What 00320 covers

This code covers anesthesia for neck operations in patients age one or older when a more specific anesthesia code does not describe the procedure. Typical cases include thyroid or parathyroid operations, cervical lymph node procedures, and surgery for a neck mass. An anesthesiologist or CRNA reports the anesthesia service; the surgeon reports the operative procedure separately.

Choose the code from the actual operative site and procedure: thyroid needle biopsy has a specific code, as do major neck-vessel procedures and integumentary procedures involving the head, neck, or posterior trunk. The operative report should identify the procedure and site; the patient record should establish age, and the anesthesia record should document anesthesia time. This code has 6 base units. Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor; time is converted from minutes to 15-minute units to one decimal, from anesthesia preparation until personal attendance ends 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.

00300Head and neck anesthesiaSkin, muscle, and nerve procedures
Choose 00300 for procedures involving the integument of the head, neck, or posterior trunk; choose 00320 for qualifying neck operations outside that description.
00326Airway anesthesiaLarynx or trachea, under 1 year
00326 is for larynx or trachea procedures in patients younger than one year. For patients age one or older, select the anesthesia code matching the specific procedure.
00350Neck vascular anesthesiaMajor-vessel procedures
00350 is for major-vessel procedures in the neck. Use 00320 for other qualifying neck operations when no more specific code applies.

00320 billing questions

When should 00320 be used instead of 00322?

Use 00322 for anesthesia for a needle biopsy of the thyroid. Use 00320 for other qualifying neck procedures when no more specific anesthesia code describes the operation.

How does 00320 differ from 00300?

00320 is for neck operations. 00300 applies to procedures involving the integument of the head, neck, or posterior trunk, so the operative site and tissue treated determine the choice.

Which code applies to larynx or trachea surgery in an infant?

00326 is the specific anesthesia code for larynx or trachea procedures in patients younger than one year. For patients age one or older, select the code that fits the procedure performed.

What should the records show?

The operative report should name the neck procedure and site, the patient record should establish age, and the anesthesia record should document the start and end of anesthesia time.

How are time units calculated for 00320?

Medicare converts anesthesia minutes to 15-minute time units, calculated to one decimal place. The interval begins with anesthesia preparation and ends when personal attendance ends and the patient can safely be placed under postoperative care.

Is the surgeon’s procedure included in 00320?

No. 00320 reports the anesthesia service; the surgeon reports the operative procedure separately.

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.
