It ensures that coders understand how to apply codes for chemistry panels, cultures, and histopathological diagnostics.
- Topic 19: Evaluation & Management Services: This section of the exam measures the skills of coding specialists and covers office visits, hospital care, consultations, and other E/M services. It tests the understanding of time-based coding, medical decision-making, and history/exam components per current CMS guidelines.
Free AAPC CPC Exam Actual Questions
Note: Premium Questions for CPC were last updated On Aug. 02, 2026 (see below)
What ICD-10-CM coding is reported for a patient who has hypertension and CKD stage 2?
When hypertension and chronic kidney disease (CKD) are documented together, ICD-10-CM assumes a cause-and-effect relationship.
I12.9 = Hypertensive chronic kidney disease with stage 1--4 CKD
N18.2 = CKD stage 2
I12.0 is only for CKD stage 5 or ESRD, which does not apply here.
Therefore, the correct code combination is I12.9, N18.2.
Refer to the exhibit.

What CPT coding is reported?
CPT Code 55706: Biopsy, prostate; needle, transperineal, stereotactic template guided saturation sampling, including imaging guidance.
This code accurately describes the procedure performed. The documentation clearly states that a stereotactic template was used to guide the biopsy needles, and multiple samples were taken (saturation biopsies). This code includes imaging guidance.
CPT Code 76942: Ultrasonic guidance for needle placement (e.g., biopsy, aspiration, injection, localization device), imaging supervision and interpretation.
Although 55706 includes imaging guidance, code 76942 is also reported separately because the transrectal ultrasound provided initial diagnostic images and was then used for guidance during the biopsy. This is supported by the documentation which states 'Using a B & K ultrasound probe, a transrectal ultrasound of the prostate was obtained. Once this was done...a biopsy needle is inserted into the prostate...under ultrasound guidance.' This indicates distinct uses of the ultrasound.
Important Note: While some sources suggest that 76942 and the diagnostic transrectal ultrasound code (76872) are bundled, it's crucial to consult the latest National Correct Coding Initiative (NCCI) edits for the most up-to-date guidance.
CPT Code 55706: Biopsy, prostate; needle, transperineal, stereotactic template guided saturation sampling, including imaging guidance
CPT Code 76942: Ultrasonic guidance for needle placement (e.g., biopsy, aspiration, injection, localization device), imaging supervision and interpretation
AAPC Coder's Desk Reference: This resource provides detailed information on coding guidelines and procedures.
NCCI Edits: Always check the most current NCCI edits to confirm coding combinations.
Patient has cervical spondylosis with myelopathy. The surgeon performed a bilateral posterior laminectomy with facetectomies at each level and foraminotomies performed between interspaces C5-C6 and C6-C7. Bilateral decompression of the nerve roots is achieved.
What CPT coding is reported?
Cervical spondylosis with myelopathy: Condition requiring decompressive surgery.
Bilateral posterior laminectomy, facetectomies, foraminotomies: Procedures performed to decompress nerve roots.
Interspaces C5-C6 and C6-C7: Specific levels where the procedures were performed.
CPT code 63045 is used for the initial cervical laminectomy, and 63048 is for each additional segment. The combination covers the decompression across two interspaces.
The gallbladder is in which organ system?
The gallbladder is part of the digestive system. It stores and concentrates bile, which aids in the digestion of fats.
It works closely with the liver and biliary tract, all of which belong to the digestive system, making C the correct answer.
A patient who is 37 weeks' gestation is admitted to labor and delivery for a cesarean delivery. An external cephalic version was performed successfully several days ago and she now presents in labor, fully dilated, and the fetus has returned to a footling presentation.
What anesthesia code is reported?
To determine the correct anesthesia code for a cesarean delivery with specific conditions, we review the following codes:
01961 is defined as 'Anesthesia for cesarean delivery only,' which aligns with this scenario, as the patient is admitted for a cesarean section.
01960 refers to anesthesia for a vaginal delivery, which does not apply here as the delivery is via cesarean.
01967 is for 'Anesthesia for planned vaginal delivery,' which also does not apply due to the cesarean route.
01958 is used for planned vaginal delivery that may involve a complicated scenario, but since the procedure is a cesarean section, this code is not appropriate.
Given that the patient is in labor for a cesarean section and has had a previous external cephalic version, 01961 is the correct answer.
