SOUTHERN LAB PARTNERS, LLC is a clinical medical laboratory with an NPI enumerated 2012-10-18 (~14 years ago), indicating over a decade of presence in the market which supports an established laboratory operation and sustained payer relationships. Its Medicare lifetime revenue is $5.4M while Medicaid lifetime revenue is $14.4M, signaling a materially larger footprint in the Medicaid market versus Medicare. The provider’s Medicare revenue is highly concentrated: the precomputed top 3 Medicare codes account for 98.9% of its Medicare revenue, driven predominantly by K1034 which alone generates $5.2M (95.2% of Medicare revenue). That concentration implies a business model on Medicare that is overwhelmingly dependent on a single test-type activity. Medicaid billing is more diversified relative to Medicare but still concentrated: the precomputed top 3 Medicaid codes account for 62.8% of its Medicaid revenue, with large volumes in multiplex amplified probe and respiratory virus codes like 87798 ($4.2M, 29.7% of Medicaid revenue), 87633 ($3.4M, 24.0%) and 87801 ($1.3M, 9.2%), indicating a service line focused on high-volume infectious disease and respiratory pathogen testing for Medicaid payors. On competitive standing, SOUTHERN LAB PARTNERS is an extreme outlier nationally for K1034 (ranks #90 of 30143 providers nationally; 100th percentile), which signals unusually high Medicare volume for that code compared with peers; by contrast its other Medicare codes (G0482, G0480, etc.) are in typical-to-high percentiles but not exceptional. In the state Medicaid market the provider posts top-tier volumes for many infectious disease and multiplex testing codes: it ranks in the top decile or better for key codes (e.g., 87798 #6 of 57, 87633 #7 of 98, 87801 #6 of 92), and holds several #1 in-state ranks for specialized codes (e.g., 87149 and 87561 ranked #1 of small peer sets), consistent with a major regional player for molecular and multiplex infectious testing. The code mix (dominant K1034 on Medicare; high-volume amplified nucleic acid/multiplex codes on Medicaid such as 87798, 87633, 87801, and substantial U0004 and 87502 activity) indicates the lab operates high-throughput diagnostic and multiplex molecular platforms and likely focuses on respiratory and infectious disease panels rather than broad anatomic pathology or routine wellness testing. Given the extreme concentration in a single Medicare code versus a broader but still concentrated Medicaid profile, the provider’s financial exposure differs by payer: Medicare results could be vulnerable to reimbursement or coding shifts for K1034, while Medicaid revenue appears anchored in a portfolio of molecular panel services across many respiratory and infectious codes. Several Medicaid codes are flagged as “notably above typical” or top-ranked in-state (e.g., 87149 and 87561 at #1 in-state), reinforcing that the lab is a leading in-state provider for certain specialized molecular assays and likely competes at scale in state Medicaid contracting for infectious disease testing.
