CPT® Code 0565T

1. Indications

The procedure associated with CPT® Code 0565T is indicated for the treatment of osteoarthritis of the knees. This condition is characterized by the breakdown of joint cartilage, leading to various symptoms and complications. The following are specific indications for this procedure:

• Osteoarthritis of the knees - A chronic condition where the cartilage in the knee joint deteriorates, resulting in pain, swelling, and stiffness.

2. Procedure

The procedure for CPT® Code 0565T involves several critical steps to ensure the effective treatment of knee osteoarthritis through the use of autologous adipose-derived cellular implants. The following steps outline the procedure:

• Step 1: Tissue Harvesting - The first step involves harvesting adipose tissue from the patient. This is typically performed using subcutaneous liposuction techniques, targeting areas with excess fat such as the abdomen, flank, or thigh. The procedure may utilize a syringe or cannula to aspirate the fat tissue, ensuring a sufficient quantity is collected for processing.
• Step 2: Processing of Adipose Tissue - Once the adipose tissue is harvested, it undergoes processing to derive mesenchymal stem cells. This processing may include methods such as centrifugation, sedimentation, or washing and filtration. These techniques are employed to increase the concentration of stem cells while removing contaminants, including cellular debris, oils, and blood cells, thereby preparing a viable cellular implant.
• Step 3: Implantation of the Cellular Graft - After processing, the next step is the implantation of the adipose-derived graft into the knee joint. This is typically performed through one or multiple small incisions made over the knee. The implantation is conducted using a needle or small-gauge cannula, often under ultrasound guidance to ensure accurate placement. Prior to injecting the adipose-derived graft, synovial fluid is withdrawn from the joint to create space for the implant.

3. Post-Procedure

Post-procedure care following the implantation of the autologous cellular implant is essential for optimal recovery and outcomes. Patients may experience some swelling and discomfort in the knee area, which is typically managed with standard post-operative care protocols. It is important for patients to follow their physician's instructions regarding activity restrictions and rehabilitation exercises to promote healing. Regular follow-up appointments may be scheduled to monitor the patient's progress and assess the effectiveness of the treatment in alleviating symptoms associated with knee osteoarthritis.
