OBSTETRIX MEDICAL GROUP OF ATLANTA, LLC is effectively a Medicaid-focused practice with no Medicare billing on file and $10M in lifetime Medicaid revenue; the absence of Medicare activity indicates this NPI functions principally within state Medicaid networks rather than serving a dual Medicare/Medicaid population. The provider was enumerated on 2009-05-22 (~17 years ago), indicating a long tenure in the market which supports relationship-building with payers and referral sources in Georgia. The provider’s revenue is highly concentrated in a small set of maternal–fetal service lines: the top 3 Medicaid codes (99214, 76819, 76816) together account for 49.8% of total Medicaid revenue, signaling that routine established-patient E/M visits and high-volume obstetric ultrasound services are primary revenue drivers. Code-level volumes and ranks show this entity is a major in-state provider for targeted obstetric imaging: 76819 ranks #3 of 41 providers (95th percentile) and 76816 ranks #3 of 55 providers (96th percentile), both described as notably above typical state volume, which implies specialized capacity or high demand for biophysical profiles and follow-up fetal ultrasounds. The practice also ranks highly for several other ultrasound and Doppler services — 76817 ranks #2 of 57 providers (98th percentile, labeled an extreme outlier) and 76820 ranks #2 of 24 providers (96th percentile, notably above typical state volume) — reinforcing that advanced fetal imaging and surveillance are core service lines and competitive strengths. Office E/M coding shows substantial activity at higher-level established-patient visits: 99214 generated $2M (20.1% of Medicaid revenue) with 29.2K claims and ranks #24 of 824 in-state (97th percentile), indicating heavy ambulatory throughput for established patients and a sizable role in ongoing prenatal care. Several specialized fetal echocardiography and Doppler codes (76825, 76827, 93325, 76821) contribute meaningfully to revenue and occupy high or leading state ranks (76827 is #1 of 5 providers, 76825 is #2 of 12 providers), suggesting the group offers subspecialty fetal cardiac imaging services that differentiate it within the Georgia Medicaid market. While many additional codes show typical or unremarkable volumes, the mix skews toward imaging and surveillance rather than inpatient or diverse multispecialty care (e.g., 99232 and other hospital care codes rank relatively low), indicating a focused outpatient maternal–fetal medicine practice model concentrated on prenatal diagnostics and management. Given the concentration in a few high-volume ultrasound and E/M codes, payers should view OBSTETRIX as a specialist clinic with predictable imaging-driven revenue and potential sensitivity to reimbursement changes for those key codes that together produce nearly half of its Medicaid revenue.
