59 modifier would be used to distinguish between the services of CPT code 87480 and 87481. If direct probe technique was used for infectious agent detection of Candida species and along with that if amplified probe technique was also used for infectious agent detection of Candida species, we can bill both these codes together by appending modifier 59 to CPT code 87481 to distinguish between the services. One service is by the direct probe technique and the other service is by the amplified probe technique.
91 modifier should be appended when it is necessary to repeat the same laboratory test on the same day to obtain subsequent (multiple) test results. Under these circumstances, the laboratory test performed can be identified by its usual procedure number and the addition of modifier 91.
In the above mentioned scenario, bill 59 modifier with CPT code 87481 to distinguish it from the services of CPT code 87480. If any particular test has been repeatedly performed, then bill that CPT code with 91 modifier.
