The epididymis is a structure attached to the testes that stores and transports sperm.

It is part of the male reproductive system, not the urinary system.

This concept falls under anatomy and physiology, a core CPC exam domain.

The procedure documented is a modified Fontan procedure → 33615 (Fontan-type single-ventricle repair per the choices given).

The congenital diagnosis documented is double inlet ventricle → Q20.2.

Why the other options are incorrect based on the statements provided:

Q20.4 is not “double inlet ventricle” as stated in the question.

Adding Q20.1 is not supported by the documentation (the question only states double inlet ventricle).

Therefore, the best match is 33615, Q20.2 → A.

69209-RT – Removal of impacted cerumen using irrigation

69210-LT – Removal of impacted cerumen using instrumentation

Coding Rules Applied:

Different techniques → different CPT codes

Different ears → RT/LT modifiers, not modifier -50

Why Other Options Are Incorrect:

A – Modifiers reversed

B / D – Modifier -50 inappropriate when different CPT codes are used

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)

When hypertension and chronic kidney disease (CKD) are documented together, ICD-10-CM assumes a cause-and-effect relationship.

I12.9 = Hypertensive chronic kidney disease with stage 1–4 CKD

N18.2 = CKD stage 2

I12.0 is only for CKD stage 5 or ESRD, which does not apply here.

Therefore, the correct code combination is I12.9, N18.2.

Procedure Coding:

49186 – Excision or destruction of intra-abdominal tumors, 1–4 tumors

Four tumors excised → correct code selection

Size does not alter code selection once tumor count is determined

Diagnosis Coding:

C48.2 – Malignant neoplasm of peritoneum, unspecified

Pathology confirms malignancy

C76.2 is used for ill-defined sites, not appropriate when peritoneum is specified

Why Other Options Are Incorrect:

B – 49187 is for 5 or more tumors

D – K66.8 = non-malignant peritoneal disorder

Diabetic polyneuropathy is coded as E11.42, which indicates type 2 diabetes mellitus with diabetic polyneuropathy. The ICD-10-CM guidelines direct that when a patient has both diabetes and polyneuropathy, a single combination code is used to capture both conditions.

ICD-10-CM (current year), Chapter 4: Endocrine, Nutritional, and Metabolic Diseases (E00-E89), ICD-10-CM Official Guidelines for Coding and Reporting, Section I.C.4.a.6.

Procedure Coding:

56633 – Radical vulvectomy (removal of >80%), including deep subcutaneous tissue

Documentation supports greater than 80% vulvar removal

Deep tissue involvement confirms radical procedure

Diagnosis Coding:

D07.1 – Carcinoma in situ of vulva

VIN III = high-grade squamous intraepithelial lesion

Classified as carcinoma in situ, not benign dysplasia

Why Other Options Are Incorrect:

56620 / 56625 / 56630 – Partial or simple vulvectomy

N90.1 – Mild vulvar dysplasia (incorrect severity)

ICD-10-CM Official Guideline:

VIN III is coded as D07.1, not N90.x.

Lesion excision codes in the CPT® codebook include the removal of the lesion along with the necessary margins and a simple (nonlayered) closure when performed. These codes do not cover intermediate or complex closures, which are reported separately if performed. The measurement for selecting the appropriate lesion excision code includes the lesion and the margins required for complete excision.

AMA's CPT® Professional Edition, lesion excision guidelines.

The scenario involves a secondary repair of two flexor tendons in the forearm. CPT® code 25272 describes the repair of a secondary flexor tendon injury, including a graft, in the forearm and/or wrist, which fits the description provided. This code should be reported once, as the procedure encompasses the repair of multiple tendons.
