Which CPT code range is designated for anesthesia services?
00100-01999
10000-19999
20000-29999
50000-59999
Anesthesia services are coded within the CPT range 00100 - 01999. Other ranges cover surgery, radiology, and other specialties, not anesthesia.
In anesthesia coding, what do base units represent?
The total minutes of anesthesia time
Complexity and skill level of the service
Cost of drugs and supplies used
Patient's physical status
Base units reflect the inherent complexity and skill required for the anesthesia service. Time units and modifiers account for duration and patient factors separately.
Which modifier indicates anesthesia services personally performed by the anesthesiologist?
AA
QX
QK
QZ
Modifier AA is used when the anesthesiologist personally performs the entire anesthesia service. Other Q modifiers denote various types of medical direction or supervision.
Anesthesia time begins when the anesthesiologist starts care and ends when the patient has been:
Given the first incision
Transferred to recovery or post-anesthesia care
Positioned on the operating table
Taken to the pre-op holding area
Anesthesia time is counted from the start of anesthesia care through the transfer of the patient to recovery. It does not begin or end at incision or positioning times.
What does the Physical Status modifier P1 indicate?
Healthy patient with no systemic disease
Patient with mild systemic disease
Patient with severe systemic disease
Patient declared brain dead
Modifier P1 is assigned to a healthy patient with no underlying systemic disease. Other P modifiers reflect increasing levels of systemic disease or special conditions.
How many time units are assigned for an anesthesia duration of 75 minutes?
5
4
3
6
Time units are calculated in 15-minute increments. Seventy-five minutes equals five 15-minute units (75 ÷ 15 = 5).
For a procedure with 4 base units and 60 minutes of anesthesia time, what is the total unit count?
8
7
9
10
Time units for 60 minutes equal 4 (60 ÷ 15). Adding the 4 base units yields a total of 8 anesthesia units.
Which modifier signals that the anesthesiologist medically directed a CRNA over 2 - 4 concurrent cases?
QY
QZ
QK
AA
Modifier QK indicates medical direction of 2 - 4 concurrent cases by an anesthesiologist. QY and QZ denote other directions or solo CRNA services.
Which modifier is used when a CRNA administers anesthesia without physician supervision?
QK
QY
QZ
AA
Modifier QZ denotes anesthesia services provided by a CRNA without physician involvement. Other modifiers describe physician direction or personal performance.
Monitored Anesthesia Care (MAC) should be reported with which modifier?
QS
AD
QX
AA
Modifier QS is applied to indicate Monitored Anesthesia Care services. Other modifiers reflect supervision status or personal performance.
Which documentation piece is specifically required prior to anesthesia services?
Pre-anesthetic evaluation
Operative report
Postoperative note
Discharge summary
A pre-anesthetic evaluation documents the anesthesiologist's assessment, plan, and informed consent. Operative and post-op notes address surgical, not anesthesia, care.
When a surgeon administers local anesthesia infiltration, how should anesthesia services be reported?
Not reported separately (bundled)
Billed by the surgeon as an anesthesia service
Reported with modifier AA
Reported with modifier QX
Local infiltration by a surgeon is considered integral to the surgical procedure and is bundled, so no separate anesthesia code is reported.
What does Physical Status modifier P3 indicate?
Mild systemic disease
Severe systemic disease
Brain death
Moribund patient
Modifier P3 is used for patients with severe systemic disease. P2 is mild disease, while higher modifiers denote more critical conditions.
Which CPT code is used for anesthesia services provided in emergency situations?
99140
99100
99240
99000
CPT code 99140 is the add-on code specifically for anesthesia services provided for emergency procedures. Other codes cover different services or settings.
All of the following are required times for anesthesia documentation EXCEPT:
Anesthesia start time
Anesthesia end time
Operative incision time
Emergence time
Anesthesia records must include start, end, and emergence times. Incision time pertains to the surgeon's report and is not part of anesthesia time documentation.
When two separate anesthesia procedures with different base units occur in one session, how should coding be handled?
Report both codes separately
Report the procedure with the higher base units plus the add-on code for the second
Sum both base units and report one code
Report only the second procedure
When multiple anesthesia procedures are performed, you report the code with the highest base units and then the appropriate add-on code for the additional procedure. You do not sum separate base units or omit the first procedure.
In a teaching hospital, which modifier indicates anesthesia services provided by a resident under the general supervision of an attending physician?
G8
GC
GE
G9
Modifier GC is used for services performed by a resident under the general supervision of a teaching physician. Other G modifiers indicate other teaching scenarios or conditions.
Anesthesia for cardiac catheterization has 7 base units and lasts 120 minutes. What are the total units billed?
14
16
15
13
Time units are calculated as 120 ÷ 15 = 8. Adding the 7 base units yields 15 total anesthesia units.
If the anesthesia start time is recorded incorrectly, what is the most significant coding consequence?
Claim denial for the anesthetic procedure
Increased audit exposure and potential recoupment
Automatic approval of higher payment
No impact if the end time is correct
Inaccurate start times can lead to audit exposure and potential payment recoupment because time units drive anesthesia reimbursement. Insurers often scrutinize time documentation carefully.
Which nerve block is reportable separately from anesthesia services as an add-on code?
Superficial local infiltration
Interscalene brachial plexus block
Topical anesthesia
Surgeon's digital block
Interscalene brachial plexus block is a deep peripheral nerve block reported with its own add-on CPT code. Superficial infiltration and surgeon digital blocks are considered integral to the procedure.
