CPC Exam Dumps : Certified Professional Coder (CPC) Exam

A sphincter is a muscular ring that encircles a lumen (or passage) and contracts to control the flow of substances through it. Sphincters are found throughout the body in areas such as the gastrointestinal tract (e.g., the lower esophageal sphincter, pyloric sphincter, anal sphincter) and the urinary system (e.g., urethral sphincter), where they regulate the passage of food, waste, and other materials.

A. Stricture refers to an abnormal narrowing of a passage or duct in the body, often due to scarring or disease, not a muscular ring.

B. Snare is a surgical instrument, not a structure within the body.

D. Sinus refers to a cavity or channel within bone or tissue, unrelated to muscle control of flow.

Therefore, the correct answer is C. Sphincter.

49083 – Abdominal paracentesis, diagnostic or therapeutic; with imaging guidance

This code includes imaging guidance (ultrasound or fluoroscopy).

Per CPT® guidelines, do not separately report fluoroscopy or ultrasound guidance with 49083.

The procedure was performed in the hospital, but CPT coding does not change based on site of service.

Why Other Options Are Incorrect:

A (49082) – Used without imaging guidance

B / D – Imaging guidance codes (77001, 77002) are bundled into 49083 per CPT® and NCCI edits

Official CPT® Guidance:

When a paracentesis is performed with imaging guidance, report 49083 only.

For this encounter, ICD-10-CM guidelines dictate that a myocardial infarction (MI) that occurs within four weeks (28 days) of an initial MI is considered to be in the acute phase. Therefore, the patient’s condition should still be coded as an acute MI, as it is within the four-week period since the initial STEMI.

B. I21.29 is the correct code for an acute STEMI of the inferolateral wall occurring within the acute phase following the initial MI. The code I21.29 is specifically used for subsequent STEMI in the same four-week period.

Explanation of incorrect options:

A. I22.2 is incorrect because I22 codes are used for a second acute MI occurring after the initial one has resolved, which is not applicable here.

C. I21.19 and D. I21.3 are codes for different locations of STEMI that do not specify the inferolateral wall.

Therefore, the correct answer is B. I21.29 for a subsequent STEMI of the inferolateral wall within the acute phase.
