Question 1
1, 780.60, 462, 786.2
Correct Answer:
See solution for the supported answer
Explanation:
Rationale: According to the ICD-9-CM Official Coding Guidelines Section I.B.6, signs and symptoms are reported when a related definitive diagnosis has not been established. The flu was suspected but not established therefore we code the patient’s presenting symptoms. In the Index to Diseases, see Fever directing you to 780.60. She also has a sore throat, in the Index to Diseases, look up Pharyngitis directing you to code 462. In the Index to Diseases, look up Cough directing you to 786.2. Verify these codes in the Tabular List
Question 2
78-year-old patient with bilateral, lower lobe lung cancer has been in the hospital for seven days with a tunneled chest tube in place to drain fluid from the pleural space. The chest tube currently is inserted between the 4th and 5th intercostal space on the left side. There is a very bad infection at the insertion site. The physician removes this chest tube and inserts another chest tube between the 5th and 6th intercostal space on the left side to continue fluid drainage. The tube placed today is just the same as the one removed, only sterile. What CPT® and ICD-9-CM codes are reported?
Correct Answer:
32550, 32552-51, 996.69, 162.5
Explanation:
Rationale: Code 32552 represents the indwelling tunneled chest tube removal and code 32550 the insertion of a new indwelling catheter/tube. In the Index to Diseases, look up Catheterization/Pleural Cavity which directs you to 32550-32552. Read both codes to confirm the selections. The infection at the insertion site of the chest tube is indexed under Complications/infection/due to (presence of) any device, implant, or gaft/catheter NEC, directing you to code 996.69. The ICD-9-CM code for the lung cancer is found using the Neoplasm Table.Look up lung/lower lobe. In the malignant primary column we are directed to code 162.5. Verification in the Tabular List confirms code selection
Question 3
A patient underwent bilateral nasal/sinus diagnostic endoscopy. Finding the airway obstructed the physician fractures the middle turbinates to perform the surgical endoscopy with total ethmoidectomy and bilateral nasal septoplasty. What CPT® codes are reported?
Correct Answer:
31255, 30520-51
Explanation:
Rationale: According to the CPT® guidelines for coding of endoscopies, a surgical sinus endoscopy includes a sinusotomy and diagnostic endoscopy. In the Index, look up Ethmoidectomy/Endoscopic directing you to 31254-31255. Code 31255 represents a total ethmoidectomy. In the Index, look up Septoplasty, this directs you to code 30520. The fracturing of the turbinates is inclusive to the procedures and not reported separately, since the physician is fracturing the turbinates to perform the ethmoidectomy. Modifier 50 indicates these procedures were both performed bilaterally and modifier 51 is reported with code 30520 to indicate multiple procedures performed at same session, for maximum reimbursement
Question 4
55-year-old female smoker presents with cough, hemoptysis, slurred speech, and weight loss. Chest X-ray done today demonstrates a large, unresectable right upper lobe mass, and brain scan is suspicious for metastasis. Under fluoroscopic guidance in an outpatient facility, a percutaneous needle biopsy of the lung lesion is performed for histopathology and tumor markers. A diagnosis of small cell carcinoma is made and chemoradiotherapy is planned. What CPT® and ICD-9-CM codes are reported?
Correct Answer:
32405, 77002-26, 162.3
Explanation:
Rationale: In the CPT® Index, look up Biopsy/Lung/Needle. This directs you to code 32405. Code 77002 is the appropriate code for the fluoroscopic guidance as indicated by the parenthetical statement under code 32405 and by reviewing the code descriptor for 77002. Modifier 26 is appended to report the professional component. We have a diagnosis of small cell carcinoma of the lung which is code 162.3. In the Index, go to the Neoplasm Table and look under lung/upper lobe and the ―Primary‖ column code 162.3 is listed. The signs and symptoms are no longer codes since we do have this definitive diagnosis (ICD-9-CM Guidelines Section I.B.6) Brain metastasis is suspected but not confirmed so it would not be reported. The chemotherapy is planned but not performed so it would not be reported either
Question 5
A surgeon performs a high thoracotomy with resection of a single lung segment on a 57-year-old heavy smoker who had presented with a six-month history of right shoulder pain. An apical lung biopsy had confirmed lung cancer. What CPT® and ICD-9-CM codes are reported?
Correct Answer:
32484, 162.3
Explanation:
Rationale: A segment of the lung is removed. In the CPT® Index, look up Removal/Lung/ Single Segment. This directs you to code 32484. We have a confirmed diagnosis of apical lung cancer, a cancer in an upper lobe, which is code 162.3. The term apical means the tip of a pyramidal or rounded structure, so apical lung cancer means the tumor/cancer is located at the top or upper lobe of the lung. We find this by looking in the Neoplasm Table under lung/upper lobe. In the primary malignant column we are directed to code 162.3

What the Course Entails and Exam Details

This targeted guide is not a full training course but an optimized tool to measure and refine your proficiency in the CPT 30000 Series portion of the CPC exam. It entails a thorough review of Current Procedural Terminology (CPT®) codes ranging from 30000 to 39999. The core skills and specific medical systems covered include:

  • Respiratory System: Surgical procedures on the nose, accessory sinuses, larynx, trachea and bronchi, lungs, and pleura.

  • Cardiovascular System: Procedures on the heart and pericardium, as well as arteries and veins.

  • Hemic and Lymphatic Systems: Interventions involving the spleen, lymph nodes, and lymph channels.

  • Mediastinum and Diaphragm: Specific surgical codes for these critical anatomical areas. Beyond code selection, you must also demonstrate a solid understanding of related anatomy, physiology, and the official CPT coding guidelines and modifiers specific to these complex systems.


What to Expect in the Final Exam

While this study guide is section-specific, it prepares you for the entire 100-question CPC examination. The full CPC exam is a grueling four-hour test, delivered in a multiple-choice format. It is an "open book" exam, allowing the use of your official AMA CPT®, ICD-10-CM, and HCPCS Level II code books. The CPT 30000 Series section typically contains about 6 dedicated questions that present complex surgical scenarios. These questions will test your ability to correctly sequence codes, apply modifiers, and differentiate similar procedures. To earn your CPC certification, you must achieve a passing score of at least 70%.


How to Study and Exam Centers

Preparation for this section must be intense and precise. Begin by highlighting and making notes in your official AMA CPT® Professional edition codebook, focusing specifically on the CPT 30000-39999 range. Take multiple practice exams and timed quizzes that target this numeric range to improve your speed. Create study materials for respiratory and cardiovascular anatomy, as a deep knowledge of these systems is essential for code selection. The final CPC exam is administered by the AAPC. You can choose to take it in person at local AAPC chapter locations or authorized testing centers, or remotely via an online-proctored format, which is scheduled through the AAPC website and facilitated by partners like Meazure Learning.


Job Opportunities from the Course

A CPC certification, backed by a strong competency in coding complex surgical procedures like the CPT 30000 series, significantly enhances your career path and earning potential.
