AIClinical Context

Clinical Description

This code represents the administration of 500 mg of metronidazole via injection. Metronidazole is an antibiotic and antiprotozoal medication commonly used to treat a variety of bacterial and parasitic infections. It is often administered intravenously for more severe infections or when oral administration is not feasible.

When to Use

This code is used when metronidazole 500 mg is administered parenterally, typically in an outpatient setting. Common scenarios include treatment for anaerobic bacterial infections, trichomoniasis, or amebiasis. Documentation should clearly specify the drug, dosage, route of administration, and medical necessity for the injection.

Coding Tips

Ensure the documentation specifies the 500 mg dosage; other dosages may require a different code or be billed per unit.

This code is for the drug itself, not the administration service. A separate CPT code for the injection administration (e.g., 96372) should be billed concurrently.

Verify the payer's specific guidelines for billing injectables, as some may prefer NDC codes or have quantity limitations.
