    Payer Overview

    Health One Alliance Group operates as a mid-ranked national A&H payer, positioned as the #121 largest US A&H payer by premium. The company reports $417.82M in US premium and holds a 0.03% US market share, operating across 2 states. The organization serves an estimated 69.4K members and operates through 2 affiliated subsidiaries, reflecting a compact national footprint focused on select regional markets.

    The payer's concentrated premium and membership base is heavily weighted toward a single state, which shapes its negotiating leverage and provider network priorities. Because its presence is limited to 2 states, Health One Alliance Group will likely prioritize contracting and reimbursement strategies that reinforce local provider partnerships rather than pursuing broad national network integration.

    Premium & Market Share

    Premium by Scope

    Health One Alliance Group's premium is entirely concentrated in the US States & DC scope, with $417.82M reported in that bucket and 100.00% of the payer's premium attributable to US states. There is no reported premium in US territories or foreign jurisdictions.

    This exclusive U.S. mainland footprint implies that provider groups evaluating this payer should focus on its state-level market dynamics and local negotiation posture. National contracting platforms or international considerations are not relevant for this payer given the absence of territory or foreign premium.

    National Market Presence

    National Market Footprint

    Health One Alliance Group's national footprint is highly concentrated in the Southeast, with $412.14M of premium and roughly 68.6K members located in GA. The remaining exposure is minimal, with $5.68M and about 860 members in TN, bringing the total to $417.82M and 69.4K members. This concentration in a single state elevates the payer's local negotiating influence in Georgia while limiting cross-state network scale.

    For provider contracting nationally, the implications are straightforward: meaningful leverage and utilization patterns will be driven by the Georgia relationship. Multi-state provider groups should prioritize contracting terms and operational alignment in Georgia to capture the majority of this payer's business, while Tennessee represents a much smaller opportunity.

    State-by-State Market Position

    Health One Alliance Group's presence is concentrated in the Southeast region, with Georgia as the clear focal point and Tennessee providing a very small supplementary presence. The strongest state is GA, which holds the payer's dominant premium and member base, while TN appears to be a marginal market.

    This distribution means regional provider systems centered in the Southeast, particularly those with scale in Georgia, will find the most negotiation relevance with this payer. Multi-state provider groups that do not operate meaningfully in Georgia will find limited leverage given the payer's narrow geographic reach.

    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

    Nationally, the largest age bands are 6–18 (10,971 members), 45–54 (10,523 members), and 35–44 (10,287 members), indicating a strong presence among school-aged children and working-age adults. The smallest age bands are 75+ (3,284 members) and Under 6 (4,052 members), suggesting a relatively lower senior and early childhood population.

    Georgia, the dominant state, closely mirrors the national profile, while Tennessee, with only 860 estimated members, has a similar age distribution but at much lower volume. No state shows a significant skew toward older or younger populations; the age mix is consistent across both states.

    The geographic concentration in Georgia means that providers in this state are most likely to encounter HEALTH ONE ALLIANCE GRP members, especially in pediatric and adult primary care settings. For providers in Tennessee, the payer's presence is negligible, and contracting opportunities are limited. This distribution aligns closely with the payer's premium and market share data, reinforcing Georgia as the primary market for provider engagement and care delivery strategies.
