What 01474 covers

This service covers anesthesia for gastrocnemius recession, a procedure that lengthens or releases the gastrocnemius portion of the calf muscle-tendon unit. Foot and ankle surgeons commonly perform it to address restricted ankle dorsiflexion, often in patients having treatment for equinus or related foot and ankle problems. The procedure may be performed in a hospital or ambulatory surgery center, and an anesthesia professional reports the anesthesia service.

Use 01474 when the operation is a gastrocnemius recession, rather than a different lower-leg, ankle, or foot procedure. The operative report should identify the recession, and the anesthesia record should support the anesthesia service and its start and end times. Medicare assigns 5 base units; payment is (base units + time units) × the locality’s anesthesia conversion factor. Anesthesia time is reported in minutes and converted to units per 15 minutes, computed to one decimal place, from preparation for anesthesia until 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.

01474 billing questions

When should 01474 be selected instead of 01470?

Use 01474 for anesthesia for a gastrocnemius recession. Code 01470 describes anesthesia for a lower-leg, ankle, or foot nerve or muscle procedure not otherwise specified.

How does 01474 differ from anesthesia for Achilles tendon repair?

01474 is for gastrocnemius recession; 01472 is for anesthesia associated with Achilles tendon repair. Select the code based on the operation documented.

What should the records show?

The operative report should identify the gastrocnemius recession, and the anesthesia record should support the service and document anesthesia start and end times.

How are time units calculated for 01474?

Anesthesia time is recorded in minutes and converted to units per 15 minutes, computed to one decimal place. The interval begins with preparation for anesthesia and ends when personal attendance ends and the patient can safely be placed under postoperative care.

How does Medicare handle medically directed anesthesia for this procedure?

When an anesthesiologist medically directs a CRNA, Medicare pays each 50% of the allowance for the personally performed service. The anesthesiologist reports QK or QY, and the CRNA reports QX.

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.
