.
Enrollment Process for New Hires
Best practice new hire enrollment process: provide new hire with Summary of Benefits and Coverage (SBC) and enrollment materials on day 1 of employment (required under ACA); set a reminder for the enrollment eligibility date; send employee enrollment forms or online portal access approximately 2 weeks before eligibility; collect completed enrollment elections and submit to carrier before the eligibility date; confirm coverage effective date with carrier. Most carrier employer portals allow self-service new hire enrollment — employees enter their information directly, reducing HR data entry.
What Happens If an Employee Misses Enrollment
Employees who fail to enroll during their initial eligibility window are generally locked out of group coverage until the next annual open enrollment, unless they experience a Qualifying Life Event (QLE). It's the employer's obligation to inform new hires of their enrollment window and provide adequate materials. If an employee misses enrollment due to employer failure to notify them, consult with your broker and carrier about late enrollment exceptions.
HIPAA Special Enrollment Rights
HIPAA special enrollment rights allow employees who lose other coverage or experience a family status change to enroll in group health outside the standard enrollment window. Special enrollment triggers: loss of Medicaid or CHIP coverage, birth or adoption of a child, marriage or domestic partnership, court order requiring coverage. These special enrollment periods typically must be requested within 30 days of the event. Section 125 cafeteria plan documents must address special enrollment rights to maintain compliance.
