Available to both providers and third-party billing companies, digital TIN registration takes about 10 minutes to complete.
If your TIN has been registered successfully, you may start filing claims for reimbursement to avoid delays with processing and payments. You can gain access to the UnitedHealthcare Provider Portal's helpful self-service tools, up-to-date information and news to support every stage of care delivery.
If you need to submit an out-of-network claim, or you have received a letter requesting information to verify provider billing, you can start the process of registering your TIN now. Be sure to have a PDF version of your W-9 tax form, and documentation to prove your primary practice location address.
To check the status of a TIN you have already registered, you can view your application any time.
