Certified Professional Coder (CPC)

Procedure and Code Selection: The procedure performed is a percutaneous needle biopsy of the liver with CT guidance. CPT 47000 accurately represents a percutaneous liver biopsy and includes all biopsy passes performed during the same session; therefore, obtaining multiple core samples does not warrant additional biopsy codes.

CT imaging guidance for needle placement is separately reportable using CPT 77012. This code specifically describes CT guidance for needle placement and is appropriate when CT is used to localize and guide the biopsy.

Exclusion of Other Codes: CPT 47001 is an add-on code used only when a liver biopsy is performed in conjunction with another primary surgical procedure (e.g., open or laparoscopic surgery). It is not applicable to a standalone percutaneous biopsy.

CPT 76942 represents ultrasound guidance for needle placement and is not appropriate when CT guidance is documented.

CPT 77002 represents fluoroscopic guidance and is likewise incorrect when CT guidance is used.

Coding Guidelines:
According to CPT and AAPC guidelines, imaging guidance for needle placement may be reported separately when it is not inherently included in the primary procedure and when properly documented. CPT 47000 does not include imaging guidance; therefore, CPT 77012 is appropriately reported in addition.

Final Answer:
47000, 77012

Spirometry performed before and after bronchodilator is coded with 94060. That code includes the pre-and post-bronchodilator spirometry components as a single bundled service, so it already captures the "before and after" testing. The scenario also lists measurements such as flow-volume loops, but the defining element for coding is the bronchodilator responsiveness testing captured by 94060. For diagnosis, "intermittent asthma with exacerbation" maps to J45.21, mild intermittent asthma with acute exacerbation.
Code J45.901 represents unspecified asthma with acute exacerbation and is not as specific as the documented intermittent asthma. Options using 94070 do not represent spirometry pre-and post- bronchodilator testing; they are different pulmonary testing codes. CPC exam focus: choose the most
specific asthma diagnosis available and recognize that 94060 already includes the pre-and post-bronchodilator testing, so adding a separate basic spirometry code in the same session is not appropriate.
Therefore, the correct answer is B. 94060, J45.21.

J2405 = Ondansetron hydrochloride, per 1 mg.
The patient received 2 mg, so report J2405 x 2.

J1885 = Ketorolac tromethamine, per 15 mg.
The patient received 15 mg, so report J1885 once.

Therefore, the correct answer is B. J2405 x 2, J1885.

Omalizumab is a drug reported with HCPCS J2357, and the dose is converted into billable units based on the code's unit definition. In CPC-style questions, 150 mg is commonly represented as J2357 x 30 units.
Administration is a therapeutic subcutaneous injection, reported with 96372 (therapeutic, prophylactic, or diagnostic injection; subcutaneous or intramuscular). Vaccine administration codes (90460/90471) are not
appropriate because omalizumab is not a vaccine. For diagnosis, the statement includes status asthmaticus but does not specify severity category. In the options provided, J45.902 represents unspecified asthma with status asthmaticus, whereas J45.52 requires severe persistent asthma with status asthmaticus, which is not documented.
Therefore, the correct pairing is 96372, J2357 x 30, and J45.902.
CPC exam tip: Match the administration code type, therapeutic injection vs. immunization, and choose the most specific ICD-10-CM code supported by documentation.
