AAPC CPC - Certified Professional Coder (CPC) Exam

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).

73522 = Bilateral hips with pelvis, 3–4 views

Modifier -76 = Repeat procedure by the same physician

Modifier -51 identifies multiple procedures

When hypertension and heart disease are documented together, a cause-and-effect relationship is presumed unless stated otherwise.

Category I11 (Hypertensive heart disease) is used.

Additional codes from I50.- (heart failure) are assigned if applicable.

This follows ICD-10-CM Official Coding Guidelines.

The correct ICD-10-CM coding for this patient is B20, M54.50. The first code, B20, is used for HIV disease, which is a confirmed diagnosis of HIV infection. It’s important to note that this code can be used regardless of whether the patient is symptomatic or asymptomatic, as long as the patient has been diagnosed with HIV.

The second code, M54.50, refers to low back pain, which would be used to report the loin pain described by the patient. " Loin pain " typically refers to pain in the lower back area, and this code specifically covers the general category of low back pain not otherwise specified.

The other options are not as accurate:

A (B20, M54.9) includes a nonspecific code for back pain (M54.9), which does not fully specify the pain’s location.

B (M54.51, B20) incorrectly includes a code for thoracic or lumbar radiculopathy (M54.51), which is not indicated here.

D (M54.50, B20) is similar to the correct answer, but it incorrectly lists the codes in reverse order. It is important to list the HIV diagnosis first in ICD-10-CM.

For Mohs micrographic surgery, CPT® coding is based on the anatomic location of the lesion, the number of stages, and the number of tissue blocks per stage.

17311: This code is used for Mohs surgery on body areas such as the trunk, arms, or legs for the first stage.

17315: This is an add-on code used when more than five tissue blocks are examined in a single stage. Since this case involved six tissue blocks, 17315 is appropriate.

Explanation of incorrect answers:

A. 17313, 17314, 17315: Incorrect, as 17313 applies to the head, neck, hands, feet, or genitalia, not the arm.

C. 17313, 17315: Incorrect, as 17313 is not appropriate for the arm.

D. 17311, 17312, 17315: 17312 is used for additional stages beyond the first, which is not applicable here since only one stage was performed.

E. 85B2-335 is not a valid CPT code for Mohs surgery.

Thus, the correct answer is B. 17311, 17315, which accurately reflects a single-stage Mohs surgery with six tissue blocks on the arm.

To code for anesthesia services, we select the correct CPT® anesthesia code based on the procedure, modifiers, and physical status of the patient:

00800 represents " Anesthesia for procedures on the lower abdomen not otherwise specified, " which includes procedures like a panniculectomy. The code 00802 is not appropriate here because it is used for lower abdominal procedures involving " major lower abdominal vessels, " which does not apply to a panniculectomy.

AA Modifier indicates that the anesthesia services were personally performed by the anesthesiologist, as stated in the scenario.

P3 Modifier reflects a physical status of 3, which indicates a patient with a " severe systemic disease, " matching the patient ' s documented condition.

The emergency modifier 99140 is not appropriate here, as there is no indication that the procedure was performed under emergency conditions.

Thus, the correct answer is 00800-AA-P3.

Complex (arm, 4 cm) → 13121

Intermediate legs total = 20.5 cm → 12036

Simple face closures coded separately:

12013 (cheek)

12011 (nose)

Modifiers allow separate anatomical reporting.

Correct answer: A

Anesthesia CPT®:

00120 – Anesthesia for ear procedures

AD modifier:

Anesthesiologist medically directing > 4 CRNAs

P3 – Severe systemic disease

Diagnosis Code:

H90.41 – Sensorineural hearing loss, unilateral, right ear

Why others are incorrect:

AA – Personally performed

QX / QY – Incorrect direction model

H90.5 – Unspecified hearing loss

Fascia debridement → 11043 (first 20 sq cm)

Subcutaneous debridement → 11042

Multiple anatomical sites → Modifier -59

Add-on code 11045 for additional subcutaneous surface area

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.
