Washington DC Behavioral Health Credentialing and Medicaid Enrollment

Q: Isn't DC's prompt pay law a credentialing deadline?

No, and the distinction is worth being precise about. D.C. Code 31-3132 says a health insurer reimburses a clean claim within 30 days, owes interest at 1.5 percent monthly from day 31 through day 60 and 2 percent from day 61 through day 120, and must allow at least 180 days from the date of service to file. Every word of that is about claims you submit once you are already in network. It says nothing about how long a carrier can take to credential you, and it does not pay you for anything delivered while credentialing runs. Useful when a payer is slow with your money. Not something to plan a launch around.

Q: What is the Healthy DC Plan, and does my Medicaid contract cover it?

It is the District's Basic Health Program under Section 1331 of the ACA, federally approved in September 2025 and live January 1, 2026, run by the DC Health Benefit Exchange Authority with DHCF and DISB. It picked up roughly 16,000 residents whose Medicaid eligibility ended December 31, 2025, mostly childless adults and caregivers between 138 and 200 percent of the federal poverty level, with no monthly premium and no out-of-pocket cost for covered care from participating providers. Three carriers offer it: AmeriHealth Caritas DC, MedStar Family Choice and CareFirst. Your existing participation is usually the door, but we confirm the exact network each carrier uses rather than assuming. Two operational traps: behavioral health is covered differently than under Medicaid, and a Medicaid ID will not confirm Healthy DC Plan enrollment because everyone got new member IDs. Verify through the carrier, not the Medicaid portal.

On August 1, 2026, Wellpoint DC leaves DC Medicaid and roughly 50,000 members move to AmeriHealth Caritas DC. DHCF gave notice on July 2. The general managed care roster goes from three plans to two, which changes the order you file in. If you have a Wellpoint DC application in flight, it needs re-routing to AmeriHealth Caritas DC.

DC payers and timelines

Where the delays actually happen

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

DC has no regional puzzle. Every plan covers the whole District, so none of the waiting here is about geography. It’s stacked instead. DHCF enrollment gates the plans, because MedStar Family Choice won’t start credentialing until you hold an active DC Medicaid provider number. And since March there’s a second registration on the claims side that isn’t enrollment, doesn’t look like it matters, and quietly decides whether a payment shows up.

Credentialed›contracted›loaded›connected›payable

Two tracks

One city, four Medicaid doors, and a commercial book that spans three jurisdictions.

DC Medicaid is mid-change, with a plan leaving and a claims system that turned over in March. The commercial side is steadier and reaches further than most people expect, because the contracts here were built for a metro rather than for a state.

DC Medicaid

Enroll with DHCF first. Then contract the plans that are staying.

Most beneficiaries sit in a citywide plan under the DC Healthy Families Program, with a separate plan for children and youth on SSI. A fee-for-service layer remains for people outside managed care and for the specialty behavioral health services the District never moved into the MCO contracts.

What happens on August 1, 2026Wellpoint DC exits the DC Medicaid managed care program. DHCF gave notice on July 2, 2026. Close to 50,000 enrollees are automatically assigned to AmeriHealth Caritas DC, with a continuity of care window from August 1 through October 31 and member switching allowed through January 31, 2027. Do not start a new Wellpoint DC application. DHCF’s transmittal tells rendering providers to treat referrals and prior authorizations issued before August 1 as valid through October 31, whether or not you’re contracted with the receiving plan, and makes Wellpoint responsible for covered services rendered through July 31. Wellpoint also carried the DC Healthcare Alliance and the Immigrant Children’s Program, and DHCF’s notice speaks only to the Medicaid managed care program, so whether those lines end too is an open question we confirm with the plan rather than guess at. The plan was renamed from Amerigroup DC on July 1, 2025, so older directories carry both names.

The roster after the exitAmeriHealth Caritas DC and MedStar Family Choice DC, both citywide, both carrying DC Healthy Families, the Alliance and the Immigrant Children’s Program. HSCSN, owned by Children’s National, serves the Child and Adolescent SSI Program and is a different population rather than a smaller version of the others. If you only have room for one DC Medicaid contract this year, AmeriHealth is it, purely on what it absorbs.

How you enrollThrough the PDMS portal at dcpdms.com, which Maximus operates for the District. The online application covers the federal screening requirements, and PDMS carries a shorter application type for providers who only order, refer or prescribe. DHCF comes first regardless of which plans you want, because MedStar Family Choice states plainly that you must hold an active DC Medicaid fee-for-service provider number before it will credential you.

The claims-side step people skipOn March 2, 2026 DHCF moved fiscal agent and claims payment from Conduent to Gainwell Technologies and stood up a new claims system. Fee-for-service billers register at medicaid.dc.gov, and electronic submitters also complete trading partner registration plus testing and certification before production. Keying claims directly into the web portal skips the electronic testing step, which is worth knowing for a small practice. None of this is enrollment, and skipping it doesn’t fail loudly.

The behavioral health split, still unresolvedDC planned to fold behavioral health into the MCO contracts on April 1, 2024, paused that carve-in in February 2024, and has not published a new date. So the split stands. Specialty behavioral health, meaning the Mental Health Rehabilitation Services array and the certified substance use disorder levels of care, is delivered by providers certified by the Department of Behavioral Health and billed fee-for-service. A private-practice prescriber usually lives on the MCO side plus fee-for-service enrollment. We confirm which side each of your services bills to before anything is filed.

Commercial

CAQH isn’t a preference here. It’s the law.

CareFirst runs this market as one book across Maryland, DC and Northern Virginia. A typical opening set is CareFirst first on share alone, then UnitedHealthcare through Optum and Aetna, with Cigna queued until the Evernorth pause lifts.

The uniform form statuteUnder D.C. Code 31-3252, from the 2002 Uniform Credentialing Form Act, an insurer or its credentialing intermediary must accept the uniform credentialing form as the sole application to become credentialed or recredentialed. DISB designates the CAQH Provider Application as that form, with penalties at 31-3253. So a stale CAQH profile doesn’t stall one file in DC. It stalls every commercial file at once.

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. CareFirst wants attestation every 120 days and directory information confirmed with CareFirst every 90 days, and Aetna, Cigna and Evernorth all run on a 120-day attestation cycle too.

One CareFirst decision to make before you applyCareFirst requires everyone in the same practice to participate in the same networks. So BlueChoice versus the Regional Participating Preferred Network is a practice-level decision, not something each clinician picks. Getting that settled first avoids unpicking it later. CareFirst also brought behavioral health and substance use in-house from Magellan effective April 1, 2018, so there’s no carve-out vendor on that one.

Behavioral health has its own door at the othersUnitedHealthcare’s is Optum, through Provider Express. Cigna’s is Evernorth. Aetna handles behavioral health itself but on a separate request for participation. Starting on the medical form at those three is the common way to lose weeks in this market.

The federal workforce changes the mathFEP, the Blue Cross federal employee plan, rides your CareFirst participation rather than a separate federal contract. Most other FEHB plans, including GEHA, Compass Rose, the Foreign Service Benefit Plan and NALC, rent a national carrier’s network, so a UnitedHealthcare, Aetna or Cigna contract often reaches those members with no extra application. We confirm the rented network per plan rather than guessing.

DC commercial payers

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

These are typical ranges from a complete application. DC law puts no clock on any of them, so these are each carrier’s own published process. We track them rather than promise them.

CareFirst BlueCross BlueShield and CareFirst BlueChoice

One book across Maryland, DC and Northern Virginia

Usually: CareFirst doesn’t publish a standard turnaround, and DC law puts no decision clock on credentialing. Plan on about 60 to 120 days from a complete file, with recredentialing every three years
Why it does the most work here: about 3.3 million members across the region and over 90 percent regional provider participation. If you already hold CareFirst through a Maryland or Virginia practice, you’re inside the same system rather than starting a third one
How to file: CAQH only, no paper. You need a CAQH ID, CareFirst authorized on your profile, and the CareFirst questionnaire matching your provider type. Attestation every 120 days, directory confirmation with CareFirst every 90
Behavioral health: in-house since April 1, 2018, when CareFirst took it back from Magellan. No carve-out vendor to apply to, which makes this the simplest behavioral door in the District
Watch: the whole practice participates in the same networks, so choose between BlueChoice and the Regional Participating Preferred Network at the practice level. FEP members come through this contract

Optum Behavioral Health (UnitedHealthcare)

Initiated on Provider Express

Usually: about 60 to 120 days from a complete application
Why it matters here: UnitedHealthcare carries a large share of the region’s employer business and is one of three carriers in the District’s small group market. It’s also the network several FEHB plans rent
Behavioral health door: Optum, started through the Join Our Network flow on Provider Express. This is a separate network and contract from core UnitedHealthcare medical, and applying through the medical side is the common mistake that costs weeks
Reach: one contract covers every state you’re licensed in, so a DC contract plus Maryland and Virginia licenses reaches the whole metro without more paperwork

Separate door: Optum Behavioral Health

Aetna

Sits behind several federal employee plans

Usually: about 60 to 120 days from a complete file, with an eligibility answer on network need inside 45 days. Recredentialing generally every 36 months
Sequence: request for participation, then a network need evaluation, then credentialing pulled from CAQH, then contract finalization
Watch: behavioral health uses Aetna’s separate behavioral health request for participation. Aetna credentials behavioral health itself rather than through a carve-out vendor, but the form is still a different one
Why it’s worth more here than the group business suggests: Aetna sits behind several federal employee plans in this market

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 has signaled reopening after September 1, 2026. The pause is national, not a DC decision. Facilities can still apply, and anything filed before June 1 keeps processing
Once reopened: Evernorth says the full process can take up to about 90 days
CAQH: Evernorth asks for your CAQH ID on its behavioral forms and expects re-attestation every 120 days
Our read: we queue Cigna rather than presenting it as available today, and tell you the wait. Optum is the usual substitution

Separate door: Evernorth Behavioral Health

Kaiser Permanente Mid-Atlantic States

Largely closed, and worth confirming rather than targeting

Usually: no published turnaround. The gate is network need rather than a queue
Why we treat it as confirm-first: Kaiser is one of the two carriers that have anchored DC’s individual marketplace since it opened and covers a meaningful slice of DC-area employers, but it runs an integrated model here. Care goes through the Mid-Atlantic Permanente Medical Group and Kaiser’s own centers, so it generally isn’t an open panel a private behavioral health practice joins
Housekeeping: Kaiser retired its old provider site during 2026 and the Mid-Atlantic community provider page moved onto its main member domain, so an older bookmark just redirects

What DC law does and doesn’t give you

The most confused pair of statutes in this market

The form is settled by law. D.C. Code 31-3252 requires an insurer or its credentialing intermediary to accept the uniform credentialing form as the sole application for credentialing and recredentialing, DISB designates the CAQH Provider Application as that form, and 31-3253 carries the penalties. That’s stronger than most states manage
The clock is not. The statute sets no decision deadline. Maryland and Virginia both have one, and Virginia’s even deems an application complete 30 days after receipt unless the carrier says otherwise. A provider working across all three jurisdictions has three different answers, and DC’s is the weakest
Prompt pay is about claims, not credentialing. D.C. Code 31-3132 gives an insurer 30 days on a clean claim, interest at 1.5 percent monthly from day 31 through day 60 and 2 percent from day 61 through day 120, and at least 180 days from the date of service to file. That protects your money after you’re in network. It does nothing while you’re waiting to get there, and it doesn’t pay you for care delivered during credentialing
No back pay. DC has no statute paying you for services delivered while a credentialing application is pending. Sequencing is the whole defense

Medicare and DC Medicaid, including PDMS enrollment and the MCO contracts, are scoped and priced separately from a commercial package. Humana exited the employer group commercial market in a phase-out announced in 2023, so treat Humana in DC as Medicare Advantage business rather than a commercial group conversation.

Carry a plan we didn’t list? Add it.

The Healthy DC Plan, the DC Healthcare Alliance, the Immigrant Children’s Program, federal employee plans beyond FEP like GEHA, Compass Rose, the Foreign Service Benefit Plan and NALC, self-funded employer plans through a TPA. You name the plan, we find the real route. Most of these aren’t contracts you apply for. The FEHB plans rent a national carrier’s network, FEP rides your CareFirst participation, and the Alliance and Immigrant Children’s Program run through the same MCOs as DC Healthy Families, though we confirm each program is actually named in your contract rather than assuming one covers all three. The Healthy DC Plan is its own thing: it’s the District’s Basic Health Program, live January 1, 2026, offered by AmeriHealth Caritas DC, MedStar Family Choice and CareFirst. Your existing participation is usually the door, and a Medicaid ID will not confirm a member’s enrollment because everyone got new IDs. 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 a group or entity.
Active DC license and DEAFor your provider type. Tell us about your Maryland and Virginia licenses too. Metro practices usually hold more than one, and the payer contracts already reach across the region, so the licenses are the real project here.
CAQH attested and authorizedYou attest it. We keep it current and authorize each payer. This carries extra weight in DC, because CAQH is the District’s legally designated uniform credentialing form, so one stale profile stalls every commercial file at once.
Delegated PDMS accessSo we can complete your DC Medicaid enrollment and, if you bill fee-for-service, the Gainwell portal registration. No password sharing. Same for each MCO application.
Entity name, EIN and W-9One per tax ID you bill under. The W-9 is also part of the DC Medicaid enrollment documentation.
Malpractice certificateCurrent, naming you, or a carrier-produced roster face sheet.
Five years of work historyMonth and year, with any gap over six months explained. It’s the most common reason a clean-looking credentialing file comes back instead of moving.
Your service mixSo we can tell which of your services bill to an MCO and which stayed fee-for-service. DC paused its behavioral health carve-in and never restarted it, so that split is still live and it decides where a claim goes.

Two dated items to plan around, both falling on August 1, 2026. Wellpoint DC leaves DC Medicaid managed care that day, so any application aimed at that plan belongs with AmeriHealth Caritas DC instead. Separately, if you also hold a Maryland license, Maryland Medicaid is freezing enrollment for CRNP and APRN-PMH provider types in phases on the way to a new portal, with the phase covering your exact provider type falling on the same date. Applications submitted during a hold are returned without processing. These dates can move, so confirm against MDH rather than relying on a summary. And CMS wrote to every state on April 22, 2026 directing them to revalidate Medicaid providers on a two-year plan, so revalidation notices are landing everywhere between now and 2028. DHCF runs screening and revalidation through PDMS on the federal five-year cycle, and after the March fiscal agent change it’s worth confirming your current revalidation date and keeping your address and contacts current in both PDMS and the Gainwell portal.

DC may also want the practice entity itself certified, separate from your own license. The District certifies behavioral health programs through the Department of Behavioral Health: Mental Health Rehabilitation Services providers under 22-A DCMR Chapter 34, free-standing mental health clinics under Chapter 30, and substance use disorder treatment programs under Chapter 63. DC ties this to program-style services and to specific Medicaid behavioral health service lines rather than to ordinary office practice, so a solo prescriber doing outpatient medication management and billing standard professional codes usually isn’t the target. It starts to matter for things like community support teams, assertive community treatment, a free-standing clinic, or a substance use program. The same question also decides billing mechanics, because the DBH-certified services are exactly the ones that stayed fee-for-service when the District paused its carve-in. We ask about your staffing model and service mix at intake and flag it early if it looks like it could apply, then point you to the Department of Behavioral Health. We don’t tell you whether you need certification, we don’t publish the requirements, and we don’t file it for you.

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 PDMS enrollment, each MCO 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

DC credentialing questions

Should I still apply to Wellpoint DC?

No. DHCF gave notice on July 2, 2026 that Wellpoint DC leaves the DC Medicaid managed care program on August 1, 2026. Its enrollees, reported at close to 50,000 people, are automatically assigned to AmeriHealth Caritas DC. A continuity of care window runs August 1 through October 31, 2026, and members can ask to switch through January 31, 2027. Don’t start a new Wellpoint DC application, and if you already have one in flight it needs re-routing. Sequence AmeriHealth Caritas DC first. One thing we won’t guess at: DHCF’s notice speaks to the Medicaid managed care program, and Wellpoint also carried the DC Healthcare Alliance and the Immigrant Children’s Program. Whether the exit ends those lines too is genuinely open, and we confirm it with the plan rather than assuming either way.

Which DC Medicaid plans are left after August 1?

Two general managed care plans instead of three: AmeriHealth Caritas District of Columbia and MedStar Family Choice District of Columbia. Both are citywide and both carry DC Healthy Families, the DC Healthcare Alliance and the Immigrant Children’s Program. Health Services for Children with Special Needs, owned by Children’s National, is separate and serves the Child and Adolescent SSI Program, so it matters more than its size suggests if you treat kids and teens. A fee-for-service layer also remains, both for people outside managed care and for the specialty behavioral health services the District never moved into the MCO contracts.

Does DC law require a payer to credential me within a certain time?

No, and this is the piece people get wrong because both neighbors have one. DC has a strong credentialing law, D.C. Code 31-3252, but it governs the form rather than the clock: an insurer or its credentialing intermediary must accept the uniform credentialing form as the sole application to become credentialed or recredentialed, and DISB designates the CAQH Provider Application as that form, with penalties at 31-3253. So CAQH is the legal front door here, not a payer preference, and a lapsed attestation is a bigger problem in DC than almost anywhere. What the statute doesn’t do is set a decision deadline. Maryland and Virginia both have one. DC doesn’t.

Isn’t DC’s prompt pay law a credentialing deadline?

No, and the distinction is worth being precise about because the two get quoted interchangeably. D.C. Code 31-3132 says a health insurer reimburses a clean claim within 30 days, owes interest at 1.5 percent monthly from day 31 through day 60 and 2 percent from day 61 through day 120, and must allow at least 180 days from the date of service to file. Every word of that is about claims you submit once you’re already in network. It says nothing about how long a carrier can take to credential you, and it doesn’t pay you for anything delivered while credentialing runs. Useful when a payer is slow with your money. Not something to plan a launch around.

Do I have to enroll with DC Medicaid before the MCOs will credential me?

Yes, and one plan says so outright. MedStar Family Choice DC states that a provider must hold an active DC Medicaid fee-for-service provider number before it will credential them. So the order is fixed: enroll with DHCF through the PDMS portal at dcpdms.com, which Maximus operates for the District, then contract the plans. Getting it backwards means an MCO application that sits waiting on something you haven’t filed. Once you’re in the queue, AmeriHealth Caritas DC notifies within 60 calendar days of its credentialing committee or medical director decision, and MedStar Family Choice completes credentialing within 120 days of its notice of intent to process.

What changed with DC Medicaid claims in March 2026?

DHCF moved its fiscal agent and claims payment from Conduent Government Services to Gainwell Technologies and stood up a new claims system, live March 2, 2026. If you bill fee-for-service you register on the new portal at medicaid.dc.gov, and if you submit claims electronically you also complete trading partner registration plus testing and certification before you can go into production. Claims keyed directly into the web portal skip the electronic testing step, which is genuinely useful for a small practice. This registration is separate from enrollment, it doesn’t look important, and it’s a common reason a correctly enrolled provider still isn’t getting paid. Claims to an MCO follow that plan’s own process instead.

I’m licensed in DC, Maryland and Virginia. Do I need three sets of contracts?

On the commercial side, no. CareFirst runs this market as one book across Maryland, Washington DC and Northern Virginia, covering about 3.3 million members with over 90 percent regional provider participation, so if you already hold CareFirst through a Maryland or Virginia practice you’re inside the same system. Aetna, Cigna and UnitedHealthcare are national and one contract covers every state you’re licensed in, and BlueCard reaches Blue members visiting from elsewhere. The gate to a patient in another state is your license there. Medicaid is the real exception: DC Medicaid is its own enrollment and your Maryland or Virginia Medicaid status doesn’t carry over, even though your patients cross those lines every day.

What is the Healthy DC Plan, and does my Medicaid contract cover it?

It’s the District’s Basic Health Program under Section 1331 of the ACA, federally approved in September 2025 and live January 1, 2026, run by the DC Health Benefit Exchange Authority with DHCF and DISB. It picked up roughly 16,000 residents whose Medicaid eligibility ended December 31, 2025, mostly childless adults and caregivers between 138 and 200 percent of the federal poverty level, with no monthly premium and no out-of-pocket cost for covered care from participating providers. Three carriers offer it: AmeriHealth Caritas DC, MedStar Family Choice and CareFirst. Your existing participation is usually the door, but we confirm the exact network each carrier uses rather than assuming. Two traps worth knowing: behavioral health is covered differently than under Medicaid, and a Medicaid ID won’t confirm a member’s Healthy DC Plan enrollment because everyone got new member IDs. Verify through the carrier, not the Medicaid portal.
