MultiPlan is now Claritev, but providers may still see the MultiPlan, PHCS, HealthEOS, Beech Street, or related network names in contracts, portals, member ID cards, and provider materials. Joining one of these networks is not a single form submission. A practice may need to select the correct network route, complete contracting, submit a credentialing application, resolve verification issues, receive a participation decision, and confirm that every provider, TIN, location, MultiPlan provider credentialing and product is active before treating patients as in network.
This guide explains the current general process for U.S. practices using Claritev's official provider resources. Requirements vary by provider type, network, state, product, and agreement. Claritev controls network participation and credentialing decisions; no outside service can guarantee acceptance, a completion date, reimbursement terms, or a retroactive effective date.
MultiPlan Corporation announced its corporate rebrand to Claritev in February 2025. Claritev's provider handbook still addresses participation through MultiPlan and subsidiaries or network brands such as PHCS and HealthEOS. MultiPlan provider credentialing For operational work, do not assume that Claritev enrollment means the same application for every product. Identify the precise network named in the agreement or application request.
Stage
What It Does
Evidence of Completion
Contracting
Establishes network terms, products, reimbursement arrangements, and provider obligations.
Executed agreement or written contracting confirmation.
Credentialing
Reviews professional qualifications, licensure, history, insurance, disclosures, and eligibility criteria.
Written credentialing or participation decision.
Enrollment
Loads the provider, group, TIN, NPI, locations, specialties, and product relationships.
Portal or written confirmation that the correct records are active.
Billing readiness
Connects participation data with eligibility, claim routing, payer instructions, and practice workflows.
Verified network status and correctly processed early claims.
A complete CAQH profile does not prove network participation. A signed agreement also does not prove that a rendering provider is active at every location. Wait for written confirmation, verify the effective date, and test the operational setup before representing the practice as in network.
Application Track
Use It For
Important Distinction
Commercial PPO networks
Private-market participation involving MultiPlan, PHCS, or HealthEOS.
Use the commercial route identified by Claritev.
Medicare Advantage
Participation in the MultiPlan Medicare Advantage Network.
This application is separate from commercial PPO participation.
Medicaid networks
PHCS Medicaid Network or Texas True Choice participation.
Government-funded networks use a separate request route.
Existing group addition
Adding a provider to an already participating group.
Confirm group name, contract ID, TIN, NPI, and locations.
Facility or ancillary
Organizations rather than individual practitioners.
Use the organizational application and handbook.
Claritev's current practitioner checklist accepts the MultiPlan practitioner application, a mandated standardized state application, or a copy of the full CAQH application. The CAQH Summary alone is not accepted for credentialing. When a state form is used, Claritev states that it must accompany a completed and signed provider contract.
Complete application and a signed Attestation and Release dated within 30 days of submission.
Current professional licenses and DEA information when applicable.
Education, training, specialty, board status, MultiPlan provider credentialing and clinical-practice details.
Work history with month and year dates plus explanations for gaps of six months or more.
Current professional and comprehensive general liability evidence.
W-9 and TIN authorization when the applicant or group does not own the billing TIN.
Current CV and detailed explanations for affirmative professional-history answers.
Complete practice, billing, payment, and mailing addresses; a PO Box should not be used as a practice address.
Required hospital affiliation or admitting privileges for applicable provider types.
Correct group name and contract information when joining through an existing group.
Confirm the correct network and identify the commercial PPO, Medicare Advantage, Medicaid, facility, ancillary, or existing-group route.
Check network fit and contracting status. Determine whether the practice needs a new agreement or is adding a provider to an existing one.
Reconcile legal names, NPIs, taxonomy codes, TIN, W-9, licenses, locations, specialties, and contact details.
Prepare an accepted credentialing application: the MultiPlan form, a permitted state form, or the full CAQH application.
Collect insurance, CV, W-9, TIN authorization when needed, disclosure explanations, licenses, and other requested evidence.
Sign and submit while the Attestation and Release is current, and retain delivery proof.
Track receipt, verification, case numbers, outstanding items, and next follow-up dates.
Respond accurately to discrepancies and requests for clarification.
Confirm participation, effective date, products, locations, provider-to-group links, eligibility workflow, and claim routing.
Claritev does not publish one universal national completion promise for every network and provider type. Timing depends on application completeness, contracting, primary-source verification, committee review, state law, and the network route. State-specific rules can impose their own standards. Treat any general estimate from a third party as planning guidance, not a guarantee.
A useful tracker separates contracting, credentialing, enrollment, and billing activation. Record the submission date, case number, current stage, last contact, missing item, owner, next follow-up date, decision, and verified effective date.
Use the Claritev Provider Portal to check application or request status when the submission was made online.
Confirm whether the contract is complete and whether credentialing has formally started.
Ask whether the application, attestation, insurance, W-9, TIN authorization, work history, or disclosures are incomplete.
Record the representative name, contact date, case number, current stage, and exact next action.
For commercial network credentialing questions, Claritev lists Service Operations at 800-950-7040. Government network contact routes may differ.
Claritev states that practitioners may correct erroneous information submitted for a credentialing application. Applicants may also request access to credentialing or recredentialing information obtained for evaluation, except information protected by peer-review rules. Use the portal or the applicable appeal process and keep proof of every correction.
Problem
Why It Delays the File
Preventive Action
Wrong network route
Commercial, Medicare Advantage, Medicaid, and organizational applications differ.
Classify the product and applicant first.
CAQH Summary submitted
The summary is not an accepted credentialing application.
Submit the full CAQH application or another accepted form.
Old attestation
The signed release falls outside the required freshness window.
Sign immediately before final submission.
TIN mismatch
The W-9, billing TIN, group ownership, and application do not align.
Reconcile the entity and include authorization when required.
Incomplete work history
Missing dates or six-month gaps trigger follow-up.
Build a continuous timeline and explanations.
Expired documents
Licenses, DEA records, or insurance may fail verification.
Renew early and submit current copies.
Missing group link
The provider is not linked to the intended contract or location.
Maintain a provider-to-group-to-location matrix.
Approval assumed too early
Credentialing alone does not prove billing readiness.
Verify the effective date, directory, eligibility, and early claims.
Claritev maintains credentialing and recredentialing programs and periodically updates its criteria. Participating practices should keep licenses, liability coverage, contact information, directory data, tax records, ownership details, locations, specialties, and panel status current. Respond promptly to recredentialing requests and use the Provider Portal to update demographic information, obtain rosters, and manage cases.
Written participation decision and applicable effective date received.
Correct network products and service area confirmed.
Rendering providers linked to the correct group NPI, TIN, locations, and specialties.
Provider directory information reviewed for accuracy.
Eligibility and member ID card workflow documented for staff.
Contract and fee schedule access confirmed where available.
Claim address, electronic routing, and payer instructions verified.
First claims and remittances reviewed for network, enrollment, location, and reimbursement errors.
