(Active) Effective Date: N/A Anesthesia - Head Anesthesia Feed
Anesthesia for procedures on salivary glands, including biopsy.
Modifiers are applicable (e.g., P1-P6, 23, 53, 76, 77, 99, AA, AD, CR, G8, etc.) to indicate specific circumstances or services.
Medical necessity for anesthesia is determined by the nature of the salivary gland procedure and the patient's overall health. Anesthesia is medically necessary when the procedure requires the patient to be unconscious or sedated for pain management, immobility, or safety.
The anesthesiologist performs a pre-operative evaluation, induces anesthesia, monitors the patient throughout the procedure performed by another provider, documents medications, monitors vital signs and responses, records anesthesia times, and oversees the patient's transfer to post-anesthesia care.They are responsible for managing the patient's comfort and safety related to the anesthesia.
In simple words: The anesthesiologist provides all the care needed to make you comfortable and safe during a procedure on your salivary glands, which includes a pre-operative evaluation, administering and monitoring the anesthesia during the procedure, and managing your immediate post-operative care until you're ready for the recovery room.
Anesthesia services for a patient undergoing a procedure on the salivary glands, including biopsy.Includes pre- and post-operative evaluation, inducing the patient, monitoring during the procedure (performed by another provider), documentation of medications, monitoring methods, patient responses, anesthesia start/stop times, and overseeing transfer to post-anesthesia care.This code covers standard monitoring (ECG, temperature, blood pressure, oximetry, capnography, mass spectrometry).It does not include unusual monitoring (Swan-Ganz catheters, intra-arterial lines, central venous lines), which can be coded separately with proper documentation.
Example 1: A patient undergoes a biopsy of the parotid gland. The anesthesiologist administers general anesthesia, monitors the patient's vital signs throughout the procedure, and manages post-operative pain., A patient has a submandibular gland excision. The anesthesiologist provides monitored anesthesia care (MAC) and manages the patient's airway and vital signs during the procedure., A patient with a suspected salivary gland stone requires sialendoscopy. The anesthesiologist administers local anesthesia with sedation and monitors the patient during the procedure.
Documentation should include pre-anesthesia evaluation, type and amount of anesthesia administered, monitoring methods and results, patient responses, anesthesia start and stop times, and post-anesthesia notes.
** Anesthesia time is calculated from when the anesthesiologist prepares the patient in the operating/procedure room until responsibility for post-operative care is transferred to another provider. Time units are calculated based on payer guidelines (e.g., 15-minute increments).For multiple anesthesia services during the same encounter, bill the most complex code with the highest base unit value and the total combined anesthesia time.
