    Payer Overview

    Delta Dental Plan of IL GRP operates as a focused dental insurer with a concentrated presence in the U.S. market. The company is the #145 ranked US A&H payer by premium, reporting $253.72M in US premium and a US market share of 0.02% across 8 states. It reports an estimated total membership of 36.6K and operates through 4 affiliated subsidiaries.

    Delta Dental Plan of IL GRP's largest concentration is in Illinois, where its premium footprint is most significant relative to other states. The payer does not hold a #1 position in any state. Its business is primarily within the continental US states reported and there is no recorded territory or foreign premium in the authoritative data.

    Premium & Market Share

    Premium by Scope

    Delta Dental Plan of IL GRP's premium is exclusively reported in the US States & DC scope with $253.72M written there, representing the entire reported premium. There is no recorded premium in US territories or in foreign jurisdictions, so the payer's revenue exposure is limited to the continental US states included in the filing. For providers, this concentration means network negotiation and reimbursement strategies should focus on state-level contracting where the payer has measurable footprint rather than on territory or international arrangements.

    National Market Presence

    Delta Dental Plan of IL GRP's footprint is highly concentrated in the Midwest, with $248M of premium written in Illinois alone. The national premium total of $253.72M is therefore dominated by a single state, which implies that network leverage and rate negotiations will be most impactful in Illinois. Outside Illinois, premiums per state are in the hundreds of thousands to low millions, so contracting strategies in those states should be localized and proportionate to the smaller membership bases.

    For national provider groups, the distribution suggests prioritizing negotiations and operational alignment in Illinois first, then selectively targeting North Carolina and Ohio where premium pools are larger than other non-Illinois states. The overall membership of 36.6K is modest, so broad multi-state contract rollouts should be weighed against the small member counts in most states.

    State-by-State Market Position

    Delta Dental Plan of IL GRP shows its strongest presence in the Midwest, led overwhelmingly by Illinois. The Midwestern concentration means the payer is most strategically important to provider organizations with a strong Illinois footprint. Secondary presence in the Southeast and Midwest (North Carolina and Ohio) is measurable but limited in scale compared with Illinois. This geographic profile favors targeted, state-level contracting approaches rather than a uniform multi-state network expansion strategy.

    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 (5,732 members), 35–44 (5,332 members), and 55–64 (5,198 members), indicating a strong presence among children, families, and older working adults. The smallest segments are the youngest (Under 6, 2,205 members) and oldest (75+, 2,078 members) age bands.

    Illinois dominates the member distribution, with 35,795 estimated members, far outpacing all other states. The age distribution in Illinois closely mirrors the national profile, with a strong presence in the 6–18, 35–44, and 55–64 bands. Other states have much smaller member counts, and their age distributions are proportionally similar, with no state showing a significant skew toward older or younger populations. This suggests a relatively uniform member profile across the payer's footprint, with the bulk of members concentrated in Illinois.

    Regional implications: the Northeast and West show effectively no reported premium for this payer, so national networks that depend on coast-to-coast parity will find limited value in this relationship. Multi-state provider groups with networks centered in Illinois can obtain the most leverage, while those focused in other regions should approach contracting selectively and consider the administrative cost versus member exposure when negotiating with this payer.

    Estimated Members by State

    DELTA DENTAL PLAN OF IL GRP's estimated member distribution is highly concentrated in Illinois, which accounts for 35,795 out of 36,611 total members nationally. The next largest states are North Carolina (315 members), Ohio (211 members), and Oklahoma (105 members), with the remaining states each having fewer than 100 members. This extreme concentration aligns with the payer's market share and premium volume, which are also overwhelmingly focused in Illinois.

    The geographic concentration of members means that providers in Illinois will encounter DELTA DENTAL PLAN OF IL GRP as a major payer, while those in other states will see only a minimal presence. For providers, this translates to a payer mix that is heavily influenced by DELTA DENTAL PLAN OF IL GRP in Illinois, with implications for contracting leverage, reimbursement rates, and care delivery strategies. In other states, the payer's footprint is negligible, and provider engagement will be limited to a small number of covered lives.
