What 01850 covers

01850 represents anesthesia for a vein procedure involving the forearm, wrist, or hand when the procedure is not represented by a more specific anesthesia category. An anesthesia practitioner reports the anesthetic service; the surgeon reports the underlying operation. The operative record should identify the treated vein, its site, and the procedure, while the anesthesia record supports the anesthesia service and its time.

Choose 01850 for a venous procedure in these regions that is not phleborrhaphy; 01852 identifies anesthesia for phleborrhaphy. Use 01840 for arterial procedures and 01844 for vascular shunt or shunt-revision procedures. 01850 has 3 base units, and Medicare payment is (base units + time units) × the locality’s anesthesia conversion factor. Anesthesia time is recorded in minutes and converted to 15-minute units to one decimal place, from when the practitioner begins preparing the patient until personal attendance ends and the patient can safely enter postoperative care; the conversion factor varies by locality.

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.

How the 01850 rate is calculated

Each of 01850’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

01850 billing questions

When should 01850 be selected instead of 01852?

Use 01850 for a forearm, wrist, or hand vein procedure that is not phleborrhaphy. Use 01852 for anesthesia for phleborrhaphy.

How does 01850 differ from 01840?

01850 is for procedures on veins in the forearm, wrist, or hand. 01840 is for procedures on arteries in those regions.

What should the operative and anesthesia records show?

The operative report should identify the vein, the forearm, wrist, or hand site, and the procedure performed. The anesthesia record should support the reported time, including its start and end points.

How are Medicare anesthesia units calculated for 01850?

The code has 3 base units. Medicare adds time units, calculated from anesthesia minutes in 15-minute units to one decimal place, then multiplies the total by the locality’s anesthesia conversion factor.

Is the vein operation reported with this anesthesia code?

The surgeon reports the vein procedure, while 01850 represents the anesthesia service for that procedure.

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.
