CPT® Code 86910

1. Indications

The procedure coded as CPT® 86910 is indicated for use in situations where paternity needs to be established. This may include, but is not limited to, the following circumstances:

• Paternity Disputes Situations where the biological relationship between a father and child is questioned, often in legal contexts such as custody battles or child support cases.
• Legal Requirements Cases where legal documentation of paternity is required for inheritance, social security benefits, or other legal rights.
• Personal Reasons Individuals seeking to confirm biological relationships for personal knowledge or family health history.

2. Procedure

The procedure for blood typing for paternity testing involves several key steps, which are outlined as follows:

• Step 1: Sample Collection Blood samples are collected from both the male and the child. This is typically done through venipuncture, where a needle is inserted into a vein to draw blood. Proper techniques and sterile equipment are essential to ensure the safety and integrity of the samples.
• Step 2: Laboratory Analysis The collected blood samples are sent to a laboratory where they undergo analysis. The laboratory technicians will identify the ABO blood group, Rh factor, and MN antigen types present in both samples. This analysis is crucial for determining compatibility and potential biological relationships.
• Step 3: Comparison of Results Once the blood types are identified, the results are compared. The laboratory will assess the blood types of the male and the child to calculate the statistical probability of paternity. This probability indicates how likely it is that the male is the biological father based on the blood type compatibility.
• Step 4: Reporting The final step involves compiling the results into a report that details the findings of the blood typing. This report will include the blood types of both individuals and the calculated probability of paternity, which can be used in legal or personal contexts as needed.

3. Post-Procedure

After the blood typing procedure is completed, there are typically no specific post-procedure care requirements for the individuals involved, as the procedure is minimally invasive. However, it is important for the individuals to be informed about the potential outcomes of the test. If the results are conclusive, they can be used for legal or personal purposes as intended. If the results are inconclusive, further testing may be necessary, which would be coded under CPT® Code 86911. Individuals should also be advised to follow up with their healthcare provider to discuss the results and any implications they may have.
