Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 01916 covers

This service supports catheter-based imaging that uses contrast to examine arteries or veins for findings such as narrowing, aneurysm, blockage, or impaired venous drainage. An anesthesiologist or CRNA may provide it in a hospital or imaging suite while a radiologist or interventional radiologist performs the vascular study. The anesthesia code represents the anesthesia practitioner’s service, not the imaging interpretation.

Choose this code for a diagnostic arteriography or venography examination, rather than anesthesia for a therapeutic vascular intervention. Cardiac catheterization and noninvasive imaging have separate anesthesia codes. The anesthesia record should identify the diagnostic vascular procedure and document the practitioner’s anesthesia time; the operative or imaging report should establish the vessels examined and diagnostic purpose. This code has 5 base units. Medicare payment is (5 base units + time units) × the locality’s anesthesia conversion factor. Time is measured from anesthesia preparation through the end of personal attendance when the patient can safely enter postoperative care, converted from minutes to 15-minute units to one decimal place; the conversion factor varies by locality.
