CPC Exam Dumps : Certified Professional Coder (CPC) Exam

Modifier selection for discontinued procedures depends onsettingandhow far the procedure progressed. In the CPT modifier framework,-53(Discontinued Procedure) is used when a physician terminates a procedure due toextenuating circumstances or those that threaten the well-being of the patientafter the procedure has begun. Here, anesthesia was given, the incision was made, and then respiratory distress occurred—clearly a patient safety issue requiring stopping the surgery. That matches modifier-53for the surgeon’s claim. Modifier-74is afacilitymodifier (commonly used by ambulatory surgery centers/hospitals for discontinued outpatient procedures after anesthesia), not the surgeon’s CPT modifier in the typical CPC context. Modifier-47indicates anesthesia by the surgeon, which is not the key fact here and does not represent discontinuation. Modifier-52is for reduced services when a service is partially reduced at the physician’s discretion, not terminated for patient safety. Therefore, the oral surgeon reports21060-53.

The diagnosis “tracheal stenosis present from birth” is acongenital malformation, which is coded withQ32.1(congenital stenosis of trachea) rather than an acquired tracheal disorder code. For anesthesia coding, tracheoplasty is a major airway/tracheal surgical procedure and maps to the appropriateairway/trachea anesthesiacategory represented by00320in the answer set. Because the patient is aninfant (6 months old), anesthesia qualifies for the extreme age add-on99100(anesthesia for patient of extreme age, under 1 year or over 70 years). Options includingJ39.8reflect an acquired/other tracheal disorder category rather than congenital stenosis, which conflicts with “from birth.” Options that omit 99100 miss the age-related qualifying circumstance. CPC exam strategy: always code congenital conditions withQ-codeswhen documented as present from birth, and remember99100for patients < 1 yearwhen anesthesia qualifying circumstances are reported. Therefore,00320, 99100, Q32.1is correct.

The procedure documented is a modified Fontan procedure → 33615 (Fontan-type single-ventricle repair per the choices given).

The congenital diagnosis documented is double inlet ventricle → Q20.2.

Why the other options are incorrect based on the statements provided:

Q20.4 is not “double inlet ventricle” as stated in the question.

Adding Q20.1 is not supported by the documentation (the question only states double inlet ventricle).

Therefore, the best match is 33615, Q20.2 → A.
