Once insurance pays, a patient balance is often what is left. It may be a deductible, a copay, or coinsurance, and it usually makes up a growing share of what a practice collects. These accounts are slower and smaller than insurance claims, so they get less attention, even though a missed statement or a late follow-up can leave money uncollected for months.
This post lays out a workflow that starts at the visit and ends in payment, with notes on timing, statements, and collections.
What Does “Balance Billing” Mean?
In healthcare, balance billing has a narrow meaning. It refers to a provider billing a patient for the difference between the provider’s charge and what the insurer allowed, usually after an out-of-network visit. The No Surprises Act prohibits it in several situations, including emergency services and certain non-emergency services from out-of-network providers at in-network facilities, and some states add their own limits.
Many billing teams use the phrase more loosely to mean billing the patient for the remaining responsibility after insurance. That is the subject of this post. A contracted provider can bill only the patient responsibility shown on the remittance, such as deductible, copay, and coinsurance. The difference between the charge and the contracted rate is a contractual adjustment and cannot be billed to the patient.
Step 1: Verify Coverage and Collect at the Visit
The cheapest balance to collect is the one paid at check-in. Verify eligibility and benefits before the appointment so staff know the copay, the deductible remaining, and the coinsurance. Our overview of insurance eligibility verification covers what to check.
Collect the copay at the visit. For services with a known cost, such as a procedure, give the patient an estimate and ask for the expected deductible portion when you can. Treat the estimate as an estimate, because the final amount depends on how the payer processes the claim.
Step 2: Post the Insurance Payment and Confirm Patient Responsibility
Do not send a statement until the insurance claim has been adjudicated. A statement sent early can show a wrong balance, and it creates calls from confused patients.
When the remittance arrives, post the payment and check how the patient responsibility is coded. Amounts the patient owes appear with the group code PR, along with reason codes such as 1 (deductible), 2 (coinsurance), and 3 (copay). Contractual adjustments appear under a different group code and should never move to the patient balance.
Step 3: Check the Balance Before You Bill It
A few checks prevent most statement disputes:
- Does the allowed amount match your contract rate? If it looks low, the patient’s share may also be wrong.
- Is there a secondary insurance that should be billed first?
- Did the payer deny the claim for something fixable, such as a coding error or missing authorization? A denial caused by the practice is generally not the patient’s responsibility.
- Was the copay already collected?
Our guide to claim status codes can help you read the payer’s response if the status is unclear.
Step 4: Send a Clear First Statement
Send the first statement promptly after the insurance payment posts. A statement that is easy to read gets paid sooner. It should show the date of service, the service, the amount billed, insurance payments, adjustments, the patient balance, a due date, accepted payment methods, and a phone number for questions.
Offer more than one way to pay: online, by phone, by mail, and in person. Many practices see better results when the statement links directly to a payment portal. Plain language helps too. “Your insurance paid $140 and applied $60 to your deductible” is clearer than a string of codes.
Step 5: Offer Payment Plans and Financial Assistance
Not every patient can pay in one payment. A written payment plan policy lets staff offer terms consistently, for example, a set number of monthly payments for balances above a certain amount. Many practices also have a hardship or financial assistance policy. Writing these down protects the practice and the patient, and it makes follow-up conversations shorter.
Step 6: Follow Up on a Set Schedule
A fixed cadence keeps accounts from sitting. The timing below is only an example, and you should adjust it to your own policy, payer contracts, and state law:
- Day 0: first statement after insurance posts
- Day 30: second statement with a reminder
- Day 45–60: phone call or text and another statement
- Day 75–90: final notice stating the next step if unpaid
Document every contact with the date, method, and result. Those notes matter if the patient disputes the balance or the account moves to collections.
Step 7: Decide on Collections
When internal follow-up fails, practices usually send the account to a collection agency or write it off as bad debt, according to their policy. Before sending accounts out, confirm the balance is accurate, the patient has received notice, and no appeal, dispute, or insurance reprocessing is pending.
Collection rules vary. Third-party collection agencies are covered by the federal Fair Debt Collection Practices Act and state laws, and some states add rules for providers collecting their own debts. Credit reporting rules have also been changing. The federal CFPB medical debt rule was vacated by a court in 2025, but the three major credit bureaus have said they continue to follow voluntary policies, such as not reporting medical collections under $500 and waiting a year before reporting unpaid ones. A number of states have their own restrictions. Check current rules with your attorney or collection partner before relying on any of this.
Step 8: Track a Few Numbers
Review patient AR separately from insurance AR. A short monthly report covers most needs: total patient balances, the share over 90 days, collection rate on patient balances, and point-of-service collections. Your AR aging report can be filtered by responsible party to show this.
When to Get Outside Help
Patient billing takes steady follow-up, and it competes with claims work for staff time. Rapid RCM Solutions offers AR and denial management for practices that need patient follow-up, statements, and aging balances handled on a regular schedule.
Conclusion
A patient billing workflow works when the balance is accurate, the statement is clear, and follow-up happens on a schedule. Collect what you can at the visit, wait for insurance to finish, check the balance, and track patient AR separately so it does not get lost among claims.
FAQs Patient Balance Billing Workflow
What is balance billing in medical billing?
It usually means billing a patient for the difference between the provider’s charge and the amount the insurer allowed. It is restricted in many situations, including under the No Surprises Act.
When should I send a patient statement?
After the insurance claim has been adjudicated and the payment has posted. Sending one earlier often shows an incorrect balance.
Can I bill the patient for a claim the payer denied?
It depends on the reason. If the denial was caused by a practice error, the patient generally should not be billed. Check your payer contract and state rules.
How many statements should I send before collections?
There is no fixed number. Many practices send three or four statements with a phone call before sending an account to collections, but follow your own policy and state requirements.
