CPT 01486: Anesthesia for Total Ankle Replacement
CPT code 01486 represents anesthesia services furnished for a total ankle replacement (total ankle arthroplasty). This code identifies perioperative anesthetic management for a major lower-extremity orthopedic procedure and is used across hospital operating rooms and ambulatory surgical centers. Nationally, accurate use of this code supports appropriate payment for anesthesiology teams involved in complex joint reconstruction and contributes to quality tracking of anesthesia resource use for lower-extremity arthroplasty.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise overview of clinical context for anesthesia on total ankle replacement, common related procedure and diagnosis linkages, and the payer landscape relevant to claims processing. The publication outlines typical sites of service, associated procedure groupings, and the common modifiers and reporting considerations that appear on billing lines tied to this service. It also cross-references related anesthesia CPT codes for adjacent lower-leg, ankle, and foot procedures to aid clinical coders and billing staff in selecting the most appropriate anesthesia code for various operative approaches. The content is aimed at national stakeholders involved in coding, revenue cycle, and clinical operations who need a clear summary of what CPT code 01486 signifies and how it fits into broader orthopedic anesthesia coding practice.

Billing Code Overview
CPT code 01486 describes anesthesia services provided for a total ankle replacement. The service type is anesthesia for major orthopedic surgery of the ankle (total ankle arthroplasty). The typical site of service is an operating room or ambulatory surgical center where total ankle replacement procedures are performed.
Clinical & Coding Specifications
Clinical Context
A 62-year-old male with end-stage ankle osteoarthritis scheduled for a total ankle replacement presents for preoperative assessment. He reports progressive bilateral ankle pain and limited mobility; imaging and prior consultations confirm joint degeneration. Relevant diagnoses include chronic ankle pain and prior tibial fracture status. The anesthesia team reviews medical history, medications, and airway status, obtains informed consent for anesthesia, and coordinates perioperative planning with orthopedic surgery and postoperative pain management. On the day of surgery the patient arrives to an ambulatory surgical or inpatient orthopedic operating room suite. Monitors are placed (ECG, pulse oximetry, blood pressure, end-tidal CO2), intravenous access is established, and anesthesia is induced according to patient factors and planned surgical duration. Anesthesia technique is typically general endotracheal anesthesia or neuraxial/regional block (popliteal/sciatic ± saphenous nerve block) supplemented by sedation as appropriate. Intraoperative management includes positioning with attention to the operative lower extremity, maintenance of hemodynamic stability, antibiotic prophylaxis timing, and management of blood loss. Postoperative handoff to PACU or inpatient recovery includes pain control plan (regional catheter, systemic analgesics), assessment for complications, and documentation of anesthesia start and stop times for billing of 01486 (anesthesia for total ankle replacement). Documentation includes anesthetic technique, monitoring, airway management, invasives if used, intraoperative events, and any modifier-applicable circumstances (e.g., unusual procedural difficulty, bilateral procedures, or split/shared anesthesia).
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia involves substantially greater work or complexity than typical for the service, documented and justified. |
23 | Unusual anesthesia | Use when general anesthesia is medically necessary for procedures normally done without it (rare for this code). |
50 | Bilateral procedure | Use when total ankle replacements are performed simultaneously on both ankles. |
52 | Reduced services | Use when the anesthesia service is partially reduced or not performed to its full extent. |
53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances after anesthesia has been initiated. |
54 | Surgical care only | Use when the reporting practitioner provided only the surgical portion of care (not typical for anesthesia reporting; included when applicable to other clinicians). |
55 | Postoperative management only | Use when the anesthesia practitioner provides only postoperative pain management and not intraoperative care. |
62 | Two surgeons/dual operator | Use when two qualified surgeons operate together and anesthesia billing must reflect the complexity of coordination (rarely affects anesthesia coding but may be reported). |
78 | Unplanned return to the operating room following surgery | Use when the patient returns to OR for related procedure during the global period and additional anesthesia is provided. |
AA | Anesthesia services performed personally by anesthesiologist | Use when the anesthesiologist personally performs the anesthetic. |
AD | Medical supervision by anesthesiologist supervising certified registered nurse anesthetists (CRNAs) | Use when anesthesia is personally performed by a CRNA under direct supervision per payer rules. |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for anesthesia | Use when a qualified non-physician provides the anesthesia service as allowed by payer. |
QK | Medical direction of two, three, or four CRNAs | Use when the anesthesiologist medically directs multiple CRNAs during the anesthetic. |
QS | Monitored anesthesia care service | Use when monitored anesthesia care (MAC) is provided instead of general or regional anesthesia. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
207L00000X | Anesthesiology | Primary specialty for delivery of perioperative anesthesia services. |
207LA0401X | Pain Medicine (Anesthesiology) | Relevant for perioperative and postoperative pain management, regional anesthesia techniques. |
207LP2900X | Pediatric Anesthesiology | Applicable when the procedure is performed in pediatric patients requiring specialized anesthesia care. |
Related Diagnoses
| ICD-10 Code | Description | Clinical Relevance |
|---|---|---|
S82.101A | Fracture of upper end of right tibia, initial encounter for closed fracture | Prior or recent tibial fracture may necessitate ankle reconstruction or complicate total ankle replacement planning. |
S82.102A | Fracture of upper end of left tibia, initial encounter for closed fracture | Same relevance for the left side; bilateral tibial injuries can influence anesthesia and surgical approach. |
M25.571 | Pain in right ankle and joints of right foot | Symptom commonly leading to evaluation and surgical intervention such as total ankle replacement. |
M25.572 | Pain in left ankle and joints of left foot | Left-sided ankle pain relevant when planning unilateral or bilateral replacement. |
S93.401A | Sprain of unspecified ligament of right ankle, initial encounter | Ligamentous injury may contribute to joint instability and degeneration that leads to arthroplasty. |
Related CPT Codes
| CPT Code | Description | Relationship to This Procedure |
|---|---|---|
01480 | Anesthesia for open procedures on bones of lower leg, ankle, and foot; tibia and fibula | Alternative anesthesia code when the surgical procedure primarily involves the tibia or fibula rather than total ankle replacement. |
01482 | Anesthesia for open procedures on bones of lower leg, ankle, and foot; ankle joint | Closely related; used for anesthesia when the service is specifically for ankle joint open procedures and may be selected based on operative scope. |
01484 | Anesthesia for open procedures on bones of lower leg, ankle, and foot; foot | Related when the surgical field extends into the foot or when procedures on foot structures accompany the ankle replacement. |
20680 | Removal of implant; deep (e.g., buried wire, pin, screw, metal band, nail, rod or plate) | May be performed prior to or during total ankle replacement if prior hardware requires removal; impacts anesthesia planning and duration. |
