Sample CANPC Practice Questions

Try these sample questions to test your CANPC exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which CPT code range is reserved for anesthesia services?

A.00100-01999

B.10021-19499

C.20100-29999

D.62320-64999

Explanation: Anesthesia services in CPT are coded using the 00100-01999 range. These codes describe anesthesia administration grouped by anatomic site (head, neck, intrathoracic, lower abdomen, upper leg, etc.) rather than by surgical procedure.

2An anesthesiologist provides anesthesia for an open hemicolectomy. Which CPT code best represents anesthesia for procedures on the lower intestine?

A.00790

B.00400

C.00540

D.00100

Explanation: CPT 00790 reports anesthesia for intraperitoneal procedures in upper abdomen including laparoscopy; lower intestine procedures such as hemicolectomy fall under intra-abdominal anesthesia codes 00790-00797. 00790 is the primary code reported for an open hemicolectomy when no more specific code applies.

3When two surgical procedures are performed during the same anesthesia session, how should anesthesia be reported?

A.Report only one anesthesia code with the highest base unit value

B.Report both anesthesia codes with modifier 51

C.Report both codes and add the base units together

D.Report the code listed second in CPT order

Explanation: Per CPT anesthesia guidelines, when multiple surgical procedures are performed during the same operative session, only ONE anesthesia code is reported, the one with the highest base unit value (the most complex). Total time for all procedures is reported with that single code.

4Which CPT code reports anesthesia for a vaginal delivery only (no labor analgesia component)?

A.01960

B.01967

C.01968

D.01961

Explanation: CPT 01960 reports anesthesia for vaginal delivery only. Codes 01967/01968 are for neuraxial labor analgesia, and 01961 is anesthesia for cesarean delivery only.

5An anesthesiologist provides anesthesia for total knee arthroplasty. Which CPT code is correct?

A.01402

B.01382

C.01400

D.01480

Explanation: CPT 01402 reports anesthesia for open procedures on the knee joint, including total knee arthroplasty.

6Which anesthesia code is used for a coronary artery bypass graft (CABG) WITH pump oxygenator?

A.00567

B.00566

C.00560

D.00580

Explanation: CPT 00567 reports anesthesia for direct coronary artery bypass grafting WITH pump oxygenator. 00566 is the same procedure WITHOUT pump oxygenator (off-pump CABG).

7Anesthesia for a diagnostic upper endoscopy (EGD) is reported with which CPT code?

A.00731

B.00740

C.00810

D.00790

Explanation: CPT 00731 reports anesthesia for upper gastrointestinal endoscopic procedures, endoscope introduced proximal to duodenum, not otherwise specified. This was a 2018 revision splitting GI endoscopy anesthesia by upper vs lower.

8Anesthesia for an intracranial procedure such as craniotomy for tumor resection is reported with which code?

A.00211

B.00190

C.00170

D.00300

Explanation: CPT 00211 reports anesthesia for craniotomy or craniectomy for evacuation of hematoma. For other intracranial procedures including tumor resection, codes 00210-00218 in the head subsection apply; 00211 is commonly tested for hematoma evacuation. For craniotomy for tumor specifically, 00214 may apply.

9Which CPT code reports anesthesia for a transurethral resection of prostate (TURP)?

A.00914

B.00910

C.00920

D.00865

Explanation: CPT 00914 reports anesthesia for transurethral procedures (including urethrocystoscopy) for transurethral resection of prostate (TURP).

10Anesthesia for cesarean delivery only is reported with:

A.01961

B.01960

C.01968

D.01967

Explanation: CPT 01961 reports anesthesia for cesarean delivery only.

About the CANPC Exam

AAPC specialty credential for anesthesia and pain management coders. Validates expertise in anesthesia CPT coding (00100-01999), the anesthesia formula (Base Units + Time Units + Modifying Units × Conversion Factor), anesthesia modifiers (AA, QY, QK, QX, QZ, AD, P1-P6, G8/G9), pain management procedures (epidural, facet, RFA, peripheral nerve blocks), and chronic pain ICD-10-CM coding (G89.x).

CANPC Study Tips from Top Performers

1Master anesthesia modifiers and the medical-direction concept: AA personally performed; QY/QK direct (1 / 2-4); QX/QZ CRNA with/without direction; AD supervision >4

2Know the 'one anesthesia code per session per anatomic site' rule — report most complex code only

3Understand epidural vs transforaminal coding: epidural 62321/62322/62323 (interlaminar without/with imaging) vs transforaminal 64479-64484 (per nerve root level + each addt'l)

4Memorize key add-on units: 99100 (extreme age <1 or >70), 99116 (hypothermia), 99135 (controlled hypotension), 99140 (emergency)

Frequently Asked Questions

What is the anesthesia formula?

Anesthesia payment = (Base Units + Time Units + Modifying Units) × Conversion Factor. Base Units come from ASA Relative Value Guide for the specific anesthesia code. Time Units are typically 1 unit per 15 minutes (round up partial units per payer). Modifying Units include ASA Physical Status (P3+), age (99100), CPB (99135), hypothermia (99116). Conversion Factor varies by payer.

What's the difference between AA, QY, QK, QX, QZ?

AA = personally performed by anesthesiologist (no concurrent cases). QY = anesthesiologist medically directing 1 CRNA. QK = anesthesiologist medically directing 2-4 concurrent CRNAs. QX = CRNA service with medical direction. QZ = CRNA service WITHOUT medical direction (independent CRNA). AD = anesthesiologist medical SUPERVISION of >4 concurrent (lower payment than direction).

What are common pain management CPT codes?

Epidural injections without imaging guidance: 62321 (cervical/thoracic), 62322 (lumbar/sacral); WITH imaging: 62325, 62327. Transforaminal: 64479-64484. Facet joint injections paravertebral: 64490-64495. Facet RFA: 64633-64636. Trigger point: 20552 (1-2 muscles), 20553 (3+). Peripheral nerve blocks 64400-64488.
