CPT® Code 86930

1. Indications

The procedure associated with CPT® Code 86930 is indicated for the preservation of red blood cells for future transfusion needs. The following conditions or scenarios may warrant the use of this procedure:

• Blood Storage The need to store blood units for patients requiring transfusions at a later date.
• Emergency Transfusions Situations where immediate access to blood products is necessary, necessitating the availability of frozen blood units.
• Blood Component Therapy Patients undergoing treatments that require specific blood components, which may be prepared and stored in advance.

2. Procedure

The procedure for freezing blood units as described by CPT® Code 86930 involves several critical steps to ensure the viability of red blood cells during storage. The process begins with the collection of blood from a donor, which must be reported separately. Once the blood is obtained, it undergoes preparation where the serum or plasma is separated from the red blood cells. This separation is crucial as it allows for the effective preservation of the red cells. Following this, the red blood cells are treated with a glycerol-based cryoprotectant. This preservative is essential as it penetrates the outer membrane of the red cells, displacing water inside the cells, a process known as glycerolization. This step is vital to prevent ice crystal formation during freezing, which can cause the cells to swell and burst. After the glycerolization process, the blood unit is frozen at temperatures of -122.8 °F or lower, ensuring that the red blood cells remain viable for future transfusions. When the blood is needed, it is thawed by placing the unit in a water bath set to 98.6°F (37°C) for approximately 30 minutes. After thawing, the red blood cells undergo a washing process, known as deglycerolization, where they are rinsed with a series of progressively dilute sodium solutions. This step is necessary to remove the glycerol preservative, any white blood cell fragments, and plasma. Once this process is complete, the thawed unit can be stored at temperatures between 1-6°C for up to 24 hours. If the thawed blood unit is not immediately required for transfusion, it may be refrozen, provided that a rejuvenation chemical is added to the unit prior to refreezing.

3. Post-Procedure

After the freezing procedure associated with CPT® Code 86930, specific post-procedure care and considerations are necessary to ensure the integrity and usability of the blood unit. The thawed blood unit must be stored at controlled temperatures between 1-6°C and can remain viable for transfusion for up to 24 hours. It is crucial to monitor the storage conditions to maintain the quality of the red blood cells. If the thawed unit is not used within this timeframe, it may be refrozen, but only if a rejuvenation chemical is added beforehand to ensure the cells remain viable. Proper documentation of the freezing and thawing processes, as well as the storage conditions, is essential for compliance and to facilitate any future transfusion needs. Additionally, healthcare professionals must be aware of the specific protocols for handling and administering thawed blood products to ensure patient safety and optimal outcomes.
