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 the injections, CPT® code 64642 is used for chemodenervation of one extremity; 64643 for each additional extremity, and 64647 for chemodenervation of muscles in the paraspinal region. The modifier -50 is added to 64642 and 64643 to indicate bilateral procedures. According to CPT® guidelines, when multiple sites are treated, each site is coded separately, and appropriate modifiers are used.

The documented study is atransvaginal pelvic ultrasound, which is coded with76830(ultrasound, transvaginal). Because the service is billed by anindependent radiologist providing only the interpretation, the correct reporting is theprofessional componentwith modifier-26(interpretation and report), not the global code. That makes76830-26the correct CPT selection. Code76817is fortransvaginal ultrasound in pregnancy/obstetric contexts, which is not supported here (the patient is menopausal and no pregnancy evaluation is described). For diagnosis, the chief complaint isuterine cramping, and the options provide pelvic pain codes;N94.89(other specified conditions associated with female genital organs and menstrual cycle) is the best match among the choices provided for uterine cramping/pelvic symptom documentation.N94.9is less specific (“unspecified”), so when a more specific option is available in the answer set, selectN94.89. Therefore, the correct combination for the interpreting independent radiologist is76830-26, N94.89.

Diabetes mellitus is achronic illness. In the MDM framework, the “number and complexity of problems addressed” considers whether a chronic condition isstable, whether it isexacerbated, and whether it requires significant management changes. The vignette says this is afollow-upfor diabetes with blood sugarsat goaland continuing current medications—this describes astable chronic illnessbeing managed. It is not an acute illness or injury, and it is not “minimal problem,” because diabetes generally requires ongoing monitoring and management and is not considered trivial. “Stable, acute illness” is internally inconsistent; “acute uncomplicated illness/injury” is also incorrect because diabetes is not acute in this context. CPC exam tip: “stable on meds” + chronic disease follow-up →stable chronic illness(often supporting at least a low-to-moderate problem complexity depending on other MDM elements). Therefore, the correct selection isStable, chronic illness.

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.

1. Procedure and CPT® Code Selection:

The obstetric panel ordered includes the following tests: syphilis screening (non-treponemal), automated CBC with manual differential WBC count, HBsAg, rubella antibody, serum antibody screen, and ABO/Rh blood typing.

CPT® Code 80055 is for a comprehensive obstetric panel that includes all these components. This code is intended to report the entire panel of tests as a bundled service rather than itemizing each individual test.

2. Rationale for Excluding Other Options:

Option B lists the individual component codes for each test in the obstetric panel (e.g., 85027, 85007, 87340, etc.), but using 80055 is more appropriate because it provides a single code to report the full obstetric panel and follows CPT® bundling guidelines.

Option C also lists the individual tests separately, which is unnecessary when 80055 includes all these components.

Option D lists 80081, which is for an obstetric panel that includes HIV testing. Since HIV testing is not part of the tests described in this scenario, 80081 is incorrect.

3. AAPC and CPT® Coding Guidelines:

AAPC guidelines recommend using the single code 80055 when all components of an obstetric panel are ordered together, as itemizing each test individually is not necessary.

Therefore, the correct answer is A. 80055.

TSH testing is reported with CPT84443. The scenario describes a workup for possible thyroid dysfunction, but there isno confirmed thyroid diagnosisprovided—only symptoms (fatigue and weight gain). In outpatient coding, when a definitive diagnosis is not established, you code thesigns/symptomsthat justify the test. Therefore, the correct ICD-10-CM codes areR53.83(other fatigue) andR63.5(abnormal weight gain), as offered. You shouldnotassign a thyroid disorder code such asE07.9(unspecified disorder of thyroid) unless the provider documents an actual thyroid disorder diagnosis; suspicion alone does not support it in the outpatient setting. Options C and D list84445, which is not the standard CPT code for TSH measurement in CPC exam coding. This question is testing both correct lab code selection and the outpatient guideline principle of codingsymptomswhen the diagnosis is not confirmed. Hence,84443 with R53.83 and R63.5is correct.

Per ICD-10-CM guidelines, when dependence is documented with either use or abuse, only the dependence code is assigned, as it takes precedence.

For a complete bilateral mastectomy with insertion of breast prosthesis performed during the same surgical session, the correct CPT® codes are:

1. 19303-50: This code represents a complete mastectomy (removal of breast tissue) performed bilaterally (indicated by the -50 modifier).

2. 19340-50: This code is for the immediate insertion of a breast prosthesis following mastectomy, also performed bilaterally.

Explanation of other options:

A. 19303-50, 19342-50: Incorrect because 19342 is for the insertion of a breast implant, which differs from a prosthesis.

B. 19305-50, 19340-50: 19305 describes a modified radical mastectomy, which is more extensive than what is documented here.

C. 19325-50: This code represents a breast augmentation procedure, not a mastectomy with prosthesis insertion.

Thus, the correct answer is D. 19303-50, 19340-50, which accurately describes a bilateral mastectomy with prosthesis insertion.

Medical terms often consist of a root word and a suffix.

Hepat/o = liver

-itis = inflammation

Therefore, hepatitis literally means inflammation of the liver.

The incorrect options refer to inflammation of other body parts:

Dermatitis – inflammation of the skin

Gastritis – inflammation of the stomach

Arthritis – inflammation of the joints

Hence, the correct answer is C. Hepatitis.
