For many small orthopedic and specialty practices across the US, accounts receivable management isn't just a back-office function. It's the lifeline that determines whether you can make payroll, invest in equipment, or keep your doors open. When AR days balloon past industry benchmarks, the ripple effects touch every corner of your practice, from staff morale to patient care quality.
This is the story of how one small orthopedic practice in Michigan turned that around, fast.
The Problem: AR Days at 59, Cash Flow in Crisis
When this Michigan-based orthopedic practice came to PhysiAssist, they were sitting at 59 AR days, nearly double the 30-day benchmark that high-performing practices consistently target. For context, the Healthcare Financial Management Association (HFMA) recommends keeping AR days under 40 for most specialty practices. At 59 days, this practice was in financially dangerous territory.
The root causes weren't unique, but they were compounding rapidly.
Claim delays were stacking up. Insurance companies weren't receiving clean claims, which meant denials, additional documentation requests, and resubmission cycles that stretched payment timelines by weeks.
Manual follow-up was bleeding operational capacity. Billing staff were spending hours each week calling payers, logging statuses in spreadsheets, and chasing down information that should have been automated. That's hours not spent on clean claim submission or denial prevention.
Inconsistent billing cycles created reconciliation nightmares. Without a standardized billing calendar, accounts fell through the cracks. Small discrepancies compounded into significant revenue leakage.
The result was a practice where physicians were working full schedules, seeing patients, performing procedures, generating legitimate revenue, but cash wasn't converting fast enough to sustain operations. This is one of the most painful and underappreciated problems in orthopedic RCM: you can be clinically busy and financially starved simultaneously.
The PhysiAssist Approach: Precision Over Patchwork
Too many RCM vendors respond to high AR days with brute-force solutions, throwing more staff at follow-up queues or outsourcing denial management without fixing upstream processes. PhysiAssist took a different approach, targeting the specific friction points causing this practice's AR to age.
Automated AR Tracking: Eliminating the Spreadsheet Era
The first intervention was replacing manual AR oversight with an automated AR tracking system that flagged aging claims in real time. Rather than waiting for a monthly AR report to identify a 90-day-old claim, the system surfaced issues at 30, 45, and 60-day thresholds, giving the billing team a clear action queue every single day.
For orthopedic practices specifically, this matters enormously. Orthopedic procedures, from joint injections to surgical global periods, carry complex billing timelines. A claim for an arthroscopic procedure that sits untouched for 45 days isn't just delayed revenue. It's a claim rapidly approaching timely filing limits with major payers like BCBS Michigan, Aetna, and Priority Health.
Real-Time Payer Communication: Cutting Out the Phone Tag
Integrated real-time payer communication tools replaced the hours per week staff spent on hold with insurance companies. Claim status updates that previously required manual phone calls were now surfacing automatically, allowing the billing team to prioritize actionable denials rather than status checks.
This shift alone dramatically reduced the average follow-up cycle time, a critical lever in orthopedic RCM where payers frequently request operative reports, medical necessity documentation, and prior authorization confirmations before releasing payment.
Standardized Billing Cycles: Consistency as a Revenue Strategy
PhysiAssist worked directly with the practice's administrative team to build standardized billing cycles with defined submission windows, follow-up triggers, and escalation protocols. This wasn't about software alone. It was about building operational discipline that the team could sustain independently.
Inconsistent billing is one of the most common and most fixable causes of high AR days in small specialty practices. When claims go out on different days, in different batches, without consistent coding review, errors multiply. Standardization compressed that error rate significantly.
Regular Reconciliation: Closing the Revenue Leak
Monthly and bi-weekly AR reconciliations ensured that every discrepancy, including underpayments, contractual adjustment errors, and misapplied payments, was caught and addressed before it aged further. In orthopedic billing, where fee schedules vary significantly across CPT codes for musculoskeletal procedures, reconciliation isn't optional. It's where revenue integrity lives.
The Results: 35 AR Days and a Practice That Breathes Again
Within a defined engagement period, the results were measurable and material:
AR Days dropped from 59 to 35, a 41% reduction that brought the practice into alignment with industry benchmarks
Cash flow improved meaningfully with faster reimbursement cycles converting clinical work into actual revenue within the same month
Operational bottlenecks cleared as the billing team shifted from reactive phone follow-up to proactive denial management
For a small practice, the difference between 59 and 35 AR days isn't just a metric improvement. At even modest monthly charges, shaving 24 days off your AR cycle means hundreds of thousands of dollars in previously locked revenue becomes accessible, money that can fund equipment, staffing, or simply give the physician-owner peace of mind.
Why This Matters for Oncology and Other Specialty Practices
While this case study focuses on orthopedics, the AR management challenges are directly parallel to what oncology practices face. In many ways, the stakes are even higher in oncology RCM.
Oncology billing carries layers of complexity that make AR management uniquely difficult:
Drug administration codes (96413, 96415, 96372) require precise documentation of infusion time and drug units. Errors here create immediate denials.
Prior authorization requirements for chemotherapy and immunotherapy are extensive, and expired auths are a leading cause of AR aging in oncology.
Payer-specific oncology policies, particularly around biosimilars, oral oncolytics, and clinical trial billing, create denial patterns that manual follow-up processes simply cannot catch at volume.
MOOP tracking and patient responsibility estimation failures create secondary AR aging on the patient balance side.
The same core interventions that worked for this orthopedic practice, automation, real-time payer connectivity, billing standardization, and rigorous reconciliation, are precisely what oncology practices need to prevent AR days from spiraling past the 45-50 day threshold that signals a collections crisis.
Is Your Practice Leaving Revenue in Aging AR?
If your current AR days are above 40, or if you're seeing a growing percentage of claims aging past 90 days, the problem won't self-correct. Manual processes don't scale, payer complexity only increases, and every day a clean claim sits unworked is a day closer to a timely filing denial.
PhysiAssist has a proven framework for diagnosing and resolving AR management breakdowns in specialty practices, whether you're running a 3-physician orthopedic group or a multi-site oncology center.
