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.

00142 billing questions
When should I choose 00142 instead of 00140?
Use 00142 when the operation is on the crystalline lens, such as cataract removal with lens implantation. Code 00140 is the general category for other eye procedures not classified more specifically.
How does 00142 differ from anesthesia for corneal or retinal surgery?
This code is for lens operations. Corneal transplantation and vitreoretinal surgery have distinct anesthesia categories, 00144 and 00145, respectively.
Is the surgeon’s cataract procedure included in the anesthesia claim?
No. The anesthesia claim represents the anesthesia professional’s service; the ophthalmic surgeon reports the operative service separately.
How are units calculated for 00142?
The code has 4 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, then applies the locality’s anesthesia conversion factor.
What should the records show?
The operative report should identify the lens operation, and the anesthesia record should support the anesthesia service and its start and stop times.
How does Medicare pay when an anesthesiologist medically directs a CRNA?
Medicare pays each practitioner 50% of the allowance for the personally performed service.
