When billing for a 3 hour glucose tolerance, is it appropriate to bill for 3 veniunctures if it is actually done 3 times, and not a catheter left in place?

The rarely used intravenous glucose tolerance test (IGTT) involves glucose being injected into the patient's vein for 3 minutes. The lab personnel measures blood insulin levels before the injection, and at 1 and 3 minutes thereafter.
Providers should report only one venipuncture procedure for glucose tolerance tests even though multiple blood draws are performed.
