Payer Overview
Signature Advantage LLC is a modest regional health insurer with a focused footprint in the U.S. healthcare market. As the #218 ranked US A&H payer, it reports $37.2M in US premium and holds a US market share of 0% while operating in 2 states. The company serves an estimated 4.6K members and does not operate through any affiliated subsidiaries (Subsidiary Count: 0).
Signature Advantage LLC's position is concentrated in a small number of states rather than spread nationally. It does not hold a #1 ranking in any state. This concentrated profile shapes its negotiating leverage with providers and makes its contracting strategy highly regional and relationships-driven.
Subsidiary Filings
National Market Presence
Signature Advantage LLC's premium is concentrated in the Southeast, with $28.6M reported in KY and $8.59M in TN, totaling $37.2M across the footprint. The carrier serves about 4.6K members, a scale that supports focused regional network negotiations rather than national contracting programs. For provider contracting, this concentration suggests opportunities to build deeper, localized partnerships in Kentucky and Tennessee where the payer's membership and premium are concentrated.

State-by-State Market Position
Signature Advantage LLC's strongest presence is in the Southeast region, anchored by Kentucky and Tennessee. Kentucky is the primary state with $28.6M in premium and the largest estimated membership of 3.27K, while Tennessee contributes $8.59M and about 1.30K members. There are no top-ranked (#1) states for the payer.
For multi-state provider groups, the payer's geographic distribution implies that network strategy should prioritize Kentucky first, then Tennessee. The regional concentration simplifies operational coordination but limits bargaining leverage compared with national payers; providers should negotiate value-based arrangements that reflect the payer's localized membership and premium levels.
About ACA Marketplace Data
The Affordable Care Act (ACA) established federally-facilitated health insurance marketplaces ("exchanges") where individuals and small businesses can shop for and enroll in health plans, often with income-based subsidies. Issuers that participate in these marketplaces are required to report enrollment, claims, and denial data to CMS (Centers for Medicare & Medicaid Services) each year.
The sections below cover this payer's ACA marketplace-specific footprint — enrollment, plan portfolio, and claims/denial-rate data. This is a narrower, separate population from the NAIC-based commercial data shown earlier on this page (total premium, market share, and membership across all lines of business): ACA marketplace enrollment is typically a small fraction of a payer's total commercial book, and the two datasets should not be treated as equivalent. CMS claims-transparency reporting has also been inconsistent industry-wide since 2020 — many issuers have little or no data for 2021 onward, so a single reporting year is common and does not necessarily indicate anything about the payer's current ACA presence.
Member Demographics
Estimated Member Demographics
The largest age bands nationally are 55–64, 45–54, and 35–44, each with over 600 members. Pediatric populations (Under 6 and 6–18) together account for nearly 1,000 members, indicating a significant need for child and adolescent health services. The senior population (65–74 and 75+) is smaller but still notable, with over 680 members combined.
Kentucky has a slightly older profile, with higher counts in the 55–64, 65–74, and 75+ bands compared to Tennessee. Tennessee's member distribution is more balanced across age bands, but with fewer seniors. Providers should note these differences when planning care delivery and resource allocation.

Estimated Members by State
SIGNATURE ADVANTAGE LLC's estimated member distribution is concentrated in Kentucky (3,270 members) and Tennessee (1,299 members). Kentucky accounts for the majority of the payer's insured population, aligning with its higher premium volume and market share. Tennessee, while having a lower market share and premium, still represents a significant member base.
