2025 HCPCS code A4929
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Medical Supplies - Dialysis Equipment and Supplies Medical and Surgical Supplies Feed
Reports a tourniquet used during dialysis; one code per tourniquet.
Modifiers may be applicable depending on the circumstances of service (e.g., KX for medical necessity, etc). Refer to the most recent CMS guidelines and NCCI edits.
Medical necessity is established by the documented need for dialysis treatment, along with the clinical indication that a tourniquet was necessary to facilitate safe and efficient vascular access.
The clinical responsibility lies with the physician or qualified healthcare professional performing the dialysis procedure and applying the tourniquet.This includes appropriate vein selection, tourniquet placement to ensure adequate venous access while minimizing patient discomfort, and monitoring for complications.
In simple words: This code is for a special band used to help doctors find a vein easily during dialysis (a blood cleaning treatment). The band is used on the arm to make it easier to put a needle in the vein.
This HCPCS code, A4929, represents a tourniquet used by a provider during a dialysis procedure.A tourniquet is a device used to temporarily compress a limb, constricting blood flow to facilitate vein access. In dialysis, it helps to visualize and stabilize the vein for arteriovenous fistula cannulation. The provider gently applies the tourniquet to the axilla (armpit) region, controlling bleeding and improving vein access without completely occluding blood flow.One code is reported for each tourniquet used.
Example 1: Scenario 1: A patient undergoing hemodialysis requires vascular access. The nephrologist uses a tourniquet to aid in cannulating the arteriovenous fistula in the patient's arm. One unit of A4929 is reported., Scenario 2: During a peritoneal dialysis session, the nurse uses a tourniquet on the patient's arm for easier vein access during an emergency situation requiring intravenous medications.One unit of A4929 is reported., Scenario 3: A patient requires multiple attempts at vascular access during hemodialysis due to difficult-to-access veins.The nephrologist utilizes a tourniquet at each puncture site, resulting in two units of A4929 being reported.
Documentation should include the medical record indicating the necessity of dialysis, the number of tourniquets used,the location of application, and any complications arising from the use of the tourniquet.
** This code is specific to tourniquets used during dialysis procedures and should not be used for tourniquets in other contexts.Always refer to the most up-to-date HCPCS coding manual.
