CPT code 87635 is used to report laboratory testing for SARS-CoV-2 (the virus that causes COVID-19) using nucleic acid amplification techniques (NAAT), such as reverse transcription polymerase chain reaction (RT-PCR).
The following are some coding guidelines for CPT code 87635:
- The test should be ordered and performed for the diagnosis of COVID-19 or to confirm a suspected case of COVID-19.
- This code should only be used for testing that is performed using NAAT techniques.
- The code can be reported once for each individual test, even if multiple specimens are collected from the same patient on the same day.
- If the test is ordered as part of a panel of tests that includes other COVID-19 tests, such as antibody testing, each test should be reported separately using the appropriate code.
- When billing for this test, it is important to use the correct diagnosis code to indicate that the test was performed for COVID-19. The appropriate ICD-10 code for COVID-19 should be used, such as U07.1 for confirmed cases or Z20.822 for suspected cases.
It is important to note that coding guidelines may change over time, so it is always best to consult the latest coding resources and guidelines for accurate coding and billing practices.
