The term "irrigation" in ICD-10-PCS relates primarily to which body system?

The term "irrigation" in ICD-10-PCS primarily relates to the respiratory system. In this context, irrigation refers to the process of introducing fluid into a body cavity or organ for therapeutic purposes, such as cleaning or flushing out secretions and debris in the respiratory tract. This procedural aspect is particularly relevant in cases involving treatments like bronchial irrigation.

While irrigation could potentially apply to other systems for various therapeutic procedures, the primary association in ICD-10-PCS is indeed with the respiratory system due to its specific use in respiratory treatments and interventions. Therefore, it's essential to recognize the context and importance of irrigation within the set coding standards, as it delineates the procedures conducted to maintain or restore the proper functioning of the respiratory tract.
