Hey there! If you’ve ever struggled with figuring out how to pay your medical bills from Southwest Medical Associates (SMA), you’re definitely not alone. I recently had to help my mom figure out their new payment system, and wow, it was quite the adventure! Today, I’m sharing everything I learned about SMA’s bill pay options to save you the headache I went through.
The Big Change: SMA Switched to MyChart in December 2024
First things first – Southwest Medical Associates made a major change to their patient portal in December 2024 They moved from their old system to MyChart, which affects how you access your medical records AND how you pay your bills.
This change caught a lot of patients off guard (including us!), so if you’re feeling confused about where to go or how to login, you’re not alone.
Your Southwest Medical Bill Pay Options
Let’s break down all the ways you can pay your SMA bill
1. MyChart Patient Portal (For Bills After December 1, 2024)
This is now the primary way to handle your Southwest Medical bill payments for any services you received on or after December 1, 2024.
How to access it:
- Visit the Southwest Medical patient online services page
- Look for the “MyChart Patient Portal” section
- Click “Sign in or register online”
- If you’re a new user, you’ll need to register first
What you can do in MyChart:
- View and pay your medical bills
- Send messages to your doctor
- Schedule appointments (including virtual visits)
- View your medical records
- Renew prescriptions
I found the MyChart interface pretty straightforward, but it did take me a few minutes to get used to the new layout compared to the old system.
2. FollowMyHealth (For Bills Before December 1, 2024)
If you need to access your billing history or pay for services that occurred before December 1, 2024, you’ll need to use the old system.
How to access it:
- Go to the SMA patient online services page
- Look for “View medical records from before December 1, 2024”
- Click “Visit FollowMyHealth”
- Sign in with your existing credentials
It’s kinda annoying to have to use two different systems depending on when you received care, but that’s just how it is during this transition period.

-

Pro tip: I always take a screenshot of my payment confirmation just in case there’s ever a question about whether I paid!
Common Issues with SMA Bill Pay (And How to Fix Them)
During my adventure with SMA’s bill pay system, I ran into a few hiccups. Here are some common problems and solutions:
Error Messages During Login
If you’re getting error messages when trying to login to MyChart, try these fixes:
- Clear your browser cache and cookies
- Try a different browser (Chrome or Firefox usually work best)
- Use incognito/private browsing mode
- Double-check that you’re using the correct username/password
- If using the app, try the website instead (or vice versa)
Can’t Find Your Bill
If you can’t locate your bill in the system:
- Check if you’re looking in the right portal (MyChart vs. FollowMyHealth)
- Verify the date of service to determine which system to use
- Call the billing department if your bill should be available but isn’t showing up
Payment Processing Issues
Sometimes the payment system gets temperamental:
- Try a different payment method if available
- Ensure your card isn’t expired or near its limit
- Check that your billing address matches what’s on file with your card issuer
- If online payment fails repeatedly, you might need to call or try another payment method
Alternative Ways to Pay Your Southwest Medical Bill
Not everyone is comfortable paying bills online, and sometimes technical issues make it necessary to use alternative methods. Here are other ways to pay your SMA bill:
By Phone
Call the Southwest Medical billing department directly. Have your account number and payment information ready.
By Mail
You can mail a check or money order to:
Southwest Medical AssociatesP.O. Box XXXXXLas Vegas, NV XXXXX
(Check your bill statement for the exact mailing address)
In Person
If you prefer to pay in person, you can visit any Southwest Medical billing office during regular business hours. Bring your statement and be prepared to show ID.
Understanding Your SMA Bill
Medical bills can be confusing, and Southwest Medical’s are no exception. Here’s a quick guide to understanding what you’re looking at:
- Statement Date: When the bill was generated
- Account Number: Your unique identifier (needed for all billing inquiries)
- Service Date: When you received medical care
- Description: Brief explanation of the service provided
- Charges: The original cost before insurance
- Adjustments: Discounts or reductions (often from insurance)
- Insurance Paid: What portion your insurance covered
- Patient Responsibility: The amount you owe (this is what you need to pay)
I always double-check my bill against my insurance explanation of benefits (EOB). Sometimes there are discrepancies, and it’s better to catch them early!
Tips for Managing Your Southwest Medical Bills
Based on my experience with SMA’s billing system, here are some tips that might help you:
- Set up automatic payments in MyChart if you have recurring bills
- Keep track of all confirmation numbers when making payments
- Check your email regularly for billing notifications
- Update your insurance information promptly if it changes
- Save digital copies of your paid bills
- Consider setting calendar reminders for payment due dates
I’ve found that staying organized with medical bills saves a ton of headache down the road!
What to Do If You’re Having Trouble with Transferable Credits
One issue that’s been reported by patients is difficulty with transferring credits between accounts. If you’re experiencing an error (like error code 401120800) when trying to transfer credits, here are some steps to try:
- Try different browsers – Some users reported success switching from their desktop to mobile or using incognito mode
- Verify account details carefully – Make sure names are spelled exactly as they appear in the system
- Contact customer service – If online attempts fail, calling Southwest Medical directly is usually the most effective solution
According to discussions online, this appears to be a known IT issue affecting multiple users. Some patients have reported that the problem resolved itself after a few days, while others needed to call to have the transfer processed manually.
