AAPC Updated CPC Exam Questions and Answers by khalil

Atranstympanic(intratympanic) injection involves placing medication through the tympanic membrane into the middle ear space. CPT69801is used to report this transtympanic injection/tympanocentesis-type service as represented in CPC-style questions. Because the physician performed the injection inboth earsduring the same session, the appropriate bilateral reporting method in this answer set ismodifier -50to indicate abilateral procedure. Reporting69801 × 2is a common trap; many payers require either modifier 50 or RT/LT rather than two units, and the CPC exam typically follows modifier logic as presented in the options. Modifier-22(increased procedural services) would require unusual extra work beyond typical complexity and is not supported by the vignette. Reporting only a single unilateral code (option A) would underreport the bilateral nature. Therefore, the best answer is69801-50, reflecting the same service performed on paired organs during the same encounter.

“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.

47000 = Percutaneous liver biopsy

77021 = MRI guidance for needle placement

Multiple cores are included in the biopsy code

1. Procedure and CPT® Code Selection:

The patient underwent a thyroidectomy for malignancy in the right lobe, as well as the removal of the parathyroid gland due to a suspected malignant lesion.

CPT® Code 60505 is for the parathyroidectomy with exploration of parathyroid glands and is appropriate for the removal of the parathyroid gland due to a suspected malignancy.

CPT® Code 60220 represents a thyroid lobectomy (total removal of one lobe of the thyroid), which applies to the removal of the right thyroid lobe in this case.

2. Modifier 59:

Modifier 59 is added to 60220 to indicate that the thyroid lobectomy is a distinct procedure from the parathyroidectomy, performed in a separate anatomical site during the same surgical session.

3. Rationale for Excluding Other Options:

Code 60500 (in options A and C) is for a parathyroid exploration only, not including the actual removal of the parathyroid gland, so it does not apply here.

Code 60240 (in option D) is for a total thyroidectomy, which involves removal of the entire thyroid gland. Since only the right lobe was removed, 60220 (thyroid lobectomy) is correct.

4. AAPC and CPT® Coding Guidelines:

Per AAPC guidelines, 60505 is the appropriate code for parathyroidectomy procedures involving exploration or suspected malignancy, and 60220 with Modifier 59 accurately reflects the separate and distinct thyroid lobectomy procedure.

Thus, the correct answer is B. 60505, 60220-59.
