CPT code 01490: Lower-leg cast anesthesia, application, removal, or repair2026 Medicare rate & RVUs in Michigan

CMS doesn’t publish an office rate for 01490 in Michigan.

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

What 01490 covers

This anesthesia service covers lower-leg cast application, removal, or repair when anesthesia is provided for the cast procedure. An anesthesiologist or CRNA furnishes and reports the anesthesia; the cast procedure is a separate service. Medicare utilization for 01490 is recorded in facility claims. The operative documentation should identify the cast action and treated site, while the anesthesia record supports the practitioner’s time and attendance.

Choose 01490 for lower-leg cast work, not knee-joint cast care under 01420 or anesthesia for a separate closed or open lower-extremity operation, represented by 01462 and 01480. The code has 3 base units. Medicare calculates payment as base units plus time units multiplied by the locality’s anesthesia conversion factor. Anesthesia time is counted in minutes from preparation of the patient through the end of personal attendance, when the patient can safely be placed under postoperative care, then converted to 15-minute units to one decimal place; conversion factors vary by locality.
