Name of the Procedure:

Hyaluronan or derivative, Genvisc 850, for intra-articular injection, 1 mg (J7320)

Summary

This procedure involves injecting a gel-like substance called Genvisc 850, derived from hyaluronan, into the joint (intra-articular) to provide relief from joint pain and improve mobility. Hyaluronan is a natural component of the joint fluid that acts as a lubricant and shock absorber.

Purpose

To alleviate pain and improve joint function in patients with osteoarthritis or other degenerative joint conditions. The goal is to reduce discomfort and enhance movement in the affected joint.

Indications

• Chronic joint pain due to osteoarthritis, especially in the knee
• Patients who have not responded adequately to other treatments such as pain medications or physical therapy
• Seeking to delay more invasive procedures like joint replacement surgery

Preparation

• No specific fasting required.
• Inform your healthcare provider about any medications you are taking, especially blood thinners.
• A physical examination and possibly imaging tests (like X-rays) to assess the joint condition.

Procedure Description

1. The affected joint is cleaned and sterilized.
2. Local anesthesia may be applied to numb the area.
3. Using a fine needle, Genvisc 850 is injected directly into the joint space.
4. The needle is removed, and a small bandage is applied.

Duration

The entire procedure typically takes about 15-30 minutes.
