    Key Findings

    Payer mix and scale: This facility reports $2.8M in total Medicare revenue and $3.4M in total Medicaid revenue, indicating it bills both programs at comparable scale rather than being effectively single-payer. Both payers contribute material revenue streams to the operation, with Medicaid slightly larger in lifetime revenue.

    Medicare revenue concentration: The top 3 Medicare codes by revenue account for 57.9% of this provider's total Medicare revenue, driven by 45385 ($656K, 23.7%), 45380 ($605.1K, 21.9%), and 43239 ($340.1K, 12.3%). This concentration shows a heavy dependence on a small set of endoscopic procedures for Medicare revenue.

    Medicaid revenue concentration: The top 3 Medicaid codes by revenue account for 88.3% of this provider's total Medicaid revenue, concentrated in 43239 ($1.6M, 48.0%), 45380 ($1.1M, 31.4%), and 45385 ($297.3K, 8.9%). Medicaid billing is extremely concentrated in a few high-volume endoscopic codes, with nearly half of Medicaid revenue coming from a single code, 43239.

    Business/service-line implications: The code mix — dominated by 45385, 45380, and 43239 across payers — is consistent with an endoscopy center focused on high-volume diagnostic and therapeutic gastrointestinal procedures (colonoscopies with polypectomy/biopsy and upper endoscopies with biopsy). The presence of screening-specific codes such as G0105 and G0121 on the Medicare side further indicates significant preventive and screening colonoscopy activity alongside diagnostic and therapeutic work.

    Competitive standing — Medicare (national): For several of the top Medicare codes the provider ranks at the extreme top nationally (45385 rank #8 of 16310, 45380 rank #4 of 16427, 43239 rank #6 of 17140; all 100th percentile and labeled "extreme outlier"). These rankings indicate volumes far above typical national providers for the same CPTs and suggest this entity is a national outlier in colonoscopy/EGD throughput for Medicare.

    Competitive standing — Medicaid (state): The provider is a statewide leader on key Medicaid codes: 43239 and 45380 both rank #1 in-state (100th percentile), and 45378 and 43248 also rank #1 in-state. Those in-state #1 ranks and “extreme outlier”/“notably above typical” labels show the center is a dominant Medicaid billing presence in Mississippi for core endoscopy services.

    Notable ancillary services and variability: Medicare billing includes a non-GI procedure 64561 with $254K revenue and a high average paid/claim ($3528), ranked #54 of 564 (90th percentile), signaling the facility also bills some specialized interventional pain/neuromodulation work in addition to core endoscopy. The coexistence of high-volume diagnostic/therapeutic GI codes with occasional higher-reimbursement, lower-volume procedures suggests a mixed service portfolio.

    Tenure and operational stability: The provider’s NPI was enumerated on 2007-04-06 (~19 years ago), indicating a long-established presence in the market; combined with the consistently high volumes and rankings across both payers, this suggests sustained operational scale rather than a recent surge in activity.
