• How to Bill for Testing Glucose During Exam


    Question: We have a glucose monitor to check blood sugar during visits, when needed. I am unable to locate an allowable for this in the Medicare Part B fee schedule. Is there a specific code we should submit?

    Answer: The physician fee schedule does not include the allowable for this lab test. If you bill separately for it, make sure it is listed as an exempt lab test with the Clinical Laboratory Improvements Amendments of 1988. Even with CLIA exemption, not all payers allow physician offices to bill for a lab test considered part of the exam you've provided. Note that you will also be an outlier with this billing, since ophthalmologists do not commonly perform this test.
