Name of the Procedure:

HCPCS Procedure Code G9928: Warfarin or another FDA-approved anticoagulant not prescribed, reason not given.

Summary

This coding is used in medical billing to indicate that a clinician has not prescribed Warfarin or another FDA-approved anticoagulant, and no reason for this omission is provided.

Purpose

The purpose of this code is to document instances where anticoagulation therapy, typically used to prevent blood clots, is not prescribed without an accompanying rationale. It helps in quality reporting and ensuring standards of care are met.

Indications

• Patients with atrial fibrillation, deep vein thrombosis (DVT), pulmonary embolism (PE), or other conditions that typically warrant anticoagulation but for whom such therapy was not initiated.
• Cases where anticoagulation therapy might generally be expected but was omitted with no documented reason.

Preparation

• No specific preparation is necessary for the documentation of this code.
• Standard diagnostic tests for anticoagulation therapy (e.g., INR levels) are typically performed beforehand but are not specific to this coding entry.

Procedure Description

This is not a physical procedure but an administrative coding entry:

1. Healthcare professional reviews the patient's condition.
2. Anticoagulation therapy is evaluated for appropriateness.
3. Decision not to prescribe is documented.
4. Code G9928 is entered into the patient's medical record and billing system when no reason is given for the omission of therapy.

Duration

The documentation process typically takes a few minutes during the patient's consultation or medical record review.

Setting

Often performed in various healthcare settings, including:

• Hospitals
• Outpatient clinics
• Physician offices

Personnel

• Physicians
• Nurses
• Medical coding specialists
• Billing professionals

Risks and Complications

• Potential increased risk of thromboembolic events (blood clots) due to lack of anticoagulation.
• Possible liability for healthcare provider if omission of anticoagulation without a documented reason leads to patient harm.

Benefits

• Ensures accountability and thorough documentation in cases where anticoagulation therapy is withheld.
• Helps in quality improvement and patient safety oversight.

Recovery

No recovery is associated with the documentation of this code itself:

• Patients may require regular follow-up to reassess the need for anticoagulation therapy.

Alternatives

While the code itself has no alternatives, alternative treatments or therapies might include:

• Prescription of other anticoagulants like Apixaban, Rivaroxaban, or Dabigatran, with proper documentation.
• Non-pharmacological management strategies with appropriate rationale documented.

Patient Experience

• No direct experience since this involves administrative coding rather than a physical procedure.
• Importance of discussing with patients the reasons for not prescribing anticoagulation therapy to ensure informed decision-making.
