Precision Billing for High-Impact Surgery.
Orthopedic billing services span everything from office fracture care to joint replacement to complex spine surgery — with 90-day global periods, multiple procedure reductions, and workers’ compensation billing adding layers of complexity at every turn. Generic billing teams leave money on the table with every case.
In orthopedics, the 90-day global period is where most revenue leaks begin.
The global surgical package for major orthopedic procedures bundles pre-operative evaluation, intraoperative services, and 90 days of post-operative care into a single payment. That means every office visit, suture removal, and complication management during the global window is included — unless the right modifier is applied. Joint replacements (27447 for TKA, 27130 for THA), spine procedures (22551–22558 for cervical; 22612–22614 for lumbar), and fracture care (25600–25609 for wrist; 27230–27248 for hip) all carry this 90-day burden. When a patient develops a new, unrelated condition during the global period, modifier -79 opens a separate billing window. When complications require a return to the OR, modifier -78 applies. Omit these modifiers, and the additional service pays nothing. Our full RCM services are built for this complexity.
Global Period Management: Modifiers -58, -78, -79, -24
Four modifiers govern post-operative billing in orthopedics. Modifier -58 covers staged procedures planned at the time of the original surgery (new global period begins). Modifier -78 covers unplanned return to the OR for a complication (reimbursement at intraoperative value only — no new global period). Modifier -79 covers a completely unrelated procedure during the original global period (new global period begins). Modifier -24 covers E/M visits during the global period that are unrelated to the surgical diagnosis. Missing or misapplying any of these converts a billable service into a zero-pay bundled claim.
Arthroscopy vs. Open Procedure Coding
Arthroscopic procedures (29800–29999) and equivalent open procedures are not interchangeable — and cannot be billed together for the same joint in the same session. When an arthroscopic procedure converts to open, only the open code is billed; the arthroscopic approach is included. When multiple arthroscopic procedures are performed in the same joint (e.g., ACL reconstruction plus meniscectomy), NCCI edits apply and the combination must be reviewed for bundling before billing. Each compartment of the knee has its own code; laterality modifiers (-LT, -RT) are required on every procedure involving bilateral structures.
Workers' Compensation Billing
Workers' compensation is a significant revenue source for orthopedic practices — and it follows entirely different billing rules from commercial insurance. State-specific fee schedules govern reimbursement (not the Medicare fee schedule). First-fill medication rules, return-to-work documentation requirements, and independent medical examination (IME) billing add administrative complexity. Many orthopedic practices undervalue their workers' comp revenue because their billing team treats it like regular commercial insurance.
DME and Orthotic Billing
Post-operative braces, orthotics, and durable medical equipment represent additional revenue for orthopedic practices that supply these in-office. L-codes govern orthotic billing; HCPCS codes govern DME. Prior authorization is required from most commercial payers before DME is dispensed — and documentation of medical necessity must support the specific device type and code selected. Billing the wrong L-code for a custom versus prefabricated orthosis is both a coding error and a compliance risk.
Happy Billing Benchmarks for Orthopedics:
98%+ First-Pass Clean Claim Rate
Orthopedic claims fail most often on global period modifier errors, wrong arthroscopy/open code combinations, and missing laterality modifiers. We catch all three before the claim leaves our system.
Zero Revenue Lost in the Global Period
We track the global period for every surgical procedure and automatically flag post-operative encounters for modifier review — preventing both bundling errors and compliance exposure from incorrect unbundling.
Workers' Comp Revenue Optimization
Workers’ comp claims are reviewed against the applicable state fee schedule and work comp-specific billing rules — not just the Medicare fee schedule. State-specific documentation requirements are confirmed before submission.
A/R Under 35 Days
Orthopedic practices carry wide procedure value ranges — from office fracture care to six-figure joint replacement episodes. Our 24/7 team prioritizes high-dollar claims while keeping the full A/R aging in check.
Our Specialized Process
Surgical Global Period Tracking
We assign global periods to every surgical procedure and maintain a real-time tracking log of post-operative encounters, modifiers, and eligible separately billable services. No post-op revenue is accidentally bundled, and no modifier is missing when a patient returns to the OR or presents with an unrelated condition.
Multiple Procedure and NCCI Review
Every claim with multiple procedures is reviewed against the NCCI edit table for the correct multiple procedure reduction (modifier -51) and any applicable NCCI PTP edits. This prevents both the automatic denial of secondary codes and the compliance risk of incorrect unbundling.
Workers' Comp and Auto Claim Management
We apply state-specific fee schedules, first-fill rules, and return-to-work documentation requirements for all workers' compensation and auto insurance claims. Workers' comp revenue is treated as a separate, optimized revenue stream — not an afterthought.
DME and Orthotic Authorization
We manage prior authorizations for in-office DME and orthotics, confirm L-code and HCPCS code selection against the device dispensed, and handle documentation of medical necessity. No brace or orthotic leaves your office without a confirmed coverage path.

Frequently Asked Questins
How do you handle workers' compensation billing alongside commercial insurance?
Workers’ compensation follows entirely different rules — state-specific fee schedules, first-fill medication requirements, return-to-work documentation, and work comp-specific claim forms (CMS-1500 with specific field requirements). We maintain a payer matrix for every state in which your practice treats work comp patients and apply the correct fee schedule, documentation requirements, and billing rules to every claim.
