AAPC Updated CPC Exam Questions and Answers by alvey

1. Procedure and CPT® Code Selection:

The patient underwent a cardiac MRI to assess the morphology and function of the heart under stress, involving both non-contrast and contrast-enhanced imaging. Additionally, pharmacological stress testing was performed to evaluate the coronary arteries.

CPT® Code 75563 is appropriate for a cardiac MRI with both stress and rest imaging, including morphology and function studies with contrast and pharmacologic stress testing. This code accurately captures the entire scope of the MRI study described in this case.

Modifier 26 is applied to indicate the professional component of the service if the cardiologist is providing only the interpretation and not the technical component.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code I25.118 is used for atherosclerotic heart disease with unstable angina. This code accurately reflects the diagnosis provided in the scenario.

3. Rationale for Excluding Other Options:

Code 75559 (option B) represents a cardiac MRI without stress testing, which does not cover the pharmacologic stress component performed here.

Code 75557 (in option D) is for a limited cardiac MRI that does not include both stress and non-stress imaging, so it is incorrect for this comprehensive test.

ICD-10-CM Code I25.110 (in options C and D) is for atherosclerosis with angina pectoris without unstable angina, making I25.118 more appropriate given the diagnosis of unstable angina.

4. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines support the use of 75563 for comprehensive cardiac MRI studies with stress testing, both with and without contrast.

Therefore, the correct answer is A. 75563-26, I25.118.

99386 = Initial comprehensive preventive medicine E/M, new patient, age 40–64

Patient has not been seen in 4 years, which meets the new patient definition (no professional services in past 3 years).

Age = 63

No problem-oriented complaints → preventive service only

Why others are incorrect:

99396 / 99397 – Established patient codes

99387 – Age 65+

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.
