What 00140 covers
Anesthesia for other eye procedures applies when the operation involves the eye but does not fit a more specifically classified anesthesia service. Anesthesiologists and CRNAs report it for anesthesia they provide for procedures such as strabismus surgery, commonly performed in a hospital or ambulatory surgery center. The operative service is reported separately by the surgeon.
Choose 00140 for qualifying eye procedures rather than anesthesia for lens surgery, corneal transplantation, vitreoretinal surgery, iridectomy, or ophthalmoscopy, which have their own codes. The operative report should identify the eye procedure and structures treated; the anesthesia record should support the service and its timing. This code has 5 base units; Medicare payment is (base units + time units) multiplied by the locality’s anesthesia conversion factor. Time is reported in minutes, converted to units of 15 minutes to one decimal place, from preparation for anesthesia until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.

00140 billing questions
When should 00140 be used instead of 00142?
Use 00142 for anesthesia for lens surgery. Use 00140 for an eye procedure that does not belong to a more specifically classified anesthesia service.
Does 00140 cover eyelid reconstruction?
Anesthesia for reconstructive eyelid procedures is classified under 00103. The operative report should make clear whether the service is eyelid reconstruction or another eye procedure.
What documentation supports reporting 00140?
The operative report should identify the eye procedure and treated structures. The anesthesia record should document the anesthesia service and its start and end times.
How does Medicare calculate payment for 00140?
Medicare calculates payment as (5 base units plus time units) multiplied by the anesthesia conversion factor for the payment locality. Time is converted from minutes into 15-minute units, computed to one decimal place.
Is the surgeon's eye procedure included in 00140?
No. The anesthesia practitioner reports the anesthesia service, and the surgeon reports the operative procedure separately.
