CPC Exam Dumps : Certified Professional Coder (CPC) Exam

Procedure Coding:

56633 – Radical vulvectomy (removal of > 80%), including deep subcutaneous tissue

Documentation supports greater than 80% vulvar removal

Deep tissue involvement confirms radical procedure

Diagnosis Coding:

D07.1 – Carcinoma in situ of vulva

VIN III = high-grade squamous intraepithelial lesion

Classified as carcinoma in situ, not benign dysplasia

Why Other Options Are Incorrect:

56620 / 56625 / 56630 – Partial or simple vulvectomy

N90.1 – Mild vulvar dysplasia (incorrect severity)

ICD-10-CM Official Guideline:

VIN III is coded as D07.1, not N90.x.

CPT70450describes aCT of the head/brain without contrast. When aradiology facilityperforms the technical portion (scanner, technologist, supplies) and theprovider only interprets and reportsthe study, the provider bills theprofessional componentusing modifier-26. That is exactly what the vignette describes: the radiology facility performed the scan, and the provider received images and provided the interpretation—so the provider reports70450-26. Reporting70450alone would imply billing the global service (professional + technical), which would be incorrect because the provider did not supply the equipment/technical resources. Modifier-TCis used to bill thetechnical component, which would be reported by the facility, not the interpreting provider in this scenario. Modifier-26-TCtogether is not appropriate because it would contradict itself (professional and technical simultaneously). CPC exam tip: always determinewho performedthe technical work andwho interpreted; then use-26for interpretation-only billing.

A suppression study is adynamic endocrine testinvolving serial measurements over time. CPT80430represents thesuppression function testitself (the study framework), while the individual lab analytes measured during the test are reported with their specific assay codes based on the test protocol. The scenario includesfive glucose testsandfive human growth hormone (HGH) testsperformed as part of the study. Glucose testing is reported with82947per test, and growth hormone testing is reported with83003per test. Because the stem specifiesfive of each, correct reporting includes80430plus82947 × 5and83003 × 5. Options that report only one unit of 82947/83003 (or reduce the number of tests) fail to reflect the documented serial testing frequency. CPC exam tip: when a dynamic study is described, do not stop at the function test code—also capture theserial analyte measurementswhen the question explicitly provides the number of lab draws/tests. Therefore, the correct coding is80430, 82947 × 5, 83003 × 5.
