(Active) Effective Date: N/A Revision Date: N/A Anesthesia - Anesthesia for Procedures on the Knee and Popliteal Area Anesthesia Feed
Anesthesia for open or arthroscopic total knee arthroplasty.
Modifiers may apply depending on the specific circumstances of the anesthesia services rendered (e.g., unusual anesthesia, discontinued procedure, repeat procedure). Refer to CPT guidelines for specific modifier use and billing considerations.
Medical necessity is established by the need for anesthesia services during a total knee arthroplasty to ensure patient safety, comfort, and effective surgical management. This would include considerations for the patient's overall health status and surgical complexity.
Preoperative evaluation, induction and maintenance of anesthesia, monitoring vital signs and administering medications, post-operative care oversight.
In simple words: This code covers the services of an anesthesiologist during a total knee replacement surgery (whether open or arthroscopic).The anesthesiologist prepares the patient, puts them to sleep or numbs them, monitors them during the surgery, and helps them recover afterward.
This CPT code encompasses anesthesia services rendered during an open or arthroscopic total knee arthroplasty.The anesthesia provider's responsibilities include preoperative patient evaluation, induction of anesthesia, monitoring throughout the procedure (including recording medication administration, monitoring methods, patient responses, and anesthesia start/stop times), and overseeing patient transfer to post-anesthesia care. Standard monitoring (ECG, temperature, blood pressure, oximetry, capnography, and mass spectrometry) is included; however, unusual monitoring (Swan-Ganz catheters, intraarterial lines, or central venous lines) requires separate coding with sufficient documentation.
Example 1: A 65-year-old female patient undergoing a total knee arthroplasty under general anesthesia. The anesthesiologist performs a pre-operative assessment, administers general anesthesia, monitors the patient throughout the procedure, manages any complications, and oversees the post-operative transfer., A 72-year-old male patient with a history of hypertension undergoing a total knee arthroplasty under spinal anesthesia.The anesthesiologist performs a pre-operative assessment considering the patient's hypertension, administers spinal anesthesia, carefully monitors vital signs, and manages any potential complications., A 50-year-old female patient undergoing an arthroscopic total knee repair.The anesthesiologist provides monitored anesthesia care (MAC), administering local anesthesia and sedation, closely monitoring vital signs, and responding to any changes in the patient's condition during the procedure.
Pre-operative anesthesia evaluation, anesthesia record detailing medications administered, monitoring techniques employed, patient responses, and anesthesia start and stop times, post-anesthesia care notes.
** The selection of anesthesia type (general, regional, or MAC) depends on patient factors and surgeon preference.This code represents the anesthesia services, not the surgical procedure itself.
