This provider effectively operates as a Medicaid-focused hospital: there is no Medicare billing on file and total Medicaid revenue is $52.4M, so its commercial/Medicare exposure is minimal or absent in the available claims data. Analysts should treat CHATTANOOGA HAMILTON COUNTY HOSPITAL AUTHORITY as a single‑payer (Medicaid) incumbent for the purposes of Medicaid network and rate analysis.
Revenue is highly concentrated in emergency department evaluation & management services: the top three Medicaid codes (99284, 99283, 99285) together account for 69.5% of the provider's Medicaid revenue. Individually those codes are $13.9M (99284, 28.8%), $13.5M (99283, 27.9%), and $6.2M (99285, 12.8%), which indicates the ED is the primary revenue driver for this facility.
The code mix and high share from ED E/M codes imply an operational focus on acute emergency care and associated throughput: frequent moderate- and low-complexity ED visits (99284 and 99283) dominate billing, with a meaningful tail of high-complexity ED/critical care (99285 and 99291) and hospital observation (G0378) services that support downstream admission or extended ED management. This pattern is consistent with a general acute care hospital acting as a regional ED hub.
Competitive standing within Tennessee is strong for several ED-related codes: 99283 ranks #11 of 611 providers in-state (98th percentile, described as notably above typical state volume), 99284 ranks #17 of 625 (97th percentile, typical/unremarkable volume), and 99285 ranks #30 of 565 (95th percentile, typical/unremarkable volume). These rank/percentile signals position the hospital as a major ED participant statewide, particularly for lower- and moderate-complexity visits.
There are pronounced statistical outliers in select service lines that warrant operational review: 99282 is an extreme outlier (rank #2 of 184, 99th percentile) despite representing $2.5M (5.2%) of Medicaid revenue, and 96361 (additional-hour IV fluids) is a 100th‑percentile extreme outlier (rank #1 of 105). The combination suggests unusually high volumes of brief, low-complexity ED encounters plus sustained IV-fluid administration relative to in-state peers.
Laboratory and ancillary services also contribute meaningfully and reflect broad inpatient/ED capability: high-volume lab and infectious-disease testing codes such as 96374, 87635, U0003, 87502, 87633, and 87651 appear in the top 25 list, while procedural codes like 69436 (tympanostomy), 43239 (upper endoscopy with biopsy), and imaging/echo codes (71046, 93304, 93325) demonstrate that the facility bills across surgical, endoscopic, and diagnostic lines beyond ED throughput. This mix supports a full-service hospital profile rather than a freestanding ED.
Several rank-1 and top-percentile lab/procedure codes point to specialized testing or throughput concentration: 87076 (additional anaerobic isolate testing) is rank #1 of 6 (100th percentile) and 96361 is rank #1 of 105 (100th percentile). These concentrated high-volume ranks indicate the provider performs certain laboratory and infusion services at levels well above most in-state peers, which could affect contract pricing and utilization management for those service lines.
The provider has an established NPI tenure (enumerated on 2006-10-04, ~20 years ago), indicating long-standing operations in the market. Combined with the Medicaid-only billing footprint and the ED-dominant revenue profile, this tenure suggests the hospital is a persistent regional resource for Medicaid populations and should be assessed accordingly during network strategy and payer negotiations.
