If you’ve heard someone say they got 5150’d, you’re probably wondering what that actually means and whether it’s something to be alarmed about.
The short answer: 5150 is the section of California’s Welfare and Institutions Code that allows someone to be held involuntarily for up to 72 hours for a psychiatric evaluation, because they appear to be a danger to themselves, a danger to others, or unable to care for their own basic needs due to a mental health crisis.
It’s not an arrest, and it’s not a diagnosis. It’s a temporary safety measure.
This guide walks through who can place a hold, what actually happens during those 72 hours, what rights the person retains, and what tends to happen next, the kind of practical detail that’s easy to miss when you’re searching for answers in a stressful moment.
What 5150 Actually Stands For
5150 isn’t slang or a nickname, it’s a literal section number. Section 5150 of California’s Welfare and Institutions Code, part of the Lanterman-Petris-Short (LPS) Act, <cite index=2-1>allows a person with a mental health challenge to be involuntarily detained for a 72-hour psychiatric hospitalization</cite>. The number has drifted into everyday slang (thanks in part to the Van Halen song of the same name) as shorthand for someone acting erratically, but the legal meaning is much narrower and more specific than the pop-culture use.
The law only applies in California. <cite index=1-1>Other states have similar emergency psychiatric detention laws, but they use different statutes, procedures, and terminology</cite>, so 5150 as a term doesn’t carry over legally outside California, even though the underlying concept a short emergency hold for evaluation exists almost everywhere in some form.
What Has to Be True for Someone to Be Placed on a 5150 Hold
A hold isn’t triggered by someone simply being upset, anxious, or behaving unusually. There are three specific legal thresholds, and at least one has to be met:
- Danger to self this is <cite index=4-1>typically interpreted as expressing suicidal ideation along with a plan</cite>, or having just attempted suicide.
- Danger to others meaning the person has communicated a specific threat and appears to have both the intent and a plan to act on it.
- Gravely disabled the person is unable to provide for their own basic needs, like food, clothing, or shelter, because of a mental health disorder.
Importantly, the person placing the hold has to have probable cause based on their own observation or reliable information not just a hunch or a report from someone who’s frustrated or scared without more concrete evidence.
What Is 5150d?
5150d is an informal way of saying that someone was placed under a 5150 psychiatric hold in California. The term comes from California Welfare and Institutions Code Section 5150. It generally refers to a situation where a person is believed to have a mental health crisis and may be a danger to themselves, a danger to others, or unable to care for themselves because of a mental health condition. The “d” simply turns 5150 into a verb-like slang expression.
Example 1: “He was 5150d after a serious mental health crisis.”
Example 2: “The family said she was 5150d and taken for an evaluation.”
5150d Someone
5150d someone is slang for having someone placed on a 5150 psychiatric hold in California. It does not mean that a person was simply arrested. A 5150 hold is related to an emergency mental health evaluation. The phrase is often used casually online, but the real process has specific legal requirements. Depending on the situation, a qualified professional or authorized person may request the hold when the legal criteria appear to be met. Because the term can sound harsh, it is best used carefully when discussing someone’s mental health situation.
Example 1: “They called for help because they were worried he might hurt himself and he was 5150d.”
Example 2: “She said her brother was 5150d during a severe crisis.”
51150 Meaning
51150 is usually a mistyped or rearranged version of 5150. In slang and online searches, people sometimes enter the numbers incorrectly because 5150 is the much more recognized term. The actual 5150 reference is associated with California law and emergency psychiatric evaluation. If you saw “51150” in a text, comment, or social media post, the writer may have intended to say 5150 rather than referring to a separate common slang term. Context matters, especially because numbers can have different meanings in different communities.
Example 1: “He wrote ‘51150’ but probably meant ‘5150.’”
Example 2: “What does 51150 mean here? It may simply be a typo for 5150.”
5150 Meaning
5150 commonly refers to a California law that allows certain people to be taken into custody for up to 72 hours for an emergency psychiatric evaluation when specific legal criteria are met. The term comes from California Welfare and Institutions Code Section 5150. In everyday speech, people may use “5150” as slang for someone experiencing a serious mental health crisis or being placed on such a hold. It is important to remember that 5150 is not simply another word for being mentally ill; the legal standard is more specific.
Example 1: “The doctor said he needed a 5150 evaluation.”
Example 2: “She used the word 5150 when describing the emergency mental health situation.”
51 50
51 50 is another way people may write 5150, especially in texts, searches, or social media. The numbers are often separated to make the phrase easier to read or to avoid automatic filters. Most commonly, 51 50 refers to the same California psychiatric-hold term as 5150. However, the meaning can change based on context, since separated numbers may also be used as a username, code, or reference unrelated to mental health. When the surrounding conversation mentions hospitals, crisis care, or psychiatric evaluation, 51 50 most likely means 5150.
Example 1: “They said he was on a 51 50 hold.”
Example 2: “I keep seeing ‘51 50’ online. Is it another way to write 5150?”
5150 Someone Meaning
5150 someone means, in informal language, to have someone placed under a 5150 psychiatric hold for an emergency mental health evaluation. The phrase is based on California law and is often heard in American slang. It should not be understood as meaning that someone can simply choose to “5150” another person whenever they want. Legal criteria must apply, and authorized professionals or officials are involved in the process. Online, people sometimes use the expression loosely to describe someone acting in an extremely unstable or unusual way.
Example 1: “The family called emergency services because they feared he might hurt himself and he was later 5150d.”
Example 2: “You should not use ‘5150 someone’ as a joke about ordinary strange behavior.”
5150 Meaning Chicago
5150 meaning Chicago usually points people to the general slang meaning of 5150, but the term itself comes from California law, not Chicago law. In everyday Chicago or broader U.S. slang, someone may still use “5150” to describe a person experiencing a serious mental health crisis or behaving in an extremely unstable way. However, using the term in Chicago does not automatically mean that California’s legal 5150 procedure applies. The exact legal process depends on the state and local laws involved.
Example 1: “Someone in Chicago might say ‘5150’ as slang even though the term originated in California.”
Example 2: “A Chicago conversation about 5150 may refer to a mental health crisis rather than a California legal hold.”
What Is 5051 Mean
5051 does not have the same widely recognized meaning as 5150. If you found “5051” while searching for information about 5150, it may simply be a typo, number reversal, or mistaken version of the term. The meaning can also depend on where you saw it, such as a text message, username, code, or social media post. It is therefore safer not to assume that 5051 means a psychiatric hold. If the surrounding text mentions mental health or emergency evaluation, the writer may have intended 5150.
Example 1: “I searched 5051 meaning, but the conversation actually seemed to be about 5150.”
Example 2: “She typed 5051 when she probably meant 5150.”
51 50 Meaning Urban Dictionary
On Urban Dictionary, “51 50” may appear as a slang-style spelling of 5150, with users connecting it to the idea of someone being mentally unstable or placed under a psychiatric hold. User-generated dictionary entries can explain how people use slang, but they are not legal definitions and may contain exaggerated, offensive, or inaccurate descriptions. The formal meaning of 5150 comes from California law, while slang versions such as “51 50” can be much broader. Always consider the context before deciding what someone means by the phrase.
Example 1: “He called his friend ‘51 50’ as slang for acting extremely unstable.”
Example 2: “The Urban Dictionary entry may explain the slang, but it does not replace the legal meaning of 5150.”
Who Can Actually Initiate a Hold
Not just anyone can place someone on a 5150. It’s limited to specific designated people: <cite index=5-1>licensed mental health professionals such as psychiatrists, psychologists, and clinical social workers, along with peace officers like police officers</cite>. A family member, friend, or even a general physician typically can’t place the hold directly; they’d need to contact law enforcement, a mobile crisis team, or a psychiatric emergency service and explain what they’re observing.
What Happens During the 72 Hours
The moment someone is placed on a hold, they’re taken to a hospital or facility that’s specifically <cite index=1-1>designated to accept 5150 admissions</cite> not every hospital can hold someone under this code. From there, the process generally looks like this:
- Medical screening. Staff check for injuries, intoxication, or other physical issues that could be causing or worsening the psychiatric symptoms, since a medical problem can sometimes look like a mental health crisis.
- Psychiatric evaluation. A clinician assesses the person’s mental state, history, and current risk level to figure out whether the criteria for the hold are still being met.
- Ongoing monitoring and treatment. <cite index=9-1>A treatment team typically including a psychiatrist, nurses, and social workers oversees care throughout the hold</cite>, which may include medication, stabilization, and safety planning.
- Discharge planning. Staff work out what happens after the hold ends, whether that’s release, a referral to outpatient care, or a recommendation for further inpatient treatment.
72 hours is a maximum, not a guarantee. <cite index=3-1>If the person no longer meets the criteria, they can be released earlier</cite> sometimes within a matter of hours. On the other end, if the crisis hasn’t been resolved, a longer hold can be requested (more on that below).
What Rights the Person Still Has
Being on a 5150 hold restricts someone’s freedom to leave, but it doesn’t strip away their other legal rights. People held under this code generally retain the right to:
- Receive humane care and be treated with dignity
- Refuse certain treatments in specific circumstances (with some exceptions, like emergency medication to prevent immediate harm)
- Contact an attorney and request a certification review hearing to challenge the hold
- Have visitors and make phone calls, within the facility’s reasonable rules
- Receive information about their diagnosis and treatment plan in a way they can understand
Facilities are required to explain these rights to the person, usually shortly after intake.
What Happens After the 72 Hours
There are generally three outcomes once the hold period ends:
Release. If the evaluating team determines the person is no longer a danger to themselves or others and isn’t gravely disabled, they’re free to go, sometimes with a referral for outpatient follow-up.
Voluntary continued treatment. Some people choose to stay longer on a voluntary basis if they and their care team agree that continued treatment would help.
A 5250 hold. If the crisis hasn’t resolved and the person still meets the legal criteria, <cite index=6-1>a 5250 hold can extend involuntary treatment for up to an additional 14 days</cite>. This isn’t automatic; it typically requires a certification review process, and the person has the right to challenge it.
5150 vs. Other California Mental Health Hold Codes
Because these numbers get used interchangeably in conversation, it helps to see them side by side.
| Code | Common Name | Duration | Who It’s For |
| 5150 | Emergency hold | Up to 72 hours | Adults in acute crisis: danger to self, danger to others, or gravely disabled |
| 5250 | Certification hold | Up to 14 days | Adults who still meet criteria after the initial 72-hour hold |
| 5270 | Extended treatment | Up to 30 days | Cases requiring further stabilization after a 5250 hold |
| 5585 | Juvenile hold | Up to 72 hours | Minors under 18 who meet the same danger/gravely disabled criteria |
Each step up requires its own separate evaluation and legal justification. A facility can’t simply extend a hold because it’s convenient or because staff feel more time would help in general.
A Few Practical Realities Worth Knowing
A 5150 is not a criminal record. It doesn’t show up on a background check the way an arrest would, and it’s not, by itself, evidence of a permanent condition or an ongoing danger.
That said, it does carry one specific real-world consequence: <cite index=8-1>someone who has undergone a 5150 hold is prohibited from purchasing or possessing firearms for a five-year period</cite> under California law. This applies regardless of how the hold is resolved or whether charges were ever involved, since the hold itself is the triggering event.
It’s also worth knowing that a hold can feel frightening or humiliating to the person going through it, even when it’s genuinely meant to keep them safe. If you’re supporting someone who’s been through this, patience and a calm, non-judgmental tone in the days after usually matter more than trying to explain the legal process to them right away.

Conclusion
A 5150 hold is a short, legally defined emergency intervention not a diagnosis, not a punishment, and not permanent. It exists to give someone in crisis a safe 72-hour window for evaluation and stabilization, with real legal rights protecting them the entire time. If you’re trying to understand this because you or someone you know may be facing one, it can help to talk directly with the facility’s social worker or a local NAMI chapter, since they can walk through what to expect in your specific situation.
