Oregon Medicare Savings Program Authorized Representative

You Cannot Just Log In as Your Parent

If your aging parent needs help applying for Oregon's Medicare Savings Programs, your first instinct might be to sit down at the computer, create a ONE Oregon account using their information, and fill out the application yourself. That approach creates problems.

ODHS requires formal authorization before anyone can sign applications, submit documents, report household changes, or receive copies of decision notices on behalf of another person. Sharing your parent's login credentials or signing their name without authorization can delay processing or create verification issues that stall the entire application.

Form MSC 0231: The Authorization You Need

Oregon's Authorized Representative and Alternate Payee Form — Form MSC 0231 — is the document that gives you legal authority to act on your parent's behalf with ODHS and OHA. It is specific to Oregon's benefit system and operates independently from other legal documents you may already have.

What MSC 0231 authorizes you to do:

• Sign and submit MSP applications through the ONE portal, by mail, or at a local APD/AAA office
• Upload or deliver verification documents (income statements or Medicare card copies)
• Report changes in your parent's household circumstances
• Receive copies of all official decision notices — approvals, denials, requests for information, and renewal packets
• File administrative hearing requests if benefits are denied or reduced

What MSC 0231 does not replace:

• SSA Representative Payee status: a separate designation through Social Security that governs who manages your parent's monthly benefit payments
• Financial Power of Attorney: a legal document governing financial decisions, banking, and property — relevant but separate from ODHS authorization
• HIPAA consent: medical privacy authorizations for healthcare providers and insurers

Even if you already hold durable power of attorney for your parent, ODHS may still require MSC 0231 for their system. Submit both documents together to avoid delays.

How to Complete and Submit the Form

Complete the form according to its signature instructions. If your parent cannot sign, confirm with ODHS how to complete that section before you submit it. The form names you specifically as the authorized representative and describes the scope of authority granted.

You can submit MSC 0231:

• Online: upload it through your parent's ONE Oregon account under supporting documents
• In person: bring it to your local ODHS APD office or Area Agency on Aging
• By mail or fax: send it to the office processing your parent's case

Contact ODHS to confirm that the representative is still listed before relying on an older authorization, and submit an updated MSC 0231 if the representative or granted authority changes.

Applying for Your Parent Step by Step

Once your authorized representative status is established:

1. Gather your parent's documents: Medicare card (red, white, and blue), most recent Social Security benefit statement (showing gross monthly amount before Part B deduction), and any pension or income verification. Oregon has no asset test for QMB, SMB, or SMF, so you do not need bank statements for an MSP-only application.

2. Choose an application channel: The ONE portal at one.oregon.gov is the most common route, but if your parent lives in a rural area with limited internet or the portal is giving errors, you can hand-deliver a paper application to a local APD or AAA office and ask staff to confirm the date it was received. You can also apply by phone at 800-699-9075, though hold times can exceed an hour.

3. Submit the application with MSC 0231 attached: make sure the authorized representative form is part of the same submission so ODHS links it to the case from day one.

4. Monitor the case: as authorized representative, you will receive copies of all notices. Watch for information request notices — these have firm deadlines (typically 10–14 days) and missing one can result in a denial.

Managing Your Parent's Case From Out of State

Many adult children helping parents with Medicare cost relief live outside Oregon. The authorized representative designation works regardless of your physical location. You can:

• Submit and track applications through the ONE portal from anywhere
• Receive electronic copies of notices if you set up digital delivery in the ONE account
• Call the ONE Customer Service Center at 800-699-9075 and identify yourself as the authorized representative to get case updates
• Contact the ADRC of Oregon at 855-673-2372 to locate your parent's local AAA for in-person help you cannot provide remotely

If your parent needs a SHIBA counselor to review their Medicare options, you can schedule the appointment on their behalf and participate by phone.

The Oregon Medicare Savings Programs & Extra Help Guide includes the complete authorized representative setup process, document checklists organized for remote caregivers, and notice-tracking templates so you can manage your parent's case without missing deadlines.
