Name of the Procedure:

Angiotensin Converting Enzyme (ACE) Inhibitor or Angiotensin Receptor Blocker (ARB) Therapy Exclusion due to Medical Reasons (HCPCS code: G8474)

Summary

This procedure involves a clinician documenting the specific medical reasons why a patient should not be prescribed an ACE inhibitor or ARB therapy. This may be due to allergies, intolerances, pregnancy, renal failure due to ACE inhibitors, or specific diseases of the aorta or other contraindications.

Purpose

The medical conditions or problems it addresses:

This documentation addresses situations where ACE inhibitors or ARB therapies are contraindicated due to patient-specific factors.

The goals or expected outcomes of the procedure:

The goal is to ensure patient safety by avoiding medications that may cause adverse effects or harm in certain populations. This enforces appropriate medication management based on individual patient health conditions.

Indications

Specific symptoms or conditions that warrant the procedure:

• Known allergy to ACE inhibitors or ARBs
• Intolerance to these medications causing significant side effects
• Pregnancy, where these drugs can be harmful to the fetus
• Renal failure or worsening kidney function attributed to ACE inhibitors
• Diseases of the aorta or other specific cardiovascular conditions that contraindicate the use of these medications

Patient criteria or factors that make the procedure appropriate:

• Documented medical history that contains any of the conditions above
• Clinical assessment supporting contraindication

Preparation

Pre-procedure instructions for the patient:

There are no specific preparatory steps for the patient, but they need to provide a full medical history to their clinician.

Any diagnostic tests or assessments required beforehand:

Relevant tests could include renal function tests, allergy tests, and a thorough review of the patient’s medication tolerance history.

Detailed step-by-step explanation of what the procedure involves:

1. Medical evaluation by the clinician to identify contraindications.

Risks and Complications

Common and rare risks associated with the procedure:

As this is a documentation process, there are no physical risks associated. However, risks are associated with the underlying conditions or adverse reactions that led to the contraindication.

Possible complications and their management:

Potential for a gap in therapy if alternative treatment is not initiated promptly. Management would involve timely consultation and prescription of suitable alternative therapy.

Benefits

Expected benefits and how soon they might be realized:

Immediate patient safety by avoiding harmful medications. Proper documentation ensures continuity of care and informs all healthcare providers about the contraindications for future treatment decisions.

Recovery
