Orthopedic hardware, such as plates, screws, rods, and pins, is frequently used to stabilize fractures, correct deformities, or support bone healing. However, there are instances where hardware removal becomes necessary due to pain, infection, or mechanical complications. Understanding the correct CPT (Current Procedural Terminology) codes for hardware removal is essential for accurate billing and reimbursement.
This comprehensive guide explores the indications, surgical techniques, coding guidelines, and reimbursement challenges associated with hardware removal. Whether you’re a surgeon, coder, or healthcare administrator, this article provides in-depth insights to ensure compliance and optimize patient outcomes.
CPT Code for Hardware Removal
2. Understanding Hardware Removal in Orthopedics
Hardware removal is a surgical procedure performed to extract previously implanted orthopedic devices. While many implants remain in the body permanently, certain conditions necessitate their removal.
Why Remove Orthopedic Hardware?
-
Pain or discomfort (e.g., irritation from prominent hardware)
-
Infection (osteomyelitis or soft tissue infection around the implant)
-
Hardware failure (broken screws, loose plates)
-
Bone healing completion (elective removal after fracture union)
-
Growth considerations (pediatric patients needing implant removal to avoid growth restriction)
3. Common Indications for Hardware Removal
The decision to remove hardware depends on patient symptoms and clinical findings. Below are the most common reasons:
| Indication | Description |
|---|---|
| Persistent Pain | Patients may experience discomfort due to hardware prominence, especially in areas with thin soft tissue coverage (e.g., tibia, clavicle). |
| Infection | Bacterial colonization of hardware may require removal to eradicate infection. |
| Implant Failure | Broken screws, bent plates, or loosened hardware may necessitate removal. |
| Allergic Reactions | Rare cases of metal hypersensitivity (e.g., nickel allergy) may require removal. |
| Elective Removal | Some patients request hardware removal after complete bone healing. |
4. Types of Orthopedic Hardware and Removal Considerations
Different types of hardware require specific removal techniques:
Common Orthopedic Implants
-
Plates and Screws (e.g., dynamic compression plates, locking plates)
-
Intramedullary Nails (e.g., femoral nails, tibial rods)
-
Kirschner Wires (K-wires)
-
External Fixators
Challenges in Hardware Removal
-
Stripped screws – May require specialized extraction tools.
-
Bone overgrowth – Can make hardware difficult to access.
-
Infected hardware – May need staged removal with antibiotic therapy.
5. CPT Codes for Hardware Removal: A Detailed Breakdown
Accurate coding is crucial for reimbursement. Below are key CPT codes for hardware removal:
| CPT Code | Description |
|---|---|
| 20670 | Removal of implant; superficial (e.g., buried wire, pin, or rod) |
| 20680 | Removal of implant; deep (e.g., buried wire, pin, screw, metal band, nail, rod, or plate) |
| 20690 | Application of a uniplane external fixation system (for complex removals requiring stabilization) |
Note: Modifiers may be required if hardware removal is performed during a separate encounter from the initial procedure.
6. Preoperative Evaluation and Patient Preparation
Before hardware removal, a thorough evaluation is necessary:
-
Imaging (X-rays, CT scans to assess hardware position and bone healing)
-
Infection workup (CRP, ESR, cultures if infection is suspected)
-
Patient counseling (risks, benefits, and expected recovery)
7. Surgical Techniques for Hardware Removal
The procedure varies based on hardware type:
-
Open Approach – Incision over the implant site, dissection to expose hardware.
-
Minimally Invasive Techniques – Smaller incisions for screw or pin removal.
-
Specialized Tools – Screw extractors, trephines for broken screws.
8. Postoperative Care and Complications
-
Pain management (NSAIDs, ice, elevation)
-
Infection monitoring (antibiotics if needed)
-
Physical therapy (if joint stiffness occurs)
Potential Complications:
-
Infection
-
Nerve injury
-
Fracture at screw holes
9. Billing and Coding Guidelines
-
Document medical necessity (pain, infection, or mechanical issue).
-
Use correct CPT and ICD-10 codes (e.g., Z47.2 for aftercare following orthopedic surgery).
-
Append modifiers (e.g., -58 for staged procedures).
10. Insurance Considerations and Reimbursement Challenges
-
Prior authorization may be required.
-
Medicare and private insurers have varying policies on elective hardware removal.
11. Case Studies and Clinical Scenarios
Case 1:
A 35-year-old male with persistent tibial pain due to a prominent plate.
-
Procedure: Deep hardware removal (CPT 20680)
-
Outcome: Symptom relief at 6-week follow-up.
12. FAQs on CPT Code for Hardware Removal
Q1: When is hardware removal medically necessary?
A: When there is pain, infection, or hardware failure.
Q2: What is the recovery time after hardware removal?
A: Typically 2-6 weeks, depending on the site.
Q3: Can hardware removal be denied by insurance?
A: Yes, if deemed elective without sufficient documentation.
13. Conclusion
Hardware removal is a common orthopedic procedure with specific CPT coding and billing requirements. Proper documentation, correct coding, and understanding insurance policies are essential for successful reimbursement. Surgeons and coders must collaborate to ensure compliance and optimal patient care.
