Cigna Medicare Advantage Plans: Strengths, Weaknesses, and What to Know

Cigna merged with Express Scripts, one of the country's largest pharmacy benefit managers, in 2018, creating a combined company with significant leverage in prescription drug management. That integration shows in Cigna's Medicare Advantage products, which often feature competitive Part D drug benefits and strong mail-order pharmacy programs. Cigna's Medicare Advantage footprint is smaller than UnitedHealthcare, Humana, or Aetna, with a presence concentrated in specific markets where the company has invested in building networks.

Bryce's Take

Cigna is one I recommend in markets where their networks are strong and their pharmacy integration through Express Scripts gives clients a competitive drug benefit. They tend to have fewer plans in a given market than UHC or Humana, which actually works in their favor from a quality standpoint, since fewer plans means more focus. If Cigna is available in your zip code, they are worth including in the comparison.

Overview of Cigna Medicare plans

Cigna offers Medicare Advantage HMO and PPO plans in select markets, primarily in the Southeast, Midwest, and certain other regions. The company also offers standalone Part D plans nationally through its Express Scripts subsidiary and Medicare Supplement plans in some states. Cigna's Medicare Advantage plans are branded under the Cigna Achieve or Cigna Preferred names in most markets.

Strengths

Cigna's pharmacy integration through Express Scripts creates competitive drug benefit structures and strong mail-order pharmacy access. The SilverSneakers fitness benefit is included in many Cigna Medicare Advantage plans. Cigna has earned solid star ratings in several of its markets, particularly where it has invested in care management programs. Cigna's HMO plans in markets where they are established tend to have reasonable network depth. The company's behavioral health coverage and mental health integration are generally competitive.

Weaknesses

Cigna's Medicare Advantage geographic footprint is limited, and the company is not a national option in the same way UnitedHealthcare, Humana, or Aetna are. In markets where Cigna has limited penetration, provider networks may be thinner than established carriers. Prior authorization requirements exist for many services, consistent with industry practice. Cigna's Medicare customer service has received mixed reviews, with some markets performing better than others.

Plan types and what they offer

Cigna Achieve HMO plans typically offer zero or low premiums with SilverSneakers, dental, vision, and hearing benefits bundled in. Cigna's PPO plans offer out-of-network flexibility. Cigna also offers DSNP plans in select markets. Part D plans through Cigna often feature competitive tiering for Express Scripts-managed drugs and strong mail-order programs.

Star ratings history

Cigna's star ratings have generally been competitive in its core markets, with several plans earning four or more stars. The company's smaller scale allows more consistent quality management in its focused geographic markets compared to carriers managing much larger national footprints.

How big is Cigna, really?

The Cigna Group is a large company, with revenue as of 2024 running roughly in the range of $195 billion or more, much of that flowing through its sizable Express Scripts pharmacy arm rather than its insurance line. Medicare Advantage was always a smaller piece of Cigna, and here the distinctive fact overshadows the balance sheet, because in early 2024 Cigna agreed to sell its entire Medicare business, meaning its Medicare Advantage, Part D, and Medigap lines, to Health Care Service Corporation, or HCSC, for about $3.7 billion, a deal expected to close in 2025. In practical terms Cigna is effectively exiting Medicare Advantage, and existing members are transitioning to HCSC ownership. These figures are approximate, reflect where things stood as of 2024, and change every year, so read them as a general sense of scale.

What members actually say

Cigna's reputation has always been stronger on the pharmacy side, thanks to the Express Scripts integration, and members who take multiple medications often single out the mail-order program as a genuine plus. On the Medicare Advantage side sentiment was more muted, in part because MA was a smaller and more geographically focused line, so experiences varied by market with the usual industry frustrations around prior authorization. The bigger context now shaping member sentiment is the transition itself, since the plans are moving to HCSC, a large Blue Cross Blue Shield licensee. For anyone currently in a Cigna Medicare plan, the practical question is less about Cigna's old reputation and more about what the new HCSC-run version of the plan will look like.

The trend: is Cigna adding or cutting benefits?

Cigna is a special case, because rather than trimming benefits within Medicare Advantage it is leaving the MA business entirely, choosing to focus on its commercial and pharmacy operations while its Medicare book moves to HCSC. That said, the plans themselves still sat inside the same industry-wide squeeze that hit everyone for the 2025 and 2026 plan years, in which CMS rate changes, the phase-in of the v28 risk-adjustment model, and rising medical costs drove carriers to exit counties, cut dental, OTC, and flex allowances, raise out-of-pocket maximums, and narrow networks, with nearly two million members nationwide landing in discontinued plans. Because benefits and even ownership change during the Annual Enrollment Period, the only reliable way to know what a specific plan offers for the coming year is to compare the current-year details for your zip code, which a quick call can walk through with you.

Who Cigna tends to fit well

Cigna's plans often work well for enrollees in markets where the company has strong established networks, those who take multiple medications and want strong mail-order pharmacy programs through Express Scripts, and enrollees who value SilverSneakers gym access and behavioral health integration.
