Orthopedic Surgery Billing Services
Orthopedic surgery billing combines high-dollar surgical codes with a relentless volume of office visits, injections, imaging interpretations, and DME prescriptions — each with its own coding rules. The surgical side spans total joint arthroplasty (27447, 27130), arthroscopic procedures (29880-29889), fracture fixation (27235-27248), and spine surgery (22551-22634), where a single case can involve 5-8 separately billable codes. The office side generates revenue through joint injections (20600-20611), fluoroscopic-guided procedures, casting and splinting, and the E/M visits that drive patient volume. Optimizing both sides simultaneously is what separates average orthopedic billing from excellent.
The implant and device coding layer adds substantial complexity. Total joint replacements involve laterality (modifier LT/RT), implant-specific codes, and increasingly, robot-assisted surgery add-ons. Fracture care uses a separate coding convention where the initial treatment code includes a 90-day global period that bundles all follow-up care — but complications, hardware removal, and conversion to operative treatment are separately billable with the right modifiers. And the shift toward ambulatory surgery centers (ASCs) for total joints has created a split-billing model where facility and professional fees must be coordinated.

Orthopedic Surgery billing challenges we solve every day.
Orthopedic Surgery is one of the most complex specialties to bill. High-value procedures, strict documentation requirements, and frequent payer policy changes mean even experienced in-house billers miss revenue. For coding standards, see the American Academy of Orthopaedic Surgeons.
Global Surgical Period and Fracture Care Bundling
Orthopedic surgical codes carry 90-day global periods, and fracture management codes include an even more nuanced bundling convention: the initial treatment code covers all expected follow-up care, cast changes, and X-ray reviews for the healing period. The revenue risk cuts both ways. Billing a follow-up visit within the global period when it’s included wastes time and triggers denials. But missing separately billable events — a complication visit (modifier 24), an unplanned return to the OR (modifier 78), or a staged procedure (modifier 58) — leaves legitimate revenue on the table. Evolution tracks every patient’s global period and evaluates each encounter for separate billability.
Implant and Laterality Coding
Total joint claims require laterality modifiers (LT/RT) on every procedure and implant code. Missing laterality causes automatic denial. Beyond modifiers, the implant itself may require additional codes — cemented vs. uncemented components, computer-assisted navigation add-ons, and robot-assisted surgery codes. When revisions involve removing old hardware and placing new components, both the removal and reimplantation must be captured as separate procedures. Evolution validates laterality, implant codes, and surgical approach modifiers on every joint replacement claim.
Injectable Biologics and Prior Authorization
Orthopedic offices perform high volumes of injections — corticosteroids, hyaluronic acid (viscosupplementation), platelet-rich plasma (PRP), and amniotic tissue products. Each has wildly different coverage rules. Hyaluronic acid injections (J7321-J7327) require prior authorization from most payers and are limited to specific numbers of injection series per year. PRP is not covered by Medicare and most commercial payers. Amniotic products face increasing scrutiny and denials. Evolution manages the prior auth workflow for covered injectables, bills non-covered services with proper ABN/financial liability documentation, and ensures drug J-codes match the actual product administered.
Multi-Procedure Surgical Sessions
Orthopedic surgeons frequently perform multiple procedures in a single operative session — ACL reconstruction with meniscectomy, rotator cuff repair with subacromial decompression and biceps tenodesis, or bilateral carpal tunnel releases. Each combination triggers multiple-procedure payment reductions and NCCI bundling edits. Some code pairs are inherently bundled (subacromial decompression with rotator cuff repair), while others are separately reportable with modifier 59. Knowing which procedures bundle and which don’t — and sequencing codes to maximize the primary procedure payment — directly impacts reimbursement. Evolution optimizes code sequencing and modifier application for every multi-procedure case.
