Orthopedic Billing — Built for Your Practice
A single total knee arthroplasty generates charges spanning the professional fee, facility fee, implant cost passthrough, anesthesia, and often post-operative therapy — and every one of those pieces has its own coding rules, its own payer, and its own timeline. Miss the right modifier on any of them and the claim doesn't just underpay, it can trigger a full implant denial or a payer audit.
Our orthopedic billing team works exclusively from operative reports. Your surgeons never touch a charge sheet — we pull the procedure directly from the op note, verify every modifier, and submit a clean claim within 24 hours of the case.
The result: a first-pass acceptance rate above 98% and an average collection rate that outperforms in-house billing by 12–18 percentage points.
What's Costing Orthopedic Practices Money Right Now
These are the specific, avoidable spots where orthopedic revenue quietly disappears before a claim ever gets appealed.
A post-op E&M visit billed during the 90-day global period without modifier -24 or -25 gets auto-denied by every payer — CMS tracks the global window against your NPI automatically.
A facility claim for a joint implant missing the supplier invoice gets denied for the implant cost entirely — no invoice, no payment, on a charge that can run into the thousands.
A workers' comp claim submitted on the wrong form for that state's jurisdiction gets rejected without processing — and every state has different rules.
Modifier -51 left off a secondary procedure on a multi-procedure operative day triggers full-value payment on all procedures, which becomes a payer audit and recoupment demand later.
The same procedure billed in the wrong setting — office, ASC, or hospital outpatient — can cost thousands per case in the reimbursement-rate gap between settings.
Co-surgeon and assistant surgeon roles billed with the wrong modifier on a multi-surgeon case get underpaid or denied outright.
Top Orthopedic Claim Denial Reasons — and How We Eliminate Them
Most Orthopedic denials are preventable. Our team knows exactly what to look for before submission.
❌ Global Period Modifier Not Applied
E&M visits during a 90-day post-op global period billed without modifier -24 or -25 are automatically denied by all payers. CMS tracks global periods by provider NPI and procedure date.
✓ Our Fix
Every surgery in our system triggers an automatic global period flag. We track the 0/10/90-day window for every procedure and apply the correct modifier (-24 for unrelated E&M, -25 for same-day significant E&M, -79 for unrelated procedure) without exception.
❌ Implant Invoice Not Attached to Facility Claim
ASC and hospital outpatient facility claims for joint implants, spinal hardware, and other high-cost devices require the actual supplier invoice as supporting documentation. Missing it = 100% implant denial.
✓ Our Fix
We have a standing request workflow with OR and supply chain teams at every client practice. Implant invoices are collected within 24 hours of surgery, reviewed for pricing, and attached to facility claims before submission.
❌ Workers' Comp Jurisdiction Form Error
Workers' compensation claims submitted on CMS-1500 to a state that requires its own form, or vice versa, are rejected without processing. Each of the 50 states has specific requirements.
✓ Our Fix
Our workers' comp billing team maintains updated jurisdiction rules for all 50 states. Every WC claim uses the correct form, fee schedule, and authorization pathway for the specific state jurisdiction.
❌ Multiple Procedure Modifier -51 Missing
When billing two or more surgical procedures during the same operative session, modifier -51 must be appended to secondary procedures. Omitting it results in full-value payment on all procedures, triggering a payer audit and recoupment.
✓ Our Fix
We apply the multiple procedure rule correctly on every surgical claim, reducing the secondary procedure by the appropriate percentage and using modifier -51 as required — while also knowing which codes are exempt from -51.
Our Orthopedic Billing Process, Start to Finish
Operative Report Charge Capture
Every procedure is coded straight from the operative report — never a charge sheet — with the correct primary code, bilateral/multiple procedure modifiers, and implant documentation attached before submission.
Eligibility & Prior Authorization
We verify coverage and secure authorization for scheduled surgical cases and workers' comp treatment plans across all 50 state jurisdictions before the case is performed.
Global Period & Modifier Compliance Audits
Every surgery triggers a 0/10/90-day global period flag, and every post-op visit or additional procedure is checked for the correct modifier — -24, -25, -79 — before the claim goes out.
Denial Prevention & Recovery
Implant invoices are collected and attached to every facility claim, workers' comp claims are matched to the correct state form and fee schedule, and any denial that still occurs gets corrected and appealed.

Each procedure in our system carries its own global period flag — 0, 10, or 90 days depending on the CPT code. When a patient has multiple procedures or returns for treatment during any active global window, our system automatically routes the claim through a modifier review workflow. No global period violation has ever been missed in our system since we implemented this protocol.
For joint replacements and spinal hardware, we require the vendor invoice showing the actual cost per implant (not a catalog price) and the product name/lot number. For ASC facility claims, this is attached directly to the UB-04. For hospital outpatient claims, it goes to the outpatient prospective payment system. We coordinate this with your OR staff and typically have it within 24 hours of the case.
Yes. Co-surgeon (-62), assistant surgeon (-80, -81, -82), and teaching physician billing rules all apply differently depending on the payer, setting, and roles. We correctly bill each surgeon's involvement — primary surgeon, co-surgeon, first assist — with the appropriate modifier and fee schedule.
Workers' comp spine billing combines the complexity of spinal surgery coding with workers' comp jurisdiction rules. We handle both sides: the correct CPT coding for multi-level fusions, decompression, and interbody device billing, AND the state-specific WC authorization, fee schedule, and form requirements. All 50 states covered.
Standard operative report turnaround is 24 hours. Same-day ASC cases can be turned around in 4 hours with advance notice. High-volume practices with 15+ cases per day typically see 100% of cases coded and submitted by 11 AM the following business day.
When two or more surgical procedures happen during the same operative session, modifier -51 must be appended to the secondary procedures — omitting it results in full-value payment on all procedures, which triggers a payer audit and recoupment request later rather than a clean denial upfront. Bilateral procedures use modifier -50 and are reimbursed differently than two separate unilateral procedures. Modifier -59 (or the more specific X{EPSU} modifiers) applies only when a procedure is genuinely distinct and separately identifiable, not as a default override to force separate payment. We also know which codes are exempt from -51 entirely, which is where a lot of generalist billers get it wrong.
Yes, significantly. The same orthopedic procedure reimburses at a different rate depending on where it's performed — office, ambulatory surgery center (ASC), or hospital outpatient department (HOPD) — because each setting has its own fee schedule and facility-fee structure. Billing a case as if it happened in the wrong setting, or failing to bill the facility fee separately from the professional fee when a case moves to an ASC or HOPD, costs a practice thousands of dollars per case in the rate difference. We verify the correct place-of-service code for every claim before submission.
