Non-ABO incompat w hemolytic transfs react, unsp, sequela

This code signifies a long-term or residual effect stemming from a hemolytic transfusion reaction that was not caused by ABO incompatibility. It indicates that the specific type of non-ABO incompatibility is unknown or not documented. The patient is no longer experiencing the acute phase of the reaction but is dealing with its lasting consequences.

Use this code when documenting a patient's current condition that is a direct result of a past non-ABO hemolytic transfusion reaction, and the specific incompatibility was not identified. This applies to follow-up encounters where the sequelae are being managed. Do not use for the acute phase of the reaction.

• Requires a seventh character "S" to indicate sequela.
• Always code the specific sequela (e.g., renal failure, anemia) first, followed by this code to identify the cause.
• Ensure documentation clearly links the current condition to a previous non-ABO hemolytic transfusion reaction.
