CPT® Code 88347

Deleted

1. Indications

The immunofluorescent study represented by CPT® Code 88347 is indicated for various clinical scenarios where there is a suspicion of disease affecting red blood cells. The following conditions may warrant the use of this procedure:

• Autoimmune Hemolytic Anemia This condition occurs when the immune system mistakenly attacks and destroys red blood cells, leading to anemia.
• Hemolytic Disease of the Newborn This condition arises when there is an incompatibility between the blood types of the mother and the fetus, potentially leading to the destruction of the fetus's red blood cells.
• Transfusion Reactions These reactions can occur when a patient receives incompatible blood, prompting an immune response against the transfused red blood cells.
• Other Blood Disorders Various other hematological conditions may also necessitate the use of immunofluorescent studies to identify specific antibodies or antigens.

2. Procedure

The procedure for conducting an immunofluorescent study using CPT® Code 88347 involves several key steps that ensure accurate testing and diagnosis. Each step is crucial for the successful identification of antibodies in the blood serum.

• Step 1: Sample Collection The first step involves the collection of a blood sample from the patient. This sample is typically processed to obtain serum, which is the liquid portion of the blood that remains after clotting. The serum is essential for the subsequent testing of antibodies.
• Step 2: Preparation of Antibodies In this step, specific antibodies that are suspected to react with the target antigens in the red blood cells are selected. These antibodies are then labeled with a fluorescent dye, which will allow for visualization under a fluorescence microscope.
• Step 3: Incubation The fluorescently labeled antibodies are added to the serum sample and incubated for a specified period. This incubation allows the antibodies to bind to any corresponding antigens present in the serum, forming antigen-antibody complexes.
• Step 4: Washing After incubation, the sample is washed to remove any unbound antibodies. This step is critical to reduce background fluorescence and enhance the specificity of the test results.
• Step 5: Visualization The final step involves examining the sample under a fluorescence microscope. The presence of fluorescence indicates a positive reaction, confirming the presence of specific antibodies against the target antigens in the serum.

3. Post-Procedure

Post-procedure care following an immunofluorescent study coded with CPT® 88347 typically involves monitoring the patient for any immediate reactions, especially if the test was part of a broader diagnostic workup for blood disorders. The results of the immunofluorescent study will be analyzed and interpreted by a qualified healthcare professional, who will then discuss the findings with the patient. Depending on the results, further testing or treatment may be necessary. It is also important for healthcare providers to document the findings accurately and ensure that any follow-up actions are clearly communicated to the patient and relevant medical staff.
