What 00148 covers
This service covers anesthesia for ophthalmoscopic examination of the eye, including examination of the fundus when the patient cannot tolerate the examination while awake. It is commonly used for young children or patients unable to cooperate with a necessary eye examination. An anesthesia practitioner provides and reports the anesthesia service in an office or facility setting; the ophthalmologist performs and documents the examination.
Choose this code when ophthalmoscopy is the anesthetized procedure, rather than anesthesia for a separately defined eye operation such as lens, corneal, retinal, or iris surgery. The operative record should identify the examination performed, and the anesthesia record should support the service and its time. This code has 4 base units; Medicare payment is (base units plus time units) multiplied by the anesthesia conversion factor, which varies by locality. Anesthesia time is counted in minutes from when the practitioner begins preparing the patient until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; CMS converts minutes to 15-minute units to one decimal place.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

00148 billing questions
When should 00148 be chosen instead of 00140?
Use 00148 when the anesthetized service is ophthalmoscopy. Code 00140 describes anesthesia for other eye procedures not otherwise specified.
Does an incidental look inside the eye during surgery make this the right code?
No. An incidental ophthalmoscopic view during another eye operation does not make ophthalmoscopy the anesthetized procedure; use the anesthesia category for the operation being performed.
Who reports 00148?
The anesthesia practitioner reports the anesthesia service. The ophthalmologist reports the examination or other eye service performed.
What records support the anesthesia claim?
The operative record should identify the ophthalmoscopic examination, and the anesthesia record should document the anesthesia service and its start and end times.
How are time units calculated for 00148?
Report anesthesia time in minutes; CMS converts it to 15-minute units, calculated to one decimal place. Medicare uses the 4 base units plus time units, multiplied by the locality’s anesthesia conversion factor.
How is medically directed anesthesia paid?
When an anesthesiologist medically directs a CRNA, Medicare pays each 50% of the allowance for the personally performed service.
