CPC Exam Dumps - Certified Professional Coder (CPC) Exam

Procedure Coding (CPT®):

31287 – Nasal/sinus endoscopy, surgical; with sphenoidotomy

Correct because the surgeon performed a surgical endoscopic sphenoidotomy to evaluate and treat sphenoid sinus injury.

No CSF leak repair was performed, so codes 31290–31291 are not appropriate.

31231-59 – Nasal endoscopy, diagnostic

Diagnostic endoscopy is separately reportable because:

It was performed to evaluate traumatic injury

It is not bundled into the surgical service when it provides distinct diagnostic information

Modifier -59 indicates a separate and distinct service per NCCI edits.

Diagnosis Coding (ICD-10-CM):

S02.109A – Unspecified fracture of base of skull, initial encounter for closed fracture

The anterior cranial fossa fracture with sphenoid sinus involvement qualifies as a skull base fracture

No CSF leak is documented

Correct 7th character “A” for initial encounter

Why Other Options Are Incorrect:

A – Incorrect format and duplicated CPT logic

B – 31267 = maxillary sinus, wrong sinus

D – 31291 includes CSF leak repair, which was not performed

00813 = Anesthesia for colonoscopy

QK = Medical direction of 2–4 cases

99100 = Extreme age

99140 = Emergency anesthesia

1. Procedure and CPT® Code Selection:

The urinalysis performed was non-automated and without microscopy.

CPT® Code 81002 is appropriate for a non-automated urinalysis without microscopy. This code accurately reflects the test performed in the office.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code R30.0 is used for dysuria, which was one of the patient's presenting symptoms.

ICD-10-CM Code R10.30 is used for lower abdominal pain, another presenting symptom.

Since the urinalysis ruled out a urinary tract infection, N39.0 (UTI) is not appropriate as a final diagnosis.

3. Rationale for Excluding Other Options:

Code 81000 (in options A and B) is for a urinalysis with microscopy, which was not performed here.

N39.0 is used when a UTI is confirmed, which is incorrect for this case since the urinalysis was negative, ruling out UTI.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines recommend coding based on the symptoms when a specific diagnosis (such as UTI) is ruled out. Therefore, R30.0 and R10.30 are appropriate symptom codes for this encounter.

Thus, the correct answer is C. 81002, R30.0, R10.30.

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.

The spleen is a part of the lymphatic system, which is responsible for filtering blood, removing damaged blood cells, and supporting immune function. The spleen contains lymphocytes that help fight infections and regulate the immune response.

A. Nervous: The nervous system includes the brain, spinal cord, and nerves, unrelated to immune function.

B. Endocrine: The endocrine system regulates hormones through glands like the thyroid and pancreas, not directly involved with blood filtration or immune cell production.

C. Digestive: While the spleen is located near digestive organs, it does not play a role in digestion.

Thus, the correct answer is D. Lymphatic.

For a patient with a mass in the left lower lung suspected to be cancer that is currently documented as a tumor of uncertain behavior, with existing ovarian cancer with metastases to the liver, the ICD-10-CM codes are:

D38.1: Neoplasm of uncertain behavior of bronchus and lung.

C56.9: Malignant neoplasm of unspecified ovary.

C78.7: Secondary malignant neoplasm of liver and intrahepatic bile duct.

D38.1 is used because the behavior of the lung tumor is uncertain, and C56.9 and C78.7 are used to document the known primary and metastatic cancers.

ICD-10-CM guidelines

AMA's CPT® Professional Edition (current year)

Procedure Code:

90945 – Continuous renal replacement therapy (CRRT), daily

Includes repeated low-level E/M monitoring

Correct for CVVH

Diagnosis Codes:

I10 – Essential hypertension

N18.9 – Chronic kidney disease, unspecified

Why others are incorrect:

90935 / 90937 – Intermittent hemodialysis

90947 – Pediatric CRRT

ICD-9 codes (112.9, 110) are invalid

1. Procedure and CPT® Code Selection:

The patient underwent a percutaneous needle biopsy of the liver with ultrasound guidance to assess primary biliary cirrhosis.

Code 47000 is the CPT® code for a percutaneous liver biopsy. This code encompasses the biopsy procedure itself.

Ultrasound guidance is commonly inherent to biopsy procedures, and guidance is not separately reported if the main code (47000) includes the technique used.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code K74.5 is the correct code for primary biliary cirrhosis, which is specifically indicated in this case.

K74.3 is the code for other specified cirrhosis of the liver but is less specific than K74.5, making K74.5 the appropriate choice here.

3. Exclusion of Other Codes:

Code 47100 (option A) is for an open liver biopsy, which does not apply to this percutaneous procedure.

Codes 10005 (biopsy with imaging guidance) and 76942 (ultrasound guidance) would be redundant or incorrect since the main procedure code, 47000, sufficiently describes a percutaneous liver biopsy.

4. AAPC and CPT® Coding Guidelines:

AAPC guidelines state that guidance is included in certain biopsy codes when performed for the targeted organ, such as in 47000 for a liver biopsy.

Therefore, based on CPT® and ICD-10-CM coding rules, the correct answer is C. 47000, K74.5.
