Many patients have anesthesia billing questions.  Anesthesia billing is calculated differently than other specialties and in most cases is far more complex.  Anesthesia services are calculated based on the following criteria: difficulty of the procedure, time, and other modifying factors such as, the health of the patient. Calculating anesthesia charges may also includes a cost specific to a particular location.

The general formula for calculating anesthesia charges is as follows:

(Base units + Time units + Modifying units) x Conversion factor = Anesthesia charge

Base Units = Each anesthesia procedure has an assigned code and each code has a base unit value. The base unit value is reflective of the difficulty and skill required for the procedure. The higher the difficulty, the higher the base units will be. Base units are constant and do not change.

Time Units = Each anesthesia procedure takes a certain amount of time. Time is typically 15 minutes in length, but may be 10-12 minutes depending on the location. If an anesthesia procedure takes 45 minutes, using a 15-minute time unit, this would equal 3 time units to be included in the anesthesia calculation formula.

Modifying Unit = A modifying unit accounts for special conditions that affect the anesthesia plan and procedure. Modifying factors may include a patient’s physical health or emergency situations.

Conversion Factor = This is cost that has been assigned to each unit and are specific to the location of the anesthesia provider/administrator. This cost will vary across the United States.

Total Anesthesia Charge = Once you have added the total number of units together it is multiplied by the conversion factor and the total anesthesia charge is calculated.

Anesthesiologists and CRNAs are not always employed by the medical facility where the patient received anesthesia care.  Your billing statement for anesthesia services will arrive separately from the hospital or other medical facility bill where your surgery or procedure took place.  It is also possible to have a surgery or procedure take place at an in-network medical facility, but have an anesthesia provider that is not in-network with your insurance provider.  This is an important anesthesia billing question to ask prior to your surgery or procedure so you can plan ahead and know what to expect.  Click here to learn more about anesthesia.
