What 00836 covers
This code covers anesthesia for hernia repair in an infant born before 37 weeks of gestation who is younger than 50 weeks postconceptual age at surgery. An anesthesia practitioner provides and reports the anesthesia service separately from the surgeon’s hernia repair, typically for an operation in a hospital setting.
Choose 00836 when both age criteria are met. Code 00834 is for hernia repair anesthesia in infants younger than 1 year; 00830 describes general lower-abdominal hernia repair, and 00832 is associated with ventral or incisional repairs. The anesthesia and operative records should identify the repair and document gestational age at birth and age at surgery; the anesthesia record should support the service and its start and end times. Medicare assigns 6 base units, and payment is (base units + time units) multiplied by the locality’s anesthesia conversion factor. Time runs from when the practitioner begins preparing the patient for anesthesia until personal attendance ends and the patient can safely be placed under postoperative care; minutes convert to 15-minute units to one decimal place.
