Why are Medicare and Medicaid shown separately instead of combined?

They come from two different CMS data sources with no shared claim identifier, so they can't be reconciled into one number without double-counting or guessing. Every table and chart on this page keeps them fully separate.

Why is there no private/commercial revenue figure?

Private and commercial payer data comes from Transparency in Coverage files, which only publish negotiated rates — not claims or utilization volume. Without a volume figure, no revenue number can be computed for any provider from that data.

What does "Rank" mean in the Competitive Analysis & Benchmarks tables?

For a given CPT/HCPCS code, it's this provider's position by claims volume among all providers billing that same code at that geography level (State, National, or Tennessee for Medicaid) — rank 1 means the highest claims volume for that code.

Why is the Medicaid comparison limited to Tennessee only?

Medicaid is administered per-state with no single national fee schedule, so a state or national comparison the way Medicare has one isn't available. Tennessee (this provider's own state) is the only grouping that's conceptually meaningful.

Why are the numbers rounded to the nearest 10?

To avoid implying more precision than the underlying data supports at a single-provider level. Ratios are kept precise since they're a relative comparison, not a volume or dollar figure.

Key Findings

DEPARTMENT OF INTELLECTUAL AND DEVELOPMENTAL DISABILITIES, STATE OF TN is effectively a Medicaid-centric provider: it has no Medicare billing on file and reports $2.59B in lifetime Medicaid revenue. Its NPI was enumerated on 2016-02-10 (~10 years ago), indicating roughly a decade of identifiable billing activity under this registration.

Revenue is highly concentrated in a small set of waiver and habilitation codes: the top three Medicaid codes (T2033, T2021, T2016) account for 73.1% of the provider's total Medicaid revenue. Those codes individually contribute $1.53B (59.1%), $193.7M (7.5%), and $167.4M (6.5%) respectively, making T2033 by far the single largest revenue driver.

The code mix points to a large-scale residential and waiver services operation rather than traditional clinical or acute-care delivery: T2033 (Residential care, waiver; per diem), T2016 (Habilitation, residential, waiver; per diem) and multiple day habilitation and personal care codes (T2021, T2020, T1019) dominate the billing profile. This suggests the entity functions primarily as a statewide administrator/provider of long-term services and supports and day habilitation for individuals with intellectual and developmental disabilities.

Competitive standing within Tennessee is dominant for core service lines: the provider ranks #1 in-state and at the 100th percentile for T2033 (#1 of 97, extreme outlier), T2021 (#1 of 104, extreme outlier), and T2016 (#1 of 45, extreme outlier). These rankings reflect an outsized market share in residential and habilitation waiver services compared with other in-state providers.

Beyond the top three, the provider shows breadth across related waiver and support services with meaningful revenue in codes such as T1019 ($158.4M, 6.1%), T2020 ($143.3M, 5.5%), and T2012 ($135.4M, 5.2%), plus employment supports H2025 ($85.9M, 3.3%) and monthly case management T2022 ($78.5M, 3.0%). This spread indicates a vertically integrated service footprint covering personal care, day habilitation, residential habilitation, employment supports, and case management rather than a narrow specialty practice.

Multiple non-residential therapy and ancillary codes also appear as state outliers: G0153, G0151, G0152, T2002 and dental codes like D4341 all rank at or near #1 in-state and are labeled as extreme outliers or notably above typical state volume. That pattern signals the provider is the primary in-state biller for many specialized therapy, transportation, and dental services tied to waiver populations.

From a payer perspective, the dominance of per-diem and per-15-minute waiver codes (e.g., $1.53B on T2033 and large volumes on T2021 and T2016) implies utilization and cost exposure are concentrated in predictable service categories and units of service. Given the scale on a handful of codes, payers negotiating rates, defining covered service modalities, or managing network adequacy should treat this entity as a system-level counterparty for Tennessee waiver populations.

For monitoring and contracting strategy, the combination of a single-payer (Medicaid-only) revenue base of $2.59B, very high concentration in waiver codes (73.1% from the top three), and an NPI tenure of ~10 years suggests an established operator with major influence on in-state capacity for I/DD services. Analysts should prioritize engagement and capacity review for residential, day habilitation, and case management lines when assessing network sufficiency and program-level financial risk.
