Want a calm next step?

If you’re overwhelmed, you don’t need the perfect plan today. A short call can help you understand the safest level of care and what to do next.

If there is immediate danger, severe withdrawal, or risk of self-harm/violence, call 911 or go to the nearest ER. Otherwise, a confidential admissions call is a calm first step.

What do “levels of care” mean, and how do they compare?

Levels of care are different amounts of support. The goal is safety + structure, then a step-down plan.

Detox

Best for: withdrawal risk and physical stabilization

Main goal: safety + comfort + next-step plan

Residential (RTC)

Best for: triggers at home, relapse risk, unstable mental health

Main goal: 24/7 structure + therapy + routine

PHP / IOP

Best for: step-down support while rebuilding independence

Main goal: structure + skills + accountability

FAQ: Rehab and mental health terms families ask about most

These are simple answers to common questions families ask when they’re learning rehab language.

What’s the difference between detox and residential treatment?

Detox is about withdrawal safety and physical stabilization. Residential is about structured therapy, routine, and relapse prevention after the body stabilizes.

What do “levels of care” mean?

Levels of care are different amounts of support. Detox is the highest safety support for withdrawal. Residential is 24/7 structure and therapy. PHP is high-support day treatment. IOP is structured therapy multiple days per week while living daily life.

What does “dual diagnosis” mean?

Dual diagnosis means substance use and mental health symptoms happen at the same time (like anxiety, depression, PTSD, bipolar). Treatment works best when both are addressed together.

Why can’t staff talk to me without a Release of Information (ROI)?

Privacy laws protect the client’s health information. A signed ROI is how the client chooses who can receive updates or participate in care planning.

What’s the difference between a slip (lapse) and relapse?

A slip/lapse is usually a brief return to use. Relapse often means a return to old patterns. Both are signals to respond quickly with support, not shame.

What does “prior authorization” mean?

Prior authorization means insurance wants clinical approval before they agree to cover a service. This is common for residential and PHP.

What should I ask on the first call with admissions?
  • What level of care do you recommend and why?
  • What does the first 24 hours and first week look like?
  • How do you support withdrawal risk and cravings?
  • How do you support mental health symptoms (anxiety, depression, trauma)?
  • What family support is available?
  • What is the step-down plan after stabilization?

Safety note: If there is immediate danger, severe withdrawal, or risk of self-harm/violence, call 911 or go to the nearest ER.
