Name of the Procedure:

Injection, cosyntropin, not otherwise specified, 0.25 mg (HCPCS Code J0833)

Summary

Cosyntropin injection is a diagnostic procedure used to assess the function of the adrenal glands. It involves administering a synthetic form of adrenocorticotropic hormone (ACTH) to stimulate the adrenal glands and monitor how they respond.

Purpose

Cosyntropin injection helps diagnose conditions related to adrenal insufficiency, such as Addison's disease or secondary adrenal insufficiency. The goal is to determine if the adrenal glands are producing appropriate levels of cortisol in response to ACTH stimulation.

Indications

• Symptoms of adrenal insufficiency (e.g., fatigue, muscle weakness, weight loss, low blood pressure)
• Monitoring adrenal function in patients with known adrenal disorders
• Differentiating between primary and secondary adrenal insufficiency

Preparation

• Fasting may be required for a certain period before the test.
• Patients should inform their healthcare provider about any medications they are taking, as some drugs may need to be temporarily discontinued.

Procedure Description

1. The patient's baseline blood cortisol level is measured.
2. 0.25 mg of cosyntropin is injected intramuscularly or intravenously.
3. Blood samples are drawn at specific intervals (e.g., 30 and 60 minutes post-injection) to measure cortisol levels.
4. The results are compared to baseline levels to assess adrenal function.

Tools & Equipment:

• Cosyntropin ampoules/vials
• Syringes and needles
• Blood collection tubes

Anesthesia or Sedation:

• Not required for this procedure.

Duration

The procedure typically takes about 60 to 90 minutes, including waiting times for blood sample collection.

Setting

Cosyntropin injections can be administered in various healthcare settings, including:

• Hospitals
• Outpatient clinics
• Specialist diagnostic centers

Personnel

Healthcare professionals involved may include:

• Physicians (e.g., endocrinologists)
• Nurses or medical assistants
• Laboratory technicians

Risks and Complications

• Common: Mild discomfort at the injection site, temporary pain during blood draws.
• Rare: Allergic reactions to cosyntropin.

Benefits

• Accurate diagnosis of adrenal gland function.
• Provides crucial information for the management of adrenal insufficiency.
• Results are usually available within a few hours to a couple of days.

Recovery

• Minimal recovery time, most patients can resume normal activities immediately.
• Follow-up instructions may include monitoring for any adverse reactions and scheduling a visit to discuss test results.

Alternatives

• ACTH stimulation tests using different ACTH formulations.
• Insulin-induced hypoglycemia test.
• Pros: Cosyntropin is generally considered safe, quick, and reliable.
• Cons: Other tests might be required if results are inconclusive.

Patient Experience

• Patients may feel a sting or pinch during the injection and blood draws.
• Any discomfort is typically mild and short-lived.
• Healthcare providers may offer ice packs or mild analgesics to ease discomfort, if necessary.
