The Certified Professional Coder (CPC) Exam (CPC)

1. Procedure and CPT® Code Selection:

The patient received IV hydration therapy with normal saline, which lasted for 1 hour and 30 minutes.

CPT® Code 96360 is used for initial IV hydration for the first hour. This code applies to the first 31-60 minutes of hydration therapy.

CPT® Code 96361 is used for each additional hour of IV hydration. Since the hydration lasted 1 hour and 30 minutes, 96361 should be reported once to cover the additional 30 minutes after the initial hour.

2. Rationale for Excluding Other Options:

Code 96365 is for initial IV infusion for therapeutic, prophylactic, or diagnostic purposes, rather than hydration, and is not applicable in this case.

Code 96366 is used for additional therapeutic, prophylactic, or diagnostic infusions and does not apply to hydration services.

Option A (96360) would only cover the initial hour of hydration, missing the additional 30 minutes, which is appropriately coded with 96361.

3. AAPC and CPT® Coding Guidelines:

According to AAPC and CPT® guidelines, 96360 should be used for the first hour of IV hydration, and 96361 should be used for each additional hour or portion of an hour beyond the initial 60 minutes.

Therefore, the correct answer is D. 96360, 96361.

The anesthesia code for an axillary block for procedures on the upper arm and elbow, which includes the monitoring by the anesthesiologist throughout the procedure, is 01830. This code is appropriate for anesthesia for all procedures on nerves, muscles, tendons, fascia, and bursae of the shoulder and axilla.

Anesthesia Coding Guidelines

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.

C2617 – Sinus implant, drug-eluting

Described implant:

Ethmoid sinus

Drug-eluting (corticosteroid)

Absorbable

Why others are incorrect:

C1877 – Vascular stent

S1091 – Temporary code

C9600 – Coronary intervention

P1–P6 = ASA Physical Status modifiers

AA, QS are anesthesia service modifiers

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.

Newborn circumcision coding depends primarily on whether the circumcision is performed using aclamp/device techniqueversus asurgical excision technique. CPT54150is commonly associated with circumcision using a clamp or other device method (often described with a Gomco/Mogen-type approach in many training contexts). In contrast, CPT54160representssurgical circumcisionusing acircumferential incisionwith excision of the foreskin—matching the documentation (“circumferential incision… foreskin excised with a scalpel”). The infant’s age (8 days old) supports that this is a newborn service, but the decisive factor in this vignette is thetechnique described. Modifier-52(reduced services) is not supported because the full circumcision service is performed. Modifier-63applies to procedures performed on infants less than 4 kg for certain CPT codes when applicable, but it is not universally appended and is not the best answer here given typical CPC exam expectations for standard newborn circumcision technique identification. Therefore,54160is correct.

“Nephr/o” is the combining form meaningkidney, and “-logy” meansstudy of. Therefore,nephrologyis the medical specialty focused on the kidneys—normal kidney function, kidney diseases, and their medical management. In CPC-style terminology questions, look for the body-system root first (nephr = kidney) and then confirm the suffix. This differs fromurology, which is a surgical specialty addressing the urinary tract and male reproductive system. Endocrinology relates to hormones and glands, neurology relates to the nervous system, and cardiology relates to the heart. A quick word-building check helps avoid distractors: nephrology = kidney; cardiology = heart; neurology = nerves/brain; endocrinology = endocrine glands. On the CPC exam, recognizing common combining forms (nephr/o, ren/o) and suffix patterns (-logy, -itis, -ectomy) is a frequent testing strategy, so anchoring on “nephr” reliably identifies the correct specialty.

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.
