MultiPlan (Claritev) Provider Enrollment: The 2026 Guide to Joining the Network, Checking Your Status, and Getting Paid

MultiPlan provider enrollment is the process of credentialing and contracting with one or more networks operated by Claritev Corporation, the company that changed its name from MultiPlan in February 2025. MultiPlan is still the network brand you'll see on member ID cards. The corporate parent is what changed.

This guide covers the parts most credentialing pages skip: what the status tool won't tell you, which phone number reaches the credentialing department, where your claims go after you're in, and how to read a repriced remittance. Every fact below traces to Claritev's published provider materials or federal sources, and MedSole RCM verified each one against the primary document.

MultiPlan Is Now Claritev: What Changed and What Did Not

MultiPlan Corporation became Claritev Corporation in February 2025, and the company now trades on the New York Stock Exchange under the ticker CTEV. You can pull the name change from the company's filings at SEC EDGAR filings.

The rename didn't touch MultiPlan provider enrollment. Claritev still operates the PHCS Network and the MultiPlan Network under those names, and its clients are still required to display an authorized Claritev name or logo on member ID cards and on the explanation of benefits.

For your posting team, one rule covers it. A remittance referencing Claritev and an ID card showing MultiPlan point to the same company, so don't open a duplicate inquiry when the names look mismatched.

What MultiPlan Actually Is: A Leased Network, Not an Insurance Company

MultiPlan is not an insurance company. Claritev doesn't issue policies, determine benefits, approve authorizations, or pay your claims. On its provider support page, Claritev directs providers to contact the patient's insurance company or plan administrator for benefit information, and to send claims to the remittance address on the ID card rather than to Claritev.

MultiPlan provider enrollment gets you into a network that Claritev then leases out. Health plans, third party administrators, self-funded employers, labor management plans, and government agencies all buy that access. Sign one agreement and you reach every client that leases the network.

That structure decides how you get paid. Your claim pays under the terms of whichever plan leased the network, at the network rate, and that plan sets the benefits, the deductible, and the filing deadline.

Before you assume your contract governs a payment, read the card.

Claritev's guidance is to verify eligibility whenever a card shows one of its authorized names or logos, collect the copay or deductible at the time of service, then submit a clean claim following the instructions on the back. You can confirm this on the Claritev provider support page.

PHCS Network vs MultiPlan Network: The Difference That Decides Your Payment

PHCS and the MultiPlan Network are not the same product. Claritev classifies the PHCS Network as its national primary PPO network. It classifies the MultiPlan Network as a nationwide complementary PPO network, the layer plans reach for when a claim would otherwise process outside their own network.

At the claim level, that distinction moves money. Under a primary network arrangement, the plan applies the contracted PHCS rate to a claim it treats as in network. A complementary arrangement works differently, because the plan discounts a claim its own network never covered. The allowable differs, and so does your appeal route.

Claritev groups its networks into five categories. No other credentialing page publishes this list in full.

The company also runs property and casualty networks, including the MultiPlan Workers' Compensation Network, the MultiPlan Auto Medical Network, and the HealthEOS workers' compensation and auto medical networks.

Two more details your front desk should know. Claritev acquired HMA, Inc. in 2011, which brought in the Arizona Medical Network, Rural Arizona Network, and Health Management Network. It acquired Integrated Health Plan the same year and has since folded the IHP Network into its Claritev-branded network.

Give your posting team a two step check. Read the logo on the card, then confirm which network tier the plan is using before anyone posts an adjustment. If you want that check running before the visit instead of after the remittance, verify plan and network status at scheduling.

Should You Join the MultiPlan Network? A Straight Answer

MultiPlan provider enrollment gives you one credentialing process that reaches a large client base. Claritev's clients include insurance carriers, self-insured employers, labor management plans, and government agencies, plus employers who reach the networks through third party administrators, HMOs, and case management firms.

The trade is rate predictability. Because each leasing plan pays under its own terms, you can't forecast a single reimbursement number the way you can with a direct payer contract.

Claritev doesn't publish a public fee schedule. You request yours through the provider portal after your contract is executed, which means you agree to participate before you see the numbers.

Practices that treat this as a volume decision handle it well. If you need a guaranteed rate, price the downside before you sign, and the cost of enrollment delays belongs in that math too.

Not sure whether MultiPlan fits your payer mix? A short conversation about your specialty and your state usually settles it faster than a spreadsheet does. Talk to a MedSole specialist.

The Ways to Apply to MultiPlan, and How Nomination Differs

MultiPlan provider enrollment starts with picking the right path, because a group application and an individual application follow different routes. Choosing wrong sends you back to the beginning.

Claritev's provider portal handles the group case. Portal users can add participating providers to a group, obtain and submit group rosters, and check application and request status without calling anyone. If you're bringing on a second clinician under a tax ID that already participates, that's a portal task, not a new network application.

Nomination isn't the same as application, and conflating the two is why status checks confuse people. A patient, plan, or client asks Claritev to recruit a provider into the network. Claritev then contacts that provider. The provider still has to apply and get credentialed before anything is active.

Group roster changes carry one rule worth writing on a sticky note. Claritev requires the group administrator to submit changes for providers contracted through a group, and it asks you to state whether the update is a change or a full roster replacement.

The registrar email account receives messages only, so nobody replies to an inquiry sent there. Before you decide to run this in house, read what separates a working process from a paperwork service, covered in choosing a credentialing partner.

What MultiPlan Requires Before You Apply

MultiPlan provider enrollment runs on the same document set every commercial payer asks for. Missing one item doesn't pause verification. It stops it.

Two of these deserve extra attention because they cause the most rework.

Your NPI record has to match your application. Verify what's on file at the NPPES NPI Registry before you submit, because a stale practice address there will contradict the address on your application and stall verification while someone reconciles the two.

The W-9 requirement isn't a formality either. Claritev's Government Business Service Center lists a W-9 as required for credentialing application submissions to the Medicare Advantage network, and the same document drives how the leasing plan sets up your payment record.

Claritev also confirms two rights most providers don't know they have. You can review the information the network obtained during credentialing, excluding peer review protected material.

If the network finds a discrepancy in your application, it has to notify you and give you a chance to correct it, either during verification or through the appeal process in the Network Handbook. Both requests go through the provider portal.

Keeping CAQH, NPPES, and your application aligned from the start is the whole job, and it's what CAQH attestation management exists to prevent.

CAQH ProView: Where Credentialing Applications Stall

Most commercial payers pull provider data from CAQH ProView, and a stale profile is the most common reason MultiPlan provider enrollment stalls after a clean submission. Claritev's public provider page doesn't publish a standalone CAQH requirement, so confirm your specific application's requirement with Service Operations at 1-800-950-7040 rather than assuming.

What doesn't change across payers is the failure pattern. CAQH attestation expires on a rolling cycle, and once it lapses your profile stops feeding the payers you've authorized. Verification doesn't pause and wait for you. It stalls.

Fix it in order. Re-attest first, replace expired documents second, then confirm the payer authorization is active. Doing it in the other order means you re-attest a profile that still contains a dead malpractice certificate.

Set a calendar reminder ahead of every attestation deadline rather than waiting for the email. That email lands in whichever inbox created the profile, and that person may have left.

Create and maintain your profile at CAQH ProView. If you want the deadline tracking handled for you, the mechanics are covered in CAQH profile requirements.

How to Submit Your MultiPlan Application, Step by Step

Six steps carry MultiPlan provider enrollment from first submission to a billable effective date. Skip one and the file waits.

Step 3 is where most files die. Claritev states that an application must be accompanied by a completed and signed provider contract. A credentialing form arriving on its own doesn't open a file, and nobody calls to tell you.

Step 5 rewards speed for a reason worth knowing. Claritev routes unresolved problems to a provider service representative and reports that escalated issues close in less than five business days on average. That escalation path only works once your file has a live owner, which happens after you've responded to the first verification request.

Government programs follow a separate lane. For Medicare Advantage participation, credentialing application submissions go to Claritev's Government Business Service Center, which requires a W-9 with the submission, at 1-866-971-7427 or fax 630-799-3587. Commercial network questions go to Service Operations instead.

State Credentialing Forms: When You Can Use Your State's Form Instead

Providers in 20 states can substitute their state's standard credentialing form for the Claritev form, both for initial credentialing and for recredentialing. Claritev hosts every one of those forms on its provider support page.

One condition governs all of them. The state form has to arrive with a completed and signed Claritev provider contract. Submitted alone, it doesn't start anything.

Separate from those forms, Claritev maintains State Law Coordinating Provision exhibits. These are the state mandated contract provisions folded into your agreement where your state requires them.

Claritev publishes an SLCP exhibit for every state, plus the District of Columbia, Puerto Rico, and a federal Medicare Advantage version. The company revises them as state law changes, so the exhibit attached to a contract you signed years ago may not match the current one.

An SLCP exhibit isn't an application. Claritev says so on its own page, and providers who mail one in expecting it to start credentialing wait a long time for nothing.

Running enrollments across several states at once makes state-specific payer enrollment the biggest drain on staff time. For questions about the credentialing process, Claritev points to Service Operations at 1-800-950-7040.

Medicaid networks run on their own track. Start at the Claritev Medicaid resources page instead.

How Long MultiPlan Provider Enrollment Takes, and Why Published Timelines Disagree

Claritev doesn't publish a MultiPlan provider enrollment timeline anywhere in its provider materials. Any source quoting a precise MultiPlan number is quoting someone's experience, not the payer.

That gap explains the contradictory figures you'll find. Search results quote 60 to 90 days in some places and 90 to 180 days in others, because those numbers measure two different clocks.

Across our own commercial enrollments at MedSole, most payers land between 30 and 90 days once a complete file goes in. Commercial credentialing across the industry runs longer, closer to 60 to 120 days, and the difference between those two ranges is almost never the payer. It's whether the file went out complete and whether somebody chased it every week.

Most enrollment delays come down to who's chasing the payer each week. If nobody at your practice owns that job, MedSole contacts payers every seven days until a decision lands, and credentialing runs $99 per insurance across all 50 states. See how enrollment support works.

How to Check Your MultiPlan Nomination Status

Check the status of MultiPlan provider enrollment on the provider nominations page at multiplan.com, and Claritev links to that tool from its provider support page. The same status check runs inside the provider portal, where portal users can check application and request status alongside their other network tasks.

Registering for portal access takes you further than the public tool does. Portal users verify network participation status, submit billing and network inquiries, access client lists, request fee schedules, contracts, and rosters, add participating providers to a group, and update demographic information.

The tool has a real limitation, and knowing it saves you a week. A status screen reports where your file sits. It doesn't report why it's sitting there, which document is missing, or whether anyone has looked at it. For that, you call.

If your organization would benefit from portal training, Claritev runs monthly education sessions for provider groups with registration required, and it posts upcoming session dates on its provider support page.

Why MultiPlan Applications Stall, and What to Do About Each One

A stalled MultiPlan provider enrollment file is rarely a rejection. It's a file waiting on something nobody told you about.

Discrepancies get their own process, and Claritev commits to it in writing. If the network finds a discrepancy in your application, it notifies you and gives you the chance to correct the information, either during verification or through the appeal process in the Network Handbook.

You also hold the right to review what the network gathered about you during credentialing, with peer review protected material excluded.

Use both rights. A provider who requests the credentialing file and finds a wrong malpractice carrier on it has solved a mystery that would otherwise have cost another month. Requests go through the provider portal.

After roughly 30 days with no movement, calling beats waiting. Which means you need the right number, and there are more of them than most practices realize. Tracking these deadlines across a full panel is what recredentialing and revalidation work is built to catch before a file goes quiet.

Every Verified MultiPlan and Claritev Contact, Sorted by What You Need

Calling the wrong line costs 20 minutes of transfers. The numbers below appear on Claritev's own provider pages, which matters because several MultiPlan numbers circulating in search results and AI answers don't.

Two rules govern every written request above. Contract copy and termination requests both have to arrive on your letterhead carrying the contract holder's signature, so a staff email won't move either one. And the registrar email account accepts incoming messages only, which means an inquiry sent there gets filed, not answered.

If someone calls claiming to be from Claritev asking to verify your tax ID or service address, that's a documented practice. Representatives identify themselves as calling from Claritev, and an unanswered call leaves 866-331-6256 as the callback. Verify before you confirm anything, then call that number back rather than a number the caller supplies.

MultiPlan Payer ID and Where Claims Actually Go

Don't send MultiPlan claims to MultiPlan. Claritev's instruction to providers is explicit: send your completed CMS-1500 or UB-04 with your billed charges to the claims remittance address shown on the patient's ID card, and do not send the completed claim form to Claritev.

The payer ID question has a cleaner answer than most billers expect, and it isn't a number you look up once and reuse. Claritev tells providers to refer to the patient's ID card for the payer identification number of the clearinghouse handling that claim.

That ID varies by the plan leasing the network. A payer ID copied from another practice's cheat sheet produces rejections.

Two operational notes belong on your submission checklist. Claritev warns that payers may reject an electronic claim missing an NPI, and it recommends putting the NPI on paper claims even though no rule requires it yet.

On timing, the 30 business day window starts when the payer receives a complete claim containing everything it reasonably requires. State law and your participating provider agreement can both change it.

Route a payment problem to the right place the first time. Claims payment questions go to the payer's customer service department listed on the ID card or on the explanation of benefits. Contract and network problems go to Claritev's Service Operations Department.

Getting electronic claim submission configured against the right clearinghouse payer ID at setup prevents most of these calls. CMS documents the transaction standards at CMS electronic billing.

Verifying Eligibility for PHCS and MultiPlan Patients

Claritev doesn't determine eligibility or benefits, and it can't tell you a patient's deductible. For patient benefit information, the company directs providers to contact the patient's insurance company, human resources representative, or plan administrator, and it points to the telephone number on the back of the ID card.

Precertification works the same way. Claritev recommends that providers always call to verify eligibility and to confirm whether precertification or authorization is required, using the number on the back of the card. Nothing about network participation changes that step.

Collect at the time of service. Claritev's stated expectation is that you verify eligibility whenever a card shows one of its authorized logos, collect any copay, coinsurance, or deductible at the visit, then submit a clean claim following the instructions on the back of the card.

The network tier question is the one most front desks skip, and it decides whether a later adjustment is correct. Running the check before the visit rather than after the remittance separates a collected balance from a write off.

The distinction between eligibility versus authorization trips up new staff. CMS publishes the standard behind these checks at CMS eligibility transaction standard.

Repricing, Underpayment, and Reading a MultiPlan Remittance Correctly

MultiPlan provider enrollment buys you into one Claritev product. Claim repricing is another, and understanding the second one explains most of the remittances that surprise practices.

Claritev publishes its product line on its own website. Under reference based pricing it sells Data iSight, Vistara, and Pro Pricer. Its claims intelligence group sells negotiation services and financial negotiations. The payment and revenue integrity line covers advanced code editing, clinical negotiation, itemized bill review, and diagnosis related group validation.

Payers buy those tools. Your claim can pass through one of them on its way to payment, which is why an allowable sometimes lands below what your fee schedule predicted.

A CO-45 on a MultiPlan claim means the billed charge exceeded the allowed amount and the payer wrote off the difference as a contractual adjustment. The code alone doesn't tell you whether the write off was right.

One question separates a correct adjustment from a recoverable one. Was the allowable calculated against the rate in your executed contract, or against a repriced amount on a claim your contract never covered? Those are different problems with different remedies, and the CO-45 contractual adjustments guide walks through both.

The legal backdrop is worth knowing before you sign. Healthcare Dive reported in February 2025 that the American Medical Association had accused MultiPlan of working with health insurers to underpay providers, and that dozens of related suits were consolidated in an Illinois district court. Becker's Payer Issues reported that Arizona sued MultiPlan and eight health insurers over alleged price fixing.

Those are allegations. The litigation continues, no final ruling has been reported in the sources above, and none of it stops you from enrolling. Claritev has stated that its rename changed no contracts, rates, or payment terms.

What you can do is verifiable. Plans publish in network rate files and out of network allowed amount files under the federal Transparency in Coverage rule, and those files cover Claritev networks.

Pull the file for a plan that sends you volume, benchmark your allowable against it, then take that number into your next contract conversation. Balance billing rules sit on top of all of it, and CMS documents them at CMS No Surprises Act.

One repriced claim is a claim. The same adjustment across 40 claims from one payer is a pattern, and patterns are where the money is.

If repriced claims keep landing from one payer and nobody has time to pattern them, that's what denial management does. MedSole runs it standalone at 4.49% of recovered dollars, or included at no extra charge inside full service RCM at 2.99% of collections. Get a denial pattern review.

Timely Filing on MultiPlan Claims: There Is No Single Deadline

Claritev publishes no national timely filing limit, and any source quoting one number for MultiPlan is guessing. The plan that leased the network sets the deadline.

That follows from the structure. Two patients can both show a PHCS logo while their plans carry different filing windows, because different clients bought access to the same network under different contracts.

Work your aging against the tightest window in your payer mix, not a house default. A 90 day plan and a 180 day plan in the same bucket means the 90 day claims die while your team works the queue in date order.

Deadlines vary the same way across the Blues, which the payer-specific filing deadlines breakdown shows. Consistent AR follow-up services keep the short window claims from aging out.

Staying Enrolled: Recredentialing, Roster Updates, and Directory Accuracy

MultiPlan provider enrollment isn't a one time event. Letting your demographic data drift is the fastest way to lose network status without anyone terminating you.

Claritev doesn't publish a recredentialing cycle length in its provider materials. Confirm yours in your executed agreement rather than assuming an industry default, and note that eight of the 20 states with substitute credentialing forms post a separate recredentialing version.

For Medicare Advantage participants, the directory obligation carries federal weight. CMS requires Medicare Advantage Organizations to maintain information on network adequacy and availability, and Claritev asks every provider in that network to report changes to directory information and panel status. CMS sets out the wider provider requirements at CMS provider requirements.

Group practices have one more rule. Changes for providers contracted through a group must come from the group administrator, and the submission has to state whether it's a change or a full roster replacement. An individual clinician emailing their own address change won't update a group record.

Tracking attestation dates, recredentialing windows, and roster changes across a full panel is administrative work that produces no revenue until it fails, at which point it produces a terminated contract. That's the case for handing it to enrollment support from $99 per insurance rather than staffing it.

Three Different MultiPlan Lanes: Commercial, Medicare Advantage, and Medicaid

MultiPlan provider enrollment in a commercial network does not enroll you in the MultiPlan Medicare Advantage Network. Claritev states this on its Medicare Advantage page: that application request applies to the Medicare Advantage network only, and you may already participate in PHCS, MultiPlan, or HealthEOS under a separate agreement.

The Medicare Advantage lane carries the fact that prevents the most misrouted calls. Claritev states twice on that page that it does not process, reprice, or administer Medicare Advantage claims, and that claims administration and payment are managed by the applicable Medicare Advantage Organization. Payment questions go to the payer on the ID card.

Recognizing the network takes a second look at the card. A Medicare Advantage ID card identifies the Medicare Advantage Organization and the plan, and it may carry the MultiPlan Medicare Advantage logo or the Beech Street Network logo.

Compliance training attaches to this lane and not the others. CMS and your MultiPlan Medicare Advantage Network provider agreement both require anyone contracted to serve Medicare Advantage beneficiaries to complete the applicable compliance and fraud, waste, and abuse trainings. Practices running Medicaid alongside commercial work face a different set of state rules again, covered in state Medicaid enrollment.

Handling MultiPlan Provider Enrollment Yourself vs Using a Credentialing Partner

Plenty of practices handle one MultiPlan provider enrollment in house and do it well. The math changes with volume, with multi state work, and when nobody owns the weekly follow up.

Judge any partner against the same six criteria, whoever you hire.

Price the cost of waiting before you decide. A stalled MultiPlan provider enrollment has a number attached to it.

A provider generating $8,000 a week in billable services who sits unenrolled for eight weeks represents $64,000 in services that can't be submitted to that plan. That revenue isn't delayed. It's gone, because you can't bill retroactively for a period when you weren't participating.

MedSole RCM handles provider credentialing at $99 per insurance and full service medical billing at 2.99% of collections, with no setup fee and no long term contract.

Most billing companies charge 4% to 7%. On $50,000 in monthly collections, that gap works out to roughly $18,000 a year for the same scope of work.

What separates a revenue driving partner from a paperwork service is covered in credentialing partner standards, and the full scope sits on the full-service RCM at 2.99% page.

Enrolling more than one provider, or working across more than one state? The math usually favors handing it off. MedSole runs credentialing at $99 per insurance and billing at 2.99% of collections, and the first conversation costs nothing. Start your enrollment.

MultiPlan Provider Enrollment FAQ

Is MultiPlan an insurance company?

No. MultiPlan, now operating under the corporate name Claritev, is a PPO network operator. It doesn't issue policies, determine benefits, or pay claims. Health plans, TPAs, and self funded employers lease access to its networks, and those plans pay your claims under their own terms.

What is the new name for MultiPlan?

MultiPlan Corporation became Claritev Corporation in February 2025, and the company trades on the New York Stock Exchange as CTEV. The network brands kept their names, so PHCS and MultiPlan still appear on member ID cards and on explanations of benefits.

Are PHCS and MultiPlan the same network?

No. Claritev operates both, but they serve different roles. It classifies the PHCS Network as its national primary PPO network and the MultiPlan Network as a nationwide complementary PPO network. The difference decides which rate applies to your claim.

Is MultiPlan an HMO or a PPO?

Neither, in the sense the question usually means. MultiPlan isn't a health plan, so it doesn't sell HMO or PPO products to members. Claritev operates PPO networks that health plans lease, including primary networks like PHCS and complementary networks like the MultiPlan Network.

How long does MultiPlan credentialing take?

Claritev publishes no official MultiPlan provider enrollment timeline. Across commercial payers, complete applications commonly resolve in 30 to 90 days, while industry wide commercial credentialing often runs 60 to 120 days. A missing document restarts review rather than pausing it, so completeness drives the date more than the payer does.

How do I check my MultiPlan nomination status?

Check the status of an application submitted through the online system on the provider nominations page at multiplan.com, or inside the provider portal, which also shows request status. The tool reports where your file sits, not why. For a reason, call Service Operations at 1-800-950-7040.

How do I add a provider to an existing MultiPlan group?

Use the provider portal. Claritev lists adding participating providers to a group among the portal's functions, along with obtaining and submitting group rosters. Roster changes for providers contracted through a group must be submitted by the group administrator, not by the individual clinician.

What is MultiPlan's payer ID?

There isn't one universal number. Claritev instructs providers to refer to the patient's ID card to obtain the payer identification number of the clearinghouse used for that claim. Because the ID depends on the plan leasing the network, a payer ID reused from another practice produces rejections.

Where do I send MultiPlan claims?

Send your completed CMS-1500 or UB-04 with your billed charges to the claims remittance address printed on the patient's ID card. Claritev states that providers should not send completed claim forms to Claritev, since it doesn't receive or process them.

What is PHCS in medical billing?

PHCS stands for Private Healthcare Systems, and it's Claritev's national primary PPO network. In billing terms, a PHCS logo on a card means the patient's plan is using that network for provider access and rates, while a separate payer adjudicates and pays the claim.

Can I use my state's credentialing form instead?

Providers in 20 states can substitute their state's form for the Claritev form, for initial credentialing and recredentialing. Claritev hosts each form on its provider support page. The form must arrive with a completed and signed Claritev provider contract, or the application never opens.

Does joining the MultiPlan network cost anything?

Claritev doesn't publish an application fee for MultiPlan provider enrollment. Your real cost is staff time: assembling documents, maintaining CAQH, and chasing the payer weekly. Specialty panels differ in their requirements, and behavioral health credentialing carries rules that surgical practices never encounter.

How often do I recredential with MultiPlan?

Claritev doesn't publish a recredentialing cycle in its provider materials, so confirm the interval in your executed agreement. Eight states post a separate recredentialing version of their substitute form, which you can use in place of the Claritev form where your state qualifies.

Who do I call about a MultiPlan claim that paid short?

Call the payer listed on the patient's ID card or on the explanation of benefits, because that payer adjudicated and paid the claim. Contract and network problems go to Claritev's Service Operations Department at 1-800-950-7040, which routes unresolved issues to a provider service representative.

MultiPlan is one payer. Most practices work six or more at once, each with its own portal, timeline, and follow up cadence. If tracking all of them has become somebody's second job, MedSole runs credentialing at $99 per insurance across all 50 states and full service billing at 2.99% of collections.
