Filing Claims for Original Medicare Parts A and B
When you receive care under Original Medicare and do not use a participating provider or direct billing, you may need to file a paper claim. The standard UnitedHealthcare Medicare claims address for Original Medicare is PO Box 25128, Omaha, NE 68125-0128.
Include itemized statements from providers, receipts, and any Explanation of Benefits summaries from other insurers. Claims submitted by mail typically take 30–45 days to process, though this can vary during peak periods or when documentation requires clarification.
Keeping digital copies and a log of submission dates helps you track the status and resolve any missing documentation requests quickly.
Submitting Claims Through Medicare Advantage Plans
Most Medicare Advantage members coordinate claims through their plan network, so direct claims to the UnitedHealthcare Medicare claims address are rarely necessary. If you need to submit an out-of-network claim or a non-covered service, use the plan-specific address listed on your member ID card or the plan website.
Many plans offer online tools and mobile apps that allow you to upload claims and receipts in real time, which can shorten processing time compared to mail submissions. Always check your plan’s guidelines before sending any documentation to ensure it matches the format and content requirements.
The table above shows that Medicare Advantage claims routed through the standardized Omaha address often follow faster timelines, particularly when submitted electronically or through in-network providers.
Handling Medicare Part D and Pharmacy Claims
For Medicare Part D prescriptions, UnitedHealthcare typically coordinates directly with pharmacies, so members seldom need to submit manual claims. If a claim is denied or a reimbursement is delayed, you may send documentation to the address listed for Medicare Part D in the summary table, usually PO Box 620777, Omaha, NE 68162-0777.
Include the pharmacy claim number, date of service, and a copy of the denial notice from your plan. Providing clear explanations for why a claim should be reconsidered increases the likelihood of a favorable redetermination.
Timely follow-up within 10–15 business days can prevent prolonged gaps in coverage and help you maintain consistent access to medications.
Appealing Decisions and Formal Grievances
If your claim or coverage determination is not resolved to your satisfaction, you have the right to file an appeal. The UnitedHealthcare Medicare claims address for appeals and formal grievances is PO Box 620812, Omaha, NE 68162-0812.
Your appeal should include the original determination letter, a Statement of Appeal with dates and service details, and any supporting clinical or documentation evidence. Adhering to stated deadlines, often 60 days from the decision date, helps preserve your procedural rights.
Tracking each submission via certified mail or secure upload features provides a clear record and can be valuable if further escalation within Medicare or to external agencies becomes necessary.
