AAPC CPC Exam Dumps

Procedure Coding (CPT):

33533 -- CABG, arterial graft; single arterial graft (LIMA to LAD)

Correct for left internal mammary artery LAD

33519 -- CABG, venous grafts; three coronary venous grafts

Saphenous vein grafts placed to:

Obtuse marginal

Ramus intermedius

Posterior descending artery

Total = 3 venous grafts

33508 -- Endoscopic harvest of saphenous vein

Separately reportable only when endoscopic

Add-on code (no modifier required)

Why Other Options Are Incorrect:

A / C -- Incorrect arterial graft code (33536 = multiple arterial grafts)

B -- Incorrect venous graft count (33512 = two grafts)

CPT Guideline Reference:

CABG codes are selected based on:

Type of conduit (arterial vs venous)

Number of distal anastomoses

Endoscopic harvest is add-on and separately reportable

1. Procedure and CPT Code Selection:

The patient requires a surgical nasal sinus endoscopy to repair a cerebrospinal fluid (CSF) leak caused by a skull fracture that resulted in CSF draining into the nasal passage.

Code 31291 is the correct CPT code for an endoscopic repair of a cerebrospinal fluid leak in the sphenoid sinus. This procedure code is appropriate because it specifically addresses surgical endoscopy for CSF leak repair in the sinus region.

Other codes provided, such as 31287 (nasal/sinus endoscopy with balloon dilation) and 31235 (nasal endoscopy with biopsy), do not match the description for surgical repair of a CSF leak and are therefore inappropriate for this case.

2. Diagnosis and ICD-10-CM Code Selection:

ICD-10-CM Code S02.19XA is used to describe a fracture of the anterior cranial base, which fits the described injury of the skull with cerebrospinal fluid leakage.

External cause code V47.5XXA is used for motor vehicle accidents involving a car hitting a stationary object.

Y92.411 is the appropriate code to describe the location of the accident as a highway.

3. Exclusion of Additional Procedure Codes:

There is no need for a second endoscopy code or a modifier, as 31291 fully describes the endoscopic repair procedure for the CSF leak.

4. AAPC and CPT Coding Guidelines:

Per AAPC guidelines, procedure codes for sinus endoscopy are chosen based on the specific type of intervention (e.g., CSF leak repair). The guidelines for ICD-10-CM stress including external cause codes and location codes for trauma cases related to motor vehicle accidents.

Thus, the correct answer based on CPT and ICD-10-CM coding standards is B. 31291, S02.19XA, V47.5XXA, Y92.411.

1. Procedure and CPT Code Selection:

The obstetric panel ordered includes the following tests: syphilis screening (non-treponemal), automated CBC with manual differential WBC count, HBsAg, rubella antibody, serum antibody screen, and ABO/Rh blood typing.

CPT Code 80055 is for a comprehensive obstetric panel that includes all these components. This code is intended to report the entire panel of tests as a bundled service rather than itemizing each individual test.

2. Rationale for Excluding Other Options:

Option B lists the individual component codes for each test in the obstetric panel (e.g., 85027, 85007, 87340, etc.), but using 80055 is more appropriate because it provides a single code to report the full obstetric panel and follows CPT bundling guidelines.

Option C also lists the individual tests separately, which is unnecessary when 80055 includes all these components.

Option D lists 80081, which is for an obstetric panel that includes HIV testing. Since HIV testing is not part of the tests described in this scenario, 80081 is incorrect.

3. AAPC and CPT Coding Guidelines:

AAPC guidelines recommend using the single code 80055 when all components of an obstetric panel are ordered together, as itemizing each test individually is not necessary.

Therefore, the correct answer is A. 80055.

The CABG procedure involved multiple bypasses, with the use of autologous saphenous vein grafts and the left internal mammary artery, along with an extensive modified MAZE procedure. CPT code 33535 describes a coronary artery bypass using arterial grafts, including at least three coronary artery bypasses. CPT code 33259-51 is for the MAZE procedure for supraventricular tachycardia, with the -51 modifier indicating multiple procedures. CPT code 33519-51 is for an additional vein graft, and CPT code 33508-51 describes the endoscopic harvesting of the vein.

AMA's CPT Professional Edition (current year), Codes 33535, 33259-51, 33519-51, 33508-51

Esotropia of the right eye: Indicates strabismus surgery is required.

Resection of medial rectus horizontal and lateral rectus muscles: Specific muscles addressed during the surgery.

Adjustable sutures: Used in securing the muscles, indicating specific techniques.

Extensive scar tissue from previous surgery: Requires additional work and isolation.

CPT codes 67314 and 67334 are used to report the resection of two muscles with adjustable sutures (67314) and surgery on an extraocular muscle involving extensive scar tissue (67334).
