CPC Exam Dumps : Certified Professional Coder (CPC) Exam

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 clinical scenario involves a diagnostic angiography (not separately reportable in this case as the therapeutic intervention occurs in the same session and the diagnosis is already known) and a percutaneous transluminal angioplasty (PTA) with stent placement in the left iliac artery.

To code this correctly:

CPT Code 37267: Transluminal stent placement(s), includes angioplasty within the same vessel, when performed; iliac artery.

This code includes the angioplasty if it is performed in the same vessel as the stent (which is true here — both procedures are done in the left iliac artery).

Since angioplasty is inherent to the stenting (to open the narrowed vessel before stent placement), only the stent code is reported.

No need to report angioplasty separately (e.g., 37263) when performed in the same vessel as the stent.

Other options explained:

A. 37267, 37263 – Incorrect. 37263 (angioplasty in the iliac artery) would only be reported if angioplasty was done in a separate iliac artery segment without stenting. Reporting both codes for the same vessel would be unbundling and against CPT/NCCI guidelines.

B. 37258, 37254 – Incorrect. These codes relate to renal artery procedures, not iliac artery.

C. 37258 – Also incorrect, as this refers to renal stent placement, not iliac.

Official CPT® Guideline Reference:

In the CPT® manual (Category I codes, 37220–37235), specific instructions state that angioplasty is included when performed in the same vessel as a stent and should not be reported separately.

Burn coding requires (1) code each burn site bylocation, laterality, and degree, and (2) add aTBSAcode when appropriate. The patient hasthird-degree burnsof both thighs (right and left), so the correct site/degree codes areT24.311A(third-degree burn of right thigh, initial encounter) andT24.312A(third-degree burn of left thigh, initial encounter). He also hassecond-degree burnsof the right anterior chest wall and the upper back, reported withT21.21XA(second-degree burn of chest wall, initial encounter) andT21.23XA(second-degree burn of back wall, initial encounter). TBSA is24%(falls in the 20–29% category), andthird-degree is 10%(falls in the 10–19% third-degree category), so the correct TBSA code isT31.21. Option D matches the required site/degree codes and the correct TBSA/third-degree percentage code pairing.
