UnitedHealthcare Phone Numbers

Call the phone number on your plan ID card for questions and information related to your UnitedHealthcare Medicare Advantage (Medicare Part C) or Medicare Part D plan. 

Your plan ID card may display a customer service phone number along with a phone number for a nurse line if such a benefit is included with your plan.  

Members of these plans will also typically have an online portal where you can log in to perform certain tasks and find information related to your plan. The website for this online portal should be displayed on your ID card as well. 

If you’re having technical difficulties with the phone number listed on your ID card, you may call 1-800-721-0627.
