Question: How do we code for rapid influenza tests done in the office?
New Hampshire Subscriber
Answer: There is no CPT code for the influenza tests, recently waived under the Clinical Laboratory Improvement Act (CLIA). While waiting for a new code, expected in 2002, code 87899 (infectious agent detection by immunoassay with direct optical observation; not otherwise specified). If the payer is Medicaid, append HCPCS modifier -QW (CLIA waived test).
