What 01474 covers
This service covers anesthesia for gastrocnemius recession, a procedure that lengthens or releases the gastrocnemius portion of the calf muscle-tendon unit. Foot and ankle surgeons commonly perform it to address restricted ankle dorsiflexion, often in patients having treatment for equinus or related foot and ankle problems. The procedure may be performed in a hospital or ambulatory surgery center, and an anesthesia professional reports the anesthesia service.
Use 01474 when the operation is a gastrocnemius recession, rather than a different lower-leg, ankle, or foot procedure. The operative report should identify the recession, and the anesthesia record should support the anesthesia service and its start and end times. Medicare assigns 5 base units; payment is (base units + time units) × the locality’s anesthesia conversion factor. Anesthesia time is reported in minutes and converted to units per 15 minutes, computed 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.
