AAPC Certified Professional Coder (CPC) Exam CPC Exam Dumps: Updated Questions & Answers (March 2026)

Basal cell carcinoma is amalignantskin neoplasm, so the excision is coded from11600–11646(malignant lesion excision), not11400–11446(benign lesion excision). The scalp is in the anatomic group that includesscalp/neck/hands/feet/genitalia, and the excised diameterincluding marginsdetermines the malignant excision code range. A size of3.7 cmfalls into the3.1–4.0 cmcategory, which corresponds to11624for malignant excision in that location group. Closure is separately reportable when it is anintermediate (layered) repair, so you add12032(intermediate repair, scalp/axillae/trunk/extremities;2.6–7.5 cm) when documentation supports layered closure beyond simple repair. Diagnosis coding should reflectbasal cell carcinoma of scalp/neck, which isC44.41. Options that use benign excision or benign diagnosis codes are incorrect for basal cell carcinoma.

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.

Moderate sedation codes are selected by (1)patient ageand (2) whether the sedation is provided by thesame physician performing the procedureor by a different provider. The stem states theorthopedist provides the sedation and the reduction, so the sedation is provided by thesame physicianwho performs the procedure. For age, the patient is5 years old, which falls into the≥5 yearscategory. Therefore, the correct initial moderate sedation code is99152(moderate sedation provided by the same physician/other qualified provider performing the procedure; patient age 5 years or older; initial 15 minutes). The documented time is21 minutes, which supports only theinitialcode (it does not reach the threshold needed to report an additional 15-minute increment add-on). Code99151is for patientsunder 5 years, so it does not apply. Codes99155/99156are for sedation provided by adifferentprovider than the one performing the procedure. CPC exam tip: age cutoffs matter—exactly 5years old uses the “5 years or older” code set.

The CPT code 11960 is used for the insertion of tissue expanders for other than breast, which includes the scalp in this case. The procedure involves inserting the tissue expanders, closing the skin, and gradually increasing the volume of the expanders until a satisfactory outcome is achieved for repairing the scalp defect. The other options do not accurately describe the procedure performed on the scalp.

AMA's CPT® Professional Edition (current year)

The Office of Inspector General (OIG) operates under the Department of Health and Human Services (HHS) and is specifically responsible for detecting, investigating, and preventing fraud, waste, and abuse in federal healthcare programs such as Medicare and Medicaid.

This is a key compliance and regulatory topic on the CPC exam.

In this encounter, the correct coding order follows ICD-10-CM guidelines for coding multiple conditions when AIDS (B20) is documented, as it takes precedence. The patient's diagnosis of AIDS, documented with code B20, is reported as the primary diagnosis since it is a chronic condition. The M17.31 code is used to document unilateral primary osteoarthritis of the right knee, unrelated to AIDS but causing the patient's knee pain.

Explanation of each answer choice:

A. B20, M17.31: Correctly lists AIDS (B20) as the primary diagnosis and osteoarthritis of the right knee (M17.31) as the secondary diagnosis.

B. Z21, M08.861: Z21 represents asymptomatic HIV, not AIDS, which is incorrect here, and M08.861 is the code for juvenile idiopathic arthritis, not relevant in this case.

C. M17.11, B20: Incorrect as M17.11 is for unilateral primary osteoarthritis of the right knee, not left, and does not prioritize B20 as required.

D. M17.31, B20: Incorrect because it does not list B20 as the primary diagnosis, which is necessary per coding guidelines when AIDS is documented.

Thus, the correct answer is A. B20, M17.31.

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.

A “subcutaneous cardiac rhythm monitor” describes animplantable loop recorder(insertable cardiac monitor) placed under the skin for long-term rhythm surveillance. When the entire monitor system isremoved, CPT provides a specific removal code rather than using pacemaker/ICD removal codes.33286is the CPT code forremoval of an insertable cardiac monitor. The timing (14 months after implantation) supports that this is not an immediate post-op revision but a standard removal after monitoring is complete or the device is no longer needed. The distractors represent other cardiac device services:33241is removal of an implantable defibrillator pulse generator (not a loop recorder), and33272/33273relate to other cardiac device procedures rather than removal of an insertable monitor. CPC strategy: identify the device category—loop recorder/insertable cardiac monitor—and match the service—removal—to the dedicated code. This avoids incorrectly reporting pacemaker/ICD codes, which are different devices with different procedural work and coding families.

This question is testing recognition of amaxillofacial prosthetic servicerather than an ophthalmology procedure code. The vignette describesfabrication of a prosthesis using silicone materialswithmodificationsintended to restorecosmetic appearanceafter loss/damage of an eye. Among the provided options,21086is the CPT code that corresponds to fabrication of afacial prosthesis(commonly silicone-based) with the intent of external restoration. The other codes in this small cluster represent different facial/craniofacial repair or prosthetic services and do not match silicone prosthesis fabrication described in the scenario. CPC exam technique: focus on the key nouns—“fabricates a prosthesis,” “silicon materials,” “cosmetic appearance restoration”—which point away from repair codes and towardprosthetic fabrication. Also note the question is not about insertion of an ocular implant during enucleation/evisceration, but about crafting an external prosthetic device. Therefore, the correct selection is21086.
