AAPC CPC - Certified Professional Coder (CPC) Exam

93454 = Coronary angiography

R07.9 = Chest pain, unspecified

CAD code is not reported when ruled out

“Three-view imaging of both hips and the pelvis” corresponds toCPT 73523(bilateral hips with pelvis, 3–4 views). Because the same study is repeated laterthe same daydue to a new event (fall from bed) and is interpreted by thesame radiologist, the correct repeat modifier concept is-76(repeat procedure by thesamephysician/qualified health professional). The most accurate reporting is73523for the first study and73523-76for the repeat study. Among the provided options,Dis the only choice that includes both73523and the correct repeat-by-same modifier-76. The inclusion of-51in option D reflects a multiple-procedure concept that is not the primary modifier logic for a true repeat of the same radiologic service; however, the CPC exam intent here is to recognize73523and that the repeat isby the same radiologist, requiring-76(not -77). Key learning point: select the correctstudy code by views, then apply-76for same-provider repeat interpretation.

In CPT® Surgery Guidelines, a " separate procedure " code is used to identify a service that is typically performed as part of a larger procedure and should not be coded separately when it is an integral component of that primary service. However, it may be reported independently if it is performed alone or is unrelated to the primary procedure.

A. is true because a separate procedure may be reported if it is performed independently or is unrelated to the primary procedure.

B. is true, as " separate procedure " codes are not reported in addition to the code for the primary procedure when they are part of the total procedure.

C. is correct because " separate procedure " designation indicates that the service is often part of a more comprehensive procedure but can be reported separately when performed alone.

D. is false because modifier 79 is not used for unrelated " separate procedures. " Instead, modifier 59 is typically used to indicate a " distinct procedural service " when reporting a separate procedure that is unrelated to the primary service.

Therefore, the correct answer is D. To identify a service designated as a " separate procedure " that is reported with an unrelated primary service, append modifier 79 to the code.

Modifier 53 is used to report a discontinued procedure. It indicates that a procedure was started but terminated due to the patient ' s well-being being at risk. In this scenario, the percutaneous transluminal coronary angioplasty was attempted but stopped because of an anatomical problem that created a risk for the patient, preventing the completion of the procedure.

35875 = Thrombectomy, femoral-popliteal artery

RT = Right side

75710-26 = Angiography, extremity, unilateral, professional component

AnExcludes1note means“NOT CODED HERE”and indicates that the two conditionscannot be reported togetherbecause they are eithermutually exclusiveor one condition is inherently included in the other in that context. In practical CPC exam terms, if an Excludes1 note applies between two codes, you generallydo not assign both codes on the same encounter. This is different fromExcludes2, which means the excluded condition isnot part of the code, but the patient may haveboth conditions at the same time, soboth codes may be reportedif supported by documentation. NEC (Not Elsewhere Classifiable) points you to a more specific code when available; NOS (Not Otherwise Specified) reflects insufficient detail in documentation. The question is specifically about a note that prevents reporting two conditions together—this is the hallmark definition ofExcludes1under ICD-10-CM conventions and is heavily tested on CPC exams.

Impending myocardial infarction is reported with I21.3 for a myocardial infarction (acute). The shortness of breath, which is a symptom, is coded separately as R06.02. According to ICD-10-CM guidelines, when a definitive diagnosis is established, the diagnosis code is sequenced first followed by symptom codes.

ICD-10-CM (current year), Chapter 9: Diseases of the Circulatory System (I00-I99), ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.9.e.4.

The procedure described involves a LeFort I reconstruction, which is a type of orthognathic surgery performed to correct deformities of the midface. In this scenario, the surgeon performed the reconstruction in two pieces, moving the upper jawbone forward and repositioning the teeth of the maxilla. According to the CPT® guidelines, CPT code 21146 describes a LeFort I (maxilla only) osteotomy, two-piece segment, including bone grafts (includes obtaining autografts). This code matches the description provided.

Formultiple gestation vaginal deliveries, CPT global obstetric care is generally reported as the global code for thefirst fetus(here59400: antepartum + vaginal delivery + postpartum), and an additionaldelivery-onlycode for each additional fetus (here59409) with an appropriate modifier (commonly-51in exam-style choices). You donotreport59400 twicebecause the global package is not duplicated for each baby; only the additional delivery service is added for the additional fetus. Diagnosis coding: this is atwin pregnancy, dichorionic/diamniotic, third trimester→O30.043. Delivery outcome for twins →Z37.2, and weeks of gestation →Z3A.36. Because delivery occurred at36 weeks(preterm threshold is < 37 weeks), and the options use thepreterm labor with preterm deliverycategory with fetus identifiers, the correct pairing shown isO60.14X1 and O60.14X2(fetus 1 and fetus 2). Option D is the only one matching correct CPT multiple-delivery structure and appropriate diagnosis set.

1. Procedure and CPT® Code Selection:

The scenario describes the removal and replacement of an inflatable penile prosthesis due to erectile dysfunction.

CPT® Code 54416 is specifically used for the removal and replacement of a multi-component inflatable penile prosthesis. This code accurately describes the procedure performed.

2. Rationale for Excluding Other Options:

Code 54401 represents the initial insertion of a multi-component inflatable penile prosthesis but does not cover removal and replacement, making it inappropriate for this scenario.

Code 54400 is for the insertion of a non-inflatable (malleable) penile prosthesis, which does not apply here as the prosthesis is inflatable.

Code 4417 does not exist in the CPT® coding system and is likely a typo or incorrect option.

3. AAPC and CPT® Coding Guidelines:

According to AAPC and CPT® guidelines, 54416 is the correct code when an inflatable prosthesis requires both removal and replacement, without the need for additional modifiers for this procedure.

Therefore, the correct answer based on CPT® guidelines is D. 54416.
