Orthopedic CPT Code Categories
Orthopedic billing covers one of the widest ranges of CPT codes in medicine, spanning office-based E/M visits, diagnostic imaging interpretation, in-office procedures, and major surgical cases. A single orthopedic practice may bill codes from the 20000 musculoskeletal series (fracture care, joint injections), the 27000-29999 range (lower extremity and casting/splinting), and the 99202-99215 E/M series. Understanding which codes generate the most revenue and where billing errors occur most frequently is essential for practice profitability.
Surgical Procedure Codes
Orthopedic surgery codes represent the highest-value claims in the specialty. Total knee arthroplasty (27447) reimburses approximately $1,400 under Medicare for the surgeon fee. Total hip arthroplasty (27130) reimburses approximately $1,500. Arthroscopic knee surgery (29881 for meniscectomy) reimburses approximately $550. Rotator cuff repair (23412) reimburses approximately $900.
Surgical billing requires attention to global periods. Most major orthopedic surgeries have a 90-day global period during which routine post-operative visits are included in the surgical fee. E/M visits during the global period are only separately billable if they address an unrelated condition (modifier 24) or are for a complication requiring a return to the OR (modifier 78).
Fracture Care Codes
Fracture treatment codes depend on the treatment method (closed vs. open reduction), the bone involved, and whether manipulation was performed. Closed treatment of a distal radius fracture without manipulation (25600) reimburses approximately $280. With manipulation (25605), it reimburses approximately $450. The distinction between “with manipulation” and “without manipulation” is one of the most commonly undercoded areas in orthopedics.
Fracture care includes a global period that covers the initial treatment and routine follow-up visits. The global period varies by code: most closed fracture treatments have a 90-day global, while simple fracture care without manipulation may have a shorter global or no global period depending on the specific code.
Joint Injection Codes
Joint and soft tissue injection codes generate consistent in-office revenue. Large joint injection (20610) reimburses approximately $75 for the injection procedure. Intermediate joint injection (20605) reimburses approximately $60. Small joint injection (20600) reimburses approximately $50. The drug administered (corticosteroid, hyaluronic acid, PRP) is billed separately using the appropriate J-code.
E/M Visits in Orthopedics
Orthopedic E/M visits frequently involve moderate to high complexity decision-making because patients present with injuries, surgical planning needs, and post-operative complications. Level 4 established patient visits (99214) should represent 40% to 50% of orthopedic E/M volume, higher than primary care. Practices billing 60%+ level 3 visits are likely undercoding the complexity of orthopedic evaluations.
Casting and Splinting Codes
Application of casts and splints generates additional procedure revenue. Short arm cast (29075) reimburses approximately $65. Long arm cast (29065) reimburses approximately $80. Short leg cast (29405) reimburses approximately $70. These codes are billed in addition to the fracture treatment code when the provider applies the cast or splint as part of the initial treatment.
