CPT code 01464: Ankle/foot arthroscopy, ankle or foot arthroscopy2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 01464 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 01464 covers

Code 01464 is for anesthesia supporting arthroscopic surgery in the ankle or foot, where the surgeon works through small incisions with a scope rather than an open exposure. Typical cases include diagnostic joint inspection and arthroscopic treatment of joint pathology, such as removing loose material, debriding tissue, or treating an intra-articular lesion. An anesthesiologist or CRNA reports the anesthesia service in a hospital or ambulatory surgical setting; the orthopedic or podiatric surgeon reports the operative work separately.

Choose 01464 when the operative record documents arthroscopic work at the ankle or foot joint. Use 01480 for open operations in these regions and 01462 for closed procedures; Achilles tendon repair and nerve or muscle procedures have more specific anesthesia codes. The operative record should identify the site, arthroscopic approach, and procedure; the anesthesia record should document the practitioner’s personal attendance times. This code has 3 base units; Medicare calculates payment as (base units + time units) × the locality’s anesthesia conversion factor. Time is reported in minutes and converted to 15-minute units to one decimal place, from when the anesthesia practitioner begins preparing the patient until no longer in personal attendance and the patient can safely be placed under postoperative care.
