What 00147 covers
This service covers anesthesia for an operative procedure on the iris in which tissue is removed, such as an iridectomy performed as part of eye surgery. An anesthesiologist or CRNA reports the anesthesia service; the ophthalmologist reports the eye operation separately. The operative record identifies the iris procedure, while the anesthesia record documents the care provided and anesthesia start and end times.
Choose 00147 for anesthesia when the operation is an iridectomy, not for lens surgery, corneal transplantation, vitreoretinal surgery, eyelid reconstruction, or ophthalmoscopy. The record should support the specific iris operation and the anesthesia practitioner’s service. This code has 4 base units; Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor. Anesthesia time is measured in minutes from when the anesthesia practitioner begins preparing the patient for anesthesia until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care, then converted to 15-minute time units to one decimal place; the conversion factor varies by locality.

00147 billing questions
When should anesthesia be reported with 00147 instead of 00140?
Use 00147 when the operative procedure is an iridectomy involving removal of iris tissue. Code 00140 is for other eye procedures not more specifically represented by a procedure-specific anesthesia code.
Is 00147 the code for the iridectomy itself?
No. It represents the anesthesia service; the ophthalmologist reports the operation using the applicable surgical code.
How are anesthesia units calculated for 00147?
The code has 4 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, and multiplies the total by the locality’s anesthesia conversion factor.
What documentation supports reporting 00147?
The operative record should identify the iridectomy, and the anesthesia record should document the anesthesia service and its start and end times.
Does 00147 apply to laser iridotomy?
00147 describes anesthesia for an iridectomy. Do not select it solely because an eye procedure involves the iris; confirm that the documented operation is an iridectomy.
