What 01402 covers

This service accompanies total knee replacement, in which the knee joint is surgically replaced with prosthetic components. An anesthesiologist or CRNA typically reports the anesthesia for a hospital or ambulatory surgical facility case; the surgeon reports the arthroplasty separately.

Choose 01402 when the operative procedure is total knee arthroplasty, rather than 01400 for other open or arthroscopic knee-joint procedures or 01404 for knee disarticulation. The operative record should identify the arthroplasty, and the anesthesia record should support the practitioner’s service and its start and end times. This code has 7 base units; Medicare payment is (base units plus time units) multiplied by the locality’s anesthesia conversion factor. Time is recorded in minutes from anesthesia preparation until the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care, then converted to 15-minute units to one decimal place; the conversion factor varies by locality.

01402 billing questions

When should 01402 be chosen instead of 01400?

Use 01402 when the operation is a total knee arthroplasty. Code 01400 is for other open or arthroscopic procedures on the knee joint.

Does 01402 cover knee disarticulation?

No. Knee disarticulation is reported with anesthesia code 01404; 01402 is for total knee arthroplasty.

What documentation supports reporting 01402?

The operative record should identify the total knee arthroplasty. The anesthesia record should support the anesthesia practitioner’s service and document the start and end times.

How are the units calculated?

The code has 7 base units. Anesthesia time is reported in minutes and converted to 15-minute units to one decimal place; Medicare payment uses (base units plus time units) multiplied by the locality’s anesthesia conversion factor.

Is the surgeon’s arthroplasty reported separately?

Yes. The surgeon reports the knee arthroplasty, while the anesthesia professional reports the anesthesia service.

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.
