What 01931 covers

This service covers anesthesia for therapeutic image-guided intervention directed at the intrahepatic or portal circulation. A typical example is creation of a transjugular intrahepatic portosystemic shunt (TIPS). An anesthesiologist or CRNA may provide the service in an interventional radiology suite or hybrid procedural setting while the interventionalist accesses and treats the portal system.

Choose 01931 for treatment involving the intrahepatic or portal circulation, rather than venous intervention not otherwise specified, arterial intervention, or diagnostic vessel imaging alone. The anesthesia record should identify the therapeutic service and document anesthesia start and end times; the interventional report should establish the treated vascular territory and procedure. This code has 7 base units. Medicare payment is (base units plus time units) multiplied by the locality’s anesthesia conversion factor; time is counted in minutes and converted to 15-minute units to one decimal place, from preparation start until the practitioner is no longer personally attending and the patient can safely enter 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.

01931 billing questions

When should 01931 be chosen instead of 01930?

Use 01931 for therapeutic intervention involving the intrahepatic or portal circulation. Code 01930 covers therapeutic interventional radiology involving veins not otherwise specified.

Is TIPS a typical procedure for 01931?

Yes. Creation of a transjugular intrahepatic portosystemic shunt is a typical example of a therapeutic procedure involving the portal circulation.

Does 01931 include the TIPS procedure itself?

No. The anesthesia practitioner reports the anesthesia service, while the interventionalist reports the procedure under the applicable procedural code.

What records support reporting 01931?

The anesthesia record should show the service and anesthesia time. The interventional report should identify the procedure and confirm that it involves the intrahepatic or portal circulation.

How are units calculated for Medicare?

The code has 7 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.

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.
