UnitedHealth Group
UnitedHealth Group Incorporated is one of the largest healthcare and health-benefits companies in the United States. The organization operates primarily through two major businesses, UnitedHealthcare and Optum. UnitedHealthcare provides employer-sponsored, individual, Medicare, Medicaid, community, global, and specialty health-benefit products, while Optum provides healthcare delivery, pharmacy services, analytics, technology, payment solutions, and other health-services capabilities. UnitedHealth Group is publicly traded on the New York Stock Exchange under the ticker UNH.
The company has grown into an unusually large healthcare enterprise. For full-year 2025, UnitedHealth Group reported $447.6 billion in consolidated revenue. UnitedHealthcare served approximately 49.8 million people during 2025, while Optum supported more than 123 million consumers across its businesses. As of December 31, 2025, UnitedHealth Group employed more than 390,000 people, including nearly 165,000 clinical professionals.
A major recent corporate change concerns leadership and executive-office structure. Stephen J. Hemsley is the current Chief Executive Officer and Chairman. UnitedHealth Group’s 2026 SEC filings list 1 Health Drive, Eden Prairie, Minnesota 55344, together with 655 New York Avenue NW, Washington, DC 20001, as principal executive offices. This is important because older headquarters references may identify only the Minnesota location.

UnitedHealth Group publishes this as its main corporate contact and Investor Relations phone number.
UnitedHealth Group itself does not operate one universal consumer Customer Service number because member service is handled through UnitedHealthcare, Optum, and individual benefit plans. UnitedHealthcare members should use the number on their insurance ID card or their plan-specific support channel.

UnitedHealth Group also uses Broadridge for transfer-agent and shareholder-record services.
For a corporate or investor-level inquiry, 800-328-5979 is the clearest verified company-level contact. For health-plan questions, however, calling the corporate office is usually not the fastest route. UnitedHealthcare members should use the Member Services phone number printed on their insurance ID card because that number is tied to the member’s specific employer, Medicare, Medicaid, or individual plan.
Before calling, have the member ID, group number, date of birth, claim or authorization number, provider name, and dates of service ready where relevant. For Optum services, use the support information associated with the specific Optum product, pharmacy account, clinic, HSA, or provider service. This avoids unnecessary transfers between UnitedHealth Group’s many distinct operating businesses.
For investor or shareholder matters, contact Investor Relations directly at 800-328-5979 or Investor_Relations@uhc.com. Employment applicants should use the UnitedHealth Group careers portal, while technical assistance with an application is available at 866-566-8715.

Complaints can involve denied health-plan benefits, claim processing, prior authorization, provider-network access, pharmacy coverage, billing, Optum services, customer-service conduct, privacy, or other healthcare administration matters. Before escalating, gather the member ID card, claim or reference numbers, explanation-of-benefits documents, provider information, medical or pharmacy documentation where applicable, dates of previous calls, and copies of written correspondence.
Begin with the Member Services number on your UnitedHealthcare insurance card or the support number attached to the relevant Optum product. Explain the issue clearly, provide the claim or service date, and ask the representative to document the complaint. Request a call reference number or case number and record the representative’s name and the date of the conversation.
If the matter involves claims, prior authorization, pharmacy benefits, Optum Rx, HSA administration, provider access, or another specialized service, request transfer to the department responsible for that issue. Keep all letters, denial notices, explanation-of-benefits statements, and provider documentation because these materials may be needed for a formal appeal.
If the first-level representative cannot resolve the complaint, ask for a supervisor or escalation specialist. Explain the steps already taken, identify the unresolved point, and request a specific outcome. Keep a record of every case number, promised callback, and deadline.
For health-benefit disputes, follow the grievance or appeal instructions in the plan documents, denial letter, or member portal. UnitedHealthcare plans have formal grievance and appeals procedures that vary by product and state. Written complaints are especially important when a deadline applies to a coverage or claim appeal.
For a serious unresolved corporate matter, correspondence can be sent to UnitedHealth Group Incorporated, 1 Health Drive, Eden Prairie, MN 55344. Corporate headquarters should not replace a plan-level appeal, but it can be used when repeated support attempts have failed or the complaint concerns enterprise-level conduct.
Use the formal UnitedHealthcare appeals, grievance, pharmacy appeal, provider dispute, privacy, or Optum complaint process that corresponds to the service involved. A benefit denial should generally be challenged through the official appeal route rather than only through general Customer Service.
The appropriate regulator depends on the complaint. State insurance departments regulate many fully insured health plans, while Medicare complaints may involve the Centers for Medicare & Medicaid Services. Medicaid issues can involve the state Medicaid agency, and certain employer self-funded plans may fall under the U.S. Department of Labor’s Employee Benefits Security Administration.
Billing or payment disputes may also involve an employer benefits administrator, healthcare provider, pharmacy, HSA administrator, card issuer, or appropriate state consumer-protection agency. If the issue concerns unauthorized charges or financial transactions, preserve bank records and dispute the transaction through the proper financial channel.
If administrative appeals and regulatory processes do not resolve a serious dispute, review the applicable plan documents and legal terms to determine whether litigation, arbitration, an external medical review, or another formal process is available. Healthcare disputes often have strict filing deadlines, so keep complete records and obtain qualified professional advice where necessary.
