Summary & Overview
CPT 01682: Anesthesia for Total Knee Arthroplasty
CPT code 01682 designates anesthesia services provided for total knee arthroplasty (TKA). As TKA remains one of the most common major joint replacement procedures, this code captures anesthetic care associated with a high-volume surgical service that has significant implications for perioperative resource use, billing workflows, and payment policies nationwide.
Key payers examined in this publication include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for anesthesia in TKA, typical settings of care, and commonly associated diagnosis presentations. The analysis highlights how CPT code 01682 interfaces with surgical procedural codes for TKA and with common perioperative billing practices.
The publication provides benchmarks for utilization and payment where available, notes recent policy or coverage considerations impacting anesthesia billing for knee arthroplasty, and summarizes coding relationships that affect claims submission and payer adjudication. Intended for clinicians, billing specialists, and policy analysts, the content clarifies what CPT code 01682 represents, its relevance to surgical and anesthesiology service lines, and the practical coding elements to consider when documenting anesthetic services for total knee arthroplasty.

Clinical & Coding Specifications
Clinical Context
A 68-year-old ambulatory patient with end-stage knee pain from unilateral primary osteoarthritis presents for elective total knee arthroplasty. Pre-operative evaluation by anesthesia includes review of medical history (hypertension, well-controlled type 2 diabetes, prior right knee arthroplasty noted by presence of right artificial knee joint), airway assessment, medication reconciliation, and informed anesthesia planning. On the day of surgery the patient is taken to an operating room in an inpatient or outpatient surgical facility. Anesthesia care for total knee arthroplasty (01682) is provided by an anesthesiologist or certified registered nurse anesthetist and typically involves neuraxial anesthesia (spinal or combined spinal-epidural) with monitored sedation, or general endotracheal anesthesia when neuraxial techniques are contraindicated or patient preference dictates. Perioperative management includes intravenous access, standard ASA monitors, antibiotic prophylaxis coordination, intraoperative analgesia and multimodal pain strategies, and postoperative handoff to PACU with plan for regional analgesia (e.g., peripheral nerve block) or systemic opioids as indicated. Typical sites of service are inpatient hospital operating room or ambulatory surgery center performing total knee arthroplasty. Common clinical indications include M17.10, M17.11, M17.12, and M17.5, with occasional presence of an existing prosthesis (Z96.651) influencing surgical and anesthesia planning.
