The Complexity of Orthopedic Coding
Orthopedic surgery involves some of the most complex CPT coding in medicine โ fracture care packages, global surgery periods, bilateral procedures, add-on codes, and implant billing all create opportunities for both errors and revenue optimization.
Global Surgery Periods
Most orthopedic surgical procedures include a 90-day global period โ meaning routine post-operative care is bundled into the surgical fee. Billing a separate E/M visit during the global period (without the right modifiers) results in denial. Common modifiers for global period billing:
- Modifier 24 โ Unrelated E/M during global period
- Modifier 25 โ Significant E/M on same day as procedure
- Modifier 58 โ Staged procedure
- Modifier 79 โ Unrelated procedure during global period
Fracture Care Coding Essentials
Fracture care CPT codes include the initial care, subsequent care during healing, and removal of any device. Key considerations: coding closed vs. open treatment, with or without manipulation, and the appropriate E/M visit level if the fracture was diagnosed in this encounter (modifier 57).
Joint Injection and Aspiration Coding
Joint injections (CPT 20600-20611) and arthrocentesis codes are commonly billed in orthopedics. The correct code depends on the joint (small, intermediate, major) and whether ultrasonic guidance was used. Ultrasound guidance (76942) can be billed separately when documented appropriately.
Workers' Comp Orthopedic Billing
Workers' compensation claims follow state-specific fee schedules and require separate authorization from standard health insurance. First report of injury, treatment plans, and regular progress reports are required. A dedicated virtual biller handles the distinct workers' comp workflow while maintaining your standard billing stream.
