AAPC - American Academy of Professional Coders Anesthesia Coding and Modifiers Questions and Answers

Question 1

A 72-year-old patient with severe systemic disease undergoes a complex surgical procedure under general anesthesia. The anesthesiologist personally performs the entire anesthesia service. Which combination of modifiers should be appended to the anesthesia CPT code?

Accepted Answer

P4, AA

Answer

The Physical Status Modifier P4 is used for a patient with severe systemic disease that is a constant threat to life. The HCPCS Level II modifier AA is used to indicate that the anesthesia service was personally performed by the anesthesiologist. P1 is for a normal healthy patient, P2 is for mild systemic disease, and P3 is for severe systemic disease without a constant threat to life. QK is for medical direction of 2-4 concurrent procedures, and QZ is for a CRNA service without medical direction.

Question 2

A patient undergoes a surgical procedure where multiple anesthesia codes could potentially apply. According to AAPC guidelines, how should the coder report the anesthesia service?

Accepted Answer

Report the anesthesia code for the most complex procedure with the highest base unit value.

Answer

When multiple surgical procedures are performed during a single anesthetic administration, only the anesthesia code for the most complex procedure is reported. The complexity is determined by the base unit value assigned to the anesthesia code; the code with the highest base unit value should be used. The total time for all procedures is then reported with that single anesthesia code.

Question 3

Which of the following is a 'Qualifying Circumstance' add-on code used in anesthesia coding?

Accepted Answer

99140

Answer

CPT code 99140 represents 'Anesthesia complicated by emergency conditions' and is an add-on code used to report qualifying circumstances. 01999 is the CPT code for an unlisted anesthesia procedure. P5 is a Physical Status Modifier for a moribund patient. G8 is a HCPCS modifier for MAC on a deep, complex, or invasive procedure.

Question 4

An anesthesiologist is medically directing one CRNA for an anesthesia case. Which HCPCS Level II modifier should be appended to the anesthesiologist's claim?

Accepted Answer

QY

Answer

Modifier QY is used to indicate the medical direction of one certified registered nurse anesthetist (CRNA) by an anesthesiologist. Modifier QX is used by the CRNA to report the service with medical direction. QZ is used by the CRNA when no medical direction is provided. QK is for medical direction of two, three, or four concurrent anesthesia procedures.

Question 5

A healthy 45-year-old patient undergoes anesthesia for a procedure on their lower abdomen. The CPT code for the surgical procedure crosswalks to anesthesia CPT code 00840. What is the correct Physical Status Modifier to append?

Accepted Answer

P1

Answer

The Physical Status Modifier P1 is used to describe a normal, healthy patient. Since the scenario describes the patient as 'healthy,' P1 is the appropriate modifier. P2 is for a patient with mild systemic disease, P3 for severe systemic disease, and P4 for severe systemic disease that is a constant threat to life.
