    Key Findings

    HAFA ADAL SPECIALIST GROUP, LLP is coded as an Ambulatory Surgical Clinic/Center and its Medicare claims mix is concentrated in GI endoscopy and colorectal screening procedures. The visible top procedures are G0121, 43239, 45380 and 45385, which correspond to colorectal cancer screening/colonoscopy, upper endoscopy with biopsy, colonoscopy with biopsy, and colonoscopic lesion removal — a profile consistent with a small outpatient endoscopy-focused operation.

    Revenue concentration is high: the precomputed top 3 Medicare codes account for 87.4% of this provider's total Medicare revenue, with G0121 alone generating $22.5K (44.0% of Medicare revenue), 43239 generating $13.5K (26.5%), and 45380 generating $8.6K (16.9%). This level of concentration signals that changes to utilization patterns or reimbursement for these specific services would materially affect the practice's Medicare revenue.

    Scale and payer mix are narrow: total Medicare revenue on file is $51K and there is no Medicaid billing on file, so the provider is effectively single-payer from the dataset’s perspective. The absence of Medicaid activity limits exposure to state program volume but also suggests constrained participation in or access to the Medicaid patient population.

    Competitive standing on the leading screening code is relatively elevated but described as typical: G0121 ranks #980 of 7750 providers nationally (87th percentile; typical, unremarkable volume for this code). In context of the practice’s small absolute Medicare revenue ($51K), this suggests the provider achieves a comparatively stronger position on this screening code than on other services, but is not a dominant national player.

    The provider’s national standing for upper endoscopy with biopsy is mid-range: 43239 ranks #9496 of 17140 providers nationally (44th percentile; typical, unremarkable volume for this code). This percentile and the $255 avg paid/claim indicate routine participation in diagnostic upper endoscopy among peers rather than concentrated specialty dominance.

    For therapeutic colonoscopy activity the provider is a low-volume participant: 45380 ranks #13231 of 16427 providers nationally (18th percentile; typical, unremarkable volume for this code) and 45385 ranks #14738 of 16310 providers nationally (8th percentile; typical, unremarkable volume for this code). Those lower percentiles imply relatively limited experience or throughput in excisional polypectomy and other advanced colonoscopic interventions compared with national peers.

    Payment per claim varies by service: reported avg paid/claim values run from $255 for 43239 up to $431 for 45380 and $427 for 45385, with G0121 at $416 avg paid/claim. This spread suggests higher per-claim reimbursement for colonoscopy procedures that include biopsy or lesion removal compared with diagnostic upper endoscopy, consistent with the differing intensity of those services.

    The provider has long tenure in the NPI registry (NPI enumerated 2009-10-08 (~17 years ago)), indicating an established practice footprint. Despite long registration, the modest lifetime Medicare revenue ($51K) and lack of Medicaid billing on file suggest this entity operates at a relatively small scale or serves a limited Medicare panel compared with typical ambulatory surgical centers.
