Why 30 days is the default
Thirty days is not a clinical recommendation derived from outcome research — it's an insurance artifact. Most commercial PPO plans were designed around the 28-30 day inpatient block, which in turn aligns with the NY 28-day no-concurrent-review window. That practical floor has become the industry standard. For many presentations — first-time SUD treatment, moderate dependence, strong home support, uncomplicated clinical picture — 30 days is a reasonable dose of residential care. For severe long-term opioid use, polysubstance use with co-occurring psychiatric conditions, prior relapse history after shorter stays, or meth use disorder, 30 days is often not enough — and we'll say so during placement.
What a 30-day program typically includes
A representative 30-day OASAS-certified residential inpatient includes: 5–7 days of medical detox if clinically indicated, followed by 23–25 days of residential programming; individual therapy 2–3 times per week; daily group therapy (CBT, DBT, relapse prevention, trauma-focused as applicable); family therapy or family weekend programming; psychiatric evaluation and medication management; MAT initiation for opioid and alcohol use disorders where appropriate; aftercare planning including PHP/IOP step-down, sober living referrals if needed, and continuity with outpatient prescribers. Discharge planning starts at admission, not in the final week.
Extending beyond 30 days
Many inpatient programs build in clinically-reviewed extension options at day 21 — if the clinical team determines a longer stay is medically necessary, they work with the insurer to extend coverage. Post-day-28, concurrent utilization review is permitted under NY law, so extensions go through more scrutiny. In practice, clinically justified extensions to 45 or 60 days are common; the determining factor is documentation quality and medical-necessity standards. Our placement advisors ask during intake whether extended stay is likely to be clinically appropriate so we can match to a program with strong documentation infrastructure.
Frequently asked questions
Can I extend past 30 days?
Often yes, with clinical justification and insurer approval. After day 28 the plan can run concurrent review; a well-documented clinical case for extension is usually approved. The program's medical necessity documentation is decisive.
What if 30 days isn't enough?
For severe cases, 60 or 90-day programs exist and are covered by some plans. Step-down to PHP then IOP is the more common extended continuum. Sober living arrangements post-inpatient extend the environmental protection phase.
Is 30 days really enough for opioid use disorder?
For many, not as the sole intervention — but a strong 30-day inpatient with MAT initiation and a tight post-discharge MAT continuity plan can produce good outcomes. The post-discharge continuity matters more than the residential dose length for opioid use disorder specifically.
