Code 00300 covers neck procedures; 00400 covers thorax surface procedures; 00500 covers intrathoracic procedures. Repair of the palate — a structure in the oral cavity — is correctly placed in the head (00100) anesthesia range.

Question 6

A patient with well-controlled hypertension and mild asthma — both stable with no functional limitations — presents for elective surgery. Which physical status modifier applies?

  1. P1
  2. P3
  3. P4
  4. P2 (correct answer)
Explanation: Physical status modifier P2 designates a patient with mild systemic disease. Well-controlled hypertension and mild asthma represent mild systemic conditions without functional limitation. P1 is for a normal, healthy patient with no systemic disease; P3 is for severe systemic disease. The combination of two mild, well-controlled conditions places this patient in the P2 category.

Question 7

A patient requires anesthesia for a diagnostic lumbar puncture (spinal tap) for cerebrospinal fluid analysis. Which CPT® anesthesia code covers this procedure?

  1. 00630
  2. 00635 (correct answer)
  3. 00640
  4. 00670

  4. 01470-01522
Explanation: CPT® anesthesia codes 01810-01860 cover procedures on the forearm, wrist, and hand. Code 01830 covers open wrist procedures; 01820 covers closed treatment of distal radial fracture. The upper arm and elbow range (01710-01782) and lower leg range (01300-01444) cover different regions. The distal radius at the wrist falls in the forearm, wrist, and hand range (01810-01860).

Question 9

A patient requires anesthesia for a diagnostic bronchoscopy. Which CPT® anesthesia code range covers intrathoracic procedures?

  1. 00400-00474
  2. 00600-00670
  3. 00500-00580 (correct answer)
  4. 00700-00797
Explanation: CPT® anesthesia codes 00500-00580 cover intrathoracic procedures, including bronchoscopy. The specific code for bronchoscopy anesthesia falls within this range — for example, 00520 covers anesthesia for closed chest procedures not otherwise specified, which includes diagnostic bronchoscopy. The thorax surface codes (00400-00474) cover chest wall and breast procedures, not intrathoracic airways. The 00600-00670 range covers spine and spinal cord procedures.

Question 10

A patient requires anesthesia for a cardiac catheterization performed in an interventional suite. Which CPT® anesthesia code range covers radiological and cardiovascular imaging procedures?

Explanation: CPT® anesthesia codes 01958-01969 cover obstetric procedures. Code 01961 covers cesarean delivery; 01960 covers vaginal delivery; 01968 covers neuraxial labor analgesia with conversion to cesarean. All obstetric anesthesia codes are in the 01958-01969 range, separate from the lower abdominal (00800) and perineal (00902) ranges.

Question 12

A patient requires anesthesia for a total thyroidectomy. Which CPT® anesthesia code covers thyroid surgery?

  1. 00300
  2. 00320 (correct answer)
  3. 00322
  4. 00350
Explanation: CPT® 00320 covers anesthesia for procedures on the esophagus, thyroid, larynx, trachea, and lymphatic system of the neck, not otherwise specified (age 1 year or older). A total thyroidectomy falls within this category. Code 00322 is specifically for needle biopsy of the thyroid — not for open thyroid surgery. Code 00300 covers integument, muscles, and nerves of the head and neck not otherwise specified; 00350 covers major vessels of the neck.

Question 13

A patient undergoes anesthesia for a total knee replacement (TKR). Which CPT® anesthesia code is reported?

  1. 01380
  2. 01400
  3. 01402 (correct answer)
  4. 01404
Explanation: CPT® 01402 covers anesthesia for total knee replacement. Code 01380 covers cast application; 01400 covers open or surgical arthroscopic knee procedures other than total replacement; 01404 covers disarticulation at the knee. Total knee arthroplasty has a specific code (01402) that distinguishes it from other open knee procedures.

Question 14

A patient undergoes anesthesia for a transurethral resection of the prostate (TURP). Which CPT® anesthesia code is reported?

  1. 00830
  2. 00840
  3. 00914 (correct answer)
  4. 00920
Explanation: CPT® 00914 covers anesthesia for TURP and is found in the 00902-00952 perineal range. Code 00830 covers herniorrhaphy (lower abdomen); 00840 covers other intraperitoneal lower abdominal procedures; 00920 covers procedures on the male external genitalia. TURP uses a transurethral approach to the prostate, placing it in the perineal section with code 00914.

Question 15

Anesthesia is provided for burn excision of a wound covering 6% of total body surface area (TBSA). Which CPT® anesthesia code covers burn procedures involving between 4% and 9% TBSA?

  1. 01952 (correct answer)
  2. 01951
  3. 01953
  4. 01958
Explanation: CPT® 01952 covers anesthesia for burn excision or debridement involving between 4% and 9% TBSA. Code 01951 covers less than 4% TBSA; add-on code 01953 covers each additional 9% TBSA or part thereof beyond the first 9%. Code 01958 covers obstetric procedures. For a 6% TBSA burn, 01952 is the primary anesthesia code.

Question 16

A procedure has 8 base units and anesthesia lasted 90 minutes. Using the standard 15-minute time unit convention, what is the total anesthesia allowable if the conversion factor is $90?

  1. $1,170
  2. $990
  3. $1,260 (correct answer)
  4. $1,350
Explanation: Formula: (Base Units + Time Units) × Conversion Factor. 90 minutes ÷ 15 minutes per unit = 6 time units. (8 base + 6 time) × $90 = 14 × $90 = $1,260. Base units reflect the relative complexity of the procedure; time units reflect the duration of anesthesia at one unit per 15 minutes. Answer A incorrectly uses 5 time units (75 min); answer D incorrectly adds an extra unit not supported by the documented time.

Question 17

An epidural placed for labor analgesia is subsequently used for a cesarean section when the patient's labor fails to progress. Which CPT® anesthesia code is reported for this conversion scenario?

  1. 01960
  2. 01968 (correct answer)
  3. 01961
  4. 01965
Explanation: CPT® 01968 covers anesthesia for cesarean delivery following neuraxial labor analgesia — specifically when an epidural placed for labor is converted or extended for a cesarean section. Code 01961 covers cesarean delivery without prior labor epidural; 01960 covers vaginal delivery; 01965 covers incomplete or complete abortion procedures. The labor-to-cesarean conversion must be captured with 01968.

Question 18

A patient requires anesthesia for an off-pump coronary artery bypass graft (CABG) — a beating-heart procedure performed without cardiopulmonary bypass. Which CPT® anesthesia code is reported?

  1. 00566 (correct answer)
  2. 00562
  3. 00560
  4. 00580
Explanation: CPT® 00566 covers anesthesia for direct coronary artery bypass grafting without pump oxygenator (off-pump CABG). Code 00562 covers anesthesia for cardiac procedures using pump oxygenator (on-pump CABG); 00560 covers general heart and pericardium procedures; 00580 covers heart transplantation. The presence or absence of cardiopulmonary bypass is the primary differentiator in cardiac anesthesia code selection.

Question 19

A patient requires anesthesia for a lumbar laminectomy. Which CPT® anesthesia code range covers procedures on the spine and spinal cord?

  1. 00400-00474
  2. 00500-00580
  3. 00600-00670 (correct answer)
  4. 00700-00797
Explanation: CPT® anesthesia codes 00600-00670 cover procedures on the spine and spinal cord, including laminectomy. Code 00630 covers procedures in the lumbar region; 00640 covers lumbar spine manipulation. The thorax surface (00400), intrathoracic (00500), and upper abdominal (00700) ranges do not include spinal cord procedures. The spine range (00600-00670) is the correct section.

Question 20

A patient requires anesthesia for an inguinal hernia repair. Which CPT® anesthesia code specifically covers hernia repair in the lower abdomen?

  1. 00840
  2. 00846
  3. 00900
  4. 00830 (correct answer)
Explanation: CPT® 00830 covers anesthesia for herniorrhaphy (hernia repair) in the lower abdomen, including inguinal, femoral, and umbilical hernias. Code 00840 covers other intraperitoneal lower abdominal procedures; 00846 covers radical hysterectomy; 00900 covers male genitalia procedures. Inguinal hernia repair is specifically designated 00830 in the lower abdominal anesthesia range.
