CPT code 00142: Lens surgery anesthesia, lens procedures2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 00142 in California.

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

What 00142 covers

Code 00142 applies to anesthesia for operations on the crystalline lens, most commonly cataract removal with placement of an intraocular lens. Anesthesia professionals provide the service in hospital operating rooms and ambulatory surgery centers, supporting ophthalmic surgeons during procedures involving lens access and manipulation. The anesthesia claim represents the professional anesthesia service, not the surgeon’s lens procedure.

Use this code when the operative plan centers on lens surgery; other eye operations, such as corneal transplantation or vitreoretinal surgery, have separate anesthesia categories. The operative report should identify the lens procedure, and the anesthesia record should establish the practitioner’s service and start and stop times. Code 00142 has 4 base units; Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor, which varies by locality. Time is reported in minutes and converted to 15-minute units to one decimal place, from preparation for anesthesia until personal attendance ends and the patient can safely be placed in postoperative care.
