Overview

UnitedHealthcare (UHC) is the largest commercial health insurer in the United States, serving approximately 50 million members as of 2025 through employer-sponsored, individual, Medicare Advantage, and Medicaid managed care plans. As a subsidiary of UnitedHealth Group, UHC operates across all 50 states and represents a significant portion of the patient population at most behavioral health treatment centers.

Behavioral health services for UnitedHealthcare members are managed through Optum Behavioral Health, which handles utilization management, prior authorization, and clinical review functions. This carve-out arrangement means that treatment centers often interact with Optum rather than UHC directly when it comes to clinical authorizations, though credentialing and claims are typically handled through UHC’s own provider network systems.

For treatment center operators, UnitedHealthcare is often one of the highest-volume payers in their mix. Understanding the distinction between UHC’s administrative processes and Optum’s clinical management processes is essential for maintaining clean claims, timely authorizations, and steady cash flow.

Behavioral Health Coverage

UnitedHealthcare covers a comprehensive range of behavioral health services across multiple levels of care. Covered levels include medically managed detoxification, residential treatment, partial hospitalization programs (PHP), intensive outpatient programs (IOP), standard outpatient treatment, and medication-assisted treatment (MAT). Coverage specifics vary based on the member’s plan design, with employer-sponsored plans often having different benefit structures than individual marketplace or Medicaid managed care plans.

Medical necessity determinations for substance use disorder (SUD) treatment are based on the ASAM Criteria, which evaluate patients across six dimensions including acute intoxication potential, biomedical conditions, emotional and behavioral conditions, readiness to change, relapse potential, and recovery environment. For mental health conditions, UHC uses the Level of Care Utilization System (LOCUS) to determine appropriate placement. Clinicians should be thoroughly familiar with both frameworks, as authorization denials frequently stem from documentation that fails to address the specific criteria dimensions.

Authorization requirements vary by level of care. Outpatient services generally do not require prior authorization, though some plan designs may require notification. Intensive outpatient, partial hospitalization, residential, and detox services almost universally require prior authorization before admission or within the first 24 to 48 hours for urgent admissions. Concurrent review is required at regular intervals, typically every 5 to 7 days for residential treatment and every 2 to 4 weeks for PHP and IOP.

Credentialing and Provider Enrollment

UnitedHealthcare uses CAQH ProView as its primary credentialing verification source. To begin the credentialing process, you must first complete and attest your CAQH ProView profile, then submit an application to join the UHC provider network. Applications can be initiated through the UHC Provider Portal or by contacting the UHC provider recruitment team for your region.

The credentialing process typically takes approximately 60 to 90 days from the submission of a complete application, though timelines can vary. Required documents include current state licenses for the facility and all clinical staff, professional liability (malpractice) insurance certificates, accreditation documentation (CARF or Joint Commission if applicable), DEA registrations for prescribing providers, a completed W-9 form, and evidence of compliance with state-specific operational requirements.

Facility credentialing requires additional documentation beyond individual practitioner credentialing. You will need to provide your facility license, proof of accreditation, organizational NPI, Medicare and Medicaid certification if applicable, a current program description, and staffing information. UHC may also conduct a site visit as part of the credentialing process.

Recredentialing generally occurs every 36 months. Keep your CAQH ProView profile current with re-attestation every 120 days to avoid credentialing lapses. Any changes to your facility address, ownership, licensure, or key personnel should generally be reported to UHC within 30 days, though specific notification timelines may vary.

Verification of Benefits (VOB)

Verifying benefits for UnitedHealthcare members is a critical step that should occur before every admission. The primary methods for verification include the UHC Provider Portal at uhcprovider.com, calling the provider services number on the back of the member’s insurance card, and electronic eligibility verification through EDI 270/271 transactions via your clearinghouse.

When conducting a VOB, confirm the following information: whether the member’s plan includes behavioral health benefits, which specific levels of care are covered, the member’s current deductible and how much has been met, coinsurance or copay amounts for each level of care, out-of-pocket maximum status, any visit or day limitations, whether services are carved out to Optum Behavioral Health, prior authorization requirements, and whether the member has out-of-network benefits.

Pay particular attention to whether behavioral health benefits are managed by Optum. When Optum manages the behavioral health benefit, authorization requests must go through Optum’s systems rather than UHC directly. The provider portal will typically indicate when a carve-out applies.

For members with employer-sponsored plans, benefits can vary significantly between employers even though the insurance carrier is the same. Never assume that one UHC member’s benefits are the same as another’s. Always verify benefits on a per-patient basis and document the date, time, reference number, and representative name for every VOB call.

Prior Authorization Requirements

Prior authorization is required for most behavioral health services above the outpatient level of care. This includes detoxification, residential treatment, partial hospitalization, and in many cases intensive outpatient programs. Authorization requests are reviewed by Optum Behavioral Health clinical staff using ASAM Criteria for SUD and LOCUS for mental health.

To submit a prior authorization request, you can use the UHC Provider Portal, call the Optum Behavioral Health prior authorization line, or submit through an electronic authorization platform. The initial request should include a comprehensive biopsychosocial assessment, diagnosis codes, the recommended level of care with clinical justification, a treatment plan with measurable goals, and documentation addressing all relevant ASAM or LOCUS dimensions.

Concurrent review is a standard part of the authorization process. For residential treatment, expect reviews approximately every 5 to 7 days. For PHP, reviews typically occur every 7 to 14 days. For IOP, concurrent review intervals are generally every 2 to 4 weeks, though intervals can vary by plan. Have updated clinical documentation ready for each review, including progress notes, treatment plan updates, and evidence of the patient’s response to treatment.

If an authorization request is denied, you have several options. First, request a peer-to-peer review, which allows your treating clinician to speak directly with the Optum medical director who made the denial decision. Peer-to-peer reviews should be requested promptly, as there are time limits. If the peer-to-peer does not result in an overturn, you can file a formal appeal. UHC typically allows approximately 180 days from the date of denial to file an internal appeal, though timeframes may vary by state and plan type.

Claims and Billing

UnitedHealthcare accepts claims through electronic submission (preferred) and paper claims. Electronic claims should be submitted using the standard 837I (institutional) or 837P (professional) formats through your clearinghouse. Paper claims use the CMS-1500 form for professional claims and UB-04 for institutional claims.

The timely filing limit for UnitedHealthcare is generally approximately 90 days from the date of service or discharge for most commercial plans, though this may vary by plan type and state. Some plan types, including Medicaid managed care products, may have different timely filing requirements. Always check the specific plan’s requirements to avoid denials based on untimely filing.

Common denial reasons for behavioral health claims include lack of prior authorization, medical necessity not established, timely filing exceeded, incorrect coding, and coordination of benefits issues. Providers should confirm that authorization is obtained before or during the admission, documentation clearly supports medical necessity for the billed level of care, claims are submitted with accurate CPT, HCPCS, and revenue codes, and coordination of benefits information is up to date.

For denied claims, UHC provides a multi-level appeal process. First-level appeals should be submitted in writing with supporting clinical documentation. If the first-level appeal is unsuccessful, a second-level appeal can be filed. External review through an independent review organization is also available for certain types of denials, particularly those involving medical necessity determinations. Keep detailed records of all appeal submissions, including dates, reference numbers, and clinical documentation provided.

Payer Operations Quick Reference

The operational data billers need mid-task — phone numbers, payer IDs, filing limits, and addresses — with the entity distinctions that make UnitedHealthcare confusing: UHC (the insurer), Optum Behavioral Health (the clinical manager), and United Behavioral Health/UBH (the legal entity that appears on many EOBs and contracts). Phone numbers and payer IDs change; confirm against uhcprovider.com ↗ and providerexpress.com ↗ before relying on any value here.

Provider phone numbers

Phone-tree shortcuts are intentionally omitted: UHC and Optum change their IVR menus without notice, and we only publish tree navigation we have verified first-hand with a date.

Payer IDs and EDI

• Primary UHC payer ID: 87726 (professional and institutional) — covers most UHC commercial plans and many affiliated products. Plan-level exceptions exist, so confirm against the member card and your clearinghouse payer list before submitting.
• UHC-affiliated entities (UMR, Surest, student resources, some Community Plan states) use separate payer IDs — always match the ID on the member card against your clearinghouse payer list rather than defaulting to 87726.
• Behavioral claims managed by Optum/UBH are generally still submitted under the UHC payer ID shown on the member card; the carve-out affects authorization routing, not necessarily claim routing.
• ERA/EFT enrollment: enroll through Optum Pay and your clearinghouse for 835 remittances.

Timely filing limits

A wrong payer ID rejection does not stop the filing clock — resubmit immediately, and keep the original submission report as proof of timely filing. Cross-payer comparison table: /denial-code-timely-filing.

Claims and appeals addresses

• Electronic first: 837P/837I via clearinghouse under payer ID 87726 is the default; paper should be the exception.
• Paper claims address: varies by plan and region — use the address on the member ID card or the UHC Provider Portal claims section.
• Appeals: the appeals address is plan-specific and printed on the denial letter or EOB/PRA; UHC typically allows ~180 days from denial for internal appeals (state/plan variation applies). For behavioral health denials, request a peer-to-peer with the Optum medical director before or alongside the formal appeal — expedited review is available when the patient is in active treatment at detox, residential, PHP, or IOP levels of care.

Credentialing contacts

• Start with CAQH ProView ↗ (keep attestation current every 120 days), then apply via the UHC Provider Portal; facility contracting is handled by regional network management — request it through provider services. See insurance credentialing.
• Recredentialing cycle: every 36 months.

Prior-auth quirks for behavioral health levels of care

Operational data last reviewed 2026-06-11; quarterly re-verification cadence applies. See also the Optum Behavioral Health page for the carve-out entity’s own operations detail, and /rcm for how automates eligibility, auth tracking, and claim routing for UHC.

• Detox, residential, and PHP require prior authorization on nearly all plans; IOP frequently does as well — authorization goes through Optum, not UHC, even though claims go to UHC.
• Concurrent review cadence: roughly every 5–7 days for residential, 7–14 days for PHP, 2–4 weeks for IOP.
• Criteria: ASAM Criteria for SUD; LOCUS for mental health. Confirm current criteria and any plan-specific clinical guideline references through UHC/Optum before submitting authorization requests.
• Facility claims at these levels of care are billed 837I/UB-04 with the matching revenue codes — mismatched auth level vs. billed level is a top denial driver.

Frequently Asked Questions

UnitedHealthcare credentialing typically takes approximately 60 to 90 days from the time your CAQH ProView application is complete and verified, though timelines can vary. Delays often occur when required documents such as malpractice insurance certificates, state licenses, or DEA registrations are missing or expired. Submit your application well in advance of accepting UHC patients and monitor your CAQH profile for re-attestation deadlines.

UnitedHealthcare generally requires prior authorization for residential treatment, partial hospitalization, and intensive outpatient programs, though specific requirements may vary by plan. Initial authorization requests are typically reviewed against ASAM Criteria for substance use disorders and LOCUS for mental health conditions. You will generally need to provide a clinical assessment, treatment plan, and documentation of medical necessity. Concurrent reviews are typically required approximately every 5 to 7 days for residential care, though intervals can vary.

Yes, out-of-network billing is generally possible for UnitedHealthcare members who have out-of-network benefits. However, reimbursement rates are typically lower and generally based on usual, customary, and reasonable (UCR) rates rather than contracted in-network rates. Members may also face higher deductibles and coinsurance for out-of-network services. Verify out-of-network benefits during VOB before admitting a patient.

Single case agreements (SCAs) may be available when no in-network providers are accessible within a reasonable distance or when specialized services are needed. Contact the UHC provider services line and request to speak with the network management department. You will need to demonstrate that in-network options are insufficient and propose a rate for the specific episode of care. SCAs are negotiated on a case-by-case basis and are not guaranteed.

You can verify benefits through the UHC Provider Portal at uhcprovider.com, by calling the number on the member's insurance card, or through a clearinghouse EDI 270/271 transaction. Key information to verify includes behavioral health coverage, specific level of care benefits, deductible and out-of-pocket status, prior authorization requirements, and any carve-out to Optum Behavioral Health. Always verify benefits within 24 hours of anticipated admission.

UnitedHealthcare's general provider services line is 877-842-3210, published on uhcprovider.com. For behavioral health authorizations and clinical questions, call Optum Behavioral Health at 877-614-0484 or use the number on the member's ID card, since some plans route behavioral health to a dedicated line. Confirm the current number at uhcprovider.com or providerexpress.com before calling, as payer phone numbers change.

The primary UnitedHealthcare electronic payer ID is 87726, which covers most UHC commercial and many affiliated plans. Some UHC-affiliated entities and legacy plans use different payer IDs, so always match the payer ID to the member's plan using your clearinghouse payer list and the member ID card before submitting 837P or 837I claims.

Most UnitedHealthcare commercial plans require claims within approximately 90 days from the date of service or discharge, but the window varies by plan type, state, and contract — some contracts allow 180 days or more, and Medicaid managed care products follow state rules. Check your participation agreement and the UHC administrative guide for the limit that applies to your contract.
