Addiction treatment comes with its own language, and most families learn it the hard way — in the middle of a crisis, from someone who is talking fast. This page breaks down the terms you are most likely to encounter so you are not guessing at meaning while trying to make decisions for someone you love.
Levels of Care
Detox — Medical stabilization to safely manage withdrawal symptoms before treatment begins. Not technically a level of care on its own, but the first step for many people.
Residential Treatment (RTC) — 24-hour care in a structured facility where the patient lives on site full time.
Partial Hospitalization Program (PHP) — A high-intensity outpatient level of care, typically 5 to 6 hours a day, 5 days a week, without overnight stay at the facility.
Intensive Outpatient Program (IOP) — A step down from PHP, typically 3 hours a day, 3 to 5 days a week.
Outpatient (OP) — The lowest level of care, usually one to two sessions per week.
LOC (Level of Care) — Shorthand for the intensity of treatment being recommended or provided, such as residential, PHP, or IOP.
Step Down — Moving from a higher intensity level of care to a lower one as a patient progresses, such as residential to PHP to IOP.
Step Up — The reverse — moving to a higher level of care because a lower one is not providing enough support.
Insurance and Admissions
Medical Necessity — The clinical justification insurance companies require before authorizing a level of care. Based on documented severity, risk, and prior treatment history.
Utilization Review — The process by which an insurance company evaluates whether a requested level of care meets their medical necessity criteria, often repeated throughout a treatment stay to determine continued coverage.
Peer to Peer Review — A call between a facility's physician and an insurance company's reviewing physician to argue for continued authorization of a level of care, usually when a denial has occurred or is being considered.
Prior Authorization — Approval required from an insurance company before treatment begins, confirming they will cover the cost.
In Network vs. Out of Network — Whether a facility has a contracted rate with your insurance company. In network is typically lower cost. Out of network may still be covered partially depending on your plan.
Single Case Agreement — A negotiated arrangement where an out-of-network facility is treated as in network for a specific patient, sometimes used when no appropriate in-network option is available.
ASAM Criteria — A standardized set of guidelines published by the American Society of Addiction Medicine used by clinicians and insurance companies to determine appropriate level of care.
EOB (Explanation of Benefits) — A document your insurance company sends after a claim is processed, showing what was billed, what was covered, and what you owe.
Deductible — The amount you must pay out of pocket before your insurance begins covering costs.
Out of Pocket Maximum — The most you will have to pay in a given plan year before insurance covers 100 percent of costs.
COWS (Clinical Opiate Withdrawal Scale) — A clinical tool used to assess the severity of opioid withdrawal symptoms, often used to determine when medications like buprenorphine can be safely administered.
Clinical and Diagnostic Terms
SUD (Substance Use Disorder) — The clinical diagnostic term for what is commonly referred to as addiction.
AUD (Alcohol Use Disorder) — The clinical diagnostic term specifically for alcohol addiction.
OUD (Opioid Use Disorder) — The clinical diagnostic term specifically for opioid addiction.
Dx (Diagnosis) — Shorthand for a clinical diagnosis, often seen in intake paperwork.
Dual Diagnosis / Co-Occurring Disorder — When a person has both a substance use disorder and a mental health diagnosis — such as depression, anxiety, or PTSD — occurring at the same time.
BH (Behavioral Health) — A broad term covering both mental health and substance use treatment, often used in insurance and billing contexts.
Treatment and Recovery
MAT (Medication-Assisted Treatment) — The use of medications such as buprenorphine, methadone, or naltrexone alongside counseling to treat substance use disorders, most commonly associated with opioid addiction.
Precipitated Withdrawal — A sudden, severe withdrawal reaction caused by administering buprenorphine too early, before opioids have sufficiently cleared the system.
AMA (Against Medical Advice) — When a patient leaves a treatment facility before completing the recommended course of care, against the recommendation of the clinical team.
Relapse — A return to substance use after a period of abstinence. Often part of the recovery process rather than a sign of treatment failure, though it carries real risk and should be addressed seriously.
Sober Living — A structured, substance-free housing environment for people in recovery, typically used as a step between treatment and independent living.
Aftercare — The ongoing support and treatment plan following completion of a primary treatment program, which may include outpatient therapy, sober living, or support groups.
CRAFT (Community Reinforcement and Family Training) — An evidence-based approach that teaches families how to help motivate a resistant loved one toward treatment without confrontation.
Intervention — A planned conversation or meeting, sometimes professionally facilitated, intended to encourage someone to accept treatment for substance use.
Discharge Planning — The process of preparing a patient for what happens after they leave a facility, including aftercare, sober living, and continued treatment recommendations.
Continuum of Care — The full range of treatment levels a person may move through, from detox through aftercare, ideally as a connected and coordinated process.
Wraparound Services — Additional support services offered alongside primary treatment, such as case management, vocational support, or family therapy.
Operational Terms
DOA (Date of Admission) — The date a patient is admitted to a facility, used in scheduling and insurance documentation.
LOS (Length of Stay) — The total duration of a patient's treatment episode at a given level of care.
TX (Treatment) — Common shorthand used in clinical notes and admissions paperwork.
Census — The number of patients currently in a facility's program, sometimes referenced in the context of why a bed is or is not available.
Bed Availability — Whether a facility has an open spot for a new admission, which can change daily and affects how quickly someone can be admitted.
Patient Brokering and Industry Abuse
Patient Broker — A recruiter, sometimes called a body broker, who is paid a kickback to steer patients with good insurance toward specific treatment facilities, without regard for clinical fit or quality of care. Patient brokering is illegal in Florida and several other states.
Body Broker — Informal term for a patient broker. The name reflects the transactional nature of the arrangement: people in crisis are treated as billing units rather than patients.
Kickback — A payment made to a referral source in exchange for sending patients to a facility. In the treatment industry, kickbacks have taken the form of cash, gift cards, free travel, and other incentives. Paying or receiving kickbacks for patient referrals is a federal crime under the Anti-Kickback Statute.
Florida Shuffle — A pattern in which patients are cycled between treatment centers and sober living homes driven by insurance billing rather than clinical need, rather than genuine clinical progress. Originally concentrated in South Florida, the model has since spread to other states.
Liquid Gold — Industry slang for urine drug testing, which became one of the most aggressively overbilled services in the Florida Shuffle era. A single urinalysis panel that should cost a small amount was routinely billed to insurance companies for thousands of dollars.
