Summary & Overview
CPT 01214: Anesthesia for Open Total Hip Arthroplasty
CPT code 01214 denotes anesthesia services for open total hip arthroplasty, a common major orthopedic procedure. This code is used nationally to classify perioperative anesthetic care for patients undergoing total hip replacement via an open surgical approach, capturing the complexity and resource intensity of anesthesia for major joint reconstruction. Accurate use of this code affects clinical documentation, facility billing, and payer adjudication for high-acuity surgical anesthesia services.
Key payers in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise explanation of the code’s clinical context and service setting, guidance on common billing considerations, and comparisons to related procedural coding such as the hip arthroplasty surgical code. The publication also outlines typical payer coverage patterns and coding relationships relevant to anesthesia professionals, perioperative teams, and billing staff.
This summary provides national-level context for clinicians and administrators seeking clarity on the purpose of CPT code 01214, how it aligns with surgical service lines, and what elements of care it represents for anesthesia practice in major orthopedic procedures.
Billing Code Overview
CPT code 01214 describes anesthesia services provided for a patient undergoing an open total hip arthroplasty. The service type is anesthesia for major orthopedic surgery. The typical site of service is an inpatient or ambulatory surgical setting where open total hip arthroplasty (arthroplasty of the hip) is performed.
Clinical & Coding Specifications
Clinical Context
A 68-year-old male with advanced osteoarthritis presents for an open total hip arthroplasty. The preoperative assessment by the anesthesia team documents controlled hypertension, type 2 diabetes, and prior right knee arthroplasty. The patient is evaluated in preop clinic by an anesthesiologist or certified registered nurse anesthetist (CRNA) using airway assessment, review of medications, and perioperative risk stratification (ASA physical status P3). On the day of surgery, regional anesthesia (spinal or neuraxial) with sedation or general endotracheal anesthesia is administered depending on surgical and patient factors. Intraoperative anesthetic management includes airway management, invasive and noninvasive monitoring, fluid management, hemodynamic support, blood loss management, and postoperative analgesia planning (nerve block, multimodal analgesia). Postoperative handoff is provided to PACU staff with instructions for pain control, anticoagulation timing, and mobilization. Documentation includes the anesthesia start and end times, type of anesthesia, monitored parameters, medications administered, any anesthetic complications, and modifiers as applicable for unusual circumstances (for example, additional complexity, multiple anesthetists, or assistant involvement).
