Maine Behavioral Health Credentialing and Payer Enrollment

MaineCare never went to managed care. You enroll once through the Health PAS Online Portal and there’s no plan roster behind it, no MCO contracts, nothing to chase. A 2025 bill to bring in three plans, LD 1878, was voted Ought Not to Pass on May 21, 2025 and died. What Maine has instead is a section problem. MaineCare Section 65 doesn’t list prescribers as independent practitioners, so a solo psych NP enrolls under Section 14. Get that one wrong and you’re applying at a door you can’t walk through.

Why Maine is different

Less to chase here, so the wrong door costs you more.

Maine takes work off the front end and puts it into getting the details right. There’s less to chase here than almost anywhere, so the cost of aiming at the wrong door is higher.

Fee-for-service, and nothing behind it

MaineCare, one of the last of its kind
  • MaineCare is fee-for-service statewide. One enrollment reaches every member. There is no plan-by-plan contracting step behind it
  • LD 1878, which would have directed the department to contract with three MCOs from 2029, was voted Ought Not to Pass on May 21, 2025 and died under Joint Rule 310 on May 27. Watch it, don’t plan around it
  • Acentra Health, the organisation people still call Kepro, runs prior authorization, continued stay review and referral management through the Atrezzo portal. That’s authorization plumbing, not a second network
  • You don’t credential with Acentra. You register for Atrezzo once you’re a MaineCare provider

Section 14 or Section 65 decides everything

MaineCare Benefits Manual, Chapter II
  • Section 65.02-1 defines Independent Practitioner as a Licensed Psychologist, Psychological Examiner, LCPC, LCSW or LMFT. Prescribers are not on that list
  • Everything else in Section 65 routes through Mental Health Agencies and Substance Use Agencies licensed under 10-144 C.M.R. ch. 123
  • A PMHNP appears in Section 65 as a Clinician, under APRN-PMH-NP and APRN-PMH-CNS, which is how a prescriber delivers those services inside a licensed agency
  • On your own the door is Section 14, Advanced Practice Registered Nursing Services. Section 14.06 reimburses an independent practitioner at the published Section 90 physician-services amounts

Thirty days, one list, sixty to decide

24-A M.R.S. section 4303(2)(D)
  • Within 30 days of first receiving your application the carrier has to review the whole thing and, if it’s incomplete, return it with one comprehensive list of everything needed
  • Then 60 days to decide a completed application, extendable only by written notice inside those 60 days, with a 180-day outer limit no matter what
  • A carrier that can’t decide inside 60 days has to notify the Bureau of Insurance in writing before the deadline passes, and file a remediation plan where the delay isn’t specific to one application
  • The single-list rule matters as much as the deadline, because it ends the drip of new requests that keeps a file open for months

Paid back to the day your file was complete

24-A M.R.S. section 4303(2-A), and 4303(2)(D) on residency
  • If the carrier credentials you, it has to pay claims for services you rendered before credentials were granted, back to the date your complete application was submitted
  • That makes a genuinely complete first submission worth money, and it’s why we don’t send a partial file to look fast
  • Separately, a carrier may not require a provider to have a home address within the State before accepting an application, which removes an obstacle several other states leave in place for telehealth practices
  • The gate that does apply is a licence where the patient is sitting. Community Health Options puts that on its own network form

Where the delays actually happen

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

Most of the waiting happens in the gaps between these five steps. We work all of them, and we tell you which one you’re actually sitting in.

Two tracks

MaineCare is one application. Commercial is a short list.

Because there are no plans behind MaineCare, it’s often worth sequencing early. It’s one application, not one plus five.

MaineCare

Trading Partner Account first, then the application.

Enrollment is the online Provider Enrollment Application in MIHMS, the Maine Integrated Health Management Solution, submitted through the Health PAS Online Portal. Gainwell Technologies runs enrollment for the state. Step one is a Trading Partner Account on the portal, and without it you can’t submit the application or check claims later. An executed MaineCare Provider Agreement is required before you can participate, and a new agreement is needed for a new enrollment, a re-enrollment or a reactivation. Address changes, added service locations and name changes take an updated agreement instead.

The prescriber question we ask firstDo you want to bill MaineCare, yes or no. If yes, we file the full enrollment. If no but you prescribe, we file NOPR, the free non-billing, ordering, prescribing and referring enrollment, because since September 1, 2025 MaineCare only pays for prescriptions written by an enrolled provider. NOPR doesn’t obligate you to accept MaineCare payment or see MaineCare members. The related claim edits have moved from warn to deny.
Forms you’ll actually see

Trading Partner Account registrationProvider Enrollment ApplicationMaineCare Provider AgreementNOPR enrollmentAtrezzo registration

The authorization layerAcentra Health runs prior authorization and referral management through Atrezzo, covering Section 65 behavioral health and Section 28 children’s services. Two dated changes are live. Since February 2, 2026 a Single Assessment, completed by Acentra’s own licensed clinicians, establishes eligibility for medium to high intensity children’s behavioral health services, and medical providers not on Atrezzo refer through a separate link. And from July 1, 2026 Acentra took over a new referral management process for Sections 65 and 28.
Watch the citations in old plansCrisis Resolution stopped being a Section 65 service after June 30, 2026. From July 1, 2026 MaineCare covers it under Section 66 as Site-Based Crisis Stabilization Services. Anything built on the old Section 65 citation is out of date.
Revalidation and the feeEvery five years for most provider types, three for DMEPOS, with the notice going to the contact and address on file. Changes have to be reported within 10 days and records kept for five years. The application fee rose to $750 on January 1, 2026 to match the CMS amount, charged on new, reactivating and revalidating enrollments and on each added service location. Under Chapter I and 42 CFR 424.514(d) it falls on institutional providers, and individual physicians and non-physician practitioners are excepted, as is anyone who paid it to Medicare, another state Medicaid agency or CHIP in the last 12 months. A solo prescriber enrolling as an individual normally doesn’t pay it, but the exception turns on how you enroll, so we confirm at submission.

Commercial

Anthem is first, and its behavioral door is Carelon.

Anthem holds the Blue licence for Maine and runs the largest network in the state, covering State of Maine employees, the Maine Education Association Benefits Trust and the Maine Municipal Employees Health Trust alongside its own book. After that the list is genuinely short: Harvard Pilgrim, Community Health Options, UnitedHealthcare through Optum, Martin’s Point on the Medicare and TRICARE side, and Aetna and Cigna as employer and national account business.

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. We never ask for your password. Anthem, Harvard Pilgrim, Community Health Options, Optum, Aetna, Evernorth and Martin’s Point all pull from CAQH, and for Anthem you set access to Global so Carelon can see your updates.
The statute names a form it never designatesMaine’s clocks run from a completed application, defined as one containing everything required by the uniform credentialing application used by carriers and providers in this State plus any attachments the carrier requires. The statute doesn’t name that application, and we couldn’t find a Bureau of Insurance rule or bulletin designating one. In practice every Maine carrier we checked works from CAQH, so treat CAQH as the operative file and confirm carrier-specific attachments at submission.
Behavioral health has its own doorCarelon Behavioral Health for Anthem, commercial and Medicare Advantage, including credentialing and recredentialing through the National Provider Service Line. Optum for UnitedHealthcare, through Join Our Network in Provider Express. Evernorth for Cigna. A separate behavioral health request for participation at Aetna. Harvard Pilgrim and Community Health Options handle it inside the plan.
The Optum route that closedPoint32Health brought behavioral health in house in November 2023 and finished on January 1, 2025, when non-contracted behavioral health providers stopped being in network for Harvard Pilgrim commercial members. Maine members got a 90-day continuity-of-care runway. If you used to reach Harvard Pilgrim patients through Optum, that route is closed and you need your own Point32Health behavioral contract. Optum still manages behavioral health for the Stride Medicare Advantage HMO line only.
Seeing patients in other statesAetna, Cigna with Evernorth, and UnitedHealthcare with Optum are national, so one contract each covers every state you’re licensed in, and Anthem reaches out-of-state Blue members through BlueCard. The gate is a licence where the patient is sitting. MaineCare is the exception, because that enrollment is Maine-only and doesn’t travel.

Maine commercial payers

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

These are typical ranges from a complete application, with the 60-day decision requirement in 24-A M.R.S. section 4303 sitting underneath them. Payers control their own timelines, so we track them rather than promise them.

Anthem Blue Cross and Blue Shield in Maine

The largest network in the state, and the one we sequence first
  • Usually: about 90 to 120 days from a complete application, with the statutory 60-day ceiling on a decision once the file is complete and a documented extension route out to 180 days
  • Behavioral health: the door is Carelon Behavioral Health, not the medical network, for commercial and Medicare Advantage alike. Credentialing and recredentialing run through the Carelon National Provider Service Line, with a Maine network integration mailbox. Claims and eligibility run through Availity
  • Bonus coverage: this contract is also how you reach State of Maine employees, the Maine Education Association Benefits Trust and the Maine Municipal Employees Health Trust
  • Watch: set CAQH access to Global, or Carelon can’t see your updates and demographic changes have to go through both systems

Separate door: Carelon Behavioral Health

Harvard Pilgrim Health Care

Point32Health, and the tiered network that reshaped the north
  • Usually: Point32Health says credentialing and contracting generally run about one to two months from a complete application, longer if anything is missing. Credentialing runs through the HCAS process using CAQH
  • Behavioral health: in house since the November 2023 insourcing, completed January 1, 2025. Your old Optum route doesn’t reach these members
  • 2026 network changes: Maine Choice expanded statewide, and Northern Light Health hospitals sit in the Preferred tier of Maine Choice Plus across Aroostook, Hancock, Piscataquis, Penobscot and Somerset counties
  • Watch: a National Access product launched January 1, 2026 using the Harvard Pilgrim network in its five-state region and UnitedHealthcare’s Choice Plus network elsewhere, with no out-of-network benefit

Community Health Options

Maine’s homegrown co-op, based in Lewiston
  • Usually: contract first, then credentialing. Health Options requires a signed participation agreement, or an agreement with an already-contracted entity, before credentialing starts, and you can’t see members until its Credentialing Committee approves you. Its own guidance describes at least 30 days for data entry then up to about 60 business days to finish
  • How it goes in: the Provider Network Request Form to the contracting mailbox, with adds and changes going to the data integrity mailbox. Verisys is the credentialing verification organization and works from the contact listed in CAQH, so that contact needs to be a real person
  • Why it matters: one of the last ACA co-ops still operating and a genuine network here, though its individual-market share slipped about five points during the 2026 open enrollment
  • Watch: the network form asks whether services are telehealth-only and notes you must be licensed in the state the member is located in

UnitedHealthcare and Optum

The only payer here that tells you which counties it wants
  • Usually: 60 to 120 days from a complete application, started through Join Our Network inside Provider Express. CAQH is required for Maine credentialing per Optum’s own Maine page, so get the CAQH ID first
  • Why it’s near the front: Optum accepts MDs, DOs, PAs and RNs with prescriptive authority in all counties, and openly recruits telemental health, medication assisted treatment prescribers, Express Access providers who can see a member within five business days, and EAP providers
  • Rare detail: it names Androscoggin, Kennebec, Lincoln and Sagadahoc counties as priority areas for some provider types. Payers almost never tell you where they want you
  • Watch: this is a separate application from core UnitedHealthcare medical

Separate door: Optum Behavioral Health

Martin’s Point Health Care

Portland, and bigger in its lanes than its size suggests
  • Usually: no published turnaround. Martin’s Point credentials through its own Credentials Committee, so confirm with its network management team at submission
  • What it is: not a commercial group carrier. Its lines are Generations Advantage, one of Maine’s larger Medicare Advantage plans, and the US Family Health Plan, which is TRICARE Prime for military families and retirees in northern New England
  • Why it matters: it credentials nurse practitioners and other prescribers directly rather than through a behavioral vendor, and if your panel skews Medicare-age or military there’s no other route to these members
  • Watch: it was reported as discontinuing at least one plan for 2026, so confirm the current product list before you build around it

Aetna

Hold it for portability, not for Maine volume
  • Usually: a request for participation, an answer on network need within about 45 days, then credentialing pulled from CAQH. Commonly 60 to 120 days end to end
  • Path: behavioral health professionals use Aetna’s separate behavioral health request for participation, not the medical one
  • Set expectations: Aetna isn’t among the carriers selling individual or small group coverage in Maine for 2026, and reporting has it scaling back Medicare Advantage here for 2026, affecting roughly 1,400 members while keeping plans in some southern and central counties. What’s left is mostly large group and national account business

Cigna Healthcare and Evernorth

Paused right now, nationally, and thin here anyway
  • Right now: Evernorth paused new individual and clinic behavioral health applications on June 1, 2026 and has signalled a reopen after September 1. Facilities are exempt and anything filed before June 1 keeps processing
  • Usually: up to about 90 days to join the behavioral network once it’s open
  • Set expectations: Cigna isn’t among the carriers offering individual or small group coverage in Maine for 2026 either, so its presence here is employer and national account business. We sequence the other panels first and queue this one

Separate door: Evernorth Behavioral Health

Don’t build a Maine launch around Mending, formerly Taro Health. It notified the Maine Bureau of Insurance on June 8, 2026 that it will stop offering health insurance in Maine as of January 1, 2027. Roughly 1,100 members keep coverage through the end of their plan year and shop for 2027 in the open enrollment that starts November 1, 2026, and small groups run to their renewal dates. Mending was one of four carriers on CoverME.gov for 2026 and held about two percent of the individual market after expanding into six new counties, so you may well have current Mending patients. The practical point is sequencing: those patients need a different in-network route for 2027, which usually means getting the Anthem, Harvard Pilgrim or Community Health Options contract in place first. Humana is a Medicare Advantage conversation in Maine, not a commercial one. Medicare, Medicare Advantage and MaineCare work is scoped and priced separately from a commercial package.

Carry a plan we didn’t list? Add it.

Maine has several large blocks of covered lives that don’t look like carriers. The State of Maine employee health plan runs on the Anthem network. The Maine Education Association Benefits Trust holds a group contract with Anthem covering roughly 69,000 people, with behavioral health through Carelon and an Anthem-run employee assistance programme behind it. The Maine Municipal Employees Health Trust covers municipal employees across the state on the same network. In all three the Anthem contract is the route, not a separate trust contract, which is one more reason Anthem usually goes first. The US Family Health Plan is TRICARE Prime for military families and retirees in northern New England, and you reach those members through Martin’s Point credentialing rather than a national TRICARE contract, so it’s easy to miss if you only think in big-carrier terms. You name the plan. We find the real route.

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.

  • A yes or no on billing MaineCareIf yes, we file the full enrollment. If no but you prescribe, we file the free NOPR enrollment instead, because since September 1, 2025 MaineCare won’t pay for prescriptions written by an unenrolled provider. NOPR doesn’t obligate you to accept MaineCare payment or see MaineCare members.
  • A plain description of what you plan to billIncluding whether you’re adding intensive outpatient, substance use treatment or agency-style behavioral health. In Maine that answer decides whether you enroll under Section 14 or need an agency route, and whether the practice entity itself needs a DHHS licence. Better settled in intake than mid-application.
  • Your individual NPIPlus the Type 2 if you bill under a group or entity. MaineCare ties the Provider Agreement and every service location to these, so we want them right before the application goes in.
  • Active Maine licence and DEAOptum’s Maine page is explicit that it takes RNs with prescriptive authority, and Community Health Options’ form says you must be licensed in the state the member is located in. That’s the gate for telehealth reach too.
  • CAQH attested and authorizedYou attest it. We keep it current. Anthem, Harvard Pilgrim, Community Health Options, Optum, Aetna, Evernorth and Martin’s Point all pull from it, and Maine’s 60-day clock only starts once the file is complete. For Anthem, set access to Global so Carelon can see your updates.
  • Delegated access to the portalSo we can set up the Health PAS Trading Partner Account and complete the MaineCare enrollment on your behalf, with no password sharing. We also need the mailing address and contact you want on file, because that’s where the revalidation notice goes five years from now.
  • Malpractice certificateThe current declarations page naming you.
  • Entity name, EIN and W-9One per tax ID you bill under.

Depending on what you plan to bill, Maine may want the practice itself licensed, separately from your own licence. The state’s term is a Behavioral Health Organization licence from the DHHS Division of Licensing and Certification under 10-144 C.M.R. ch. 123, and Maine licenses mental health programmes and substance use disorder treatment programmes separately, so a practice offering both would be looking at two applications and two licences. Two places make it concrete. MaineCare Section 65 routes agency-style behavioral health through Mental Health Agencies and Substance Use Agencies holding that licence. And a June 6, 2025 DHHS bulletin states that Section 65 intensive outpatient providers must be licensed under ch. 123, that mental health programmes need medication management on the licence and substance use programmes need medication assisted treatment on it, with 30 calendar days to add it. A solo prescriber doing outpatient medication management under Section 14 usually sits outside all of this, but the line follows the services billed rather than the sign on the door. We ask during intake and flag it early. We don’t give legal advice and we don’t file it for you.

How it works

You answer once. We do the paperwork.

You can buy online without a meeting. Published price, published scope, no call needed unless you want one.

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, starting with what you plan to bill, because that picks your MaineCare section.

We prepare everything

The Trading Partner Account, the MaineCare application and Provider Agreement, Atrezzo access if you need it, and every commercial file.

You review and sign

Read it, change anything, sign. Nothing goes out until you say so, and nothing goes out incomplete, because in Maine a complete file is what starts the clock and the back pay.

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 stand behind

Payer decisions, timing and rates are not ours to promise, and we don’t promise them. Our own work is a different matter. 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. A new request, another payer or provider, a change of scope, or a new build is quoted separately. You won’t get an invoice for correcting our mistake.

Built to keep working after we’re done

Everything we set up is built for the practice you are growing into, not only the one you have today. Adding a provider or a second location should be a configuration change rather than a rebuild. When the engagement ends you own the accounts, the documentation and the systems, and they keep running without us. No lock-in.

Questions we get

Maine credentialing questions

Does MaineCare have managed care plans I need to contract with?
No. MaineCare is fee-for-service statewide, which makes Maine one of the last states where one enrollment reaches the whole Medicaid population. There’s no plan roster behind it and nothing to chase after the state approves you. Managed care was proposed and didn’t pass: LD 1878 would have directed the department to contract with three MCOs with enrollment phasing in from 2029, and the Health and Human Services Committee voted Ought Not to Pass on May 21, 2025, with the bill dying under Joint Rule 310 on May 27, 2025. Treat Maine managed care as something to watch, not something to plan around. What Maine does have is an administrative services layer: Acentra Health, the organisation people still call Kepro, runs prior authorization, continued stay review and referral management through the Atrezzo portal. You don’t credential with Acentra. You register for Atrezzo access once you’re a MaineCare provider.
Should I enroll under MaineCare Section 14 or Section 65?
For a prescriber practising on their own, Section 14. This is the fact that decides a Maine build and it catches people constantly. Section 65.02-1 defines Independent Practitioner as a Licensed Psychologist, Psychological Examiner, LCPC, LCSW or LMFT. Prescribers are not on that list. Everything else in Section 65 routes through Mental Health Agencies and Substance Use Agencies licensed by the Division of Licensing and Certification under 10-144 C.M.R. ch. 123. A PMHNP does appear in Section 65, as a Clinician under the APRN-PMH-NP and APRN-PMH-CNS categories, which is how a prescriber delivers Section 65 services inside a licensed agency. On your own, the door is Section 14, Advanced Practice Registered Nursing Services. Section 14.04 routes psychiatric and psychological services to the Section 90.04 or Section 65 rules and sends prescribers to Section 80 for pharmacy, and 14.06 reimburses an independent practitioner at the published Section 90 physician-services amounts. Aim at the wrong section and you’re applying at a door you can’t walk through.
Do I have to enroll with MaineCare if I only prescribe?
Yes, and there’s a free short form for exactly that. Since September 1, 2025 MaineCare only pays for prescriptions written by an enrolled provider, under the 21st Century Cures Act. If you never want to bill MaineCare and never want to see MaineCare members, you enroll through NOPR, the non-billing, ordering, prescribing and referring pathway. It costs nothing, takes less documentation, and doesn’t obligate you to accept MaineCare payment. Skipping it is how a prescriber finds out at the pharmacy counter that their patients can’t fill anything. The related claim edits have moved from warn to deny, so a billing provider also needs an enrolled ordering or prescribing NPI on the claim.
How long does a Maine carrier have to decide on my application?
Maine wrote one of the better provider-protection statutes in the country. Under 24-A M.R.S. section 4303(2)(D) the carrier has 30 days from first receiving your application to review the whole thing and, if it’s incomplete, send it back with one comprehensive list of everything needed. That single-list requirement matters as much as the deadline, because it stops the drip of new requests that keeps a file open for months. It then has 60 days to decide a completed application, and it can only extend that by written notice inside those 60 days saying the file needs more verification time. Every decision has to be made within 180 days regardless. A carrier that can’t decide inside 60 days has to notify the Bureau of Insurance in writing before the deadline passes and, where the delay isn’t specific to one application, file a remediation plan. The Bureau publishes the extension application form. It’s the carrier’s obligation, not our promise, and the clock only runs from a complete file.
Will a Maine carrier pay me for work I did while credentialing was pending?
Yes, if it ultimately credentials you. Under 24-A M.R.S. section 4303(2-A) a carrier has to pay claims for services you rendered before credentials were granted, back to the date your complete application was submitted. That makes a genuinely complete first submission worth real money in Maine, and it’s exactly why we don’t send a partial file to look fast. The right depends entirely on dated evidence of when a complete application landed, so we keep the paper trail rather than filing and hoping. Note the condition in the sentence: the carrier still has to credential you, and that decision belongs to the carrier.
Can a Maine carrier turn me down because I don’t live in Maine?
No. 24-A M.R.S. section 4303(2)(D) says a carrier may not require that a provider have a home address within the State before accepting an application. For a telehealth practice licensed in Maine but based somewhere else, that removes an obstacle several other states leave in place. The gate that does apply is licensure where the patient is sitting. Community Health Options makes the point on its own network form, which asks whether services are telehealth-only and notes you must be licensed in the state the member is located in. Every other Maine carrier works the same way.
Which carriers actually sell coverage in Maine?
The bench is short and getting shorter, which is worth knowing before you plan a panel. Four carriers sold individual coverage on CoverME.gov for 2026: Anthem, Harvard Pilgrim, Community Health Options and Mending, formerly Taro Health. Mending notified the Maine Bureau of Insurance on June 8, 2026 that it will stop offering health insurance in Maine as of January 1, 2027, so roughly 1,100 members keep coverage through their plan year and shop for 2027 in the open enrollment starting November 1, 2026. Aetna and Cigna aren’t selling individual or small group coverage in Maine for 2026, so their Maine presence is employer and national account business. Martin’s Point is Medicare Advantage and the US Family Health Plan rather than commercial group. Fewer carriers means fewer contracts to chase, and it also means the ones you hold matter more.
Do you need my CAQH password?
No, and we won’t ask. We’re added as an authorized practice manager, which lets us keep your practice data current and authorize payers. You complete and attest your own profile, and you sign anything that needs your signature. Anyone asking a provider for their CAQH password is doing it wrong. Maine’s statute measures its clocks from a completed application, defined as one containing all the information required by the uniform credentialing application used by carriers and providers in this State, plus any attachments the carrier requires. The statute doesn’t name that application and we couldn’t find a Bureau of Insurance rule or bulletin designating one, so we say that plainly rather than pretending otherwise. In practice every Maine carrier we checked works from CAQH. For Anthem, set CAQH access to Global so Carelon Behavioral Health can see your updates.
