A plain-language decision guide to 988, STAR, the Colfax Crisis Stabilization Unit, and what comes after — written for the person making the call, not the person writing policy
This is not a phone-number list. Denver already has those, and they don’t answer the questions that actually come up at 10 p.m. on a Tuesday when someone you care about is in crisis: Who shows up if I call this number? How long will we wait? What will happen to them inside that building? What does it cost if they’re uninsured? Can I take time off work to deal with this?
October is a reasonable time to have this conversation — not because crisis doesn’t happen in July, but because the stretch from Halloween through February is when Denver’s behavioral health infrastructure faces its heaviest demand. Isolation, financial pressure, shorter days, and disrupted routines compound. Acute psychiatric emergencies rise. The 988 Suicide and Crisis Lifeline has been live for two years and is still widely misunderstood. STAR is three years old and most Denver residents have never heard of it. The Crisis Stabilization Unit at 4353 E. Colfax has been open as a walk-in alternative to the ER for years, and most families find out about it only after an ER visit that didn’t go the way they hoped. That last part is a problem this guide is trying to fix.
This covers the acute end of the behavioral health spectrum — what to do when weekly therapy isn’t the question and the situation is happening now. It’s written for the person making the call. Usually a family member or friend. Usually stressed. Usually working with incomplete information.
The Four Pathways Denver Residents Actually Have
In Denver, a behavioral health crisis has four meaningfully different response options. They produce different outcomes depending on who shows up, how fast, with what clinical capacity, and what happens to the person afterward.
Call 911 — Default dispatch is police. But Denver’s 911 system has a triage layer that can route appropriate calls to STAR (a paramedic-and-clinician team) instead. The caller has real influence over which response gets sent.
Call 988 — Calls from Denver route to Rocky Mountain Crisis Partners, Colorado’s designated 988 crisis center. This is not a national call bank. It’s a Colorado-specific operation with mobile response capacity — a 988 call can result in clinicians arriving on scene, not just a phone conversation.
Go to the Crisis Stabilization Unit at 4353 E. Colfax — Walk-in intake, no appointment, no waiting in a general-population ER. The CSU is the city’s primary purpose-built crisis facility. It operates differently from a hospital, bills differently, and exists for exactly this level of care.
Go to an emergency room — Appropriate in specific circumstances, but often not the fastest or most clinically appropriate first stop for a psychiatric emergency that isn’t simultaneously a medical one.
STAR: What It Is, How to Get It, and What It Can’t Do
STAR (Support Team Assisted Response) pairs a mental health clinician with a paramedic and sends them, without police, to 911 calls triaged as appropriate for a non-law-enforcement response. Denver launched it in 2020. The city’s own program evaluations consistently show STAR responses result in very low rates of arrest or criminal justice involvement. That’s the point — and by the numbers, it largely works.
Here’s what most people don’t know: there is no separate STAR number. You call 911. The triage happens inside the dispatch system. A dispatcher evaluates whether the call fits STAR criteria and routes accordingly. The criteria matter: STAR responds when there’s no confirmed weapon and no confirmed violence. If a weapon is present or a crime is in progress, police go first. STAR handles the large category of mental health calls where danger isn’t the central issue.
When you call 911, be specific. Tell the dispatcher: “I’m calling about a mental health situation. The person is not violent and does not have a weapon. I don’t think police are needed — this is a psychiatric emergency.” Then describe what you’re actually seeing. Suicidal statements. Disorientation. A panic episode. Erratic behavior with no threat to anyone. The clearer you establish that this is behavioral health with no safety component, the better your chances of a STAR-appropriate dispatch.
After STAR arrives, the clinician assesses the person, provides immediate stabilization, and can connect them to follow-up services. Importantly, STAR teams can transport directly to the Crisis Stabilization Unit on Colfax. They don’t hand you a pamphlet and leave.
Now the honest part, and it matters: STAR doesn’t run around the clock. Coverage is concentrated in daytime and early evening hours, with reduced or no staffing overnight and on some weekend shifts. Team count also isn’t uniform across the city. If you call 911 at 2 a.m. for a mental health situation with no danger, you may get a police unit anyway. This isn’t a footnote — it’s a real structural gap, and residents in the far northeast and southwest of the city feel it most. Current confirmed operating hours are available through the Denver Department of Public Health and Environment. Check before you assume STAR will be an option.
988 in Denver: What Actually Happens When You Call
The dominant misperception about 988 is that it’s a phone bank — someone talks you through the moment, and that’s it. In Colorado, that’s not the full picture. Denver-area calls route to Rocky Mountain Crisis Partners, which has mobile response dispatch built into its 988 network. A 988 call can get clinicians dispatched to your location. Not as an escalation you have to argue for. As a built-in option the counselor can offer based on what’s available in your area at that hour.
The comparison to 911 is worth making directly: calling 911 routes by default to police, with STAR possible under certain conditions. Calling 988 routes by default to a mental health clinician, with mobile response possible. That default clinical orientation is 988’s structural advantage over 911 for most behavioral health situations — and most people don’t register it until they’re already deciding which number to dial.
If speaking aloud isn’t safe — the person in crisis is in the next room, or talking would escalate things — you can text 988 or use chat at 988lifeline.org. Both channels are handled by Colorado’s 988 system.
When you call, ask the counselor directly: “What mobile response options do you have in my area right now?” Don’t assume it’s available or that it isn’t. Response capacity varies by location and time of day, and the fastest way to find out what’s possible is to ask the person on the line. If mobile response isn’t available at that hour, the counselor can still help you figure out what is — including whether transport to the CSU makes sense.
The Crisis Stabilization Unit on Colfax: What Happens Inside
The CSU at 4353 E. Colfax Ave. is Denver’s primary walk-in psychiatric crisis facility. Before you decide whether to bring someone there, you need to understand what it is and what it isn’t.
No appointment. No referral. You can walk in, or arrive by EMS drop-off. Staff conduct an assessment on arrival. The intake process is oriented toward stabilization, not paperwork.
Stays typically run up to five to seven days, with the goal of stabilizing the person and connecting them to a lower level of care — intensive outpatient programming, community-based support, a treatment provider. If someone needs more than the CSU can provide, clinical staff can facilitate that transfer.
Most CSU admissions are voluntary. Colorado law allows a 72-hour involuntary psychiatric hold — an M-1 hold — when a person is determined to be an imminent danger to themselves or others. An M-1 hold can be initiated by a licensed mental health professional, a peace officer, or a physician. If you bring someone in voluntarily, the goal is to keep the process collaborative. But if the clinical assessment determines involuntary hold criteria are met, that can change. Knowing this before you walk through the door matters — both for the person in crisis and for the family member sitting with them.
The question families ask most, and that most guides dodge: what does it cost? The CSU doesn’t charge an ER facility fee. Medicaid is accepted. Private insurance is accepted. Uninsured patients are served on a sliding-scale model based on income. The specific current self-pay rates require direct verification with the facility — billing policies change and we won’t publish figures that may be stale. What we can say: the CSU is designed specifically to be accessible outside the hospital billing structure, including for people without insurance. If cost is a concern and you have time to make one call before arriving, call the facility.
Current operating hours, licensed bed count, and precise uninsured cost policy should be confirmed directly with the CSU before your visit. The facility has operated continuously, but operational details shift.
The ER: When It’s Right and What to Expect
There are situations where the emergency room is where you go. When someone is in immediate physical danger. When there’s a co-occurring medical emergency. When the severity of the situation is beyond what a community crisis facility can safely manage. But arriving at a general ER with a psychiatric emergency typically means: a general-population waiting room, sometimes for hours, before psychiatric consultation reaches you. The environment isn’t built for this. The cost — including ER facility fees — is substantially higher than a crisis stabilization unit.
Denver Health operates a dedicated psychiatric emergency room, separate from general ER triage. It works differently: faster access to psychiatric consultation, different intake process. Denver Health carries a safety-net role for uninsured and Medicaid patients. Confirm current hours and capacity directly with Denver Health before relying on them.
UCHealth Anschutz is the metro area’s primary academic medical center for high-acuity psychiatric care. It’s in Aurora — not Denver city limits. That’s a real logistical consideration that families don’t always register until they’re already driving. St. Joseph Hospital in Uptown has psychiatric services within a general hospital. For current psychiatric capacity at any of these facilities, call before you go.
For a psychiatric emergency without a simultaneous medical component, the CSU on Colfax is almost always a faster, more appropriate, and less expensive first stop than a general ER. The ER becomes the right call when the physical danger is real and immediate, or when the CSU has assessed the situation and determined someone needs a higher level of care.
What to Say When You Call
These aren’t scripts. They’re the specific pieces of information that help dispatchers and clinicians route the right response. Having thought about this in advance is worth something.
Calling 911: “I’m calling about a mental health emergency. The person is not violent and does not have a weapon. I don’t think police are needed — this is a psychiatric situation.” Then describe specifically what you’re seeing. She’s been expressing suicidal thoughts and hasn’t responded to conversation in the past hour. He’s disoriented and I can’t reach him. Specific descriptions help the triage process work.
Calling 988: Tell the counselor what’s happening, give your location, and ask: “What mobile response options do you have available in my area right now?” If mobile response isn’t on the table at that hour, the counselor can still walk you through next steps.
Going to the CSU: If you have time, bring the insurance card, a list of current medications with dosages, and the name and number of any existing treatment provider. None of this is required — the CSU will conduct intake regardless. But it speeds up the clinical picture and improves the quality of the assessment. If you have none of it, go anyway. Don’t let the absence of a medication list keep you in the driveway.
After the Crisis: Intensive Outpatient Programs in Denver
Once someone has stabilized — left the CSU, completed a short inpatient stay, moved through the acute phase — the question is what comes next. Weekly therapy is often not enough for someone who has just come through a psychiatric crisis.
The clinical step between inpatient care and weekly outpatient therapy is an Intensive Outpatient Program: typically three hours per day, three to five days per week, for six to eight weeks. Structured group and individual therapy, usually with a specific focus — depression and anxiety, trauma, substance use and co-occurring disorders. The person goes home each day. Partial Hospitalization Programs (PHPs) are more intensive, typically five to six hours daily, and sit between inpatient and IOP. For broader context on how Denver’s behavioral health and primary care options interact, our health and wellness coverage addresses the city’s provider landscape in more depth.
Mental Health Center of Denver (MHCD) is the largest community mental health center in the city and the primary IOP and PHP provider for Medicaid-enrolled and low-income residents. Multiple sites, sliding-scale fees. It’s often the most accessible option for uninsured or underinsured Denver residents — but the wait is real. Many MHCD program waits run two to six weeks, sometimes longer for specific tracks. That’s a serious problem, and I’ll get to it directly in the next section.
Colorado Recovery, at 3180 E. Magnolia St., focuses on serious mental illness — psychotic disorders, bipolar disorder, long-term psychiatric conditions. More specialized than a general IOP; different population. UCHealth Behavioral Health runs outpatient and intensive outpatient services tied to the Anschutz system, with some Denver-accessible locations. Private insurance is the primary access route; verify Medicaid acceptance directly.
Medicaid covers IOP when medically necessary, and post-crisis care frequently meets that threshold. Private insurance is required under Colorado’s mental health parity law to cover IOP at the same level as comparable medical treatment — your insurer cannot apply stricter standards to psychiatric IOP than to physical rehabilitation. Self-pay rates vary significantly by provider.
Most IOP infrastructure in Denver is clustered in central Denver and the central-east corridor. Residents in Montbello, Westwood, Barnum, and southwest Denver face genuine access barriers — fewer options, longer distances, and in some cases real language access problems. This is a structural equity failure in how Denver’s behavioral health system was built. It doesn’t get talked about enough.
Colorado FAMLI: The Leave Benefit That Covers This Situation
Most guides on this topic stop at clinical resources and say nothing about what happens to your job when a family member is in crisis. That’s a real omission. Whether you can afford to take time off often determines whether a family can actually engage with treatment at all.
Colorado’s FAMLI program (Family and Medical Leave Insurance) began paying benefits in January 2024. It’s a state-run paid leave insurance program funded by payroll contributions. It covers serious health conditions — including mental health conditions — and it covers leave to care for a qualifying family member, not just your own condition. A parent, partner, or sibling managing a family member’s acute psychiatric episode, accompanying them through CSU intake, or arranging an inpatient placement may have a legal right to paid FAMLI leave. The program’s definition of qualifying family members is broad; confirm the current list with the FAMLI Division directly.
Whether attending IOP yourself — as opposed to caring for someone else in inpatient care — qualifies under FAMLI’s “continuing treatment” framework requires direct verification. A strong argument exists that it does, since the program covers your own serious health condition requiring ongoing treatment. But this is a policy interpretation that can shift, so don’t assume it either way. Denver employers navigating the cost side of this program are covered in how Denver small employers are managing Colorado FAMLI costs at the one-year mark.
For current eligibility and claims information, go to the Colorado FAMLI Division at cofamli.colorado.gov. The Division operates a direct line for employee questions. The program’s eligibility rules are more accessible than most state benefit programs, which is worth knowing.
Where Denver’s System Falls Short
I want to be direct here, because the gaps aren’t minor. They affect real people at the worst possible moments.
A non-police mental health response that doesn’t run around the clock is an infrastructure gap, not a program success. Late-night crises are common — anyone who has been through this knows they often happen at 2 a.m., not 2 p.m. — and they frequently default to police response regardless of whether that’s appropriate. STAR’s limited hours are a real problem for families dealing with this when the rest of the city is asleep.
One walk-in crisis facility for the entire city of Denver is not sufficient coverage. A resident in Montbello does not have the same access to the CSU as a resident in Capitol Hill — in distance, transit, and time. It’s genuinely unclear to me why this hasn’t moved faster, given how long it’s been a known gap.
Two-to-six-week waits for intensive outpatient care after an acute crisis represents a real failure in the step-down system. For many people, that window between discharge and IOP enrollment is exactly when things fall apart again. The system looks coherent on paper and breaks down in the gap between stabilization and follow-up. This is where I’d most like to see Denver push.
Language access is uneven across the system. Whether the CSU on Colfax has equivalent Spanish-language intake capacity requires direct verification with the facility — and it matters enormously for the Spanish-speaking families in Westwood, Barnum, and Sun Valley who are effectively navigating their own crisis infrastructure in a second language. That’s a specific, fixable problem. Denver’s behavioral health system needs to answer for it directly.
