Verified Exam Questions and Answers

Question 1: CPT Code for Laparoscopic Procedure
Question: A 50-year-old patient undergoes a laparoscopic cholecystectomy with
intraoperative cholangiography. What is the appropriate CPT code for this pro-
cedure?
Answer: 47563
Explanation: CPT code 47563 describes a laparoscopic cholecystectomy with
cholangiography, as outlined in the CPT 2025 Professional Edition. This code
is used when the gallbladder is removed laparoscopically, and an intraoperative
cholangiogram is performed to assess bile duct patency. Documentation must
confirm the laparoscopic approach, cholangiography, and medical necessity (e.g.,
gallstones). Incorrect coding, such as using 47562 (without cholangiography),
could lead to claim denials.
2.
Question 2: ICD-10-CM for Heart Failure
Question: A patient is diagnosed with chronic systolic heart failure due to is-
chemic cardiomyopathy. What is the correct ICD-10-CM code?
Answer: I50.22
Explanation: ICD-10-CM code I50.22 represents chronic systolic (congestive)
heart failure, as per the 2025 ICD-10-CM Official Guidelines. The code specifies
the chronic nature and systolic dysfunction, often linked to ischemic cardiomy-
opathy. Documentation must include the heart failure type, chronicity, and un-
derlying cause to support coding accuracy and justify related treatments, such as
medication management.
