Cigna Medicare Supplement Plans Review 2026

Cigna does something that caught our attention when we were reviewing Medigap providers: they give you up to 25% off your premium just for enrolling online instead of over the phone. That’s a meaningful discount — potentially hundreds of dollars a year — and it’s not something most other Medigap carriers offer.

We looked at Cigna’s Medigap plans alongside their main competitors (Humana, Aetna, Mutual of Omaha) to see where they stand on pricing, plan selection, and overall value. They don’t offer as many plan letters as some competitors, but the plans they do sell are the ones most people actually want — G, N, and A.

Our writer David Chen got a Plan G quote from Cigna while researching this piece and compared it to quotes from three other carriers for the same zip code. With the online discount applied, Cigna came in second-lowest. Without it, they were middle of the pack. The moral: if you’re considering Cigna, use the online enrollment. Medicare plan costs change annually, so verify current premiums and coverage at medicare.gov or with a free SHIP counselor. Have a question we didn’t cover?

Cigna Medicare Supplement Plan Review 2026

Cigna is one of the major national Medigap providers, offering a solid selection of Medicare supplement plans backed by an extensive provider network and a notable online enrollment discount.

Cigna’s Position in the Medigap Market

Cigna enters the Medigap market as a well-established name with strong brand recognition and national infrastructure. Their Medicare supplement plans emphasize straightforward coverage with the option to save significantly by enrolling online rather than through a phone agent.

Key findings from our research:

• Online enrollment can save up to 25% compared to phone enrollment
• Broad national provider network
• Plans available in most states
• Strong financial stability

Pros and Cons

Pros:

• Online enrollment discount up to 25%
• Extensive provider network
• Household discount available
• Strong financial ratings
• Plans A, G, and N available in most markets

Cons:

• Fewer plan options than some competitors (no Plans B, D, K, L, M)
• Availability varies by state
• Customer service reviews are mixed compared to some competitors

Cigna’s Medigap Plan Options

Cigna offers a focused selection of Medigap plans:

Plan A — Basic Coverage

Plan A is the most basic standardized Medigap plan, covering:

• Part A coinsurance and hospital costs (up to 365 extra days)
• Part B coinsurance
• First three pints of blood
• Part A hospice care coinsurance

Best for: Seniors who want only the most essential gap coverage at the lowest premium.

Plan G — Maximum Protection

Plan G is Cigna’s most comprehensive plan for new Medicare beneficiaries. It covers everything Plan A does, plus:

• Skilled nursing facility coinsurance
• Part A deductible
• Part B excess charges (the difference if a doctor charges above Medicare-approved rates)
• 80% foreign travel emergency coverage

After paying the Part B deductible ($257 in 2026), you have essentially zero out-of-pocket exposure for Medicare-approved services.

Best for: Seniors who want comprehensive coverage and predictable costs.

Plan N — Cost-Sharing Balance

Plan N offers lower premiums than Plan G in exchange for modest copays:

• Up to $20 for covered office visits
• Up to $50 for emergency room visits that don’t result in an admission

Plan N does not cover Part B excess charges or the Part B deductible.

Best for: Relatively healthy seniors who want significant protection at lower monthly cost.

High-Deductible Plan G

In some markets, Cigna offers a high-deductible version of Plan G. You pay all costs until reaching a high deductible threshold (around $2,870), after which Plan G coverage kicks in fully. Premiums are much lower than standard Plan G.

Best for: Healthy seniors comfortable with higher out-of-pocket risk in exchange for very low premiums.

Understanding Cigna Medigap Plan Costs

Medigap premiums depend heavily on your age, gender, state, and tobacco use. Cigna uses attained-age rating in most markets, meaning premiums increase as you get older.

For a rough benchmark: a 70-year-old woman in a major metropolitan area might pay $150–$200/month for Plan G through Cigna, depending on location. Get a personalized quote for your specific circumstances.

The Online Enrollment Discount

One of Cigna’s most distinctive offerings: applying online rather than through a phone agent can save up to 25% on your premium. Over the course of a year, that discount can amount to several hundred dollars.

If you’re comfortable using Cigna’s online enrollment platform, this is a significant financial incentive not available with most other Medigap insurers.

How Cigna Compares to Competitors

Cigna vs. Humana

Humana has broader plan availability (more plan letters) and all-50-state coverage. Cigna’s advantage is the online enrollment discount, which can make Plan G significantly cheaper. Compare actual quotes in your zip code to decide.

Cigna vs. Anthem Blue Cross

Anthem covers more states through its BCBS subsidiaries but is limited to 14 states. Cigna’s online discount is a differentiator. Both offer competitive Plan G pricing.

Cigna vs. Aetna

Both emphasize competitive premiums. Aetna is often the cheaper quote for older enrollees; Cigna’s online discount can level the playing field or favor Cigna. Get quotes from both.
