Open reduction internal fixation (ORIF)

Open reduction internal fixation (ORIF) is surgery in which an orthopedic surgeon makes an incision to reposition fractured bone fragments and then secures them with hardware—screws, plates, rods, or wires—so the bone heals in correct anatomic alignment.

ORIF combines two distinct surgical actions. 'Open reduction' means the surgeon cuts through skin and soft tissue to directly visualize and manipulate the fracture, returning displaced fragments to their native position. 'Internal fixation' means implanted hardware—most commonly locking plates, cortical screws, intramedullary rods, or Kirschner wires—holds that reduction while bone consolidates. Hardware may remain permanently in place or be removed in a staged second procedure once healing is confirmed.

ORIF is indicated when fracture geometry, displacement, articular involvement, or soft-tissue compromise makes non-operative management unreliable. Common indications include displaced intra-articular fractures, unstable long-bone fractures, open fractures requiring wound access, and fractures associated with neurovascular injury. The operative approach, implant type, and fixation construct are all documentation variables that drive CPT code selection downstream.

From a coding and reimbursement standpoint, each ORIF carries a 90-day global surgery period. All fracture care—routine follow-up, cast or splint applications by the same group, and removal of hardware integral to the procedure—is bundled into the global package. Separately billable services within that window require specific documentation justifying their distinctness from the index procedure.

Why it matters

The choice between closed treatment, open treatment without fixation, and ORIF maps to different CPT codes with materially different RVUs and payment rates. Misclassifying an ORIF as closed treatment—or failing to document the open approach and specific implants used—triggers downcoding, claim denials, and audit exposure. Additionally, the 90-day global period means any service billed during that window must be clearly outside the scope of routine postoperative fracture care or it will be recouped. If a closed reduction attempt fails and converts to ORIF in the same session, only the ORIF is billable under NCCI policy—billing both is an unbundling violation.

Common mistakes

Where people most often go wrong with this concept.

Source · Editorial brief grounded in cited references ↓

Selecting a closed-treatment CPT code when the operative note documents an incision for direct fracture visualization—constitutes downcoding and misrepresents the service.
Omitting the specific bone, fracture site, laterality, and fixation construct from the operative note, making it impossible to assign a site-specific CPT code or the correct ICD-10 7th character.
Billing CPT 20670 or 20680 (implant removal) separately when the removal is a necessary component of the same-session ORIF or a revision procedure—this is an NCCI bundling violation.
Using ICD-10 aftercare code Z47.89 for visits that occur while the fracture is still actively healing and under treatment—Z47.89 is only appropriate once the fracture has healed.
Appending Modifier 51 to add-on CPT codes billed alongside an ORIF, which incorrectly triggers an additional 50% payment reduction on top of the already-reduced add-on reimbursement.
Failing to document the 7th character extension correctly (e.g., 'A' for initial encounter, 'D' for subsequent, 'S' for sequela) in ICD-10-CM fracture codes, resulting in coding errors and claim rejections.
Reporting casting or splinting codes (29000-29750) applied at the conclusion of the ORIF by the same group—post-operative immobilization is included in the global surgical package.
Billing a separate E&M on the same date as the ORIF without appending Modifier 25 and without clear documentation that the E&M was a significant, separately identifiable service unrelated to the decision to operate.

Frequently asked questions

Source · Generated from the editorial pipeline, verified against 8 cited references ↓

01What is the difference between ORIF and closed reduction?

Closed reduction repositions fracture fragments through manipulation without a surgical incision; ORIF requires an incision to directly visualize and access the fracture site before securing the bone with implanted hardware. The distinction is not merely clinical—it determines which CPT code is assigned and the resulting reimbursement level.

02How long is the global period for ORIF?

ORIF carries a 90-day global surgery period. Routine postoperative fracture care, same-group cast and splint applications, and hardware removal integral to the procedure are all bundled into that global payment. Separately billing for those services without appropriate modifier documentation is an NCCI violation.

03Can hardware removal always be billed separately after ORIF?

No. CPT codes 20670 and 20680 for implant removal are only separately reportable when the removal is a distinct, standalone procedure with independent medical necessity. If removal occurs as a necessary step within a revision or other concurrent procedure at the same site, it is bundled and cannot be billed separately under NCCI policy.

04What ICD-10 code is used for routine follow-up after ORIF once the fracture has healed?

Z47.89 (Encounter for other orthopedic aftercare) is appropriate for post-ORIF follow-up visits once the fracture is confirmed healed. It should not be used during active fracture treatment, as this represents a coding error that can trigger incorrect reimbursement and audit risk.

05If a closed reduction fails and ORIF is performed in the same session, how should the encounter be billed?

Only the ORIF CPT code is reportable. Per NCCI policy, when a closed reduction converts to an open reduction at the same patient encounter, only the more extensive open procedure is billable. Reporting both constitutes unbundling.

06Does the operative report need to specify implant type for accurate ORIF coding?

Yes. The specific fixation construct—plate, screw size and count, rod diameter, wire type—is required both for accurate CPT code selection and for implant billing compliance. Generic language such as 'hardware was applied' is insufficient for coding and exposes the claim to downcoding or denial on audit.

Mira AI Scribe

When Mira captures an ORIF encounter, it flags the following documentation requirements to the scribe layer before the note is finalized: 1. APPROACH SPECIFICITY — The note must state that an incision was made and the fracture site was directly visualized. Language like 'percutaneous' or 'under fluoroscopic guidance only' without an incision description will route the case to a closed or percutaneous CPT code, not an open-reduction code. 2. FIXATION CONSTRUCT — Record the exact hardware type (e.g., volar locking plate, 3.5 mm cortical screws, cephalomedullary nail). Implant type affects both CPT selection and implant billing compliance. 3. FRACTURE CHARACTERIZATION — Capture bone, specific anatomic site, laterality, fracture pattern (transverse, comminuted, intra-articular, etc.), and open vs. closed status. These elements determine the correct ICD-10 7th character and site-specific CPT code. 4. CONVERSION RULE — If a closed reduction was attempted and failed in the same session before ORIF, Mira suppresses the closed-reduction CPT to prevent NCCI unbundling. Only the ORIF code is surfaced. 5. GLOBAL PERIOD ALERT — Mira sets a 90-day global period flag at attestation. Any follow-up service during that window will require documentation review before a separate E&M or procedure code is allowed through. Modifier 24 or 79 will be suggested with a documentation prompt when applicable. 6. IMPLANT REMOVAL BUNDLING CHECK — If hardware removal is documented in the same operative session as the primary ORIF or a revision, Mira suppresses CPT 20670/20680 unless the removal is clearly at a separate anatomic site or a distinct separate procedure with independent medical necessity.

Related terms

Closed reduction Clinical

Closed reduction is the non-surgical realignment of a fractured or dislocated bone in which the fracture site is never opened, incised, or directly visualized. It may be performed without manipulation, with manual manipulation, with skeletal traction, or with skin traction.

Percutaneous fixation Clinical

Percutaneous fixation is a minimally invasive technique in which pins, screws, or wires are passed through intact skin and into bone to stabilize a fracture—without surgically opening or directly visualizing the fracture site, typically guided by fluoroscopy or other real-time imaging.

External fixation Clinical

External fixation is a surgical stabilization technique in which pins or wires are anchored into bone and connected to a rigid frame that remains entirely outside the skin, allowing fracture alignment and wound access without an implant buried beneath soft tissue.
