HEESOO KO is effectively a Medicaid-focused pediatric dentistry provider with no Medicare billing on file and $264.9K in lifetime Medicaid revenue, indicating a single-payer footprint concentrated in state Medicaid rather than Medicare. The provider has been NPI-enumerated since 2007-03-08 (~19 years), signalling long-term local presence that aligns with steady Medicaid billing over time. Revenue concentration is meaningful: the top three Medicaid codes by revenue account for 50.7% of total Medicaid revenue, showing that a small set of services generates half of the providers Medicaid income. The single largest revenue driver is D4341 (periodontal scaling and root planing - four or more teeth per quadrant) with $50.8K (19.2% of Medicaid revenue) and 350 claims; this code ranks #1 of 4 providers in-state (100th percentile), indicating the provider is a leading in-state source for multi-quadrant periodontal therapy within the pediatric dentistry taxonomy. D2930 is the second-largest code line with $49.4K (18.7% of revenue) across 321 claims and ranks #6 of 7 providers in-state (17th percentile), which suggests typical in-state competition for that procedure rather than dominance. High-dollar, lower-volume procedures such as D9221 ($34.1K, 68 claims; 12.9% of revenue) and D9220 ($13.9K, 68 claims; 5.3% of revenue) appear in the top revenue mix; both are sole-reporting in-state (rank #1 of 1) meaning there are no direct state peers for these specific codes, positioning the provider as the only Medicaid biller for those services in the available state dataset. Routine pediatric preventive and diagnostic codes (for example D1120 prophylaxis–child at $21.9K and D0150 comprehensive evaluation at $17.2K) together represent a material portion of billing, implying the practice manages a mix of preventive care alongside higher-revenue periodontal and operative services. Across its top codes most rank in low-to-mid percentiles among in-state peers (many described as "typical, unremarkable volume"), so while HEESOO KO is a notable local provider for specific services like D4341 and unique reporters for D9221/D9220, its overall competitive standing is more modest across the broader set of common pediatric dental procedures.
