Direct Answer
Orthopedic and spine billing has among the highest complexity in medical coding — procedures have 90-day global periods that determine when post-operative E&M services can be separately billed, fracture care codes encompass weeks of follow-up treatment, spinal procedures have specific instrumentation add-on codes, and joint replacement increasingly falls under CMS bundled payment programs. Getting orthopedic billing right requires knowing the global period implications, correct fracture care vs. separate services, and the detailed anatomy of spinal surgery codes.

Orthopedic 90-Day Global Periods
Most orthopedic surgical procedures carry a 90-day global period — meaning the surgical fee includes one pre-operative day, the intraoperative services, and all routine post-operative care through 90 days after the procedure. E&M services related to the surgical condition during the global period are included in the surgical payment and cannot be separately billed. E&M services that are unrelated to the surgery, or that address a new problem that was not anticipated at the time of the surgery, can be separately billed with Modifier 24. Services for complications of the surgery are also included in the global period — but complications requiring a return to the operating room are separately billable with Modifier 78.
Orthopedic practices should maintain tracking of surgical dates and 90-day global period end dates for each patient to ensure E&M services are not billed within the global period when they should be included, and to capture legitimate separate billing (new problems, unrelated care) using Modifier 24 when appropriate.
Fracture Care Coding
Fracture care CPT codes (2XXXX range) include the initial assessment plus follow-up care for the fracture. The fracture care code is all-inclusive for the specific fracture — it includes application and removal of the first cast or splint, and subsequent visits related to the fracture treatment. A separate E&M code can be billed for the initial visit when the provider performs a medically necessary significant, separately identifiable E&M service beyond the fracture care itself (Modifier 25). Separate codes are appropriate for: x-ray interpretation (if reported separately); closed reduction of a displaced fracture; and care of a different fracture or injury during the same visit.
The key distinction between fracture care codes and E&M codes for fracture management: fracture care codes (e.g., 25600 closed treatment of radial fracture without manipulation; 25605 with manipulation) are used when the physician provides definitive fracture care during the encounter. If the fracture is treated by another provider (e.g., the ER physician splints and refers to orthopedics), the orthopedic surgeon should not rebill the fracture care code — only bill for subsequent fracture management visits.
Joint Replacement Billing
Total joint replacement (hip: 27130 total hip arthroplasty; knee: 27447 total knee arthroplasty; shoulder: 23472) involves complex billing considerations: the surgeon bills the professional component; implant/prosthesis costs are typically billed by the facility as a pass-through or included in a DRG; and the procedure has a 90-day global period. CMS's Comprehensive Care for Joint Replacement (CJR) model is a bundled payment model for hip and knee replacement in participating hospitals — under CJR, CMS pays a target episode price that covers all Part A and Part B services for 90 days post-discharge. Participating hospitals are accountable for the total episode cost, creating financial incentives to manage post-acute care carefully. Even in non-CJR markets, commercial payers increasingly use episode-based payment models for joint replacement — orthopedic groups should be aware of any bundled payment arrangements with their major payers.
Spine Surgery Codes
Spinal surgery coding requires selecting from several distinct code families: discectomy/decompression (63001–63048 based on approach and level), laminectomy/laminotomy, fusion (22558–22819 based on approach, levels, and type), and arthroplasty (22856–22861). Fusion procedures have separate add-on codes for each additional interspace or additional vertebral segment fused, for bone graft procedures (20930–20938), and for instrumentation (pedicle screws, interbody cages: 22840–22855 add-ons). The complexity is in correctly identifying: the approach (anterior, posterior, lateral, combined); the number of levels; the type of fusion (interbody, posterolateral); and whether instrumentation was placed. Each of these variables determines which base and add-on codes apply.
Arthroscopy and Sports Medicine Codes
Arthroscopy codes are organized by joint and procedure: knee arthroscopy (29870–29889), shoulder arthroscopy (29805–29828), hip arthroscopy (29860–29863), ankle/elbow arthroscopy. The key rule: when multiple arthroscopic procedures are performed in the same joint at the same surgical encounter, code the most complex procedure and add codes for separately reportable additional procedures — but do not re-bill diagnostic arthroscopy (29870 knee diagnostic) if a surgical procedure was performed (the diagnostic component is bundled into the surgical arthroscopy code). NCCI edits bundle many arthroscopic add-ons — surgical coders must verify which procedures are separately payable vs. bundled with the primary arthroscopy code. Sports medicine injection procedures (corticosteroid joint injections: 20600/20605/20610; hyaluronic acid: G-codes under Medicare) are separately coded and frequently denied for medical necessity without appropriate supporting diagnosis documentation.
FAQ
Can an orthopedic surgeon bill an E&M service on the day of surgery?
The day of surgery is included in the surgical global period — E&M services provided on the day of surgery are generally not separately billable unless: the decision to perform the surgery was made during that E&M visit (Modifier 57 — decision for surgery), or the E&M service was for a completely unrelated problem (Modifier 25 with documentation supporting that the visit addressed a separately identifiable problem unrelated to the surgical condition). The distinction between Modifier 25 (significant, separately identifiable E&M, same day as a minor procedure — 0 or 10 global) and Modifier 57 (decision for surgery, day before or day of a 90-day global procedure) is critical: use 57 for the pre-op decision E&M before a major procedure, 25 for same-day E&M with minor procedures.
How should durable bracing ordered by an orthopedic surgeon be billed?
Durable medical equipment (bracing, orthotics, prosthetics) provided to orthopedic patients is billed differently depending on who provides it. If the orthopedic practice supplies the brace directly to the patient from office inventory, they bill the appropriate HCPCS L-code using their DMEPOS supplier number (requires separate DMEPOS billing enrollment, surety bond, and accreditation). If the practice refers the patient to an outside orthotist or DME supplier, the outside supplier bills. Many orthopedic practices avoid the regulatory complexity of DMEPOS billing and simply refer patients to contracted orthotists/suppliers. Selling braces "in-office" without proper DMEPOS supplier enrollment and billing the insurer is a compliance error — orthopedic practices should confirm their billing arrangements for bracing comply with DMEPOS supplier enrollment requirements.
