Name of the Procedure:

Injection, Crizanlizumab-tmca, 5 mg (HCPCS Code: J0791)

Summary

This procedure involves the administration of Crizanlizumab-tmca, a medication given via injection. It's a targeted therapy used to treat specific conditions related to blood disorders.

Purpose

Crizanlizumab-tmca is primarily used to manage sickle cell disease. It helps reduce the frequency of painful crises and complications by preventing the clumping of blood cells and improving blood flow.

Indications

• Sickle cell disease with frequent pain crises
• Patients over the age of 16
• Previous inadequate response to other sickle cell treatments

Preparation

• No fasting required
• Doctor consultation to review medical history and current medications
• Blood tests to assess overall health and to confirm criteria for treatment

Procedure Description

1. Patient arrives at the clinical setting.
2. A nurse or healthcare provider prepares the injection area (usually the arm).
3. Crizanlizumab-tmca is administered via intravenous (IV) infusion.
4. The injection process is monitored to ensure there are no adverse reactions.
5. The infusion typically takes around 30 minutes to complete.

Duration

The injection itself takes approximately 30 minutes, but overall appointment time might be around 1 to 2 hours including preparation and monitoring.

Setting

This procedure is usually performed in an outpatient clinic or hospital setting, where appropriate monitoring and emergency care are available.

Personnel

• Registered Nurse (RN) or licensed healthcare professional for administration
• Supervising Physician or Specialist
• Support Staff (e.g., medical assistant)

Risks and Complications

• Common: Injection site reactions (redness, swelling), nausea, headache
• Rare: Severe allergic reactions (anaphylaxis), increased risk of infection
• Management: Immediate medical attention for severe reactions, and post-injection monitoring

Benefits

• Reduction in frequency and severity of vaso-occlusive crises
• Improvement in quality of life
• Beneficial effects typically noticed within the first few weeks of treatment

Recovery

• No significant downtime; patients can usually resume normal activities immediately.
• Follow post-injection instructions provided by healthcare professionals.
• Follow-up appointments for subsequent doses and to monitor response to treatment.

Alternatives

• Hydroxyurea: Another medication for reducing sickle cell crises, which may have more side effects.
• Blood transfusions: Useful in severe cases but come with risks of complications.
• Bone marrow or stem cell transplant: Potentially curative but involves significant risks and is not suitable for all patients.

Patient Experience

• During: Mild discomfort or pain at the injection site.
• After: Keeping the injection site clean and observing for any signs of adverse effects.
• Pain management: Over-the-counter pain relievers if needed, as recommended by the healthcare provider.
