What happens during admission:
step by step
Walking into treatment for the first time is easier when you know what to expect. This guide covers every step from first contact with a program through your first 72 hours, so there are no surprises on the day you arrive.
Before admission: what happens first
The admission process begins before you ever walk through a facility’s door. For most people, it starts with a phone call to a treatment program’s admissions line. What follows is a series of steps that happen in a predictable order, though the timeline varies by program and by whether TRICARE prior authorization is needed.
Understanding these steps helps you prepare, reduces uncertainty, and means you are less likely to be caught off guard when the admissions coordinator starts asking detailed questions.
Initial phone call and brief screening
The first call to a program is typically a brief conversation: what substance, how long, what kind of coverage you have. The admissions coordinator uses this to determine whether the program is a likely fit and what the next step looks like. This call is usually 15 to 30 minutes. You are not committing to anything at this stage.
Insurance verification
If TRICARE is your insurance, the admissions team will contact TRICARE to verify your benefits and determine what is covered for the level of care you need. This step is done by the admissions team, not by you. It typically takes 24 to 48 hours. The result tells you and the program what your out-of-pocket cost will be before any commitment is made.
Prior authorization (for residential and detox)
TRICARE requires prior authorization before you can be admitted to medical detox or residential treatment. The treatment center’s clinical staff submit documentation to TRICARE supporting the need for the level of care. Authorization typically takes one to three business days. The program will not admit you without it for levels that require it. Do not plan an admission date until authorization is confirmed.
Scheduling your admission date
Once insurance is verified and authorization is in place, you and the admissions coordinator schedule the date and time you will arrive. Most facilities can confirm an admission date within a few days of completing authorization. Some programs have waiting lists, particularly for residential beds. If there is a wait, ask to be placed on the list immediately so the clock starts running.
Pre-admission paperwork
Most facilities send consent forms, financial agreements, and HIPAA authorizations before your admission date. Complete these in advance if possible. Having them done means less time on paperwork when you arrive and more time with clinical staff. Ask the admissions coordinator what to bring with you on the day.
What to bring on admission day
Facilities provide packing lists when you confirm your admission date. In general, bring the following:
- A valid government-issued photo ID (military ID, driver’s license, or passport)
- Your TRICARE insurance card
- A written list of all current medications with dosages and prescribing provider’s name
- Enough comfortable clothing for the length of your expected stay
- Personal hygiene items that comply with the facility’s allowed list (some restrict aerosols or items with alcohol in ingredients)
- Prescription eyeglasses, hearing aids, or other medically necessary items
Leave valuables at home: expensive jewelry, large amounts of cash, and laptops are typically not permitted or secure in residential settings. Ask the facility in advance about their phone policy. Some programs restrict access during the first phase of treatment.
Do not bring loose prescription medications in unlabeled containers. Bring a clearly written list with medication name, dosage, and frequency. The facility’s medical staff will take it from there. Some programs require you to surrender all medications at intake so they can be dispensed by nursing staff.
What happens on admission day
Admission day can feel long. Most programs set aside two to four hours for the intake process. Here is what that time typically covers.
Check-in and orientation
You arrive, present your ID, and meet the admissions staff. You receive a brief orientation: a tour of the facility, an introduction to the rules and daily schedule, and information about confidentiality. If there is any remaining paperwork, you complete it now.
Medical intake assessment
A nurse or physician conducts a medical history review and physical examination. They ask about your current use, how long you have been using, any past withdrawal experiences, and your current medications and health conditions. Vital signs are taken. This information guides decisions about whether medical monitoring or detox medications are needed and at what level.
Psychiatric and behavioral health assessment
A counselor or mental health clinician conducts a separate assessment covering mental health history, current symptoms, trauma history, and your goals for treatment. For veterans, this often includes questions about military service, combat exposure, and PTSD screening. This is where co-occurring conditions are identified so treatment can address them.
Substance use history
This is a detailed conversation with a clinician about the history of your use: what substances, how much, how often, for how long, previous treatment attempts. Be as honest as you can. The clinical team is not there to judge. They need accurate information to plan appropriate treatment. Minimizing your history can result in a care plan that does not match what you actually need.
Treatment planning and initial goals
Based on the assessments, the clinical team begins developing your individualized treatment plan. This is a working document, not a final one. It outlines the level of care, the focus areas for treatment, and initial goals. You participate in this process and can raise priorities. Most treatment plans are formally reviewed and updated every week.
Getting settled
You are shown to your room, introduced to the unit, and given a schedule. The first evening is usually lower-key: a group meeting, dinner, and time to settle in. The structured daily schedule typically begins the following morning.
The first 72 hours
The first three days in treatment are often the hardest. You are likely in some degree of physical withdrawal, you are in an unfamiliar environment, and the decision to be there may feel uncertain. This is normal.
If you are in medical detox, nursing staff monitor you around the clock during this period. Withdrawal symptoms are managed with medications. The focus is entirely on your physical stabilization, not on therapeutic work.
If you entered at a residential level without needing detox, the first 72 hours involve settling into the routine, completing any remaining assessment elements, and beginning to meet your primary counselor and the other people in your cohort. Formal group therapy usually begins within the first day or two.
It is common to feel like leaving during the first few days. Many people do. The clinical team expects this and is trained to help you navigate it. If you are struggling, tell a staff member rather than acting on the urge to leave. The impulse usually passes.
Confidentiality: what stays private
Treatment records for substance use disorder carry some of the strongest federal confidentiality protections in medicine. Under 42 CFR Part 2, a treatment provider cannot confirm or deny that you are a patient, or share any information about your treatment, without your written consent, except in narrow emergency circumstances.
HIPAA also applies. The combination means your treatment is private by default. Your employer, your commanding officer, your family, and your insurance company cannot be told you are in treatment without your authorization. The only exceptions involve immediate risk to life.
If you want family members or your chain of command to be informed of anything, you sign a specific release of information form that you can revoke at any time.
If you are active-duty and self-referring to treatment, federal confidentiality law still applies. However, military-specific rules around fitness for duty and leave may create some practical considerations around informing your command. Read the full guide on self-referral versus command notification before admission if this is a concern.
