Magna Ins Co Market Analysis: Market Share and Coverage by State

Payer Overview

Magna Ins Co operates as a modest regional commercial health insurer with a concentrated footprint and targeted market influence. It ranks as the #245 payer nationally and writes $9.21M in the US market, representing a 0 US market share across 2 states. The company reports an Estimated Total Members count of 1.4K and operates with 0 affiliated subsidiaries.

Magna Ins Co's presence is focused in a small number of states, which shapes its contracting leverage and network strategy. Because its premium is concentrated in just a couple of states, provider negotiation dynamics and reimbursement patterns will vary significantly compared with national carriers, and its operating scale is tightly linked to performance in those core states.

Premium by Scope

Magna Ins Co's premium is concentrated entirely within the US states and DC scope, with $9.21M reported in that category and no recorded premium in US territories or foreign operations. This indicates the payer's footprint is exclusively on the U.S. mainland and reflects a highly domestic business model.

For providers evaluating contracts, this concentration means network and reimbursement exposure will be confined to the payer's state markets. There is limited geographic diversification, so state-level performance and regulatory changes in those states will have an outsized impact on the payer's financials.

Magna Ins Co's premium is heavily concentrated in Tennessee, with $8.46M in written premium, while Mississippi represents a much smaller share at $753K. The insurer's total estimated membership is 1.4K, concentrated primarily in Tennessee (1.28K). This geographic concentration suggests that provider contracting power and network strategy will be most relevant in Tennessee, where the payer has the bulk of its commercial relationships.

Because the carrier's footprint covers only a couple of adjacent states in the Southeast, national provider groups should expect limited negotiating leverage with Magna Ins Co compared with larger multi-state payers. Local market dynamics in Tennessee will disproportionately affect Magna Ins Co's financial results and operational priorities.

State-by-State Market Position

Magna Ins Co shows its strongest presence in the Southeast region, led by Tennessee and followed by Mississippi. Tennessee is the top state by premium and membership, while Mississippi is a distant second. There are no material footprints in the Northeast, Midwest, West, or Southwest regions.

The concentration in the Southeast means multi-state provider groups with networks across the country will find limited scale exposure to this payer; conversely, regional health systems in Tennessee should treat Magna Ins Co as a meaningful local counterparty for contracting and reimbursement discussions. For providers considering expansion, the payer's narrow geographic distribution implies that efforts to negotiate standardized, multi-state arrangements with Magna Ins Co will have limited applicability outside its core states.

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.

Estimated Member Demographics

Nationally, the largest age bands for MAGNA INS CO are the 6–18 group (211 members), followed closely by the 55–64 (203 members), 45–54 (200 members), and 35–44 (195 members) bands. The pediatric (Under 6 and 6–18) and working-age adult (19–64) populations together make up the vast majority of the membership, while the senior (65+) population is relatively small at 192 members combined.

Tennessee, the state with the largest membership, mirrors the national age distribution, with a strong presence in the 6–18 and 35–64 age bands. Mississippi, with a much smaller member base, shows a similar pattern but with slightly higher proportional representation in the younger age bands. No state skews dramatically older or younger, but the overall member base is clearly weighted toward children and working-age adults.

Estimated Members by State

MAGNA INS CO's estimated membership is highly concentrated in Tennessee, which accounts for 1,280 of the 1,398 total members nationally. Mississippi is the only other state with a reported presence, with an estimated members. This distribution closely aligns with the premium volume and market share data, as Tennessee also represents the vast majority of premium written and the highest market share for the payer.
