CPT Code 27447 | Total Knee Arthroplasty (TKA)

CPT 27447 describes a total knee arthroplasty and is often referred to as TKA. The procedure involves replacing the medial and lateral compartments and possibly the patella of the knee joint.

What Is CPT Code 27447?

CPT code 27447 refers to a specific procedure called total knee arthroplasty, also known as a knee replacement surgery.

The procedure involves replacing the worn or damaged surfaces of the knee joint with artificial components.

The 27447 CPT code specifies that the surgery is being performed on the knee’s medial and lateral compartments. This refers to the inner and outer parts of the joint.

The description of CPT 27447 also notes that the procedure may involve resurfacing the patella (the kneecap). This standard procedure is performed in conjunction with total knee arthroplasty.

Description

The CPT book describes CPT code 27447 as: “Arthroplasty, knee, condyle, and plateau; medial AND lateral compartments with or without patella resurfacing (total knee arthroplasty).”

Procedure

The provider performs knee replacement surgery by making a midline incision over the knee joint, including the patella.

They then carefully dissect the subcutaneous tissue and remove the front fat pad and remaining menisci.

The provider excises any osteophytes and cuts the tight soft tissues around the joint.

The femoral condyles and a portion of the upper tibia in both the medial and lateral compartments are removed.

The provider then carefully removes a portion of bone from the lower femur and upper tibia to create space for the insertion of the implant components.

The tibial and femoral components are inserted and secured using antibiotic-loaded cement or other materials. Then the worn patella may be resurfaced with a prosthesis and fixed in place.

The provider ensures proper alignment and movement of the patella, checks for any loose cement, and stops any bleeding at the surgical site. They then close the joint with sutures and place a drain to remove excess fluid.

How To Use CPT 27447

When billing for total knee arthroplasty, use CPT code 27447. This code is also commonly referred to as TKA.
