Cornerstone Greenwood

Cornerstone Greenwood is a SAMHSA-registered addiction-treatment facility in Greenwood, SC. The facility's programming is outpatient (IOP, Dual Dx), not residential. This page frames the questions that matter most when evaluating a specific program — the ones that separate useful candidates from marginal ones.

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 is the benchmark framework for matching patients to appropriate intensity. Most major payer medical-necessity documents reference it. An outside ASAM-aligned assessment, prior to admission, is the protection against misplacement.

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. The operational prerequisite is written documentation: in-network status for your specific plan product, deductible accumulation, coinsurance rate, prior-authorization status. Admissions without these four documented carry material risk of post-admission financial disagreement.

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. Evaluating specialty capacity requires asking specifically: what clinicians deliver the specialty content, with what credentials, for how many hours per week. Marketing designation without documented clinical infrastructure is a recognized pattern worth filtering out.

Before you call

Three pre-admission questions for Cornerstone Greenwood: (1) at what ASAM 4e level are you admitting me, and what is the clinical rationale; (2) can you provide written Verification of Benefits for my specific plan; (3) what is your MAT policy for opioid use disorder — specifically, do you continue buprenorphine or methadone during residential programming. If the clinical situation involves opioid use disorder, confirm explicitly whether Cornerstone Greenwood offers medication-assisted treatment — buprenorphine, methadone, or naltrexone. Programs that do not are operating outside the current standard of care.
