AAPC Updated CPC Exam Questions and Answers by avie

CPT® code 36252 describes selective catheter placement of the main renal artery with angiography of both kidneys, which matches the procedure of selectively catheterizing the right and left renal arteries and performing angiography. Additionally, CPT® code 75625-26 is for an abdominal aortography with interpretation and report. The -26 modifier indicates that the professional component of the service was performed.

CPT Code 43246: Esophagogastroduodenoscopy, with transoral insertion of intra-abdominal tube (e.g., gastrostomy or jejunostomy)

This code describes the attempted PEG tube placement.

Modifier -52: Reduced services. This modifier is appended because the procedure was aborted and the PEG tube was not successfully placed.

ICD-10-CM Code K94.29: Other specified disorders of digestive system

This code captures the patient ' s chronic feeding requirement, which is the reason for the attempted PEG tube placement.

ICD-10-CM Code K44.9: Diaphragmatic hernia without obstruction or gangrene

This code reports the small hiatal hernia that was found during the procedure.

For bronchoscopy coding, you report the CPT code that describes thetype of scopeand thekey procedure performed. When bronchoscopicbiopsiesare performed, the service is reported with the appropriate bronchoscopy-with-biopsy code, and youdo not multiply the code by the number of biopsy samples. CPT codes for endoscopy procedures generally represent theoverall service, regardless of how many specimens are obtained during that one session at the same anatomic site category. In this question set,31628is the correct code representingflexible bronchoscopy with transbronchial lung biopsy(the biopsy component is the coded element).31625describes bronchoscopy with a different work element (not the biopsy service intended here), making it an incorrect distractor. Options that apply “×5” reflect a common novice error—billing per specimen rather than per procedure. On CPC exams, the presence of multiple biopsies is usually included to test whether you understand that endoscopic biopsy codes arenot reported per sample.

IV hydration is coded byduration. CPT96360is forinitial intravenous hydration(typically the first hour). CPT96361is an add-on code foreach additional hourbeyond the initial hour, reported when the hydration time exceeds 60 minutes and meets the additional-hour threshold. The scenario documents hydration for1 hour and 30 minutes (90 minutes). That supports reporting theinitial hour(96360) plusone additional hour(96361) because the infusion extends beyond the initial hour and reaches the qualifying threshold for an additional hour as defined by CPT time rules (time is rounded/assigned based on midpoints, not per minute). The other options usetherapeutic infusioncodes (96365/96366), which are for medications/drugs, not for hydration with normal saline when the primary purpose is hydration. CPC exam tip: if the service is specifically “hydration” and the fluid is normal saline for dehydration/heat exhaustion, use96360/96361and apply time-based logic.
