UnitedHealthcare Provider Credentialing: How to Join the Network and Stay In It (2026 Guide)

UnitedHealthcare is the payer most practices cannot afford to be out of network with, and it is also the payer where "we applied months ago" most often turns out to mean "we submitted an interest form and nothing else happened." The process is not mysterious, but it has more moving parts than most commercial plans: a separate onboarding tool, a CAQH dependency that varies by state, a behavioral health path that runs through a different company entirely, and a contracting step that people routinely confuse with credentialing.

This guide covers the whole cycle as it stands in 2026: which products you are joining, how to start in Onboard Pro, what CAQH needs to look like first, how Optum handles behavioral health, what UnitedHealthcare verifies and how long it takes, what to do when claims fail after approval, and how to stay in once you are in. Every tool, cycle and requirement below was checked against UHCprovider.com, Provider Express or the UnitedHealthcare Credentialing Plan on the date in the sources section. Where the official material is silent or inconsistent, the guide says so.

UnitedHealthcare's lines of business, and why product matters

"In network with UnitedHealthcare" is not one thing. UnitedHealthcare administers several lines of business, and network participation can differ between them. The provider portal training catalog groups them as commercial plans, Medicare Advantage (including Chronic and Dual Special Needs Plans), Individual Exchange plans and UnitedHealthcare Community Plan, the Medicaid and state-program business (Plans and Products, UHCprovider.com).

Two points follow. First, the participation agreement spells out which products it covers, and the Credentialing Plan states that if a participating provider fails credentialing or recredentialing for any line of business, UnitedHealthcare will unilaterally amend the agreement to remove that line of business (UnitedHealthcare Credentialing Plan 2025-2027, Section 7.3). Second, being loaded for commercial does not load you for Medicare Advantage, Community Plan or Exchange. When a claim denies as out of network for a patient you thought was covered, the product on the member's ID card is the first thing to check.

Credentialing, contracting and the participation agreement

UnitedHealthcare separates the work into two tracks that run in parallel but finish separately.

Credentialing is the peer-review process that verifies your qualifications. It is governed by the UnitedHealthcare Credentialing Plan, which follows NCQA standards plus CMS and state requirements, and ends with a decision by the National Credentialing Committee or a medical director acting under its authority (Credentialing Plan 2025-2027, Sections 3.2 through 3.4). Meeting the criteria "does not create a contract" (Credentialing Plan, Section 7.3).

Contracting is the participation agreement: the products, the fee schedule and the terms. You are not a participating provider, and not entitled to in-network payment, until the agreement is signed by both parties with a specified effective date and your agreement and demographic information are entered into UnitedHealthcare's systems (Credentialing Plan, Section 7.3).

The onboarding page describes three phases inside one tool: credentialing, then contracting, then connecting, where you set up your portal profile (Join our network - Medical providers). UnitedHealthcare may mail a contract shortly after you request credentialing so the two tracks run together. That contract is not an approval. The Credentialing FAQ warns that receipt of the contract "is not a confirmation of an approved credentialing application, authorization to see UnitedHealthcare members or confirmation that you participate in the UnitedHealthcare network" (Credentialing FAQ).

New contract versus adding to an existing group contract

This distinction changes what you submit and how long the back end takes.

• Joining a group that already holds a UnitedHealthcare group contract. The practitioner is credentialed individually and, if approved, added to the existing contract and tax ID. The FAQ says to complete and authorize CAQH, submit through Onboard Pro, and that if approved "we will add the new physician to your group contract and tax ID. You do not need to submit a second request to complete the last step" (Credentialing FAQ). Onboard Pro "will walk you through the process of adding a new in-network provider under an existing group contract" (Join our network - Medical providers). No new fee schedule is negotiated.
• A new practice, a new TIN or a solo practitioner. Credentialing runs the same way, but contracting is a full new agreement that must be generated, signed, countersigned and loaded. Allow up to 60 days for the contract to load after credentialing is approved and a signed contract is received (Join our network - Medical providers; Credentialing FAQ).

One timing rule groups routinely miss: submit the Onboard Pro request "no more than 30 days before your effective date at your practice" (Credentialing FAQ). A request for a physician who starts in four months tends to stall because the location and start date cannot be verified.

Before you apply: CAQH ProView and the document checklist

UnitedHealthcare collects credentialing data through the CAQH Provider Data Portal, formerly branded CAQH ProView, in every state except Minnesota, where the Minnesota Credentialing Collaborative's ApplySmart is also accepted (Credentialing FAQ). The Join Our Network hub adds that CAQH registration is "only required for some states and specialties" and that Onboard Pro "integrates with (CAQH) ProView, in states that require it" (Join our network, UHCprovider.com). In practice, for most licensed independent practitioners in most states, a complete and current CAQH profile is the foundation of the application, and an incomplete one is the most common reason a file goes quiet.

CAQH readiness checklist

Work through this before you touch Onboard Pro.

• The provider has a CAQH ID and the practice manager has access to the profile.
• Every section is complete, with no "in progress" flags.
• UnitedHealthcare is authorized to access the profile, globally or by plan-specific selection.
• The attestation is current. CAQH reminds you every 120 days, and UnitedHealthcare says to "re-attest every 120 days to keep the application and information current" (Credentialing FAQ).
• Practice location, TIN, group name and NPI in CAQH match Onboard Pro and the W-9.
• Uploaded documents are current: malpractice face sheet, state license, DEA or CDS certificate, board certificate if applicable, CV with month-and-year dates.
• Work history covers five years with no unexplained gap over six months.
• Hospital admitting privileges are listed, or a covering arrangement with a participating physician is documented.

Documents UnitedHealthcare asks for

The Credentialing FAQ lists what a complete application contains. Some items are line-of-business specific.

You will also need a One Healthcare ID, the login for the UnitedHealthcare Provider Portal and Onboard Pro (Join our network - Medical providers).

Step by step: joining through Onboard Pro

Onboard Pro is the current onboarding tool on UHCprovider.com, described as the tool that "guides you, step by step, through the credentialing process, prompting you for more information when needed," with an email reference number on submission and a dashboard to check status 24/7 (Join our network, UHCprovider.com). The steps below are for an individual medical practitioner; behavioral health, facilities and ancillary providers follow the paths covered later.

1. Confirm the specialty routes to UnitedHealthcare and not an affiliate. The Credentialing FAQ routes behavioral health to Optum Behavioral Health, routine vision to the UnitedHealthcare Vision network, dental to the dental benefits affiliate, and chiropractic, outpatient physical, occupational and speech therapy and alternative medicine to Optum's physical health program (Credentialing FAQ). If you are in one of those groups, Onboard Pro is the wrong door.
2. Create or locate the One Healthcare ID. The practice administrator should hold it, with the credentialing coordinator added as a user, so status visibility survives staff turnover.
3. Finish CAQH first. Complete, attested within the last 120 days, UnitedHealthcare authorized, documents current.
4. Sign in to Onboard Pro and enter the identifying data. The tool asks for legal name, business name, TIN, state and lines of business to determine next steps (Join our network, UHCprovider.com). Choose the products deliberately; this is where commercial-only versus commercial plus Medicare Advantage plus Community Plan is set. Multiple state requests can be submitted at once (Join our network - Medical providers).
5. Answer the prompts and upload what is asked. Onboard Pro tells you immediately if something is missing. Respond inside the tool.
6. Record the email reference number. Every later status inquiry will ask for it, with the provider's full name, NPI and TIN (Credentialing Plan, Section 8.2).
7. Watch the dashboard. It shows real-time status of every request and, for facilities, projected completion dates for contracting and credentialing (Join our network - Hospitals and facilities). Check weekly and answer information requests within days.
8. Expect primary source verification and committee review. Once the application is complete, UnitedHealthcare performs primary source verification, then presents the request to its credentialing committee (Join our network - Medical providers). Files that meet every criterion can be approved by a medical director; files with an issue go to the full committee (Credentialing Plan, Section 3.4).
9. Handle the contract. For a new contract, review products and fee terms, sign and return promptly. For an addition to an existing group contract, there is no new agreement; the practitioner is added to the group's TIN once approved (Credentialing FAQ).
10. Confirm the load, then set up the portal. Verify the provider appears under the correct TIN and products, complete My Practice Profile, and only then schedule UnitedHealthcare members as in network.

If UnitedHealthcare is not accepting applications for your specialty or geography, it will notify you and close the request (Credentialing FAQ). The medical provider page describes a reassessment request for closed markets when you provide specialized care, are acquiring an in-network practice, or have other warranting circumstances (Join our network - Medical providers). Reassessment is a business-need argument, not an appeal of a credentialing denial, and should read like one.

Behavioral health: Optum and Provider Express

Mental health and substance use disorder practitioners do not credential through Onboard Pro. UnitedHealthcare's FAQ directs them to Optum Behavioral Health via providerexpress.com (Credentialing FAQ). The behavioral network is contracted through United Behavioral Health and, in California, U.S. Behavioral Health Plan, California, under the separate Optum/United Behavioral Health Credentialing Plan (Initial Credentialing for Individual Clinicians FAQ, Provider Express).

Provider Express offers four entry points (Join Our Network, Provider Express):

• Individually credentialed clinicians, for solo clinicians or clinicians in a group without an Optum group agreement.
• Group with individually credentialed providers, for groups holding an Optum group agreement. Optum's eligibility criteria include all eligible clinicians agreeing to participate, claims submitted under the practice TIN with the individual identified, central intake and billing, cross-coverage for urgent appointments, and a minimum of five providers to be credentialed (Group with individually credentialed providers, Provider Express). In non-delegated groups every clinician still needs individual credentialing; delegated groups work through their delegation specialist.
• Group with agency credentialed providers, for community mental health centers, FQHCs, rural health centers, opioid treatment programs and similar licensed entities.
• Facilities, for programs offering inpatient, residential, partial hospitalization or intensive outpatient levels of care.

The individual clinician path

Individuals complete the New Provider Request Form after registering for Provider Express and using the Join Our Network feature in the menu (Individually Credentialed Clinicians, Provider Express). Key requirements from Optum's page and FAQ:

• CAQH participation is required in most states, and the CAQH ID goes on the form. The CAQH authorization must be to United Behavioral Health / U.S. Behavioral Health Plan, not only UnitedHealthcare. CAQH data must match the form; where fields auto-populate from CAQH and cannot be edited, log out, fix CAQH, and return (Initial Credentialing for Individual Clinicians FAQ).
• The W-9 must be signed, dated and completed for the practice, with a TIN matching the form.
• Missing documents go out through DocuSign; slow responses are a named cause of delay.
• Medicare-eligible clinicians must answer yes to the Medicare question to have Medicare networks included; Medicaid-eligible clinicians must supply the Medicaid ID. Medicaid networks are not available in all states.
• Some specialties require a Clinician Specialty Attestation Form.

Optum's FAQ says initial credentialing "can take between 30-120 days to fully complete," covering primary source verification, quality review, committee review and data loading, and that data loading can take an additional 5 to 30 business days from the approval letter date. Optum asks that the contract be signed and returned within 7 days (Initial Credentialing for Individual Clinicians FAQ). Status is checked in Provider Express under My Practice Info, My Network Status, Check Initial Credentialing Status (Individually Credentialed Clinicians, Provider Express).

For integrated groups, a psychiatrist may credential medically through Onboard Pro and behaviorally through Provider Express, each with its own effective date. Track both.

Facilities, hospitals and ancillary providers

Facility credentialing is organizational rather than individual. A facility includes hospitals and ancillary providers such as home health agencies, skilled nursing facilities, behavioral health centers, FQHCs, rural health centers, free-standing surgical centers and multispecialty outpatient surgical centers (Credentialing Plan, Section 2).

What a facility must show

Each facility must meet four criteria (Credentialing Plan, Section 7.1):

1. Current required licenses.
2. General liability and professional liability insurance at the limits in UnitedHealth Group's provider guidelines, or a state-approved alternative.
3. A clean Medicare and Medicaid sanctions review, clear of OIG, GSA and CMS Preclusion List actions, regardless of the line of business contracted.
4. Accreditation from a body recognized in the plan's Attachment C, or a satisfactory alternative. An unaccredited facility needs a site visit with satisfactory results; a CMS or state quality review no more than three years old can substitute if the facility supplies the final report or letter.

Facilities are recredentialed at least every 36 months, and staff can stop processing or recommend termination for facilities that fail to submit a complete application after multiple documented requests (Credentialing Plan, Section 7.2).

How hospitals and facilities apply

Hospitals and facilities start in Onboard Pro with a One Healthcare ID and should have ready proof of malpractice and general liability insurance, a W-9, an email address, the physical address with suite number and the ZIP+4 (Join our network - Hospitals and facilities). Two rules on that page matter for planning. Facilities seeking participation in multiple states submit a separate application for each state. And a facility contract does not credential its clinicians: "All individual health care professionals associated with any participating UnitedHealthcare network of hospitals and facilities must go through the credentialing and contracting process." The Credentialing Plan's exception is narrow: hospital-based professionals whose services are incidental to the facility's generally are not credentialed, unless UnitedHealthcare directs members to them or a regulator requires it (Credentialing Plan, Section 4.1).

Ancillary providers

Ancillary providers and centers, which UnitedHealthcare lists as ambulatory surgery centers, dialysis, DME, home health and hospice, infusion and specialty pharmacy, diagnostic testing, radiology, sleep facilities and similar, mostly follow a different path: complete the service-specific digital questionnaire, then sign in to the portal and submit it through chat with the Provider Onboarding team. Some categories, including ASCs, portable X-ray and laboratories, use Onboard Pro. UnitedHealthcare says it will decide within 15 business days for most categories, longer for laboratories, and that a declined application stays on file for one year before you can reapply (Join our network - Ancillary providers and centers). The same page shows that some ancillary networks are closed or limited at any given time, so check it before completing a questionnaire.

What UnitedHealthcare verifies

UnitedHealthcare states that its credentialing standards are set by NCQA and CMS, that it collects application data through CAQH and state platforms, and that it uses a credentials verification organization, Verisys (formerly Aperture), for primary source verification (Credentialing FAQ). "Primary source verify" means confirming directly with the educational, licensing or accrediting entity, or an NCQA-approved equivalent, that what you supplied is correct and current (Credentialing Plan, Section 2).

The 2025-2027 plan, effective March 1, 2025, requires the application and attestation to be no more than 180 days old at the decision date and primary source verifications no more than 120 days old, and adds verification of state Medicaid exclusion lists where applicable (Updated 2025-2027 credentialing plan effective in March, UHCprovider.com; Credentialing Plan, Section 4.2). An application that drags past six months can therefore require a fresh attestation, and stale verifications are redone.

(All elements from UnitedHealthcare Credentialing Plan 2025-2027, Section 4.2.)

The committee "will not make any decision on an Applicant without a completed Application," may delay action while a hospital, licensing board or government agency investigation is pending, and may deny where a discrepancy cannot be resolved (Credentialing Plan, Section 3.4).

Timeline and how to check status

UnitedHealthcare's own timing statements are not perfectly consistent across documents, so plan with ranges. The current medical provider page says credentialing "generally takes up to 45 calendar days or more to complete once we have a completed application and all required information" (Join our network - Medical providers). The 2024 Credentialing FAQ gives a shorter figure for the same step; both note that the clock depends on response times from schools, boards and hospitals, and both allow up to 60 days for a signed contract to load after approval.

A clean individual application to join an existing group contract often lands in the 45 to 90 day range from submission to a usable effective date; a new contract for a new TIN commonly runs 90 to 150 days including negotiation and loading. Those are planning ranges from practice experience, not UnitedHealthcare commitments, and one unanswered information request can push any file past them.

Checking status

• Onboard Pro dashboard. Real-time status of every enrollment request (Credentialing FAQ). The source of truth for "did they receive it."
• Portal chat. Available 24/7 in the UnitedHealthcare Provider Portal (Credentialing FAQ). Have the reference number, provider name, NPI and TIN ready.
• Your applicant rights. Every applicant may ask for status, review the information gathered including primary source results, and correct errors. UnitedHealthcare notifies you when verified information varies substantially from what you submitted, and corrections must be submitted in writing within 30 days. You are entitled to notice of the decision within 30 calendar days of the committee's decision (Credentialing Plan, Section 8.2).
• Provider Express. For behavioral health, use My Network Status and Check Initial Credentialing Status (Individually Credentialed Clinicians, Provider Express).

If a file shows no movement for three weeks with nothing outstanding on your side, open a chat, cite the reference number, and ask whether the application is complete, whether verification is in progress, and whether anything is pending from a third party. "It's in process" is a prompt to ask those three questions again, in writing.

What goes wrong: stalls, denials and post-approval claim problems

Most UnitedHealthcare problems fall into three buckets: the application never became "complete," the committee found something, or credentialing succeeded and the contract or load did not.

Why applications stall

• CAQH not authorized, not attested or not matching. The file cannot be pulled, or it conflicts with Onboard Pro. UnitedHealthcare names CAQH completeness and 120-day re-attestation as the delay you can prevent (Credentialing FAQ).
• Submitted too early. Requests more than 30 days before the start date cannot be tied to a verifiable location (Credentialing FAQ).
• W-9 mismatch. Legal name or TIN differs from Onboard Pro or the group contract (Initial Credentialing for Individual Clinicians FAQ).
• Unanswered information requests. Files sit when no one watches the dashboard, and processing can cease after multiple documented requests go unanswered (Credentialing Plan, Section 3.4).
• Slow third parties. Supplying diploma and certificate copies up front helps.
• Stale verifications. A file past the 120-day verification or 180-day attestation window must be refreshed (Credentialing Plan, Section 4.2).
• Closed market or closed ancillary category. The request is closed with notice rather than processed.

Why applications are denied

The committee can deny for any unresolved discrepancy, and the plan lists specific disqualifiers: a material restriction on the license in a practice state, an exclusion or termination for cause from Medicare, Medicaid or CHIP without an OIG waiver, a failed site visit, unacceptable malpractice history, and a denial or termination within the prior 24 months (Credentialing Plan, Section 4.2). If denied, you are notified in writing with the reasons and with information on what you can do if you disagree (Credentialing FAQ; Credentialing Plan, Section 3.5). Appeals are permitted to the extent a credentialing authority requires them, and the process is communicated with the notice (Credentialing Plan, Section 8.3). Respond within the stated window.

Post-approval claim problems and how to fix them

Credentialing approval is not what makes claims pay; the load is. Participation begins only when the agreement is signed by both parties with a specified effective date and the demographic information is entered into all pertinent systems (Credentialing Plan, Section 7.3). These are the failures that show up as denials.

Do not release UnitedHealthcare claims on the strength of an approval letter. Release them when the portal shows the practitioner under the right TIN, products and location, with an effective date on or before the first date of service.

Staying in network: recredentialing, attestation and demographic updates

Getting in is half the job. Three maintenance cycles keep you in, on three different clocks.

Recredentialing every 36 months

Licensed independent practitioners and facilities are recredentialed at least every 36 months (Credentialing Plan, Sections 5.1 and 7.2). UnitedHealthcare "automatically starts the process when you approach the 3-year recredentialing cycle," and if your CAQH or ApplySmart application is complete and attested every 120 days "there's nothing you need to do" (Credentialing FAQ). The corollary: UnitedHealthcare "won't notify you when the recredentialing process begins" as long as your data is current, unless a state requires notice. If the data is not current, notice comes from UnitedHealthcare or from Verisys, with reminders (Credentialing FAQ). A practice that ignores a Verisys email because it does not recognize the name is a practice about to lose network status.

At recredentialing, UnitedHealthcare re-applies the initial criteria except that education for non-board-certified practitioners and work history are not re-verified. It obtains three years of malpractice history, reviews any quality-of-care concerns from the cycle, checks compliance with the participation agreement including improvement action plans, and performs a site visit where a state requires it (Credentialing Plan, Section 5.2). Failing to complete recredentialing can end eligibility to participate (Credentialing FAQ).

Recredentialing can also be triggered off-cycle: a practitioner "may be subject to initial credentialing standards" when moving from delegated to direct credentialing or when a contracting change flags the status as needing an update, and a specialty change requires training documentation that is primary source verified (Credentialing Plan, Sections 5.1 and 5.2). Separately, you must inform UnitedHealthcare immediately of any material change: loss or restriction of privileges, prescribing ability, accreditation, ability to perform professional duties, an OIG sanction, a GSA debarment or a licensure restriction. Failure to do so can result in termination (Credentialing Plan, Section 3.6). UnitedHealthcare also reviews complaint history at least every six months between cycles (Credentialing Plan, Section 9).

CAQH attestation every 120 days

This is the credentialing data feed. CAQH prompts every 120 days, and UnitedHealthcare relies on that cadence to avoid initial delays and to make recredentialing automatic (Credentialing FAQ). Put the date on a shared calendar and assign an owner.

Demographic verification every 90 days

This is the directory and claims data feed, and it is a contractual requirement separate from CAQH. Contracted providers are "required to verify your demographic information every 90 days" (Provider data updates and attestation, UHCprovider.com). The elements include the phone number for each location, accepting-new-patients status, the locations where the provider actually takes appointments, the USPS address with suite and accessibility, email, affiliated group name, office hours, specialties, languages, licenses, telehealth services and hospital affiliations.

UnitedHealthcare offers several ways to submit and says one is enough:

• My Practice Profile in the UnitedHealthcare Provider Portal, where you view, update and attest to the demographic information members see, including addresses and hours, panel status, telehealth, NPI, languages, ages and genders served, and hospital and group affiliations (My Practice Profile, UHCprovider.com). It supports roster upload for organizations managing many TINs (Provider data updates and attestation).
• CAQH Provider Data Portal, which updates profiles in real time for every payer you have authorized, with a group version for delegated groups (Provider data updates and attestation).

Maintenance checklist

• CAQH re-attested every 120 days, with malpractice and license renewals uploaded before they expire.
• Demographic data attested every 90 days through My Practice Profile or CAQH.
• Recredentialing date (36 months from the last decision date) on the calendar for every practitioner and facility, with a 6-month lead.
• Any email or letter from Verisys treated as a UnitedHealthcare credentialing notice and answered.
• Material changes reported immediately.
• New locations, terminated practitioners and TIN changes submitted as they happen.
• Product participation reviewed annually against the practice's payer mix, especially Medicare Advantage and Exchange.

Fast Track Credentialing runs these cycles for practices that would rather not staff them; details are on our credentialing services page. Fast Track Credentialing is an independent credentialing service and is not affiliated with or endorsed by UnitedHealthcare.

Frequently asked questions

Do I need CAQH to credential with UnitedHealthcare?

In most states and for most licensed independent practitioners, yes. UnitedHealthcare gathers credentialing data through the CAQH Provider Data Portal, with Minnesota also accepting MCC ApplySmart (Credentialing FAQ). A CAQH ID and authorization alone are not enough; you still submit a request through Onboard Pro so UnitedHealthcare knows you want to join and can pull the profile (Credentialing FAQ).

How long does UnitedHealthcare credentialing take?

UnitedHealthcare's current page says up to 45 calendar days or more once the application is complete, and asks you to allow up to 60 days for the contract to load after approval (Join our network - Medical providers). Plan on 45 to 90 days for a clean addition to an existing group contract and longer for a new contract. Optum behavioral health quotes 30 to 120 days plus data loading (Initial Credentialing for Individual Clinicians FAQ).

Can I see UnitedHealthcare members once I receive the contract?

No. The contract may arrive before credentialing is finished, and UnitedHealthcare states that receiving it is not confirmation of approval or of network participation. Both credentialing and contracting must be complete, and the agreement and your data must be loaded, before you are in network (Credentialing FAQ; Credentialing Plan, Section 7.3).

What is the difference between adding a provider to our group contract and getting a new contract?

An addition rides on the existing group agreement: the practitioner is credentialed, then added to the group's contract and TIN with no second request and no new fee schedule (Credentialing FAQ). A new contract requires a full participation agreement to be generated, signed and loaded, which is where most of the extra time goes.

Does a hospital or facility contract cover the clinicians who work there?

No. Every individual health care professional associated with a participating hospital or facility must go through credentialing and contracting, unless they fall into the narrow hospital-based exception for services incidental to the facility's own services (Join our network - Hospitals and facilities; Credentialing Plan, Section 4.1).

Where do behavioral health providers apply?

Through Optum Behavioral Health on Provider Express, not Onboard Pro. Individual clinicians complete the New Provider Request Form after logging in, authorize United Behavioral Health / U.S. Behavioral Health Plan in CAQH where the state requires CAQH, and track status under My Network Status (Individually Credentialed Clinicians, Provider Express).

How often does UnitedHealthcare recredential, and will they tell me?

At least every 36 months for practitioners and facilities (Credentialing Plan, Sections 5.1 and 7.2). UnitedHealthcare starts the process automatically and, if your CAQH or ApplySmart data is complete and attested every 120 days, does not send advance notice unless the state requires it. If your data is not current, notice comes from UnitedHealthcare or Verisys (Credentialing FAQ).

How do I check the status of my application?

Use the Onboard Pro dashboard for real-time status, or open a chat in the UnitedHealthcare Provider Portal with the reference number, provider name, NPI and TIN (Credentialing FAQ; Credentialing Plan, Section 8.2). For Optum, use Check Initial Credentialing Status in Provider Express.

How do I update an address, panel status or phone number?

Submit once through My Practice Profile in the portal or through the CAQH Provider Data Portal, then attest. Contracted providers must verify demographic data every 90 days regardless of whether anything changed (Provider data updates and attestation, UHCprovider.com).

What if my application is denied?

You are notified in writing with the reasons and with information on what you can do if you disagree, and you have the right to review the information gathered and correct errors (Credentialing FAQ; Credentialing Plan, Sections 3.5 and 8.2). A denial or termination for reasons other than network need can bar reapplication for 24 months (Credentialing Plan, Section 4.2). If you want a second set of eyes on a denial letter or a stalled file, Fast Track Credentialing can review it; start at our pricing and order page or reach the team through our contact form.
