Strategies for Resolving Legacy AR in Orthopedic Practices

Legacy accounts receivable in orthopedic practices is almost always layered across several years. Old system transitions, surgical claims missing implant details, workers’ compensation cases awaiting adjuster updates, and global period overlaps all contribute to backlogs that behave differently from current-day AR.

Orthopedic encounters involve multiple procedure lines, device charges, and documentation from different sources (surgery centers, imaging, PT, referring providers). When these elements don’t align, claims move into the 90–120+ day category and become progressively harder to trace.

Legacy AR is not a speed issue, it is a structure issue.

Common Reasons Legacy AR Builds Up in Orthopedic Practices

Even when a practice runs efficient day-to-day billing, older orthopedic claims gather complexity due to:

• Multi-procedure surgeries requiring precise modifier logic
• Implant and device billing reliant on accurate invoice matching
• Global period timelines that vary by procedure and limb
• Workers’ comp and auto carriers with separate documentation workflows
• Outdated payer edits from prior PM/electronic systems
• Unposted EOBs or incomplete encounters during older staff transitions
• Secondary claims that were never billed due to missing primary EOBs

These elements create a backlog that needs reconstruction rather than simple follow-up.

6 Steps to Clear Legacy AR In Orthopedics

Creating a Clear Picture of the Legacy AR Backlog

The first step in legacy AR cleanup is creating clarity, not calling payers. To build a stable base:

• Pull aging reports segmented by payer, DOS, and CPT type
• Compare prior PM/EHR data to confirm encounter completeness
• Identify missing charges or documentation gaps
• Separate fully denied claims from partially paid ones
• Group claims with potential timely filing considerations
• Categorize claims by financial class (commercial, Medicare, WC, auto, etc.)

A reliable AR map prevents wasted hours later in the process.

Prioritizing Orthopedic Claims With the Highest Recovery Potential

Instead of working legacy AR chronologically, prioritizing by recovery potential creates momentum and clarifies workload.

High-yield categories include:

• High-value orthopedic surgeries (TKR, THR, arthroscopy, spine)
• Claims involving implants or surgical hardware
• Workers’ comp and auto claims requiring adjuster communication
• Claims tied to global period confusion
• Documentation-dependent claims needing op notes, imaging, or PT records
• Secondary claims awaiting primary EOB posting

Organizing the backlog this way keeps the work methodical and predictable.

Reconstructing Old Orthopedic Claims for Accurate Reprocessing

Older claims must be rebuilt carefully. A structured investigation includes:

• Ensuring complete documentation (op notes, invoices, post-op notes)
• Verifying orthopedic modifier accuracy (RT, LT, 50, XS, 59, XU, FX, FY, FZ)
• Matching billed units with documentation
• Reviewing payer-specific bundling rules
• Checking for missing EOBs from earlier systems
• Confirming implant details align with surgical notes
• Validating medical necessity based on payer criteria

This detailed approach allows each claim to move toward resolution without repeated rework.

Building a Payer Follow-Up Strategy for Orthopedic Legacy AR

When working older claims, a predictable payer-calling order helps gather complete information in a single call. Effective sequences include:

• Confirming claim status
• Reviewing documentation used for processing
• Identifying exact processing notes
• Clarifying correction or reconsideration pathways
• Checking if the claim qualifies for reprocessing
• Confirming appeal requirements and allowable timelines
• Requesting archived payer notes for older DOS

This prevents circular follow-up and reduces duplicate work.

Building an Orthopedic-Specific Documentation Checklist

A strong documentation checklist eliminates delays. Orthopedic claims typically require:

• Complete operative reports
• Imaging results (X-ray, MRI, CT)
• Implant/device invoices with serial and lot numbers
• Post-op visit documentation for global period verification
• Physical therapy orders when required
• Workers’ compensation adjuster and case manager details
• Referring provider notes supporting medical necessity
  

Having these items accessible accelerates corrections, reconsiderations, and appeals.

Appeal Strategies that Work for Orthopedic Legacy Claims

Orthopedic surgeries produce complex claim structures, making appeals more documentation-heavy than in many other specialties.

Useful appeal strategies include:

• Filing corrected claims for modifier or coding adjustments
• Using detailed clinical notes to demonstrate multi-procedure necessity
• Adding implant documentation to support hardware billing
• Referencing global period rules for postoperative care
• Including imaging proof when required by payer policies
• Aligning appeal packets with payer-specific medical policies
• Building complete WC/auto documentation bundles

Well-organized appeals increase the likelihood of closure, even for older dates of service.

Using Technology to Streamline Orthopedic Legacy AR Cleanup

Technology plays a key role in preventing repetitive work. Techniques that streamline cleanup include:

• Reviewing audit logs for deleted or unsubmitted claims
• Tagging claims missing crucial fields
• Grouping denial codes to spot patterns
• Building payer-specific worklists
• Tracking follow-up timelines by payer type
• Ensuring clearinghouse reports match PM submission records

Process Improvements to Prevent Future Legacy AR

Orthopedic practices benefit from prevention-focused workflows such as:

• Coding, billing huddles for documentation alignment
• Standardized implant documentation forms for OR teams
• Clear workflows for global period handling
• Daily reconciliation of charges and documentation
• Ensuring imaging and surgical notes are correctly linked
• Enhanced front-desk intake for WC/auto cases
• Periodic reviews of high-value procedure claims
  

How experienced AR partners like AnnexMed help resolve large backlogs?

Large orthopedic backlogs often require additional capacity. Legacy claims linked to older systems, surgical implants, or extended global periods need focused, uninterrupted attention that internal teams cannot always allocate.

External AR partners such as AnnexMed are familiar with orthopedic patterns and bring structured processes for:

• Reconstructing claim histories across multiple systems
• Identifying recovery opportunities based on payer behavior
• Reviewing orthopedic coding and modifier combinations
• Managing workers’ comp and auto follow-up cycles
• Handling documentation corrections for older surgical cases
• Resolving high-volume follow-up without disrupting daily billing
• Providing clear progress reporting while internal teams handle current work
  

Outside help becomes useful when:

• Legacy AR spans multiple fiscal years
• Backlogs involve surgeries with implants
• Documentation gaps require extensive reconstruction
• Workers’ comp cases need consistent adjuster communication
• EHR migrations created unlinked or incomplete claims
• Internal teams need to protect current-day AR while the backlog is cleared

The goal is not staff replacement; it is backlog stabilization.

Legacy AR in orthopedic practices requires structured, disciplined workflows due to the complexity of surgical procedures, devices, global periods, and payer-specific rules. When claims are segmented properly, investigated methodically, supported with complete documentation, and followed up with a clear strategy, even older backlogs can be resolved systematically.

Consistent prevention processes ensure the practice maintains a clean AR moving forward, while targeted external support can accelerate the resolution of older claims when necessary.
