COBRA Coverage Lapse and Claim Denied: Election Period and Retroactive Coverage Rights

COBRA continuation coverage is a critical safety net that allows employees who lose their job-based health insurance to continue that coverage temporarily at their own expense. But COBRA's rules are complex, the timelines are strict, and administrative errors — both by employers and plan administrators — frequently cause coverage lapses that result in denied claims. If your COBRA claim was denied due to a coverage lapse or election dispute, you have more rights than you may realize.

Understanding COBRA Election Rules

When a qualifying event occurs — job loss, reduction in hours, divorce from a covered employee, or other triggering events — the employer is required to notify the plan administrator within a specific timeframe. The plan administrator then has 14 days to send you a COBRA election notice.

From the date you receive that notice, you have 60 days to elect COBRA continuation coverage. This is a federal right under the Employee Retirement Income Security Act (ERISA).

Here's the critical point that many people don't know: if you elect COBRA within the 60-day window, coverage is retroactive to the date your prior coverage ended. This means even if you didn't pay premiums for weeks after the election, once you elect and pay, claims from the retroactive coverage period should be covered.

Common Reasons COBRA Claims Are Denied

Late election due to inadequate notice. The single most common source of COBRA disputes is failure to receive the required election notice. Employers frequently fail to send the notice on time, send it to the wrong address, or send it without adequate information about election deadlines. If you never received proper notice, federal law typically extends your election period.

Premium payment issues. COBRA premiums are expensive — often 102% of the group plan premium. If you elected COBRA but fell behind on premium payments, coverage may have terminated. However, insurers must provide a 30-day grace period for premium payments. Claims denied for a missed payment during the grace period should be reconsidered.

Plan administrator error. Employers and plan administrators sometimes process COBRA elections incorrectly, fail to notify the insurer of your election, or apply premium payments to the wrong period. These administrative errors are common and are legally the employer's or administrator's responsibility to correct — but you'll need to document the error and fight for correction.

Gaps between COBRA and new coverage. When people transition from COBRA to new employer-sponsored coverage or marketplace coverage, gaps of a few days or weeks sometimes create situations where claims fall through the cracks. Understanding exactly when coverage began and ended is essential.

COBRA exhaustion before end of qualifying period. COBRA generally provides 18 months of continuation coverage, or 36 months for some qualifying events. If you believed you had more coverage remaining than you actually did, claims may be denied after your COBRA period expired.

Your Rights Under Federal Law

COBRA is a federal law administered under ERISA for employer group plans. This means:

• You can file a complaint with the U.S. Department of Labor's Employee Benefits Security Administration (EBSA) if your employer or plan administrator failed to provide proper COBRA notice
• You can sue your employer under ERISA for failure to comply with COBRA notice requirements
• Employers can face significant penalties for COBRA notice violations — up to $110 per day per qualified beneficiary

If inadequate notice caused you to miss your election window and incur medical expenses as a result, you may have a claim not just against the insurer but against your former employer.

Steps to Take After a COBRA Coverage Denial

Reconstruct your COBRA timeline. Document exactly when your employment ended, when you received (or should have received) the election notice, when you elected, and when you made or attempted to make premium payments. Any gaps in this timeline that are attributable to the employer or administrator's failure to comply are grounds for appeal.

Request the COBRA election notice documentation. Under ERISA, you have the right to request all plan documents, including records related to your COBRA election, from the plan administrator. Request these in writing within 30 days of your claim denial.

File with the Department of Labor. The DOL's EBSA handles COBRA complaints. Filing a complaint creates an official record and may prompt corrective action, including retroactive coverage reinstatement.

Contact your state insurance commissioner. While COBRA is primarily federal, state insurance commissioners sometimes have concurrent jurisdiction over claims handling issues and can facilitate resolution.

Consult an ERISA attorney. For significant medical bills that arose during a disputed COBRA lapse, an ERISA attorney can evaluate whether you have a viable claim against your former employer or plan administrator for failure to comply with COBRA requirements. Many ERISA attorneys offer free initial consultations.

Paying Retroactively to Reinstate Coverage

If your coverage lapsed because you delayed payment after a valid election, you can often pay the overdue premiums retroactively to reinstate coverage and have previously denied claims covered. Contact your COBRA administrator immediately, ask whether retroactive payment is possible, and confirm in writing that premium payment will reinstate coverage back to the lapse date.
