CPT code 00147: Iridectomy anesthesia, iris surgery2026 Medicare rate & RVUs in Texas

CMS doesn’t publish an office rate for 00147 in Texas.

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

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.
