CPT code 00865: Prostatectomy anesthesia, extraperitoneal lower abdomen2026 Medicare rate & RVUs in California

CMS doesn’t publish an office rate for 00865 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 00865 covers

This service covers anesthesia for prostate removal through an extraperitoneal approach in the lower abdomen. A urologist typically performs the operation, often to treat prostate cancer, while an anesthesiologist or CRNA provides and reports the anesthetic in an operating room.

Choose this code for prostatectomy rather than the broader extraperitoneal lower-abdominal category or codes specific to renal surgery, total cystectomy, adrenalectomy, or renal transplantation. The operative report should identify the prostatectomy and extraperitoneal approach; the anesthesia record should support the service and document its start and end times. This code has 7 base units. Medicare payment is (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, starting when the anesthesia practitioner begins preparing the patient and ending when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
