iRhythm sends bills after your heart monitor test, and you can pay online, by phone, or by mail
After iRhythm Technologies completes your cardiac monitoring test — whether it's a Zio patch or other wearable device — you'll receive a bill from them or from the healthcare facility that ordered the test. iRhythm accepts payment through their patient portal (the easiest route), by phone with a representative, or by mailing a check. The bill will show what your insurance covered and what you owe out of pocket.
The amount you owe depends on your insurance coverage, your deductible status, and whether iRhythm is in-network for your plan. If you haven't met your deductible yet, you may owe the full test cost. If you're uninsured or underinsured, iRhythm may offer a cash discount or a payment plan — it's worth asking before you pay in full.
Key Takeaways
- You can pay iRhythm bills online through their patient portal, by calling their billing department, or by mailing a check to the address on your bill.
- Your out-of-pocket cost depends on your insurance plan, deductible, and whether iRhythm is in-network — check your explanation of benefits (EOB) to see what your insurer paid.
- If you can't pay the full amount at once, ask iRhythm's billing team about payment plans or discounts for uninsured patients before the bill becomes past due.
- Late payments may be reported to credit bureaus and can result in collection calls, so contact iRhythm's billing department if you're having trouble paying.
Paying online through the iRhythm patient portal
The fastest way to pay is through iRhythm's online patient portal. Log in with the username and password you created when you registered for your test, or create an account if you haven't already. Once logged in, look for a "Billing" or "Pay My Bill" section — this will show your current balance and any invoices.
Click on the bill you want to pay and select your payment method: debit card, credit card, or bank account (ACH transfer). Enter your payment information and the amount you're paying. iRhythm will send you a confirmation email with a receipt. Payments made online typically post to your account within one to two business days.
If you don't remember your login information, use the "Forgot Password" link on the portal homepage. If you can't find the billing section or your bill doesn't appear, contact iRhythm's patient billing team by phone — their number should be on your bill or in any email notifications you received.
Paying by phone with iRhythm billing
You can call iRhythm's billing department to pay over the phone. The phone number is printed on your bill statement. Have your bill handy when you call, along with your debit card, credit card, or bank account information if you want to pay by card or ACH transfer.
A representative will confirm your identity, pull up your account, and walk you through the payment process. They can also answer questions about what you owe, why a charge appears on your bill, or whether you're responsible for the full amount. If you're having financial hardship, this is also the time to ask about payment plans or financial assistance programs — some representatives have authority to set up arrangements on the spot.
Call during business hours listed on your bill. If you reach an automated system, select the option for billing or payments, and you'll be routed to the right department.
Mailing a check or money order
If you prefer not to pay online or by phone, you can mail a check or money order to the address shown on your bill. Write your account number or patient ID on the check so the payment gets matched to your account correctly. Mail it to the billing address listed on your statement — do not send it to iRhythm's main office address, as it may be delayed.
Mailed payments typically take five to ten business days to arrive and post to your account, depending on mail delivery and iRhythm's processing time. If you need the payment to arrive by a certain date, consider paying online or by phone instead. Keep a copy of your check or money order number for your records.
Understanding your bill and what you owe
Your iRhythm bill will list the test performed, the date of service, the total charge, what your insurance paid, and your out-of-pocket responsibility. If you have insurance, you should also receive an explanation of benefits (EOB) from your insurer showing what they covered and why.
Compare your iRhythm bill to your EOB. If the amounts don't match — for example, if iRhythm is billing you for something your insurance says they covered — contact iRhythm's billing department with your EOB in hand. Billing errors do happen, and they can often be corrected quickly if you catch them early.
If you're uninsured, the bill will show the full charge. Ask iRhythm whether they offer a cash discount (some do, typically 10 to 20 percent) or whether they can reduce the bill based on your income. These discounts are not automatic, but billing representatives can discuss options with you.
Payment plans and financial hardship options
If you can't pay the full bill at once, contact iRhythm's billing department before the bill becomes overdue. Many healthcare providers, including iRhythm, offer payment plans that let you spread the cost over several months with no interest. Some also have financial assistance programs for patients with low income or significant medical debt.
When you call, be honest about what you can afford to pay each month. The representative may be able to set up a plan on the phone. Get the terms in writing — the monthly amount, the number of payments, and the due date. Make your payments on time to avoid late fees or collection action.
If iRhythm doesn't offer a plan that works for your budget, ask whether they accept third-party payment plans like CareCredit or Affirm. These are credit products that let you finance medical bills, though they charge interest if you don't pay off the balance within the promotional period.
What happens if you don't pay
If your bill goes unpaid, iRhythm will send you reminder notices by mail or email. After 30 to 60 days, they may report the debt to the three major credit bureaus (Equifax, Experian, and TransUnion), which will lower your credit score. After 90 to 120 days, they may send your account to a collection agency, and you'll start receiving calls from collectors.
A medical debt in collections can stay on your credit report for up to seven years and will make it harder to get loans, credit cards, or favorable interest rates. If you're struggling to pay, it's better to contact iRhythm now and set up a plan than to wait for collection calls.
If you believe the bill is wrong or you were billed in error, you have the right to dispute it. Send a written dispute to the address on your bill, explaining what you think is incorrect. iRhythm must investigate your dispute within 30 days. A dispute does not stop collection action, but it does create a record that you contested the bill.
Frequently Asked Questions
Can I pay my iRhythm bill with insurance?
No — you pay iRhythm directly. Your insurance company pays iRhythm separately for their portion of the test. You are responsible for your out-of-pocket cost, which is the amount your insurance didn't cover. Check your explanation of benefits to see what your insurer paid and what you owe.
What if I don't have an account on the iRhythm patient portal?
You can create one using your email address and the information from your bill or test paperwork. If you can't remember your patient ID or account number, call iRhythm's billing department — they can look you up by name and date of birth and help you set up portal access.
Does iRhythm charge a fee for paying by credit card?
iRhythm does not charge a processing fee for credit card payments made through their portal or by phone. However, if you use a third-party payment service or app, that service may charge a fee. Pay directly through iRhythm to avoid extra charges.
Can I negotiate my iRhythm bill if I'm uninsured?
Yes. Call iRhythm's billing department and ask about cash discounts or financial assistance based on your income. They are not required to offer either, but many do. It never hurts to ask before you pay the full amount.
What should I do if I received a bill from a collection agency instead of iRhythm?
Contact the collection agency and ask for the original creditor's name and the amount owed. You can also request a debt validation letter, which the agency must send within 30 days. If the debt is yours, you can still negotiate a payment plan or settlement with the collector. If you believe it's a mistake, send a written dispute within 30 days of receiving the notice.
