Colorado Behavioral Health Credentialing and Medicaid Enrollment

In Colorado the behavioral health money doesn’t sit with the state. It sits with four Regional Accountable Entities, and if you aren’t contracted with your patient’s RAE you can’t bill the RAE, and under C.R.S. 25.5-4-301 you can’t bill the patient either. Enrolling with Health First Colorado is the first half of the job. The RAE contract is the half that decides who you’re allowed to see.

Colorado payers and timelines

Where the delays actually happen

Getting on a panel isn’t the same as getting paid.

Colorado’s state enrollment is rarely the thing holding you up. HCPF’s fiscal agent reports averaging about eight business days on new applications. What holds you up is the second decision, made by somebody else: a RAE deciding whether it wants your contract, and a commercial carrier deciding whether it needs you. Colorado is not an any-willing-provider state, so both of those are real decisions and not formalities.

Credentialed›contracted›loaded›connected›payable

Two tracks

One enrollment, then four possible contracts. Then the commercial side.

Health First Colorado got structurally simpler on July 1, 2025 when the RAE map went from seven regions to four. The commercial side is the harder half, and it carries two Colorado traps that cost people weeks.

Health First Colorado

Enroll with the state. Contract with the RAE. Both, in that order.

HCPF pays each Regional Accountable Entity a capitated behavioral health benefit. The RAE is the behavioral health payer. Since ACC Phase III launched on July 1, 2025 there are four of them, running through June 30, 2032.

How you enrollThrough the Colorado interChange Provider Enrollment Portal. The first real decision is the enrollment type, because it decides who can bill. Group is the billing entity for a practice. Individual Within a Group is a clinician who renders but doesn’t bill the state directly. Billing Individual is a clinician paid under their own Social Security number. OPR is for someone who only orders, prescribes or refers and never files a claim. The common solo pattern is two applications, not one: enroll the business as a Group under Provider Type 16, Clinic Practitioner Group, then file as an Individual Within a Group affiliated to it. Colorado allows only one application per Social Security number across the individual types, and a duplicate can be denied outright.

The four RAEs, by regionRocky Mountain Health Plans holds Region 1, 34 counties across the Western Slope, mountains, San Luis Valley and Pueblo. Northeast Health Partners holds Region 2, 18 counties on the northern Front Range and Eastern Plains, and Larimer and Elbert moved into it at the Phase III transition, so older directories put them somewhere else. Colorado Community Health Alliance holds Region 3, including Boulder, Jefferson and El Paso. Colorado Access holds Region 4: Adams, Arapahoe, Denver and Douglas.

A panel that looks like enrollment and isn’tThe Network Participation panel in the portal lets you list managed care networks you take part in. HCPF says plainly that adding a network there does not create an enrollment in that network. The RAE contract is still a separate process with a separate party, and people lose months believing they already did it.

Two managed care wrinklesMembers in Rocky Mountain Health Plans PRIME get both physical and behavioral health through RMHP, so where you would otherwise bill HCPF fee-for-service you bill the plan instead. And behavioral health for Elevate (Denver Health) Medicaid Choice members is managed by Colorado Access, not by Denver Health. A member can show two active managed care enrollments at once.

Commercial

Colorado retired its own credentialing form, and payers still ask for it.

Anthem holds both the Blue Cross and the Blue Shield license here, so Colorado is a single-Blue state. A typical opening set is Anthem, UnitedHealthcare through Optum, then Aetna, then Select Health or Kaiser through Carelon depending on where you practice.

The retired formThe Colorado Health Care Professional Credentials Application at 6 CCR 1014-4 was repealed effective March 17, 2023, along with the rule that made it mandatory. Payer documents still name it. When one does, it means a complete, attested CAQH profile with that payer authorized. Optum states outright that CAQH participation is required for credentialing in Colorado.

Your CAQH stays yoursYou complete and attest your own profile. We’re added as an authorized practice manager, so we keep the practice data current and get each payer authorized. Anthem publishes an unusually specific definition of a complete application: license and DEA or controlled-substance certificate in every state where you practice, education supporting each requested specialty, hospital privileges, five years of work history in month and year format, and current liability coverage. Miss one and the file gets returned rather than worked.

Behavioral health has its own doorUnitedHealthcare’s is Optum, through Provider Express. Cigna’s is Evernorth. Aetna handles behavioral health itself but on a separate Behavioral Health request for participation, including when you’re joining a medical group. Kaiser Permanente Colorado publishes Carelon Behavioral Health as the route for community behavioral health providers in Colorado Springs, Pueblo, Cañon City and Northern Colorado. Anthem routes behavioral health through the same entry point as medical while Carelon is its behavioral affiliate and Colorado provider-relations contact, so that one we verify at filing rather than assume.

Seeing patients in other statesOne Anthem Colorado contract reaches Blue members in other states through BlueCard. Aetna, Cigna and UnitedHealthcare are national, so one contract covers every state you’re licensed in. The gate to an out-of-state patient is a license where the patient is, not another contract. Joining a different state’s network is a separate question and some states ask about physical presence. Medicaid is the real exception: Health First Colorado enrollment and RAE contracts are Colorado-only and don’t travel.

Colorado commercial payers

Who you’ll apply to, and how long it usually takes.

These are typical ranges from a complete application, drawn from what each carrier publishes. Two Colorado panels are effectively unavailable right now and we say which. We track these timelines rather than promise them.

Anthem Blue Cross and Blue Shield of Colorado

The single in-state Blue. Both licenses sit here.

Credentialing: Anthem says about 45 days from the point its credentialing department receives your completed CAQH application. That’s the credentialing half only. Contracting is separate and has its own clock
Recredentialing: every three years, and Anthem warns that failing to keep CAQH updated at recredentialing results in administrative termination from the network
Behavioral health door: Anthem’s own application flow puts behavioral health, primary care and specialty through the same entry point, while Carelon is Elevance’s behavioral affiliate and the published Colorado contact for behavioral health credentialing questions. We confirm the current route before filing instead of assuming either way
Why it matters here: Anthem is one of six carriers in Colorado’s 2026 individual market and also sits inside the Colorado Community Health Alliance RAE on the Medicaid side. Those are separate contracts

Optum Behavioral Health (UnitedHealthcare)

Initiated on Provider Express

Usually: about 60 to 120 days from a complete application
Published green light: Optum’s Colorado page lists MDs, DOs, PAs and RNs with prescriptive authority as actively sought in all counties, and separately names telemental health, medication-assisted treatment prescribers, Express Access providers who can see a member within five business days, and EAP
CAQH: required before you can start the Colorado application. No CAQH ID means registering first
Read the fine print: Optum is equally direct that it accepts applications based on network need and that a request is not a promise of a recruitment offer

Separate door: Optum Behavioral Health

Aetna

Contracts first, credentials second

Usually: about 60 to 120 days from a complete file, with an eligibility answer on network need inside 45 days
Sequence: request for participation, network-need evaluation, contracting, then credentialing pulled from CAQH, then contract finalization. That order is backwards from most carriers and it changes what we chase first
Watch: behavioral health professionals use Aetna’s separate Behavioral Health request for participation, including when joining a medical group. Starting on the medical form costs weeks

Separate form: Aetna Behavioral Health

Cigna Healthcare

Behavioral health goes through Evernorth

Right now: Evernorth paused new individual and clinic behavioral health applications on June 1, 2026 and points applicants at a provider interest form or a return visit after September 1, 2026. The pause is national, not a Colorado decision. Facilities can still apply, and anything started before June 1 keeps processing
Once reopened: Evernorth has said the full process can run up to about 90 days
Liability minimums to know: $1 million per occurrence and $3 million aggregate for physicians and psychiatric nurses with prescriptive authority. Evernorth also requires participation at all your service locations rather than at selected tax IDs
Our read: don’t build a Colorado opening panel around Cigna today, even though Cigna is one of the six carriers in the 2026 individual market. Optum is the usual substitution. One stale instruction to ignore: Cigna’s general credentialing page still lists a OneHealthPort and Medversant option, which is a Washington route and not the Colorado path

Separate door: Evernorth Behavioral Health

Kaiser Permanente Colorado

Behavioral health goes to Carelon, not to Kaiser intake

Usually: Kaiser doesn’t publish a turnaround here, because the gate is network need rather than a queue. A completed Interested Participating Provider Request Form goes to a Provider Experience Consultant. Approved, you get a combined new-practitioner and new-office template for demographics, contracting and credentialing. Declined, your information stays on file with a stated reason
The published behavioral health route: Carelon Behavioral Health, for providers in Colorado Springs, Pueblo, Cañon City and Northern Colorado and the surrounding areas
The route people miss: Kaiser Permanente Insurance Company choice products in Colorado reach providers through the First Health network under a Participating Provider Tier, with First Health running its own credentialing. The card says Kaiser, the network access doesn’t

Separate door: Carelon Behavioral Health

Select Health

Intermountain’s Colorado entrant, mid-sized by design

Usually: no published turnaround. Select Health describes a contracting and credentialing process supported by local Colorado provider representatives
CAQH: yes, and Select Health says it will work with you through credentialing
Why it’s worth asking about: Select Health joined Colorado for the 2024 plan year and is one of the six carriers offering 2026 individual coverage. Its Value network is deliberately mid-sized rather than broad, covering 19 counties from Denver and Boulder out to Mesa, Pueblo and Routt. A mid-sized network is exactly where a behavioral health prescriber can be genuinely additive

Rocky Mountain Health Plans

Three separate contracts inside one name

What it actually is: a UnitedHealthcare company doing triple duty. RMHP is one of the six carriers in the 2026 individual market, it is the Region 1 RAE, and it operates the PRIME Medicaid MCO. Holding one does not give you the others
Route: new network requests and credentialing run through the UnitedHealthcare Get Started and Get Credentialed paths, so expect the Optum route for behavioral health. Confirm at submission
A live stale page: UnitedHealthcare’s own Colorado Community Plan page still describes members as assigned to one of seven Regional Accountable Entities. That’s Phase II language and it has been wrong since July 1, 2025. Verify RAE facts against HCPF, not against a carrier page

Denver Health Medical Plan

Commercial network closed to new contracts

Right now: Denver Health Medical Plan states that its provider network is closed to new contract agreements and that it reviews network needs on a routine cycle. Re-check before anyone puts it in a proposal
Two faces: its individual and Marketplace line is one of the six carriers in Colorado’s 2026 individual market, and Elevate Medicaid Choice is one of the two full-risk Medicaid MCOs. Behavioral health for Elevate members is managed by Colorado Access
Documentation note: its provider manual still directs practitioners to the retired Colorado Health Care Professional Credentials Application. In practice that means CAQH, attested, with the plan authorized

Carelon Behavioral Health

Infrastructure, not a plan you can buy into

How to apply: Carelon moved its intake. New enrollment requests from individuals, groups, and providers joining a group all go through the Carelon payer space in Availity, so you have to be registered with Availity first
Already contracted: adding a line of business, adding a location in a new state under a tax ID you already hold, or changing a tax ID is an Amendment Request, not a new contract. That’s the reach principle in practice
Timeline: Carelon publishes a five-step process and no standard turnaround, and states that submitting documentation does not mean inclusion in its networks
What we check: exactly which Colorado plans your Carelon participation reaches. That mapping changes and it isn’t published in one place

What Colorado law does and doesn’t give you

The most misquoted thing in this state

The statute is genuinely strong. C.R.S. 10-16-705.7 gives a carrier seven calendar days to send a written receipt, ten days to tell you an application is incomplete and say what’s missing, sixty days to conclude credentialing, and ten more to notify you of the outcome. Miss the seven-day receipt and the carrier must treat the applicant as participating no later than day 53. The Commissioner of Insurance enforces it and has to investigate after more than one complaint
And it does not reach a nurse practitioner. The section defines its subject as a physician, and defines physician by reference to the Medical Practice Act at article 240 of title 12. An advanced practice prescriber sits outside that definition. A physician-owned practice can rely on the clock. A PMHNP cannot, and we won’t pretend otherwise in a proposal
No any-willing-provider rule. C.R.S. 10-16-107.7 stops a carrier discriminating against a provider acting within their scope, but says expressly that it doesn’t require a carrier to contract with anyone willing to accept the plan’s terms. Network need governs
No back-pay provision. Colorado has no statute paying you for care delivered while credentialing runs, the way Washington and Illinois do. Sequencing is the whole defense here

Medicare and Health First Colorado, including RAE contracting, are scoped and priced separately from a commercial package. One Colorado demand-side note worth knowing while you pick panels: the Colorado Option standardized plan, required of every carrier in the individual and small-group markets under HB21-1232, gives members $0 mental and behavioral health office visits and $0 substance use disorder office visits. A behavioral health panel with no member cost-sharing behind it fills differently from one with a specialist copay.

Carry a plan we didn’t list? Add it.

Colorado Taft-Hartley trusts from the building trades and UFCW-affiliated funds, self-funded employer plans through a TPA, the First Health tier behind Kaiser Permanente Insurance choice products, BHASO safety-net work through Signal Behavioral Health Network or Rocky Mountain Health Plans. You name the plan, we find the real route. Some of these aren’t contracts you apply for at all, and a BHASO is a separate funding stream we scope on its own rather than folding into a Medicaid package. There’s also a forum most solo practices don’t know exists: HCPF runs a Behavioral Health Independent Provider Network Collaborative specifically for independent behavioral health providers, as distinct from community mental health centers and FQHCs. You don’t need to know the plumbing. We do.

What we need from you

Send these once and we can start.

You give us this in one intake. Then we fill out the applications. No passwords, no patient information, and nothing gets submitted until you’ve read it and signed.

Your individual NPIPlus a Type 2 if you bill under an entity. Colorado adds a wrinkle: HB 18-1282 requires organization providers to obtain and use a unique NPI for each service location and provider type enrolled in the interChange, so a multi-location practice may need more Type 2 NPIs than it expects.
Active Colorado license and DEAPlus your controlled-substance certificate. Anthem wants a current license and DEA or CDS certificate in every state where you provide services before it will call a file complete.
CAQH attested and authorizedYou attest it. We keep it current and authorize each payer. In Colorado this is effectively universal since the state’s own credentials application was repealed in March 2023.
Delegated interChange portal accessSo we can prepare your Health First Colorado enrollment and each RAE or MCO application. No password sharing. Confirm the email and mailing address on file too, because that’s where HCPF sends revalidation notices about six months ahead, and set inactive any delegates who have left the practice.
Entity name, EIN and W-9One per tax ID. HCPF asks for IRS documentation showing the legal name and TIN with a group enrollment and can use it to speed screening. A new EIN is treated as a change of ownership here: you re-apply, sign a new participation agreement, disenroll the old Health First Colorado ID, and get a new NPI.
Bank verification for EFTA W-9 plus a voided check or a bank letter signed and dated within the last six months.
Malpractice certificateNaming you. Evernorth publishes $1 million per occurrence and $3 million aggregate for physicians and psychiatric nurses with prescriptive authority, and Anthem wants current coverage as part of a complete file.
Five years of work historyMonth and year, with any gap explained. Anthem names this specifically, and it is one of the most common reasons a clean-looking file gets returned instead of worked.
Every Colorado location, by countyRAE contracts follow your brick-and-mortar location. A practice with sites in more than one region should contract with each RAE covering a site, and this is how we decide which of the four to sequence first for you.

Two live items to plan around. PNC Bank acquired First Bank effective June 22, 2026, so any Health First Colorado provider who banked with First Bank has a new account and routing number and has to update EFT in the portal or payments stop landing. And Colorado revalidates Health First Colorado and CHP+ providers at least every five years, with HCPF emailing about six months ahead. Claims from providers past their revalidation due date are being denied. The revalidation link stays on your portal account for six months past the due date and then turns into a reenrollment link, which is a slower path, so the address on file is doing more work than most practices realize.

Colorado may also want the practice entity itself licensed, separate from your own clinical license. It’s called a behavioral health entity license, issued by the Behavioral Health Administration under 2 CCR 502-1 with the statute at C.R.S. 27-50. Colorado is unusually crisp about the line: a provider organization becomes licensable at ten or more full-time-equivalent licensed or certified professionals, and contractors count toward that. Four things pull a smaller practice back in, and they’re easy to trip: holding a BHA controlled substance license to stock medications, doing DUI or DWAI or court-referred substance use work, offering any residential or overnight service, or having previously held an OBH or BHA substance use license or a community mental health center designation. The written exclusion at C.R.S. 27-50-101(4) covers services delivered under your own professional practice act “on the provider’s own premises,” and that last phrase is worth a second look for a practice that is entirely telehealth. We flag it, we don’t answer it. We ask about your service mix at intake and confirm which side you’re on before it can hold up a payer contract. We don’t tell you whether you need a license, we don’t publish the requirements, and we don’t file it for you. If you research this yourself, use January 1, 2024 as the date licensing moved to the BHA. Guides written earlier point you at CDPHE or the Office of Behavioral Health, and neither handles it now, and the rules have been amended three times since, most recently effective January 1, 2026.

How it works

You answer once. We do the paperwork.

Buy the package

Published price and scope. No call needed.

One intake

Short and guided. It asks more only where your answers call for it.

We fill it out

Your interChange enrollment, each RAE application, and every commercial application, prepared from what you told us.

You review and sign

Read it, change anything, sign. Nothing goes out until you say so.

We submit and track

Every purchase includes Command Suite, so you can see where each payer application stands, what we’re working on, what’s waiting on a payer, and what we still need from you.

What we commit to

If something we delivered does not work the way we said it would, we fix it at no charge for 30 days after delivery, including one stabilization review. That covers our own work. A new request, another payer or provider, a change of scope, or a new build is quoted separately. You will not get an invoice for correcting our mistake.

Everything we set up is built for the practice you are growing into, not only the one you have today. Adding a provider, a location, or another payer should be a configuration step rather than a rebuild, and the automations and workflows we deliver are sized with that headroom from the start. When the engagement ends you own the accounts, the documentation, and the systems, and they keep running without us.

Questions we get

Colorado credentialing questions

Which Colorado RAE do I need to contract with?

The one that covers where your patients live, and often more than one. Since July 1, 2025 there are four instead of seven: Rocky Mountain Health Plans in Region 1, Northeast Health Partners in Region 2, Colorado Community Health Alliance in Region 3, and Colorado Access in Region 4. Members are assigned by the location of their primary care provider, or by home address if they don’t have one, and they can’t request a different RAE. Reattribution runs quarterly, so a patient’s RAE can change without the patient doing anything. HCPF encourages behavioral health providers to contract with more than one, and each RAE is contractually required to maintain a statewide behavioral health network, which is a better opening than most states give you.

Does Colorado’s 60-day credentialing law cover a nurse practitioner?

By its terms, no. C.R.S. 10-16-705.7 is a strong statute: seven calendar days to acknowledge receipt, ten to flag an incomplete application, sixty to conclude credentialing, and if the carrier misses the seven-day receipt it has to treat the applicant as participating by day 53. But the section defines its subject as a physician, and defines physician by reference to the Medical Practice Act at article 240 of title 12. An advanced practice prescriber isn’t reached by that definition. A physician-owned practice can rely on the clock directly. We won’t promise it to a psychiatric nurse practitioner, and you should be careful with anyone who does. It’s still worth knowing, because it sets the pace carriers built their Colorado processes around.

A Colorado payer asked for the Colorado Health Care Professional Credentials Application. Where do I get it?

You don’t. That form, 6 CCR 1014-4, was repealed effective March 17, 2023, along with the rule that made it mandatory. Several Colorado payer documents still name it by title, including at least one provider manual we read this month. What the instruction now means in practice is a complete, attested CAQH profile with that payer authorized to pull it. Every major Colorado payer we verified runs on CAQH, and Optum states outright that CAQH participation is required for credentialing in this state.

Can a Health First Colorado patient pay me cash if I’m not contracted with their RAE?

No, and this is the part that surprises people. C.R.S. 25.5-4-301 makes it illegal to bill a Health First Colorado member for a covered service. So if you aren’t contracted with that member’s RAE, you can’t bill the RAE and you can’t bill the patient. A single case agreement negotiated with the RAE ahead of time is the exception. That’s why RAE contracting isn’t an optional second phase in Colorado. It decides who you’re allowed to see, and a practice that enrolls with the state and stops there has a Medicaid credential it can’t use.

How does a behavioral health provider join Kaiser Permanente in Colorado?

Usually through Carelon Behavioral Health, not through Kaiser’s general provider intake. Kaiser Permanente Colorado’s own provider page directs behavioral health providers in Colorado Springs, Pueblo, Cañon City and Northern Colorado to Carelon, while general community-provider interest goes to a different inbox. There’s also a second route people miss: Kaiser Permanente Insurance Company choice products in Colorado reach providers through the First Health network under a Participating Provider Tier, so a First Health contract can put you in front of some Kaiser choice members without a direct Kaiser agreement. And don’t carry the Oregon assumption that Kaiser is closed across the border. Colorado is a different plan with a different door.

Is Colorado an any-willing-provider state?

No. C.R.S. 10-16-107.7 bars a carrier from discriminating against a provider acting within the scope of their license, and that matters. But the same section says outright that it does not require a carrier to contract with any provider willing to accept the plan’s terms. Network need still decides. Optum, Aetna, Colorado Community Health Alliance and Carelon each say a version of this in their own words: an application is not a promise of a contract. Which is exactly why panel selection and sequencing carry more weight here than filing speed does.

What is a BHASO, and is it the same as a RAE?

Different thing, same map, which is why it gets confused. Behavioral Health Administrative Service Organizations were created by HB22-1278 and launched July 1, 2025 on the same four regions as the ACC Phase III RAEs, so the county lists are identical. The awardees aren’t: Rocky Mountain Health Plans holds BHASO Region 1 and Signal Behavioral Health Network holds Regions 2, 3 and 4. A BHASO administers state and federal safety-net funding for uninsured and underinsured Coloradans through the Colorado LIFTS network. It isn’t the payer for a Health First Colorado member’s routine outpatient behavioral health, and a RAE contract is not a BHASO contract. If safety-net work is part of your model, it’s a separate conversation and we scope it separately.
