What 00350 covers

This service covers anesthesia for surgery on major blood vessels in the neck, commonly carotid operations such as carotid endarterectomy. An anesthesiologist or CRNA may report it for hospital or other surgical-facility care. The anesthesia record should identify the anesthesia practitioner and document the care provided; the operative report should establish the major neck vessel treated and the procedure performed.

Choose this code for major-vessel neck surgery rather than general neck procedures or simple vessel ligation. Carotid endarterectomy, commonly reported with CPT 35301, is a typical pairing. Medicare payment is (10 base units + time units) multiplied by the locality’s anesthesia conversion factor. Anesthesia time is reported in minutes and converted to 15-minute units to one decimal place; it begins when the practitioner starts preparing the patient for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

00350 billing questions

When should this code be chosen instead of 00352?

Use 00350 for major-vessel neck procedures such as carotid endarterectomy. Code 00352 is for simple ligation of a major neck vessel.

How does this differ from 00320?

00350 identifies anesthesia for major-vessel surgery in the neck. Code 00320 covers other neck procedures in patients age one or older.

What should the operative and anesthesia records show?

The operative report should identify the major neck vessel and the procedure performed. The anesthesia record should support the service and document when preparation begins and when personal attendance ends with the patient ready for postoperative care.

How are units calculated for Medicare?

This code has 10 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, and multiplies the total by the locality’s anesthesia conversion factor.

Is carotid endarterectomy a typical procedure for this code?

Yes. Anesthesia for carotid endarterectomy is a common use when the operative report supports surgery on a major neck vessel.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
