What 00145 covers
This code covers anesthesia for operations on the back of the eye, where surgeons treat the vitreous gel or retina. Common cases include vitrectomy, retinal detachment repair, and surgery to remove membranes affecting the retina. An anesthesiologist or CRNA reports the anesthesia service in a hospital or ambulatory surgical setting; the ophthalmic surgeon reports the operation separately.
Choose this code for vitreoretinal surgery rather than the general eye-procedure code or codes specific to lens, corneal, or iris procedures. The anesthesia record should support the practitioner’s work and time; the operative report should identify the retinal or vitreous procedure performed. The code has 6 base units, and Medicare payment is (base units plus time units) multiplied by the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units 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.

00145 billing questions
When should this code be chosen over the general eye-procedure anesthesia code?
Use this code when the operation treats the vitreous or retina, such as vitrectomy or retinal detachment repair. The general eye-procedure code is for eye operations not represented by a more specific anesthesia code.
Does this code cover the surgeon’s retinal operation?
No. It represents the anesthesia service; the ophthalmic surgeon reports the operative procedure separately.
How many base and time units are reported?
This code has 6 base units. Report anesthesia time in minutes; CMS converts it to 15-minute units calculated to one decimal place.
What records support reporting this code?
The anesthesia record should document the anesthesia service and its start and end times. The operative report should show that the procedure involved the vitreous or retina.
How is medically directed anesthesia treated by Medicare?
When an anesthesiologist medically directs a CRNA, Medicare pays each 50% of the allowance for the personally performed service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
