CPC Chapter 16- Anesthesia Review Flashcards
Procedures commonly carried out in addition to the primary procedure performed. Codes may not be reported alone and are identified with a + sign
Add-on Codes
Begins when the anesthesiologist begins to prepare the patient for the induction of anesthesia and ends when the anesthesiologist is no longer in personal attendance
Anesthesia Time
A catheter inserted into an artery. It is used most commonly to measure real-time blood pressure and to obtain samples for arterial blood gas
Arterial Line
Value assigned to anesthesia codes for anesthetic management of surgery and diagnostic tests. will vary depending on the difficulty of the surgery or dignostic tests, and the management of anesthesia
Base Line Value
A technique used to take over temporarily the function of the heart and lungs
Cardiopulmonary Bypass (CPB)
A catheter placed in a large vein such as the internal jugular, subclavian, or femoral vein with the tip of the catheter close to the atrium, or in the right atrium of the heart
Central Venous Catheter
Technique used in general anesthesia to reduce blood pressure to control bleeding during surgery. Watch anesthesia record for notes regarding deliberate or controlled hypotension
Controlled Hypotension
A unit multiplier used to convert anesthesia units into a dollar amount for anesthesia services. Are reviewed annually boy CMS and vary geographically. Also may be negotiated with insurance companies
Conversion Factor
Direct measurement of the blood pressure in the right atrium and vena cava. Reflets the amount of blood returning to the heart and the ability of the heart to pump the blood from the right heart into the pulmonary system
Central Venous Pressure (CVP)
Based on the physician fee schedule. Payments are made under the Relative Value Unit, rather than by Conversion Factor. Time is not a consideration for payment. Examples are arterial lines, CV line, emergency intubation, and Swan-Ganz catheter insertion
Flat Fee
Implies a temperature of 20 degrees centigrade or less
Hypothermic Circulatory Arrest
Occurs when an anesthesiologist is involved in two, three, or four concurrent anesthesia procedures, or a single anesthesia procedure with a qualified anesthetist. CMS and other carriers publish criteria to be met to report medical direction
Medical Direction
Occurs when an anesthesiologist is involved in five or more concurrent anesthesia procedures or fails to meet required medical direction criteria
Medical Supervision
Refers to a technique for many surgical procedures that do not require deep sedation or general anesthetic. Anesthesia provider must be prepared to convert to general anesthesia, if necessary
Monitored Anesthesia Care (MAC)
A flow directed catheter inserted into the pulmonary artery. Are used to measure pressures and flows within the cardiovascular system
Pulmonary Artery Catheter (for example, Swan-Gans) (PAC)
Modifier used to report the physical status assigned to each patient undergoing anesthesia. Patients are ranked by their individual health status. The anesthesia provider must assign the physical status
Physical Status Modifier
Term used when a cardiopulmonary bypass (CPB) machine is used to function as the heart and lungs during heart surgery
Pump Oxygenator
Circumstances significantly affecting the character of an anesthesia service. These add-on procedures may be reported only with anesthesia codes. More than one may be reported, if applicable. May not be reported separately when a code descriptor already indicates the circumstance. Do not use modifiers for Medicare Beneficiaries
Qualifying Circumstances
A unit measure used to assign a value to services. It is determined by assigning weight to factors such as physician work, practice expense and malpractice expense
Relative Value Unit
