A patient’s physician has had a hard time finding the correct drug to put the patient on. Thinking that it has to do with the way the patient’s body metabolizes the drug, she orders a CYP2C19 gene analysis. What is the correct CPT code for this test?

81220
81225
81226
81227

Explanation

Answer: B - 81225 is the correct code for the CYP2C19 gene analysis test.

Code 81220 is incorrect because this code is for CFTR gene analysis. Code 81226 is incorrect because this code is for CYP2D6 gene analysis and code 81227 is incorrect because this code is for CYP2C9 gene analysis.
