Understanding COBRA and Medigap Coverage: Costs and Key Differences
When you lose employer health coverage, understanding your options becomes critical. COBRA and Medigap represent two distinct pathways for maintaining healthcare coverage, each with unique benefits, costs, and eligibility requirements. This guide explains both options to help you make informed decisions about your healthcare coverage.
What is COBRA Coverage?
COBRA allows eligible employees and dependents to continue employer-sponsored health insurance temporarily after job loss or qualifying events. You pay the full premium plus a 2% administrative fee, typically costing 102% of the group plan rate. COBRA generally lasts 18 months for job loss, 36 months for other qualifying events, and covers the same benefits as your previous employer plan.
Understanding Medigap Plans
Medigap supplemental insurance works alongside Original Medicare Parts A and B to cover costs Medicare does not. These private insurance policies help pay deductibles, coinsurance, and copayments. Medigap plans are standardized across states, labeled A through N, with each plan offering different levels of coverage. Plans do not cover dental, vision, or prescription drugs.
Cost Comparison: COBRA vs Medigap
| Coverage Type | Monthly Cost Range | Covers Deductibles |
|---|---|---|
| COBRA | $400-$2,000+ | Yes, as original plan specifies |
| Medigap Plans | $100-$300 | Varies by plan (some cover all) |
| Medicare Part B Premium | $202.90 | No, separate deductible applies |
| Medicare Part A Deductible | $1,736 per benefit period | Covered by some Medigap plans |
COBRA premiums vary based on your previous employer plan but average significantly higher than Medigap. For those age 65 and older, Medigap combined with Medicare typically costs less than COBRA while providing comparable or better coverage. In 2026, Medicare Part B premium is $202.90 monthly, with Part A deductible at $1,736 and Part B deductible at $283.
Eligibility Requirements
COBRA eligibility requires you to have worked for a covered employer with 20+ employees and lost coverage through job loss or qualifying life events. Medigap eligibility requires enrollment in Medicare Parts A and B, typically available at age 65 or after a two-year wait period for those receiving Social Security Disability Insurance. Different rules apply for those with end-stage renal disease.
Open Enrollment Advantage
If you enroll in Medigap within 63 days of Medicare Part B enrollment, insurers cannot deny you coverage or charge more based on pre-existing conditions. This protection does not apply if you wait longer.
Enrollment Deadlines and Process
COBRA election must occur within 60 days of losing coverage. Medigap enrollment has a critical 63-day window from Medicare Part B enrollment start date. Missing these deadlines can result in coverage gaps, higher premiums, or denial of coverage. Late enrollment penalties can be permanent. Contact your former employer or Medicare directly to ensure timely enrollment and avoid penalties.
Choosing the Right Coverage
Choose COBRA if you are under 65, expect to work again soon, or need coverage for specific treatments during transition. Choose Medigap if you are 65+, retired, or plan long-term Medicare enrollment. Compare total costs including premiums, deductibles, and out-of-pocket limits. Your health status, age, and future coverage plans should guide your decision.
