STONINGTON BEHAVIORAL HEALTH INC is effectively a Medicaid-focused psychiatric hospital: there is no Medicare billing on file while reported Medicaid revenue totals $51M, indicating the provider operates almost entirely within the state Medicaid market rather than as a dual-payer provider. The organization’s NPI was enumerated ~20 years ago (2006-03-20), showing long tenure in the market which may support established referral relationships and service capacity. The provider’s Medicaid revenue is highly concentrated in three procedure lines: H0015, H2013, and H0011 together account for 97.5% of its total Medicaid revenue, signaling a narrow service mix centered on behavioral health and substance use treatment rather than broad outpatient medical care. H0015 (intensive outpatient substance use services) is the largest single revenue driver at $29M and represents 56.9% of this provider’s Medicaid revenue; the provider ranks #1 of 74 in-state for H0015 and is described as an extreme outlier, indicating dominant statewide volume for intensive outpatient addiction treatment. H2013 (psychiatric health facility per diem) contributes $11.7M or 22.9% of Medicaid revenue and ranks #1 of 6 in-state for that code, reflecting substantial inpatient/residential psychiatric capacity relative to peers and a competitive position among facilities that bill per diem psychiatric services. H0011 (acute detoxification residential addiction program) contributes $9M or 17.7% of Medicaid revenue and ranks #1 of 7 in-state, a placement described as typical for that code but still confirming that residential detox is a material part of the provider’s business. Routine evaluation-and-management office codes (for example 99213, 99204 and smaller volumes of 99202/99212/99214/99203) together represent only a small share of Medicaid revenue (individual revenues listed range from $30.5K to $730.3K), indicating that outpatient E/M visits are minor components of overall billing compared with intensive substance use and psychiatric facility services. Several ancillary mental health codes show negligible or zero payment ($0 reported for H0047 and H0035 in the dataset), suggesting either non-reimbursed reporting, alternative funding streams, or low-volume activity for those specific program codes within this provider’s mix rather than material revenue sources.
