How to Pay Your Bill

Pay Without Login (Guest Pay)

https://pay.instamed.com Payments

Have a healthcare bill? Pay online with the InstaMed Patient Portal, a simple and secure way to pay any healthcare provider. Pay all of your medical bills …

RAYUS supports true guest pay through InstaMed, so you can make a one‑time payment without creating a full account.

You need:

  • The first 4 digits of your RAYUS account number, from the top of your bill.

Steps:

  1. Go to the official RAYUS “Pay My Bill” page:
    • https://rayusradiology.com/pay-my-bill/
  2. On that page, find the section “Pay Your Bill Online” / “Pay Online as a Guest”.
  3. Enter the first 4 digits of your account number (from the top of your statement) and click “Pay Now”.
  4. You will be redirected to RAYUS’s payment facilitator, InstaMed.
  5. On the InstaMed screen, choose the guest one‑time payment option by clicking the “Pay Here” link under the Pay Now button.
  6. Enter the rest of your account information and payment amount as requested.
  7. Pay with an accepted method (InstaMed typically supports credit/debit cards and bank account (ACH); exact options appear on the screen).
  8. Submit and save your confirmation.

This guest option works for most RAYUS‑affiliated centers; if your bill says otherwise, follow the specific instructions on your statement.

Pay Online (With Account)

If you want to view statements, enroll in paperless billing, and reuse stored payment methods, you can log into or create an InstaMed account.

Steps:

  1. Go to https://rayusradiology.com/pay-my-bill/.
  2. Enter the first 4 digits of your account number and click “Pay Now”.
  3. When redirected to InstaMed, choose to log in or create a login instead of using guest pay.
  4. For new users:
    • Register with your emailpassword, and verification steps required by InstaMed.
    • Link your RAYUS account by providing your account number and other identifiers from your bill.
  5. Once logged in, you can:
    • View statements online,
    • Enroll in paperless billing, and
    • Make one‑time or recurring payments.
  6. Use the InstaMed account to pay with stored card or bank details for faster checkout.

Note: If you were seen in certain communities (Bridgeton MO – SSM Health Imaging; Milwaukee WI; Duluth MN; St. Louis MO; Valparaiso IN), RAYUS says you must visit those centers’ own pages for bill‑pay details instead of the standard InstaMed flow.

Pay by Phone

RAYUS allows phone payments through their Billing Customer Service Department, but the phone number and hours vary and are printed on your specific bill.

From their instructions:

  • “To pay your bill by phone, call our Billing Customer Service Department at the phone number and during the business hours displayed on your bill.”

Because the exact billing phone number is statement‑specific, do not guess or use generic contact numbers.

Steps:

  1. Look at your RAYUS statement for the Billing Customer Service number and hours.
  2. Call that number during the listed hours.
  3. Have your account numberdate of birth, and statement amount ready.
  4. Ask to make a payment by phone and confirm:
    • Accepted payment methods (usually credit/debit card, sometimes ACH), and
    • Whether there is any phone payment fee.
  5. Provide your payment info, confirm the amount and date, and request a confirmation number.

If you don’t have your bill handy but need billing help (not necessarily to pay), you can call RAYUS’s RCM Customer Service line associated with their financial assistance program:

  • RCM Customer Service: 866‑225‑6265 (Mon–Fri, 8:00 a.m.–6:00 p.m. CST)

This line is for broader billing support and financial assistance applications; they can direct you to the correct payment path as well.

Pay In Person

RAYUS centers are outpatient imaging facilities; they typically accept payment at the time of service at the local imaging center front desk.

For post‑visit bills:

  • The main Pay‑My‑Bill page only lists online, mail, and phone as standard options.

If you want to pay in person:

  1. Use the Contact Us or Locations page to find your local RAYUS center’s phone number.
  2. Call and ask if they can accept payment in person for an existing bill.
  3. If they say yes, bring:
    • Your statement, and
    • Your payment method (card, check, etc.), per that center’s policy.
  4. Request a receipt showing that your payment was applied to your account.

Because policies can differ by market or partner facility (e.g., hospital‑based centers), always verify with your specific location before assuming in‑person payment is available.

Pay In Store (Retail Locations)

RAYUS does not indicate any partnership with retail bill‑pay locations like Walmart, CVS, or grocery chains.

Third‑party bill‑pay sites like doxo list RAYUS Radiology as a biller and allow payment by bank account or card. However:

  • doxo is a third‑party service,
  • It may charge extra service fees, and
  • Payments can take extra days to reach RAYUS.

For urgent or time‑sensitive bills, use:

  • The official InstaMed portal via RAYUS,
  • The billing phone number on your statement, or
  • Mail directly to the address on your RAYUS bill.

Pay by Mail

RAYUS’s Pay My Bill page confirms that you can pay by mail using the statement coupon.

Steps:

  1. Find the payment coupon on your RAYUS bill (the detachable portion).
  2. Write a check (or money order, if preferred) for the amount due, payable to the entity listed on the bill (e.g., “RAYUS Radiology” or a partner name—use exactly what’s printed).
  3. Write your account number on the memo line.
  4. Place the check and the statement coupon in the return envelope, if provided, or in your own envelope addressed to the remittance address printed on your bill.
  5. Mail early enough that your payment arrives before the due date, not just postmarked.

Because RAYUS services many regions and partners, they do not publish a single universal PO box for all mail payments; always rely on the remit‑to address on your specific statement.

Common Issues and Fixes

Cannot Log In

Issues here usually involve InstaMed login, not a separate RAYUS account.

Solutions:

  • If you only need to pay once, skip login and use guest pay by entering the first 4 digits of your account number and then choosing the “Pay Here” guest option.
  • If you created an InstaMed account and can’t log in, use InstaMed’s forgot password or help links on the login page.
  • If InstaMed says it can’t find your account, verify that your account number and any other identifiers match exactly what is on your RAYUS bill.
  • For persistent issues, call the Billing Customer Service number on your bill or RCM Customer Service at 866‑225‑6265 for help applying a payment.

Forgot Account Number

If you lost or don’t have your bill:

  • Check your email and mail for a recent RAYUS statement; the account number is at the top.
  • If you have portal access (myExamAnswers or a local portal), you may see your account number in visit/billing details.
  • If still stuck, call your local imaging center (via the Locations/Contact Us page) or RCM Customer Service at 866‑225‑6265, and verify your identity so they can look up your account.

Payment Not Going Through

If an online payment fails:

  • Confirm your card or bank info, including billing ZIP.
  • Try a different browser/device or check your internet connection.
  • Ensure you are on the correct payment link (InstaMed via rayusradiology.com, not a random payment page).
  • If your bank shows a pending charge but InstaMed/RAYUS shows unpaid, contact Billing Customer Service with your confirmation ID and bank proof before paying again.

If phone or mail payment issues arise:

  • Keep copies of check imagesmoney‑order receipts, and phone confirmation numbers, then call the billing number on your statement or 866‑225‑6265 to investigate.

Website Not Working

If rayusradiology.com or InstaMed isn’t loading:

  • Confirm the URLs:
    • RAYUS bill pay page: https://rayusradiology.com/pay-my-bill/
    • InstaMed payment form: the link you are redirected to (e.g., https://pay.instamed.com/Form/Payments/New?id=cdi_epic).
  • Try again later or from another device/network.
  • If your due date is close, call the Billing Customer Service phone number on your bill or 866‑225‑6265 to pay by phone or get alternate guidance.

Tips to Reduce or Manage Your Bill

Payment Plans

RAYUS mentions working with patients on financial assistance and discounts in some regions (e.g., Alomere Health partnership).

Options:

  • Contact Customer Service at 866‑225‑6265 to ask whether they can:
    • Set up a payment plan, or
    • Connect you to a financial assistance program for your region.
  • For RAYUS a service of Alomere Health, they specifically offer a financial assistance program based on family size and income (100%–244% of Federal Poverty Guidelines).

Negotiation Tips

While you can’t usually negotiate list prices on imaging after the fact, you can:

  • Request an itemized bill and compare it against your insurance Explanation of Benefits (EOB) to confirm correct coding and allowed amounts.
  • If the insurer shows a different patient responsibility than your RAYUS bill, call both your insurer and RAYUS billing to resolve discrepancies.
  • Ask whether any prompt‑pay discounts or self‑pay discounts apply if you are uninsured or paying out‑of‑pocket.

Avoiding Late Fees

  • Pay as soon as you receive your bill, especially if you are uninsured; they note that payments are due upon receipt unless other arrangements have been made.
  • Use online guest pay for the fastest posting, especially close to the due date.
  • If you’re waiting on insurance appeal results, call Customer Service to let them know and ask how to avoid collections while the claim is under review.

Assistance Programs

RAYUS (Alomere Health) describes a financial assistance program:

  • For uninsured or under‑insured patients with household income between 100% and 244% of Federal Poverty Guidelines, discounts may be available.
  • To apply, you must:
    • Complete and sign the financial assistance application,
    • Provide supporting income documents, and
    • Submit via email to [email protected] or mail to: Attention: RCM Customer Service
      RAYUS Radiology
      5775 Wayzata Blvd., Suite 400
      St. Louis Park, MN 55416
  • For help completing the application, call 866‑225‑6265 or local assistance partners like 320‑304‑3458 (for certain regions, per the Alomere program).

Check your specific RAYUS region for local variants or additional assistance partnerships.
