Lab Tests Performed in Physician’s Offices When performing
laboratory tests in the physician’s office:
1. The Physician must be CLIA certified to perform the test,
2. The Physician must have the appropriate equipment to
perform the test, and
3. The Physician’s office bills for the tests performed but
not the collection fee.
When specimens are sent to an outside lab:
1. The Physician’s office should not bill the laboratory
code, and
2. The Physician’s office may bill a collection fee with a
“90” modifier for blood specimens
