CPC AAPC Certified Professional Coder (CPC) Exam Free Practice Exam Questions (2026 Updated)

The injection into the trochanteric bursa under ultrasonic guidance is coded with CPT® 20611, which describes an injection of a major joint or bursa with ultrasound guidance. The modifier -LT indicates the procedure was performed on the left side.

38573 includes comprehensive laparoscopic staging with bilateral pelvic lymphadenectomy and paraaortic sampling

All listed components are bundled into this code

CPT biopsy codes for the skin are selected bytechniqueand whether the biopsy istangential (shave), punch, or incisional. In this scenario, three different biopsy techniques are performed onthree separate lesions: anincisional biopsyof a deep lesion (upper arm), apunch biopsy(forearm), and ashave biopsy(shoulder). The correct primary codes are11106(incisional biopsy, single lesion),11104(punch biopsy, single lesion), and11102(tangential/shave biopsy, single lesion). Because each is a distinct lesion and a distinct technique, CPT coding uses the appropriatebase codesfor each technique rather than “add-on additional lesion” codes, and you do not automatically apply modifier-51in CPT-answer logic unless the question specifically tests payer/claim-processing conventions. The CPC exam typically expects the straightforward reporting of all three correct biopsy codes when performed on separate lesions with separate specimens submitted. Therefore, optionBis the best match.

This is anestablished patient office visitcoded byMDM(or time, but time is not provided). Problems:one acute, uncomplicated illness(URI) → supportslowproblem complexity. Data: no labs/imaging ordered or reviewed →minimal/nonedata. Risk: although a prescription is given, MDM level is determined by2 of 3elements (Problems, Data, Risk). Here, only the risk might approach moderate due to prescription management, butproblems and data remain low/minimal, so the overall MDM doesnotmeet moderate. Therefore, the visit is best supported atlow MDM, which corresponds to99213for an established patient. It is more than minimal (99212) because a focused exam and management plan are documented, but it does not meet the higher complexity required for 99214/99215 (multiple problems, significant data review, or high-risk management). CPC exam focus: don’t let a single element (like antibiotics) automatically “force” a higher code—MDM requires meeting the level intwo elements.

Medicare provides specific codes for screening colonoscopy based on the patient's risk factors. For a Medicare patient scheduled for a screening colonoscopy who is at high risk (such as those with a history of intestinal polyps), the appropriate code is G0105.

G0105 is used for colorectal cancer screening; colonoscopy on individuals at high risk.

CPT Code 62290: Discography, lumbar, single or multiple levels, radiological supervision and interpretation

This code accurately describes the procedure performed. The documentation indicates a lumbar discography was performed at a single level (L3-4) with radiological supervision (C-arm visualization).

ICD-10-CM Code M54.50: Low back pain, unspecified

This code is the most appropriate diagnosis based on the documentation. The preoperative diagnosis states "Low back pain possible spinal stenosis L3-4." While spinal stenosis was considered, it was not confirmed. The postoperative diagnosis indicates no evidence of spinal stenosis or discogenic pathology. Therefore, the definitive diagnosis is low back pain.

Why other options are incorrect:

62292: This code is for a discography with injection of contrast and/or medication for therapeutic purposes. The documentation doesn't indicate any therapeutic injection was performed.

M48.061 and M48.07: These codes represent spinal stenosis, which was not confirmed in the postoperative diagnosis.

For the procedure involving access to the subclavian vein and advancing a catheter to the inferior vena cava for injection and imaging, the following codes are used:

36010 for the catheter placement.

75825-26 for the supervision and interpretation of the imaging.

Modifier -26 indicates the professional component of the radiological supervision and interpretation.

1. Procedure and CPT® Code Selection:

The procedure performed was a hysteroscopy to examine the uterine cavity due to abnormal vaginal bleeding. This is a diagnostic hysteroscopy.

CPT® Code 58555 is specifically for a diagnostic hysteroscopy to examine the uterine cavity, which aligns with the procedure performed in this case.

2. Rationale for Excluding Other Options:

Code 58558 is for a hysteroscopy with a surgical procedure, such as biopsy or removal of a lesion or polyp, which was not performed in this case.

Code 58579 is an unlisted procedure code for the female genital system and is unnecessary here because there is a specific code (58555) for diagnostic hysteroscopy.

Code 58578 is also an unlisted hysteroscopic procedure code and is not appropriate when a specific diagnostic code exists.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines indicate that 58555 should be used for diagnostic hysteroscopy procedures without any surgical intervention.

Therefore, the correct answer, following CPT® guidelines, is C. 58555.

72158 = MRI lumbar spine without and with contrast

M54.42 = Low back pain with sciatica, left side

Separate pain codes are not reported redundantly

This is aninitial hospital service(admitted this morning; “reason for admission”), so the correct E/M family isinitial hospital inpatient/observation carerather than subsequent hospital care (99232/99233). The encounter includes a detailed history, comprehensive exam elements focused on abdominal pathology, and meaningful initial management: NPO, IV fluids,IV morphine, ordering and reviewing lab panels, and ordering imaging (ultrasound and HIDA) with possible surgical consultation—supporting at leastmoderate MDM, consistent with99222in typical CPC exam mapping. Diagnosis coding: “rule out cholecystitis” is not a confirmed inpatient discharge diagnosis in the provided note; at this stage the physician’s final assessment isRUQ abdominal pain, rule out cholecystitis. Therefore, you report thesign/symptomcodeR10.11 (right upper quadrant pain)rather thanK81.9(cholecystitis, unspecified), because cholecystitis is not established as definitive in the note. Option A correctly pairs an initial hospital E/M code with the symptom diagnosis supported by documentation.

The outermost protective layer of the skin is called the epidermis. It serves as a barrier to protect the body against environmental elements, pathogens, and helps to retain moisture. The epidermis itself is composed of several sub-layers, with the stratum corneum being the outermost layer.

1. Procedure and CPT® Code Selection:

The procedure described is a craniectomy to access and remove a supratentorial intracerebral hematoma using a suction device.

CPT® Code 61314 is specific for a craniectomy or craniotomy for evacuation of a hematoma, supratentorial (within the upper portion of the brain), and includes any required dural repair and closure. This code precisely describes the procedure performed to remove the hematoma.

2. Rationale for Excluding Other Options:

Code 61154 is used for a burr hole procedure for the evacuation of a hematoma, which is a less invasive approach and does not involve a craniectomy.

Code 61313 is for a craniectomy or craniotomy to evacuate an infratentorial hematoma, which is located in the lower portion of the brain (posterior fossa) and is not applicable here.

Code 61312 is for evacuation of an epidural or subdural hematoma and does not apply to an intracerebral hematoma as described in this case.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 61314 is the appropriate code for craniectomy procedures aimed at removing supratentorial intracerebral hematomas, as it covers the full scope of the documented procedure.

Thus, the correct answer is A. 61314.

44010 = Biopsy of small intestine, single or multiple

Reported once only, regardless of number

74150 = CT abdomen without contrast

Other codes describe MRI or combined studies

80430 = Growth hormone suppression panel

Individual tests are reported with units

MEDICINE & CARDIOLOGY

Cholecyst- = gallbladder

Entero- = intestine

-ostomy = creation of an opening

Cholecystenterostomy is the correct term for surgically creating a connection between the gallbladder and the intestine.

This aligns with surgical terminology commonly tested in the CPT® digestive system section (40000–49999).

47000 = Percutaneous liver biopsy

77021 = MRI guidance for needle placement

Multiple cores are included in the biopsy code

S06.0X1A = Concussion with brief LOC

V40.5XXA = Driver injured in collision with fixed object

V47.5XXA = Car accident, driverExternal cause codes correctly describe mechanism and role.

Procedure Coding:

72158 – MRI, lumbar spine; without contrast, followed by with contrast

Single comprehensive code

Diagnosis Coding:

M54.42 – Low back pain with sciatica, left side

Why Other Options Are Incorrect:

B / C – Incorrectly unbundling MRI codes

D – Coding additional unspecified low back pain is inappropriate
