Summary & Overview
CPT 20694: Removal of External Fixation System Under Anesthesia
CPT code 20694 covers the surgical removal of an external fixation system performed while the patient is under anesthesia. This code is used when an external fixator and any associated implants are removed after the treated skeletal defect has sufficiently healed. The code is significant nationally because external fixation is a common technique in fracture care and limb reconstruction; accurate coding affects facility and professional billing, claims adjudication, and longitudinal tracking of orthopedic procedures.
Key payers referenced in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for use of the code, typical settings for service delivery (operating room or procedure suite with anesthesia), and common billing considerations tied to payer coverage. The publication summarizes benchmarks and policy-relevant topics that affect reimbursement and utilization for device removal procedures, and clarifies where input data are available or absent.
Intended readers include coding professionals, practice managers, orthopedic surgeons, and payer policy analysts seeking a national perspective on how CPT code 20694 is applied and reimbursed. Data not available in the input are explicitly noted in accompanying sections.
Billing Code Overview
CPT code 20694 describes the removal of an external fixation system while the patient is under anesthesia. An external fixation system (external fixator, ex fix) is a skeletal fixation device that stabilizes and maintains alignment of bony structures with hardware that remains outside the body while pins or wires traverse bone. The procedure removes the external fixation components and any associated implants once healing is sufficient.
-
Service type: Surgical removal of external skeletal fixation device performed under anesthesia
-
Typical site of service: Operating room or procedure suite where the patient can receive anesthesia
Clinical & Coding Specifications
Clinical Context
A 42-year-old male with a comminuted distal tibia fracture underwent initial stabilization with an external fixation system in the emergency department to maintain alignment and permit soft-tissue recovery. After serial radiographs and clinical assessment over 6–8 weeks demonstrate sufficient bony healing and stable alignment, the patient returns to the operating room for planned removal of the external fixator under general anesthesia. The typical workflow includes preoperative assessment and informed consent, verification of radiographic union and absence of infection at pin sites, anesthesia induction, sterile preparation of the limb, sequential removal of external fixation pins and connecting rods, inspection of pin tracts, hemostasis and dressing of pin sites, and post-anesthesia recovery with wound care instructions and follow-up arrangements. Typical site of service is an ambulatory surgical center or hospital operating room. The service type is operative/invasive removal of an external skeletal fixation device performed under anesthesia.
Coding Specifications

|---|---|---|
26 | Professional component | Use when reporting only the professional (physician) portion distinct from the technical component, if applicable for global service split arrangements. |
52 | Reduced services | Use when the procedure was partially reduced or not completed as originally planned. |
53 | Discontinued procedure | Use when the removal is started but halted due to an intraoperative complication or patient safety concern. |
76 | Data not available in the input. | Data not available in the input. |
78 | Return to OR for a related procedure during the postoperative period | Use when the patient returns to the operating room for a related procedure under the global period. |
79 | Unrelated procedure or service by the same physician during the postoperative period | Use when an unrelated operative procedure is performed during the global period. |
RT | Right side | Use to indicate the procedure site is the right limb when laterality is required. |
LT | Left side | Use to indicate the procedure site is the left limb when laterality is required. |
50 | Bilateral procedure | Use if fixation and removal were performed bilaterally and payer requires bilateral reporting. |
22 | Increased procedural services | Use when the removal required substantially greater work or complexity than typical (document rationale). |
23 | Unusual anesthesia | Use when significant, medically necessary anesthesia is provided in unusual circumstances outside normal sedation. |
24 | Data not available in the input. | Data not available in the input. |
