AAPC CPC - Certified Professional Coder (CPC) Exam

The human heart hasfour cardiac valves:tricuspid,pulmonic,mitral (bicuspid), andaortic. These valves regulate one-way blood flow through the heart’s chambers and into the great vessels. Themitralvalve lies between the left atrium and left ventricle; thetricuspidvalve lies between the right atrium and right ventricle; theaorticvalve controls flow from the left ventricle to the aorta. “Femoral” refers to thefemur(thigh bone) and thefemoral artery/veinin the groin/thigh region, not a structure of the heart. While veins can contain valves (e.g., in the legs), the term “femoral valve” isnot recognized as a standard named cardiac valve. On CPC-style anatomy questions, distractors often use real anatomical words from other body regions to test whether you know the specific list of true cardiac valves.

Thelunulais the pale, crescent-shaped area visible at the base of some fingernails and toenails (most commonly the thumb). It is part of thenail unit, associated with the nail matrix where nail formation occurs. Because the lunula is anail structure, a biopsy “of the lunula” is anail biopsy, even though a punch tool is also commonly used in skin biopsies. CPC exam questions frequently test precise anatomical vocabulary, especially for integumentary structures (skin, nail, hair). The distractors “eye” and “brain” are unrelated, and “skin” is tempting because punch biopsies are typically skin procedures; however, the question specifically identifies thelunula, which is not a skin landmark. Coding and documentation accuracy depend on knowing these terms because nail procedures often have different code families and clinical considerations than routine skin biopsies. Correct identification starts by mapping the term to its anatomical system: lunula → nail apparatus.

Warthin's tumor, also known as papillary cystadenoma lymphomatosum, is a benign tumor of the salivary glands, most commonly affecting the parotid gland. It typically presents as a painless, slow-growing mass near the angle of the jaw.

Anesthesia coding is based on thesurgical/procedural serviceand the anatomic/physiologic region involved, not the underlying symptom alone. An electrophysiologic (EP) study with radiofrequency ablation is acardiac electrophysiologyprocedure, typically mapped to anesthesia codes in the0053xrange (cardiovascular procedures, often involving intracardiac catheter-based interventions). In this option set,00537is the anesthesia code that corresponds to EP/cardiac ablation-type procedures. Physical status modifier selection then reflects the patient’s systemic health. The question specifies an “otherwise healthy 35-year-old,” which corresponds toASA Physical Status P1(a normal healthy patient). Therefore, the correct combination is00537-P1. The distractors include anesthesia codes from different procedure categories (e.g., radiology/anesthesia for imaging or other cardiac procedures) and/or the wrong physical status (P2 implies mild systemic disease). CPC exam tip: first match theprocedure family(EP/ablation → cardiovascular anesthesia category), then assign the appropriateASA physical statusbased on the patient’s baseline health.

1. Procedure Details and CPT® Code Selection:

The patient underwent a catheter placement in the proper hepatic artery (a visceral artery), followed by dye injection and imaging to identify a stenosis, and finally a percutaneous transluminal angioplasty of the artery.

Code 36247 is appropriate for selective catheter placement in the third-order or more selective branch of a visceral artery. Since the proper hepatic artery is a selective branch accessed from the left femoral artery, this code accurately describes the catheter placement.

Code 75736 is for angiography of a selective visceral artery following catheter placement, which matches the imaging procedure performed here.

Code 37248 describes a percutaneous transluminal angioplasty of a visceral artery, which is the therapeutic intervention performed to treat the stenosis in the proper hepatic artery.

2. Modifiers:

Modifier 26 is used with 75736 to denote the professional component of the imaging service.

Modifier 59 indicates that the imaging (75736) is a distinct procedural service, separate from the therapeutic angioplasty (37248).

Modifier 51 is applied to 37248 to indicate it was a secondary procedure in addition to the diagnostic imaging and catheter placement.

3. Exclusion of Other Options:

Code 36253 (in choices A and D) is for selective catheter placement in a different vessel and does not apply to the hepatic artery.

Code 75726 is for non-selective abdominal aortography, which does not match the specific selective imaging of the hepatic artery.

4. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, each step in an angiographic and interventional radiology procedure is coded based on the level of vessel accessed, imaging performed, and therapeutic intervention completed, which is all accurately represented by 36247, 75736-26-59, and 37248-51.

Based on CPT® and AAPC coding guidelines, the correct answer is C. 36247, 75736-26-59, 37248-51.

You said:

1. Procedure and CPT® Code Selection:

The patient underwent a partial nephrectomy (removal of part of the left kidney) via a laparoscopic approach.

CPT® Code 50543 is specifically used for a laparoscopic partial nephrectomy, which is an accurate description of this procedure.

2. Rationale for Excluding Other Options:

Code 50548 is used for a laparoscopic radical nephrectomy, which involves the complete removal of the kidney and surrounding structures; therefore, it does not apply to this partial nephrectomy.

Code 50220 represents an open partial nephrectomy, not a laparoscopic approach, and is therefore incorrect for this procedure.

Code 50546 is for a laparoscopic radical nephrectomy with bilateral removal of kidneys, which is not applicable in this case where only a partial removal of the left kidney was performed.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate that the use of 50543 is appropriate for any laparoscopic partial nephrectomy, regardless of the laterality, and it specifically identifies laparoscopic technique over open surgery.

Therefore, based on CPT® guidelines, the correct answer is C. 50543.

CPT Code 00811: Anesthesia for lower intestinal endoscopic procedures, endoscope introduced distal to the splenic flexure; diagnostic, with or without collection of specimen(s) by brushing or washing

This code is reported for anesthesia services provided during a colonoscopy that is diagnostic in nature.

ICD-10-CM Code D62: Acute posthemorrhagic anemia

This is the most accurate postoperative diagnosis. The operative report states "Anemia due to acute blood loss."

ICD-10-CM Code N18.6: End stage renal disease

This code captures the patient's documented history of ESRD.

ICD-10-CM Code Z99.2: Dependence on renal dialysis

This code is necessary to report the patient's dialysis status, as it affects the overall risk of the procedure.

Why other options are incorrect:

00812: This code is for therapeutic colonoscopies, not diagnostic.

D64.9: This code is for anemia, unspecified. D62 is more specific to the patient's condition.

K62.5: This code is for lower gastrointestinal bleeding, but the anemia is the primary diagnosis in this case.

The patient with malignant lymphoma is administered Rituximab (800 mg) and Benadryl (100 mg) intravenously.

Procedure Description:

Administration of Rituximab (800 mg) intravenously.

Administration of Benadryl (100 mg) intravenously.

HCPCS Level II Coding:

J9312: Injection, Rituximab, 10 mg.

For 800 mg, report 80 units of J9312.

J1200: Injection, Diphenhydramine HCl, up to 50 mg.

For 100 mg, report 2 units of J1200.

HCPCS Level II coding guidelines for intravenous drug administration.

Procedure Coding (CPT®):

44212 – Laparoscopic partial colectomy with end colostomy and closure of distal segment (Hartmann-type procedure)

Correct because:

Sigmoid/descending colon resection

Proximal colostomy created

Distal rectal stump closed

44213 – Laparoscopic mobilization of splenic flexure

Separately reportable because:

Mobilization was necessary to exteriorize colon for colostomy

Not bundled into 44212

Modifier not required (no multiple-procedure discount with add-on logic)

Diagnosis Coding (ICD-10-CM):

K57.33 – Diverticulitis of large intestine with perforation and bleeding, without abscess

Documentation supports:

Diverticulitis

Active bleeding

No abscess reported

Why Other Options Are Incorrect:

A / B – 44206 = colectomy with anastomosis (not performed)

A / B – K57.41 includes abscess (not documented)

C – Missing splenic flexure add-on explanation

CPT® & ICD-10-CM Guideline Alignment:

Hartmann procedure ≠ anastomosis

Bleeding elevates diagnosis specificity

Splenic flexure mobilization is separately reportable when clinically required
