    Key Findings

    The CITY OF LOS ANGELES is operating as an ambulance service (taxonomy: Ambulance) with an NPI enumerated ~20 years ago (2006-11-21), indicating long tenure in Medicare/Medicaid billing and an established emergency transport operation. The dominant CPT/HCPCS codes billed are ambulance-specific (A0427, A0429, A0425), consistent with a core business of emergency advanced life support and basic life support ground transports and mileage reimbursement.

    Revenue is heavily concentrated in a very small set of procedure codes for both payers: the precomputed top 3 Medicare codes account for 98.6% of this provider's total Medicare revenue, while the precomputed top 3 Medicaid codes account for 99.3% of total Medicaid revenue. This concentration implies the provider’s financial profile is highly dependent on emergency ambulance transports and associated mileage.

    On scale, the provider’s Medicaid revenue ($134.7M) substantially exceeds its Medicare revenue ($17.9M), indicating that Medicaid is the principal payer by dollars received; the operation is effectively Medicaid-dominant in absolute revenue terms. Analysts should therefore treat Medicaid trends and reimbursement changes as the primary driver of this entity’s financial performance.

    For Medicare, A0427 (ALS 1 emergency) is the single largest driver: 28.3K claims generating $12.8M and representing 71.5% of the provider’s Medicare revenue, and the provider ranks #3 of 6841 nationally (100th percentile, extreme outlier). This national ranking and percentile position indicate the provider is an exceptionally large Medicare ALS 1 emergency transport provider compared with peers.

    For Medicaid, A0427 and A0429 together dominate: A0427 accounts for $76.2M (56.6% of Medicaid revenue) and A0429 accounts for $53.7M (39.9% of Medicaid revenue), with the provider ranking #2 in-state for both codes (100th percentile, extreme outlier). This places the provider as a dominant statewide player for both ALS 1 and BLS emergency ground transports, with those two codes making up the vast majority of Medicaid billings.

    Mileage (A0425) contributes meaningfully to both payers but at a much smaller share of revenue: it represents 5.3% of Medicare revenue and 2.9% of Medicaid revenue, and the provider ranks highly (Medicare rank #83 of 8934, Medicaid rank #3 of 580). These patterns are consistent with high-volume ground transport activity where mileage billing is routine but not the primary revenue driver.

    Additional high-acuity services are present but represent a small percentage of revenue: A0433 (ALS 2) is a minor revenue contributor on both payers (1.4% of Medicare revenue and 0.7% of Medicaid revenue) yet ranks as an outlier in volume (Medicare rank #9 of 1632; Medicaid rank #1 of 39 in-state). That combination suggests the provider occasionally bills higher-level advanced life support interventions but does so at volumes that are large relative to most peers.

    Given the extreme outlier rankings across multiple top codes (100th percentile for A0427 and A0429 nationally/in-state and very high national ranks for A0425 and A0433), the provider should be classified competitively as a major, high-volume municipal ambulance operator relative to both national Medicare and California Medicaid peers. Operational and contract analysts evaluating network adequacy or rate-setting should treat this entity as a central ambulance service with outsized local market impact.
