Physical Therapy Monthly Billing Reconciliation for Virtual Assistants

Billing errors do not announce themselves. A claim gets filed, the payment posts, and the difference between what was billed and what was paid gets buried in a column no one looks at. By the time the clinic owner notices, months of write-offs have accumulated into a revenue problem that looks bigger than it is - because a lot of it is recoverable.

A VA who runs a disciplined monthly billing reconciliation prevents that gap from growing. This article covers the full reconciliation workflow, which tools to use, and what to do when numbers do not match.

What Monthly Billing Reconciliation Covers

Reconciliation is not just checking whether claims were paid. It covers:

• Claim status - which claims are paid, pending, denied, or rejected
• Payment accuracy - whether the amount paid matches the contracted rate
• Patient balance aging - overdue patient balances that need collection action
• Write-off audit - whether adjustments are appropriate or represent revenue leakage
• Insurance payment posting - whether payments in the practice management system match deposits in the bank account

Most PT clinics use WebPT for billing, Jane App for practice management and billing, or a standalone biller. The VA needs read access to whichever system the clinic uses plus read access to QuickBooks for the banking reconciliation.

Step-by-Step Reconciliation Workflow

Run this process on the first three business days of each month for the previous month's data.

Day 1: Pull the aging report. In WebPT or Jane App, generate the accounts receivable aging report. This report shows all outstanding balances bucketed by age: 0-30 days, 31-60 days, 61-90 days, and 90+ days. Export it to a spreadsheet. Anything over 60 days is a problem. Anything over 90 days requires immediate action.

For the 31-60 day bucket: check claim status in the payer portal. Was the claim received? Is it pending or was it denied?

For the 61-90 day bucket: call the payer if the claim is not in their system or if the denial reason has not been actioned.

For the 90+ day bucket: escalate to the billing lead or clinic director. Some of these will become bad debt, but many are recoverable with a denial appeal or a corrected claim.

Day 2: Audit denied and rejected claims. Pull the denial report from WebPT's billing dashboard or the clearinghouse (Availity, Trizetto, or Office Ally). Categorize each denial by reason code:

• CO-4, CO-5: Missing or invalid modifier. Correct and refile.
• CO-29: Claim expired. Check whether within the filing limit and appeal if so.
• CO-97: Service included in another service. Bundle code issue - flag for the billing lead.
• PR-1, PR-2: Patient deductible or copay. Bill the patient directly.
• CO-50, CO-57: Not medically necessary. Gather clinical documentation and submit an appeal with supporting notes.

The VA handles the administrative denials (modifiers, timely filing, duplicate claim). Clinical necessity denials require the therapist's input and go to the billing lead. Do not sit on denials - most payers have appeal deadlines of 90 to 180 days from the original remittance date.

Day 3: Reconcile payments against the bank. Export the payment posting report from WebPT or Jane App. Compare insurance payment totals by date against the corresponding bank deposits in QuickBooks. Line items should match. If they do not, the discrepancy is either a posting error in the practice management system or a bank deposit that was not entered correctly.

Log every discrepancy in a reconciliation worksheet. For discrepancies over $100, flag for the clinic director. For discrepancies under $100, investigate and correct within the same reconciliation cycle.

Common Reconciliation Findings and How to Handle Them

Contractual adjustment errors. The payer paid less than the contracted rate. Pull the Explanation of Benefits (EOB) and compare against the clinic's fee schedule. If the payer underpaid, file a corrected remittance dispute. Keep a log of systematic underpayments by payer for contract renegotiation.

Patient balances not billed. The insurance paid, but the patient's portion was never billed. Run a patient statement report and confirm all patient balances have statements generated in the current month. Set up automatic statement generation in WebPT if it is not already running.

Write-offs without approval. Look for adjustments in the system that do not match the clinic's write-off policy. Common culprits: timely filing write-offs that could have been appealed, write-offs for services that were never actually denied. Flag these for the director.

Double payments. Rare but real. A claim pays, and then the same claim pays again (or pays and the patient also pays). Mark any suspected double payments immediately and initiate a refund process.

QuickBooks Reconciliation Steps

After the EMR reconciliation, reconcile the bank account in QuickBooks:

1. Open the bank account register and go to the reconciliation tool.
2. Enter the closing balance from the clinic's bank statement.
3. Match each transaction in QuickBooks against the statement.
4. All insurance deposits from the EMR should appear as categorized income deposits.
5. Any unmatched transactions require investigation before finalizing.

If the VA does not have full-access QuickBooks permissions, provide them with the reconciliation report from the EMR and have the bookkeeper run the bank reconciliation independently, using the VA's report as input.

FAQ

Does the VA need billing certification to run reconciliation? Not for the administrative portions: aging reports, claim status checks, denial categorization, and payment posting comparison. For appeals and corrected claims that involve coding decisions, yes - either use a certified biller or have the VA work under one. The VA handles the tracking and routing; the certified biller handles the clinical coding decisions.

How often should reconciliation run? Monthly minimum. For clinics seeing more than 100 patients per month, run a mini-reconciliation weekly: check the denial queue, review any 60+ day items, and confirm payment posting is current. This prevents month-end surprises.

What is the most common source of revenue leakage in PT billing? Uncollected patient balances. Insurance pays, but the patient's copay or deductible balance never gets collected because no one followed up. A VA running monthly aging report reviews and weekly patient statement audits closes this gap. See how to hire a fitness virtual assistant for more.

Can a VA handle billing appeals? Administrative appeals (timely filing, duplicate claim, missing modifier) yes. Clinical necessity appeals require the therapist to provide a letter of medical necessity or additional documentation. The VA prepares the appeal packet and routes it to the therapist for the clinical narrative.
