Hyaluronan or Derivative, Gel-One, for Intra-Articular Injection (HCPCS J7326)

Name of the Procedure:

• Common Name(s): Joint Gel Injection, Gel-One Injection
• Medical Terms: Hyaluronan Injection, Sodium Hyaluronate Injection, Viscosupplementation

Summary

The Gel-One injection is a medical procedure where a gel-like fluid called hyaluronan is injected into a joint, typically the knee, to relieve pain and improve mobility. This fluid mimics the natural lubricating substance found in healthy joints.

Purpose

• Medical Conditions: Osteoarthritis of the knee
• Goals/Outcomes: Reduce joint pain, enhance joint lubrication, and improve overall joint function and mobility

Indications

• Symptoms: Persistent knee pain, stiffness, and reduced mobility due to osteoarthritis
• Patient Criteria: Patients who have not responded to other treatments like pain medications, physical therapy, or corticosteroid injections

Preparation

• Pre-Procedure Instructions: Patients are generally advised to avoid anti-inflammatory medications for a few days prior to the injection to reduce the risk of bleeding and bruising.
• Diagnostic Tests: An X-ray or MRI may be done to assess the severity of joint degeneration.

Procedure Description

1. The patient is seated or lying down with the affected knee exposed.
2. The injection site is sterilized to prevent infection.
3. A local anesthetic may be applied to numb the area.
4. Using a fine needle, the healthcare provider injects Gel-One directly into the joint space.
5. The injection site may be massaged gently to distribute the gel evenly within the joint.
6. A small bandage may be applied over the injection site.

• Tools/Equipment: Sterile syringe and needle, Gel-One injectable gel, antiseptic swabs, local anesthetic (optional)
• Anesthesia: Local anesthesia may be used to numb the injection site.

Duration

The injection procedure typically takes about 15 to 30 minutes, including preparation time.

Setting

The procedure is commonly performed in an outpatient clinic or a doctor's office.

Personnel

• Healthcare Provider: The procedure is usually conducted by a physician, often an orthopedic specialist or a rheumatologist.
• Support Staff: A nurse or medical assistant may assist.

Risks and Complications

• Common Risks: Mild pain, swelling, or warmth at the injection site
• Rare Risks: Joint infection, allergic reaction, bleeding, or temporary increase in pain

Benefits

• Expected Benefits: Pain relief and improved joint function
• Timeline: Patients may start noticing improvements within a few days to a few weeks after the injection.

Recovery

• Post-Procedure Care: Patients are advised to rest and avoid strenuous activity for at least 48 hours after the injection.
• Recovery Time: Most patients resume normal activities within a few days. Follow-up appointments may be scheduled to monitor progress.

Alternatives

• Other Treatments: Pain medications, physical therapy, corticosteroid injections, knee braces, or surgery (e.g., arthroscopy, knee replacement)
• Pros and Cons: Gel-One is less invasive and can provide relief without the need for surgery, but it may not work for everyone, and its effects are temporary.

Patient Experience

• During Procedure: Patients might feel slight discomfort or pressure during the injection.
• After Procedure: Temporary soreness at the injection site is possible. Pain relief and improved mobility are expected over time. Pain management strategies, including over-the-counter pain relievers or ice packs, may be recommended to enhance comfort.
