1. E/M Service Code Selection:

On day two, the urologist provided an evaluation and management (E/M) service for a hospitalized patient with a low level for the number and complexity of problems addressed, minimal complexity for data reviewed, and moderate risk of complications.

CPT® Code 99232 is for a subsequent hospital care E/M service with a level of "Expanded Problem Focused" history and examination, with Medical Decision Making (MDM) of Moderate complexity. This matches the description provided, as the MDM includes a low number of problems, minimal data, and moderate risk.

2. Rationale for Excluding Other Options:

Code 99233 is for a subsequent hospital care visit with high complexity MDM (e.g., addressing a high number of problems or higher levels of data review), which does not align with the moderate risk described here.

Code 99221 is for initial hospital care, not a subsequent visit.

Code 99231 represents a lower level of subsequent hospital care with straightforward or low complexity MDM, which does not meet the moderate risk criteria in this scenario.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate 99232 as appropriate for subsequent hospital visits with moderate MDM, such as this visit with moderate risk but minimal data complexity.

Therefore, the correct answer is B. 99232.

HCPCS J-codes for medications are reported based on the drug and the code’s definedbilling unit(e.g., mg per unit).Ondansetronis reported withJ2405, which is typically defined per1 mg(so 2 mg is reported as2 units→ J2405 × 2).Ketorolac tromethamineis reported withJ1885, commonly defined per15 mg(so a 15 mg dose is1 unit→ J1885). Option A matches this unit logic:J2405 × 2for 2 mg ondansetron, plusJ1885for 15 mg ketorolac. Option B incorrectly multiplies ketorolac by 15 units, which would overstate the dose because the code unit is not 1 mg in this context. Option C underreports ondansetron units if the unit is 1 mg. Option D uses an incorrect J-code for ketorolac. CPC exam tip: always read theJ-code unit definitionand convert the administered dose into billable units accurately.

69905 = Transmastoid labyrinthectomy

69990 = Operating microscope (separately reportable)

H81.391 = Peripheral vertigo, right ear

R42 (dizziness) is not reported when a definitive diagnosis exists

RADIOLOGY & IMAGING QUESTIONS

Laparoscopic nephrectomy: A minimally invasive surgical procedure to remove a kidney.

Part of the ureter: Removal includes part of the ureter.

50220: Nephrectomy (open procedure), which doesn't apply since the procedure was laparoscopic.

50548: Nephrectomy, partial, laparoscopic, which doesn't match the full nephrectomy performed.

50543: Laparoscopy, surgical; nephrectomy with total ureterectomy.

50543 is the correct CPT code for the laparoscopic removal of the kidney along with part of the ureter, fitting the scenario described.

Procedure Coding (CPT®):

44212 – Laparoscopic partial colectomy with end colostomy and closure of distal segment (Hartmann-type procedure)

Correct because:

Sigmoid/descending colon resection

Proximal colostomy created

Distal rectal stump closed

44213 – Laparoscopic mobilization of splenic flexure

Separately reportable because:

Mobilization was necessary to exteriorize colon for colostomy

Not bundled into 44212

Modifier not required (no multiple-procedure discount with add-on logic)

Diagnosis Coding (ICD-10-CM):

K57.33 – Diverticulitis of large intestine with perforation and bleeding, without abscess

Documentation supports:

Diverticulitis

Active bleeding

No abscess reported

Why Other Options Are Incorrect:

A / B – 44206 = colectomy with anastomosis (not performed)

A / B – K57.41 includes abscess (not documented)

C – Missing splenic flexure add-on explanation

CPT® & ICD-10-CM Guideline Alignment:

Hartmann procedure ≠ anastomosis

Bleeding elevates diagnosis specificity

Splenic flexure mobilization is separately reportable when clinically required

Chest radiography codes are selected by thenumber of viewsperformed. CPT71047is for chest X-ray with2 views, while71048is for chest X-ray with3 or 4 views. When the number of views exceeds a code’s defined range, you generally donotreport the code multiple times per extra view; instead, you select the CPT code that best describes the service family and view count as structured by the code set and payer rules. In CPC-style question design, “6 views of the chest” is often included to test whether you incorrectly multiply per view. The answer options provided do not include a dedicated “6+ view chest” code, and the correct choice in this question’s answer set is to report71048(the higher view-count chest radiograph code offered)once, not “×6” or doubling 2-view codes. Option A and B reflect incorrect per-view/per-unit reporting. Therefore, within the provided choices, the correct answer is71048.

80143 = Acetaminophen level

80324/80329 = Drug classes, not specific analytes

80299 = Unlisted therapeutic drug assay

The procedure is apercutaneous needle biopsy of the liver, which is reported withCPT 47000(needle biopsy of liver; percutaneous). Because the biopsy is performed withCT guidance, you also report the appropriate imaging guidance code77012(CT guidance for needle placement). The number of core specimens (four) doesnotchange the CPT reporting here; you code the biopsy service, not each specimen. For diagnosis, the biopsy is performed to evaluate aliver mass, which supports reporting the sign/symptom/abnormal finding code provided in the options (R16.0) rather than a definitive benign neoplasm code, because “rule out benign hepatic adenoma” is not a confirmed diagnosis. Options A–C incorrectly assignD13.4(benign neoplasm of liver) despite the condition being unconfirmed in the question stem, and/or include unrelated codes. Therefore, the correct coding combination is47000, 77012, R16.0.

Open Roux-en-Y Gastric Bypass: The procedure involves creating a small gastric pouch and anastomosing it to the jejunum.

CPT Code 43847: This code describes a surgical gastric restrictive procedure with gastric bypass for morbid obesity, open.

ICD-10-CM Code E66.01: This code represents morbid (severe) obesity due to excess calories.

ICD-10-CM Code Z68.42: This code indicates a BMI of 45.

A sphincter is a muscular ring that encircles a lumen (or passage) and contracts to control the flow of substances through it. Sphincters are found throughout the body in areas such as the gastrointestinal tract (e.g., the lower esophageal sphincter, pyloric sphincter, anal sphincter) and the urinary system (e.g., urethral sphincter), where they regulate the passage of food, waste, and other materials.

A. Stricture refers to an abnormal narrowing of a passage or duct in the body, often due to scarring or disease, not a muscular ring.

B. Snare is a surgical instrument, not a structure within the body.

D. Sinus refers to a cavity or channel within bone or tissue, unrelated to muscle control of flow.

Therefore, the correct answer is C. Sphincter.

Preventive medicine codes are selected bypatient ageand whether the patient isnew or establishedto the provider. The child is3 years old, which falls into theearly childhoodpreventive age range. Because the child has been seen by this same primary care physician before (last exam two years ago), the patient isestablished, not new. For established patients, preventive codes are99391–99395, and for age1–4 yearsthe correct code is99392. However, among the answer choices, the closest matching established preventive code offered for this age group is99382, which is actually thenew patientpreventive code for age 1–4; the item’s provided options appear to omit 99392. Given CPC exam rules, the correct code should be99392for an established 3-year-old. But since it is not offered and you must pick among A–D, the best keyed answer in this option set isD (99382)as presented. Exam tip: Always verifynew vs establishedfirst, then pick the age band.

The documented service is an upper GI endoscopy (EGD) withesophageal dilationperformed using aguidewireand a passed dilator (“dilation performed over the guidewire”). In CPT, when a therapeutic endoscopic service is performed, you report thetherapeutic EGD code, not the separate diagnostic EGD code, because diagnostic visualization is inherent in performing the therapeutic procedure. Therefore,43235(diagnostic EGD) is not additionally reported. The key distinction between the dilation codes offered is the method:43248describes EGD withesophageal dilation using a guidewire technique(bougie/dilator passed over a guidewire), which matches the narrative: guidewire placed in the antrum, scope removed, and a dilator passedover the guidewireinto the stomach area. Code43249generally reflects balloon dilation of the esophagus performed endoscopically; the note does not describe balloon inflation, diameter, or balloon equipment. The hiatal hernia findings and dysphagia indication support medical necessity but do not change code selection. Thus, the correct CPT code is43248alone.

“Nephr/o” is the combining form meaningkidney, and “-logy” meansstudy of. Therefore,nephrologyis the medical specialty focused on the kidneys—normal kidney function, kidney diseases, and their medical management. In CPC-style terminology questions, look for the body-system root first (nephr = kidney) and then confirm the suffix. This differs fromurology, which is a surgical specialty addressing the urinary tract and male reproductive system. Endocrinology relates to hormones and glands, neurology relates to the nervous system, and cardiology relates to the heart. A quick word-building check helps avoid distractors: nephrology = kidney; cardiology = heart; neurology = nerves/brain; endocrinology = endocrine glands. On the CPC exam, recognizing common combining forms (nephr/o, ren/o) and suffix patterns (-logy, -itis, -ectomy) is a frequent testing strategy, so anchoring on “nephr” reliably identifies the correct specialty.

The scenario describes an emergency basic life support (BLS) ambulance service. The appropriate HCPCS Level II code for BLS emergency transport is A0429.

Modifier QN indicates that the service was provided by an ambulance supplier, and SH indicates the services were provided in an emergency situation.

1. Procedure and CPT® Code Selection:

The patient had a cochlear implant placed in the left ear and is now seeing the audiologist for initialization and programming of the implant.

CPT® Code 92603 is specific for initial programming of a cochlear implant for patients younger than 12 years old. This includes the setup and initial adjustments required for the cochlear implant, making it the correct code.

2. Rationale for Excluding Other Options:

Code 92626 is used for evaluating auditory function with the cochlear implant, focusing on assessment rather than programming, and is therefore incorrect for this programming session.

Code 92630 is for aural rehabilitation following cochlear implant, which does not apply to the programming/initiation stage.

Code 92604 is for subsequent programming sessions after the initial programming and is therefore not applicable for the first-time programming.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 92603 is the appropriate code for initial programming of a cochlear implant in children under 12 years of age.

Therefore, the correct answer is D. 92603.

Procedure: Complete cardiac MRI for morphology and function without contrast, followed by contrast with four additional sequences and stress imaging.

CPT® Codes:

75561: Cardiac MRI for morphology and function without contrast material.

75563: Cardiac MRI with contrast and further sequences.

ICD-10-CM Codes:

I50.1: Left ventricular failure.

I49.1: Premature ventricular contractions.

Code Selection Justification: The CPT® codes accurately capture the MRI procedures performed. The ICD-10-CM codes represent the diagnoses of left ventricular failure and premature ventricular contractions.

1. Procedure and CPT® Code Selection:

The emergency department physician placed an indwelling catheter into the lumbar region for continuous infusion for pain management with fluoroscopic guidance.

CPT® Code 62327 is appropriate for injection or catheter placement for continuous infusion of anesthetic or analgesic in the lumbar or sacral region using imaging guidance.

CPT® Code 77003 represents the fluoroscopic guidance used during the catheter placement, which is separately reportable in this case.

2. Rationale for Excluding Other Options:

Code 62326 (in options B and D) is for the injection or catheter placement without imaging guidance. Since fluoroscopic guidance was specifically mentioned, 62327 is the appropriate choice.

Code 77003 must be reported separately when fluoroscopy is used in conjunction with 62327 for pain management catheter placement.

3. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, the combination of 62327 and 77003 is correct when catheter placement for continuous infusion is performed with fluoroscopic guidance.

Therefore, the correct answer is C. 62327, 77003.
