COBRA Disability Extension: When Coverage Runs To 29 Months
A qualified beneficiary who is disabled can extend COBRA coverage by 11 months, for a total of 29 months. The extension has strict notice timing and a different premium rule. Here is how it works for employer group health plans.
How The Disability Extension Works
11 More Months
When a qualifying event is a termination of employment or reduction in hours, COBRA normally lasts 18 months. A disability extension adds 11 months, for a total of 29 months. Employers should make sure COBRA notices and administrator procedures describe the extension, so qualified individuals know to ask about it. Counsel or the COBRA administrator can confirm how it applies to a particular plan. Try our free disability income gap calculator to run the numbers for your own group.
Social Security Determines Disability
The Social Security Administration must determine that the qualified beneficiary is disabled. That determination must be made before the 60th day of COBRA coverage, and the disability must continue through the 18-month period. Because the timing depends on a federal agency decision, employees often need early help gathering records. HR can remind them to send a copy of the determination to the plan administrator promptly and to keep proof of what was sent. To check your own dates, use our free COBRA end date calculator.
Whole Family Can Extend
If one qualified beneficiary is disabled, the extension applies to all qualified beneficiaries in the family who are covered under COBRA from the same qualifying event, not only the disabled person. Employers should make sure notices go to every covered family member who may be affected, and that the administrator tracks each person’s coverage dates. Counsel can help if family members have different qualifying events or enrollment situations. The tax treatment of COBRA premiums is covered in COBRA Premium Tax Treatment.
Notice To The Plan Has A Deadline
Plan Sets The Period
The plan sets the period for notifying it of the disability determination. The period must be at least 60 days and runs from the latest of several dates, including the date of the Social Security determination, the qualifying event, the loss of coverage, or when the person was informed of the notice duty.
Before The 18 Months End
Notice must also be given before the end of the initial 18-month period, even if the plan allows more time on paper. Employers can build this date into their administrator’s tracking process and remind employees early, since late notice can end the opportunity. Counsel can explain what the plan and the law require when a notice is delayed.
Put It In The Plan Documents
The election notice and summary plan description should explain the procedure and who to notify. A clear procedure helps avoid disputes over late notice. Review the documents with counsel or the administrator whenever the plan changes, and confirm the contact information is current. Employees are far more likely to give notice on time when the instructions are clear and easy to find.
Premiums During The Extension
Up To 150 Percent
During the 11-month extension, the plan may charge up to 150 percent of the cost of coverage, rather than the usual 102 percent. Employers and administrators should confirm the rate in writing and explain the higher charge in the notice, so employees are not surprised by a bill. Counsel can confirm how the percentage applies to a given plan and period.
If The Disabled Person Does Not Extend
If the disabled person does not take the extension, the plan may still charge 102 percent to the non-disabled family members who continue coverage. Administrators need to track which family members are on which rate and when it changes. Clear billing records help employers explain the difference to families, and counsel can confirm the rules in any unusual situation.
Other Rules Still Apply
The ordinary billing rules, grace periods and payment options continue to apply. See our COBRA billing guidance. Employers should confirm that the administrator applies the same payment deadlines and grace periods during the extension as before. Families on a disability extension may be under financial strain, so clear and early communication about due dates is important.
When The Extension Can End
No Longer Disabled
The extension can end if Social Security determines the person is no longer disabled. The qualified beneficiary must notify the plan, and the plan must allow at least 30 days after that determination to give notice. Employers and administrators should keep a record of each notice and the date it was received. Counsel can help if the dates are unclear, and the plan documents should describe what happens when coverage ends because disability has ended.
Medicare Entitlement
Other COBRA termination events, including Medicare entitlement after the election, can also end coverage. See how COBRA and Medicare interact. Employees who may become eligible for Medicare should talk with the administrator and a benefits adviser before making decisions, because the order of events can change what coverage remains. Counsel can advise on the specific termination rules.
Keep Records
Keep the notice, the Social Security determination and the premium history together in the file for each qualified beneficiary. A well kept file makes it easier to answer questions from the beneficiary, the carrier or an auditor. Limit access to people who need the information, and ask counsel how long records should be retained under your policy.
