Due to a previous child having some fetal congenital abnormalities, the OB/GYN ordered a biochemical assay of four analytes (AFP, uE3, hCG, DIA) to assess for fetal congenital abnormalities of pregnancy #3. This is done by using the mother’s blood and is reported with a risk score for the provider to interpret. What is the correct CPT code for this test?
Explanation
Answer: D - 81511 is the correct code for the test for fetal congenital abnormalities including AFP, uE3, hCG, and DIA.
Code 81508 is incorrect because this code is for the testing of the biochemical assay of two proteins (PAPP-A, hCG). Code 81509 is incorrect because it is also testing for proteins, but involves three proteins instead of just the two above. This code tests for PAPP-A, hCG, and DIA). Code 81510 is incorrect because this code is for the testing of three analytes, including AFP, uE3, hCG, but does not include the fourth analyte listed above, the DIA.
