Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 01400 covers

This service covers anesthesia for open or arthroscopic surgery involving the knee joint, including arthroscopic meniscal or ligament procedures and other open joint operations. An anesthesiologist or CRNA provides and reports the anesthesia, commonly in a hospital or ambulatory surgery center; the surgeon reports the operative procedure separately.

Select 01400 for knee-joint operations other than total knee arthroplasty or disarticulation at the knee. The anesthesia record should identify the operation and approach and document anesthesia start and end times; the operative report should support the procedure and knee site. The code carries 4 base units, and Medicare payment is (base units + time units) multiplied by the locality’s anesthesia conversion factor. Anesthesia 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 time units, calculated to one decimal place.
