CPT code 01486: Ankle replacement anesthesia, open total joint replacement2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 01486 in California.

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

What 01486 covers

01486 represents anesthesia for open replacement of the ankle joint with a prosthesis. An anesthesiologist or CRNA reports the anesthesia service while supporting ankle arthroplasty, commonly in a hospital or ambulatory surgical setting. The operation replaces the ankle joint rather than treating a fracture, performing an isolated tendon repair, or using arthroscopy.

Choose this code when the operative report documents open total ankle replacement; use a different anesthesia code for ankle or foot arthroscopy, other open lower-leg, ankle, or foot work, or total knee replacement. The operative record should identify the ankle joint replacement and open approach, and the anesthesia record should support the practitioner’s service. This code has 7 base units; Medicare payment is (base units + time units) × the locality-specific anesthesia conversion factor. Anesthesia time begins when the practitioner starts preparing the patient and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care; reported minutes are converted to 15-minute time units to one decimal place.
