1. Procedure and CPT® Code Selection:

The physician administered the MMRV (measles, mumps, rubella, and varicella) vaccine subcutaneously and dose 3 of Hepatitis B vaccine intramuscularly. The physician also provided counseling on routine immunizations.

CPT® Code 90460 is used for immunization administration with counseling by the physician for patients 18 years or younger for the first or only component of each vaccine.

CPT® Code 90461 is used for each additional component in a vaccine with counseling.

90710 is the code for the MMRV vaccine.

90744 is the code for the Hepatitis B vaccine (pediatric).

2. Application of 90460 and 90461:

For the MMRV vaccine (which has four components: measles, mumps, rubella, and varicella), 90460 is reported once for the first component, and 90461 is reported three times (once for each additional component).

For the Hepatitis B vaccine, 90460 is reported again since it is a separate vaccine with one component.

3. Rationale for Excluding Other Options:

Option A (90471, 90472 x 4, 90707, 90746) uses codes for vaccine administration without counseling and incorrect vaccine codes (90707 for MMR instead of MMRV and 90746 for adult Hepatitis B instead of pediatric).

Option B and Option D also contain incorrect vaccine codes and do not correctly apply the counseling administration codes.

4. AAPC and CPT® Coding Guidelines:

According to AAPC guidelines, 90460 and 90461 are the appropriate administration codes for vaccines with counseling provided to pediatric patients, with each component of a multi-component vaccine coded separately.

Therefore, the correct answer is C. 90460 x 2, 90461 x 3, 90710, 90744.

Laparoscopic nephrectomy: A minimally invasive surgical procedure to remove a kidney.

Part of the ureter: Removal includes part of the ureter.

50220: Nephrectomy (open procedure), which doesn't apply since the procedure was laparoscopic.

50548: Nephrectomy, partial, laparoscopic, which doesn't match the full nephrectomy performed.

50543: Laparoscopy, surgical; nephrectomy with total ureterectomy.

50543 is the correct CPT code for the laparoscopic removal of the kidney along with part of the ureter, fitting the scenario described.

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

The procedure performed is a bilateral screening mammogram with computer-aided detection (CAD). CPT code 77067 is for bilateral screening mammography with CAD. ICD-10-CM code Z12.31 is for an encounter for screening mammogram for malignant neoplasm of the breast. Z80.3 is for a family history of malignant neoplasm of the breast. Therefore, the correct coding is 77067, Z12.31, Z80.3. References: CPT® Professional Edition (current year), ICD-10-CM (current year).

Cholecyst- = gallbladder

Entero- = intestine

-ostomy = creation of an opening

Cholecystenterostomy is the correct term for surgically creating a connection between the gallbladder and the intestine.

This aligns with surgical terminology commonly tested in the CPT® digestive system section (40000–49999).

1. E/M Service Code Selection:

On day two, the urologist provided an evaluation and management (E/M) service for a hospitalized patient with a low level for the number and complexity of problems addressed, minimal complexity for data reviewed, and moderate risk of complications.

CPT® Code 99232 is for a subsequent hospital care E/M service with a level of "Expanded Problem Focused" history and examination, with Medical Decision Making (MDM) of Moderate complexity. This matches the description provided, as the MDM includes a low number of problems, minimal data, and moderate risk.

2. Rationale for Excluding Other Options:

Code 99233 is for a subsequent hospital care visit with high complexity MDM (e.g., addressing a high number of problems or higher levels of data review), which does not align with the moderate risk described here.

Code 99221 is for initial hospital care, not a subsequent visit.

Code 99231 represents a lower level of subsequent hospital care with straightforward or low complexity MDM, which does not meet the moderate risk criteria in this scenario.

3. AAPC and CPT® Coding Guidelines:

AAPC and CPT® guidelines indicate 99232 as appropriate for subsequent hospital visits with moderate MDM, such as this visit with moderate risk but minimal data complexity.

Therefore, the correct answer is B. 99232.

Open Roux-en-Y Gastric Bypass: The procedure involves creating a small gastric pouch and anastomosing it to the jejunum.

CPT Code 43847: This code describes a surgical gastric restrictive procedure with gastric bypass for morbid obesity, open.

ICD-10-CM Code E66.01: This code represents morbid (severe) obesity due to excess calories.

ICD-10-CM Code Z68.42: This code indicates a BMI of 45.

Procedure Coding (CPT®):

69910 – Labyrinthectomy, complete; transmastoid approach

Provider performed:

Mastoidectomy

Complete destruction/removal of semicircular canals, utricle, and saccule

This is a complete labyrinthectomy, not partial

69990 – Microsurgical techniques, requiring use of operating microscope

Separately reportable with otologic procedures

Modifier -51 not required (add-on code)

Diagnosis Coding (ICD-10-CM):

H81.391 – Peripheral vertigo, right ear

Correct laterality and condition

Why Other Options Are Incorrect:

69905 – Partial labyrinthectomy

R42 – Symptom code (dizziness), not used when definitive diagnosis exists

Procedure: Visual field examination of both eyes using Goldmann perimeter testing with four isopters.

CPT® Code:

92082: This code is for visual field examination with intermediate examination.

ICD-10-CM Code:

G43.009: Migraine without aura, not intractable, without status migrainosus.

Code Selection Justification: The visual field exam method and complexity align with 92082. The patient's diagnosis of non-intractable migraine without aura is coded as G43.009.

ICD-10-CM (current year)

For initial fracture care of a closed scaphoid fracture, code 25622 is used, which includes treatment and initial casting. The application of the cast is part of the fracture care and is not reported separately. CPT® guidelines specify that casting or strapping performed as part of the fracture care is included in the fracture care code.
