Grata Health co-treats opioid and alcohol use disorder alongside your clinicians — prescribing, medication management, and SUD-specific support, 100% virtual, covered by insurance including Medicaid. Your patients stay in your care.
The referral gap
MAT prescribing isn't your model
They chose virtual care for a reason
Waitlists — and few take Medicaid
Progress stalls on everything else
Our promise to referring partners
Fast response, right-fit care, and closed-loop updates for every patient you trust us with.
Every referral is acknowledged by a live member of our care team almost immediately — by phone, text, or email — so your patient is never left in a queue.
Why Grata
We prescribe and manage the medication side — buprenorphine, naltrexone, SUD-specific support — while your clinicians keep doing what's working. Your patients stay in your care.
Same-day
Most appointments
Patients meet their treating clinician. Medication can be prescribed at the visit when clinically appropriate.
1–2 days
Medication delivery
Delivery takes 1–2 business days from prescribing. First prescriptions and refills are eligible, with shipping covered. Local pickup is also available.
7 days
Support each week
Support is available 6 a.m.–11 p.m. Eastern. We help with scheduling, coverage, technology, and pharmacy access.

Virtual therapy and psychiatry practices, virtual IOPs, dietitian and chronic-care providers, coaching and EAP teams — clinicians who encounter opioid or alcohol use in their caseload but don't prescribe MAT.
No. Your clinician keeps the relationship and the treatment plan. We add the addiction medicine layer — prescribing, medication management, SUD-specific support — and coordinate with your team rather than duplicating it. Patients stay in your care.
A shared link or the two-minute form at partner.grata-health.com — no contract, no integration. Your clinician can set it up during a session. We reach out to the patient, verify coverage, and hold the first visit when available; most appointments are same-day.
Yes — Medicaid (Cardinal Care, Ohio Medicaid, Pennsylvania Medicaid) and major commercial plans across Virginia, Ohio, and Pennsylvania, verified before the first visit. If a patient is outside our footprint, we tell you fast rather than sit on the referral.
Yes. Our DEA-registered physicians, nurse practitioners, and physician assistants prescribe buprenorphine and naltrexone via telehealth under current federal and state rules — by phone or video, with no in-person visit required.
With patient consent, we send progress updates back to the referring clinician — medication changes, engagement, clinical flags — by secure message, fax, or email. Substance use treatment shouldn't be a black box in the middle of your care plan.
