Answer: Medicares allowance is based on 4 units. You must remember that most cataract surgeries are also monitored anesthesia care (MAC) cases. The American Society of Anesthesiologists (ASA) Relative Value Guide does allow 6 units for 00142, but Medicare differs from ASA in many cases. Medicares allowance for 00142 is 4 units, although most commercial carriers will allow 6 units for this procedure.
