DEEP DIVE 📚
C-SNP Continues to Surge in 2025 🚀
Last week our deep dive gave an update on D-SNP enrollments (read it here).
While D-SNP growth has cooled, the C-SNP market is growing fast - rapidly expanding access for beneficiaries with complex chronic needs and reshaping the competitive MA landscape.
(Note: Chronic Condition Special Needs Plans (C-SNPs) serve Medicare beneficiaries with qualifying chronic conditions like diabetes, cardiovascular disorders, and certain autoimmune diseases — an often underserved segment of the MA market.)
So far in 2025, the D-SNP market has grown 2.4% (Dec. ‘24 - July ‘25), down from 5.2% last year (Dec. ‘23 - July ‘24), and 19.4% the prior year (Dec. ‘22 - July ‘23).
At the same time, the C-SNP market has grown 48% (Dec. ‘24 - July ‘25), up from 41% last year (Dec. ‘23 - July ‘24), and 16.5% the prior year (Dec. ‘22 - July ‘23).

You can see the large increase in enrollment during AEP, and then the continued surge throughout 2025.

Where did the C-SNP Growth Happen?
C-SNP By State
First of all, not every state has C-SNP enrollment. In the map below, the grey states have no recorded enrollment.
(Note: CMS data excludes counties with fewer than 11 enrollees, so some states may have small but unreported enrollment.)

Below is the C-SNP enrollment growth from Dec. 2024 to July 2025.

Source: data pulled from MMI+ MA Web App
Key Insights:
Large MA states (Florida, Texas and California) continue to lead the market in C-SNP enrollment and have all seen impressive growth in 2025
Opportunities? New York, Pennsylvania, Ohio and Michigan. Large MA populations with minimal C-SNP enrollment, suggesting untapped market potential. This is true even after seeing explosive growth so far in 2025.
C-SNP Penetration Rate: Nationwide penetration has grown to 4.4%, and Arkansas reached 14%, showing the high potential.
💥 If all states were at 14%, the C-SNP market would be 4 million (nearly 4x current)!

Carrier Level C-SNP Trends
UnitedHealth Group has dominated C-SNP enrollment growth in 2025. But several smaller regional carriers also stand out.

Key Insights:
United led growth and has been the clear leader in expanding C-SNP nationwide.
Humana and Elevance round out the top 3 but have grown slower than the overall C-SNP market.
Alignment, SCAN, Zing, Avian and Sentara all grew at a faster rate than the overall market.

Final Observations
While United has dominated the C-SNP growth, it’s worth mentioning that each state is it’s own unique market.
There are some C-SNP State markets that still only have one Carrier with enrollment.
→ 13 states only have one Carrier with Enrollment
For Example:
AL → 30,000 C-SNP enrollees; 100% UnitedHealth Group
UT → 14,500 C-SNP enrollees; 100% UnitedHealth Group
NJ → 300 C-SNP enrollees; 100% Elevance
Note: In most of the 13 states, United is the only Carrier with enrollment
Other states where there are a number of Carriers, but 1 dominates…
For Example:
TX → 174,000 C-SNP enrollees; 81% United, 14% Humana, 2% Elevance
TN → 36,000 C-SNP enrollees; 88% United, 8% Humana, 3% Zing

source: MMI+ MA Web App
And a few “mature” markets where there are a number of Carriers with significant share…
For Example:
CA → 141,000 C-SNP enrollees; 29% Alignment, 21% SCAN, 14% Molina, 13% United
FL → 225,000 C-SNP enrollees; 49% Elevance; 34% Humana, 13% UnitedHealth

The C-SNP market continues to expand much faster than the overall Medicare Advantage market.
With only 4.4% penetration nationwide, C-SNPs remain one of the least saturated — but fastest-growing — opportunities in Medicare Advantage.
Expect this segment to be a key battleground heading into 2026.
SPONSOR SNAPSHOT 🚀: Telos Actuarial
The Medicare program currently serves 67.6 million beneficiaries with that number expected to grow to 80.5 million by 2034. Medicare supplement insurance will continue to be a popular option for a significant portion of these beneficiaries in providing health insurance benefits.
After several years of sizable decreases in Medicare Supplement enrollments, the decline slowed in 2024. It is projected that enrollments will return to grow in future years, creating robust opportunities in the Medicare Supplement market.
