The main UnitedHealthcare phone number and what it covers

UnitedHealthcare's main customer service line is 1-800-624-8822. This number handles general account questions, billing inquiries, and coverage details for most UnitedHealthcare plans. The line is open Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday 9 a.m. to 5 p.m. Eastern time.

When you call, have your member ID card ready — it's the fastest way to pull up your account. The automated system will ask which type of plan you have (medical, dental, vision, or pharmacy) and route you to the right department. If you're calling about a specific claim or authorization, having your claim number or the date of service also speeds things up.

This main line does not handle Medicare or Medicaid plans, which have separate numbers. If you're unsure which type of plan you have, check your member ID card or the welcome materials you received when you enrolled.

Key Takeaways

  • The general UnitedHealthcare customer service number is 1-800-624-8822, available weekdays 8 a.m. to 8 p.m. Eastern and Saturday 9 a.m. to 5 p.m. Eastern.
  • Medicare and Medicaid plans have separate phone numbers, so confirm your plan type before calling the main line.
  • Having your member ID card and any claim or authorization numbers ready will reduce your wait time.
  • The automated system routes you by plan type, so listen carefully to the menu options that match your coverage.

Phone numbers for Medicare and Medicaid coverage

If you have a UnitedHealthcare Medicare Advantage plan, call 1-800-992-6757. This line is dedicated to Medicare members and handles questions about coverage, claims, and prescription benefits under Medicare plans. Hours are typically Monday through Friday, 8 a.m. to 8 p.m. Eastern, and Saturday 8 a.m. to 5 p.m. Eastern.

For UnitedHealthcare Medicaid plans, the phone number varies by state because each state runs its own Medicaid program. Your member ID card will list the correct number for your state's plan. If you cannot find it on your card, call the main line at 1-800-624-8822 and ask for the Medicaid customer service number in your state.

Both Medicare and Medicaid lines require your member ID to look up your account. If you're calling about a specific service or authorization, have the date and provider name ready as well.

Reaching a nurse line or behavioral health support

UnitedHealthcare offers a nurse information line at 1-800-624-8822 — the same main number, but you'll select the nurse line option from the menu. A registered nurse can answer health questions, help you understand symptoms, and advise whether you need urgent care or can wait for a regular appointment. This service is available 24 hours a day, 7 days a week.

For behavioral health or mental health support, UnitedHealthcare members can also reach the behavioral health line through the main number or by calling the behavioral health provider directly if you already have a therapist or psychiatrist in the network. Your member ID card may list a separate behavioral health phone number depending on your plan.

The nurse line does not replace emergency services — if you are having a medical emergency, call 911 or go to the nearest emergency room instead.

What to do if you cannot reach a representative

If you're on hold for longer than 30 minutes, you can hang up and try calling back at a different time. Early morning (before 9 a.m. Eastern) and mid-afternoon (after 2 p.m. Eastern) typically have shorter wait times than lunch hours or late afternoon.

You can also handle many account tasks online through the UnitedHealthcare website or mobile app without calling. You can check claim status, view your benefits summary, find in-network providers, and request ID card replacements through your online account. This option is often faster than waiting on the phone.

If you have a complex issue that requires a callback, ask the automated system to schedule one. A representative will call you back during business hours rather than keeping you on hold.

Contacting UnitedHealthcare about a specific claim or authorization

If you're calling about a claim that was denied or a prior authorization request, have the claim number or authorization request number ready. You can find these on your explanation of benefits (EOB) statement, which UnitedHealthcare sends by mail or makes available in your online account.

When you reach a representative, explain whether you're calling about a claim decision you disagree with or an authorization that hasn't been processed yet. These are handled by different departments, and the representative will route you correctly. If you're disputing a claim decision, ask about the appeal process — you have a set time window to request an appeal, and the representative can explain your options.

For authorization requests that are still pending, the representative can check the status and tell you when to expect a decision. Some authorizations are approved within 24 hours; others take up to 5 business days depending on the type of service.

Using the UnitedHealthcare website instead of calling

The UnitedHealthcare website (www.uhc.com) lets you handle many tasks without calling. You can log into your account to view your benefits, check claim status, find in-network doctors and hospitals, and request a replacement ID card. The website also has a chat feature during business hours if you prefer typing to calling.

If you don't have an online account yet, you can create one using your member ID and date of birth. Once you're logged in, you can set up email notifications for claim updates, so you'll know the status without having to call or check the website repeatedly.

The website is available 24 hours a day, so you can look up information at any time, even outside customer service hours.
