How do I register for the Imperial Health Plan Provider Portal?
⌄
To register, visit
www.imperialhealthplan.com,
“Providers”, “Provider Portal Web Application”.
You will be asked to enter your Tax ID, NPI, user information, address, etc. You must also submit your W9 to
Portal@imperialhealthholdings.com.
Once submitted, you will receive a confirmation email with instructions to complete your account setup.
I manage multiple practices or practice under multiple Tax IDs. Do I need to register more than once?
⌄
No. If you work under multiple Tax Identification Numbers (TINs), you must provide each TIN at time of registration by submitting an Excel file with all Tax ID numbers and corresponding W9 to
Portal@imperialhealthholdings.com.
This ensures that your access and visibility in the portal correctly match the providers and members associated with each tax ID.
I completed the registration but didn’t receive the confirmation email. What should I do?
⌄
First, check your spam/junk folder and verify that your inbox is not blocking automated emails.
If you still cannot locate the message, please contact our Provider Portal team for assistance at
Portal@imperialhealthholdings.com.
What information do I need to complete portal registration?
⌄
You will need:
• Your Tax Identification Number(s) (TIN) (remember to provide all associated TINs)
• Your National Provider Identifier (NPI)
• W9(s)
• Your practice or facility name
• A valid email address for registration confirmation
• The name of the person who will serve as the primary contact for the portal
Who should complete the Provider Portal registration?
⌄
Each practice should determine whether the office manager, billing coordinator, or designated administrative contact should register.
Can multiple staff members have access to the Provider Portal?
⌄
Yes.
Each user will need to register separately and receive their own login credentials.
I already have a portal login but need access to an additional tax ID. What should I do?
⌄
No, you do not need to submit another application or registration. You will need to submit all W9s that are associated with your organization, so that we can verify your association with these other TINs and link them to your current account.
How long does it take for my registration to be approved?
⌄
Portal registrations are typically processed within 3–5 business days.
If additional validation is required, it may take slightly longer. The Portal team will notify you if further documentation is needed.
Where can I find updated step-by-step instructions?
⌄
Updated written instructions are posted on the Provider Portal registration page as well as a step-by-step provider portal “how-to” video.
