CPC Exam Dumps - AAPC Certified Professional Coder Questions and Answers

This scenario describes acytogenetic-type analysis targetingchromosomal abnormalities, performed using fluorescence-based microscopy techniques (commonly conceptually aligned with FISH-type evaluation). The question explicitly states thatno specific CPT code accurately describes the service, which signals that anunlistedcode is required. In CPT, the88299code is the unlisted procedure code forcytogenetic studies, used when a chromosomal/genetic laboratory procedure does not have a more specific existing CPT descriptor. The other unlisted options correspond to different laboratory sections:84999is an unlisted chemistry procedure,88199is an unlisted cytopathology procedure, and88749is not the correct unlisted cytogenetics code for this context as presented. CPC exam technique: match thedomainfirst (chromosomes → cytogenetics), then select the appropriateunlisted code within that domainwhen the stem says no specific CPT code exists. Proper use of unlisted codes also implies documentation of method, purpose, and comparables for payer review, but the test asks only for the correct unlisted CPT code.

Selective catheter placement coding follows thehighest-order selective catheterization achievedwithin a vascular family, plus additional selective placements when adifferent vascular familyis entered. Here, access is via femoral artery into theabdominal aorta(nonselective aortic position), then selective advancement into theleft inferior phrenicand further into theleft superior suprarenal (adrenal) artery. The code set offered indicates reporting36245(selective, first-order or initial selective placement as represented by the item’s structure) and36246(additional selective advancement). Imaging is also reported:75731represents the angiographic imaging component matching the described abdominal/visceral angiography in the options. Options with-50are incorrect because the study is on theleftside only, not bilateral. Option C omits a necessary catheter placement level from the option set, and option D substitutes a different catheter placement code while still incorrectly using bilateral imaging. Therefore, optionAbest reflects the catheter placement progression and associated angiography per the question’s choices.

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.

When hypertension and heart disease are documented together, a cause-and-effect relationship is presumed unless stated otherwise.

Category I11 (Hypertensive heart disease) is used.

Additional codes from I50.- (heart failure) are assigned if applicable.

This follows ICD-10-CM Official Coding Guidelines.

For drug testing for cocaine and methamphetamines with a single analysis using direct optical observation and a subsequent confirmation for cocaine, the appropriate codes are:

80305 for the initial drug test (presumptive).

80353 for the confirmation test of cocaine.

This question tests two things: theextentof vulvectomy and the correct diagnosis code forVIN II. VIN II corresponds tomoderate vulvar dysplasia, which is coded asN90.1. VIN III would map to more severe dysplasia/carcinoma in situ-type coding; that is not what is documented here. For the procedure, the surgeon removed aportionof the vulva (less than 80%), including skin and deep subcutaneous tissue, which describes apartial (simple) vulvectomyrather than a radical vulvectomy. CPT56625represents asimple partial vulvectomy(partial removal). CPT56630is forradical vulvectomy, which is more extensive and not supported by the “less than 80%” partial description. Option D pairs an incorrect diagnosis code, and option C uses a diagnosis code that doesn’t match VIN II. Therefore, the correct combination is56625 with N90.1.

This is arepeatdecompression at apreviously operatedlumbar level, described as “repeat exploration laminotomy,” which aligns with there-explorationcode family rather than a primary discectomy code. The procedure includesbilateral foraminotomyat a single lumbar interspace (L1–L2), meaning it is performed onboth sidesat the same level. In the answer choices,63042represents re-exploration/decompression (repeat procedure) and is appropriately markedbilateralwith-50. The foraminotomy component at the lumbar level is represented by63044, also performed bilaterally, so63044-50is appropriate when the code is unilateral by descriptor and the work was done on both sides. Options C and D reference63030/63035, which are associated with lumbar discectomy/decompression primary coding patterns, not the “repeat exploration laminotomy” scenario presented. Option A incorrectly lists 63044 twice rather than using bilateral reporting. Therefore,63042-50, 63044-50is the best match within the provided options.

A tympanoplasty repairs aperforated tympanic membrane. The key phrase “doesnotremove the mastoid” means this istympanoplasty without mastoidectomy, which is correctly represented by69631in the answer set. Codes that include mastoid work (or represent different tympanoplasty variants) are incorrect because the documentation explicitly states the mastoid was not removed. Diagnosis coding should reflect both thechronic otitis mediaand theperforation. In the options,H66.92represents otitis media (as offered) andH72.92represents perforation of the tympanic membrane (as offered). Although the clinical story specifies the left ear, the provided diagnosis options do not include laterality; on CPC-style questions, you choose the best match among the answer choices. Therefore, the correct combination within this question’s choices is69631 with H66.92 and H72.92, matching tympanoplasty without mastoidectomy plus the documented conditions.

In this scenario, the procedure involved the excision of a large sacral pressure ulcer with deep tissue damage that required muscle and bone removal and was followed by a layered flap closure. The coding reflects both the extent of the ulcer and the procedure performed:

1. CPT® Code 15937: This code describes excision of a pressure ulcer with muscle and bone removal followed by flap closure, which matches the detailed procedure performed on the sacral ulcer.

2. ICD-10-CM Code L89.156: This code is used for a stage 4 sacral pressure ulcer, indicating the presence of deep tissue damage down to muscle and possibly bone, which aligns with the clinical findings.

Explanation of other options:

A. 15933, L89.153 and B. 15931, L89.153: These codes do not adequately describe the excision with muscle and bone removal nor the stage 4 severity of the ulcer.

C. 15935, L89.156: Although L89.156 is correct for a stage 4 ulcer, 15935 does not account for both muscle and bone excision with flap closure.

Therefore, the correct answer is D. 15937, L89.156, accurately capturing the procedure performed and the severity of the ulcer.

Kerat/o = cornea

-itis = inflammation

Keratitis specifically means inflammation of the cornea, which is the transparent anterior portion of the eye.

Other options are incorrect because:

Blepharitis = inflammation of the eyelid

Conjunctivitis = inflammation of the conjunctiva

Scleritis = inflammation of the sclera
