Care levels at Cornerstone Greenwood

Cornerstone Greenwood is an outpatient-focused program (IOP, Dual Dx) — patients live at home or in sober living and attend treatment sessions. This level of care is clinically appropriate for mild-to-moderate substance use disorder, or for patients stepping down from residential. ASAM Criteria 4e level-of-care matching requires clinical assessment across six dimensions (withdrawal potential, biomedical conditions, emotional/behavioral/cognitive conditions, readiness, relapse risk, recovery environment). The alignment of Cornerstone Greenwood's offerings to any specific patient's clinical profile should be determined by an independent ASAM-aligned assessment prior to admission.

Insurance and payment

Cornerstone Greenwood accepts both Medicaid and commercial insurance, which is the broadest payer profile and typically correlates with programs that operate at scale across the economic spectrum. Benefit verification should be obtained in writing prior to admission and should document: network contract status for the specific insurance product, prior authorization requirements and approved day-count, applicable cost-sharing structure, and out-of-network secondary coverage (where applicable). Proceeding on verbal VOB creates material risk of post-admission benefit dispute.

Specialty programming

The facility's documented specialty programming includes: Adolescents, Criminal justice (other than DUI/DWI)/Forensic clients, Clients with co-occurring mental and substance use disorders. Clinical verification of specialty programming should encompass credentialed staff profile, programming-hour documentation, and specialty-specific medical-necessity documentation for third-party authorization. The MHPAEA 2024 rule addresses specialty-program network adequacy for patients requiring specific clinical capabilities.
