Who Can Be Told You’re in Rehab? 42 CFR Part 2

Substance use disorder treatment records in the United States are covered by a separate federal confidentiality rule from the rest of health care. That rule is 42 CFR Part 2, backed by the statute at 42 U.S.C. 290dd-2, and SAMHSA describes it as applying to any federally assisted program that provides SUD diagnosis, treatment, or referral for treatment. In practice it means a residential addiction treatment program in Los Angeles generally cannot tell a caller whether a named person is a patient there — not an employer, not a sibling — without that person’s written consent already on file.

That single fact surprises more families than anything else in the admissions conversation. People assume HIPAA is the whole story. For substance use treatment, it is not.

Why substance use records carry an extra layer of protection

Ordinary medical records are protected, but substance use records are protected further because the consequences of disclosure are different in kind. A leaked record can follow someone into a custody dispute, a professional licensing board review, an immigration file, or a performance review. Congress and federal regulators concluded decades ago that if people believed treatment records could travel, they would not walk through the door at all.

The scale of what is at stake is not small. SAMHSA’s 2025 National Survey on Drug Use and Health, released on 27 July 2026, was built on self-reported responses from more than 60,000 people aged 12 and older — a survey that only works because respondents trust that what they say about their own substance use stays where they put it. The same logic runs through Part 2.

Who Part 2 binds, and who it follows

Part 2 applies to the treatment program itself, but it does not stop at the program’s door. SAMHSA’s summary of the statutes and regulations governing substance use treatment notes that some Part 2 requirements also reach people and organisations that receive Part 2 records — other health care providers, qualified service organisations, HIPAA covered entities and their business associates, intermediaries, and investigative agencies. A record does not lose its protection simply because it has been handed onward.

This is why a residential program will often ask a referring therapist or a primary care physician to sign paperwork before a record moves, even when that clinician already knows everything in it.

The disclosures that do not require a signature

Consent is the default, not the only route. A short list of exceptions exists, and it is narrower than people expect.

Medical emergencies: information may be shared with medical personnel when there is an immediate threat to health and delay would be dangerous, which is what allows a program to hand a paramedic a medication list during a seizure.

Communication inside the program: staff within the same program who need the information to do their jobs may share it, so the nurse, the physician, and the primary therapist are not each working blind.

Qualified service organisations: contracted services such as a laboratory or billing company may receive what they need under a written agreement that binds them to the same rules.

A court order specific to Part 2: a judge may authorise disclosure after a particular procedure, and this is the point families most often get wrong — a subpoena on its own is not the same thing as a Part 2 court order, and a program that hands over records on a subpoena alone may be in the wrong.

Mandated reporting of suspected child abuse or neglect: state reporting duties still apply, though the protections around the treatment record itself remain in place.

How to read a consent form before you sign it

Here is something you can do at your next admissions call, before any money or any bed is discussed. Ask for a blank copy of the program’s consent-to-disclose form and read three things on it: who is named as the recipient, what categories of information are listed, and when the consent expires or what event ends it.

Then ask for the categories to be split. A consent can authorise a parent to be told that you arrived safely, that you are medically stable, and what your discharge date looks like, while withholding the content of your therapy sessions and your toxicology results. That division is permitted. If a program tells you it is all or nothing, that is that program’s internal policy, not a federal requirement, and it is a fair thing to push back on.

What this looks like inside a six-bed residence

Confidentiality in a small private home is a physical problem as much as a legal one, and it is worth being honest about the trade-offs. In a six-bed house, residents see each other at breakfast. No consent form covers what one resident observes about another, which is why house agreements about peer confidentiality are signed on day one and taken seriously.

The operational reality that surprises callers most: when an employer telephones and says they only want confirmation that someone is here, the program cannot answer either way. Saying no is a disclosure just as saying yes is, because a denial about one person and silence about another tells the caller everything. So the answer is always the same neutral script, regardless of who is or is not a resident.

One more thing that is inconvenient but true. Consent forms are usually signed on admission day, which is frequently the day someone is sickest and least able to weigh a decision carefully. A person in the first hours of alcohol or opioid withdrawal is not in a good position to decide who gets told what for the next six months. Revisiting those forms once withdrawal has settled — and being willing to narrow them — is a small practice that matters, and it is reasonable to ask a program whether it does this.

Detox is where confidentiality and safety meet

Withdrawal from alcohol and from benzodiazepines can involve seizures and, in the case of alcohol, delirium tremens, and both require medical supervision rather than a private attempt at home. Safe medical detox in Los Angeles depends on the clinical team sharing information freely among themselves, which Part 2 permits, while the perimeter around that information stays closed.

If someone is transferred to a hospital during detox, the medical emergency exception allows the treating clinicians to receive what they need. Confidentiality was never designed to make care less safe.

Co-occurring conditions live in the same protected record

Many people entering residential treatment for a substance use disorder are also carrying depression, anxiety, PTSD, insomnia, or chronic pain, and those conditions are addressed alongside the substance use rather than separately. When that care is delivered within a Part 2 program, the notes about a co-occurring condition sit inside the same protected record. Families exploring dual diagnosis treatment in Los Angeles should understand that the whole file travels under the same rule — and the same consent form governs it.

Questions worth asking before you admit

Ask who at the program is authorised to answer the phone about residents, and what they say. Ask whether consent forms are reviewed again after detox. Ask what the program does if it receives a subpoena. Ask how records are transmitted to an outside provider, and whether it is by fax, encrypted portal, or email. Ask what appears on an insurance explanation of benefits that goes to a policyholder who is not the patient, because that document is a common and overlooked route of disclosure within families.

Getting help

If you or someone in your family is weighing residential treatment, you can reach us at (855) 778-8668. SAMHSA also operates a free, confidential National Helpline at 1-800-662-HELP (4357), available around the clock in English and Spanish. If someone is in immediate crisis, call or text 988 to reach the Suicide & Crisis Lifeline, and call 911 for a medical emergency such as a suspected overdose or a withdrawal seizure.

Confidentiality rules are applied to specific facts, and questions about your own situation should be directed to a qualified clinician or attorney. Do not stop or reduce alcohol, benzodiazepine, or opioid use without medical guidance, as withdrawal from some substances carries serious risk.
