A patient needs to have an oncology biochemical assay of five proteins performed to assess for ovarian cancer. These proteins include CA-125, apolipoprotein A1, beta-2 microglobulin, transferring, and pre-albumin.
Explanation
Answer: B - 81502 is the correct code for ovarian oncology biochemical assay of five proteins, including CA-125, apolipoprotein A1, beta-2 microglobulin, transferring, and pre-albumin.
Code 81500 is incorrect because, although this code is for ovarian oncology, it is only assessing two proteins, which include CA-125 and HE4. Code 81504 is incorrect because this code is for oncology of a specific tissue of origin, including a microarray gene expressing profiling. Code 81506 is incorrect because this code is specific for an endocrinology biochemical assay.
