Behind the results
How Quest Supported the Revenue Cycle
The financial gains were supported by hands-on revenue cycle work across payment posting, payer follow-up, denial management, accounts receivable, and reporting.
Where we started
Aging Accounts, Delayed Submissions, and a 63% Collection Rate
Prior to the partnership, the practice was generating approximately $5.8 million annually. Aging accounts and delayed submissions were limiting collections, creating an opportunity to improve the revenue cycle and recover more of the revenue already being billed.
Improving payer-side collections
20.74% Growth in Average Insurance Payments
Average insurance payments increased from $366,532.40 to $442,560.63 per month – an improvement of $76,028.23. This represented the largest component of the practice’s overall payment growth.
After the Athena transition
The Software Changed. The Work Didn’t Disappear.
After the practice transitioned to Athena, Quest continued performing extensive manual work required to move payments and claims through the revenue cycle.
This included retrieving and posting EOBs, handling virtual credit cards, posting unapplied patient payments, locating missing EOBs, checking payment status, and supplying payment documentation to Athena.
More than half of posted insurance payments
Quest Supplied 55%-56% of Payment Documentation in Two Consecutive Months
In June 2025, $539,280.27 in insurance payments were posted. Quest supplied $294,757.76 of the payments and supporting EOB information for Athena to post – 55% of the month’s total.
In July 2025, Quest supplied $264,101.61 of $469,725.06 in posted insurance payments – 56% of the month’s total. According to the case study, without this work the associated claims would have remained in an unpaid status.
Accounts receivable management
Persistent Follow-Up on High-Value and Aging Accounts
Quest managed appeals, payer portal research, live payer calls, medical-record submissions, and ongoing A/R review. The internal A/R report was updated twice per month and prioritized according to aging, dollar value, and client needs.
The case study notes that payer calls can require one to two hours because of hold times, transfers, and limits on how many claims can be discussed during a single call.
Visibility and accountability
Regular Reporting Kept the Practice Informed
Quest provided regular and as-needed meetings, weekly referral and client-assist reporting, and customized month-end reports. Reporting included charges and payments by provider and system, along with detailed Xolair reporting by provider, units, CPT, charges, and payments.
J-code collections
Tracking Performance Through a Major System Transition
For J-codes, the case study reports a 79% collection rate for January 2024 through March 2025 while the practice was working through eClinicalWorks. For March through August 2025 following the transition to Athena, the reported J-code collection rate was 58%.
The case study does not establish the software transition as the cause of the change. Instead, it documents the additional manual payment posting and follow-up work Quest continued to perform after Athena took over.
The in-house alternative
Estimated Minimum Annual Savings of $72,369
The case study estimates that replacing Quest’s current staffing with five in-house resources at an average wage of $25 per hour would cost approximately $24,000 per month including benefits.
Quest’s average monthly cost was reported at $17,969, producing an estimated minimum annual savings of $72,369 compared with that in-house staffing model.
Billing software can process claims. Revenue cycle performance still requires follow-through.
Quest National Services supports the hands-on work required to turn submitted claims into collected revenue.

The bottom line
More Revenue. Stronger Collections. Measurable Net Value.
Over 22 months, the practice generated $1,685,025.83 in additional revenue compared with its pre-Quest baseline. After Quest’s service costs, the reported net increase in value was $1,249,310.53.
Moving forward, the case study states that J-codes will be carved out for future billing at a reduced fee, lowering the cost to 1% of collections and saving the practice approximately $1,300 per month in Quest billing.
