Strep Group Dictates PCR Test Codes

Question: How should we report the service when our lab tests for Strep group A and group B on a throat swab using an amplified probe technique?

Answer: You should report one code for each test as follows:

  • 87651 (Infectious agent detection by nucleic acid (DNA or RNA); Streptococcus, group A, amplified probe technique)
  • 87653 (… Streptococcus, group B, amplified probe technique).

Strep group B rarely causes “strep throat,” so it would be unusual for a clinician to order the polymerase chain reaction (PCR) test for both group A and group B. You might want to check with the clinician regarding the reason for the order, and check the payer’s coverage rules for the test.
