About the 3E1 Code Range
The ICD-10-PCS root operation Irrigation (code 3E1) involves the administration of a liquid, such as an irrigating substance, to wash out a body part. Classified under the Administration section, this operation cleanses physiological systems and anatomical regions by flushing them with fluid.
This root operation is used to treat or evaluate numerous body parts, including the skin and mucous membranes, nose, ear, eye, and various internal systems like the respiratory tract, gastrointestinal tract (both upper and lower), biliary and pancreatic tracts, genitourinary tract, and cavities such as the pleural, peritoneal, and pericardial cavities. Approaches for irrigation include percutaneous, via natural or artificial openings, and endoscopic techniques. For example, the code 3E1938Z represents irrigation of the nose using a percutaneous approach, while 3E1F88Z codes irrigation of the respiratory tract via natural or artificial opening endoscopically. Both therapeutic and diagnostic irrigations are identified by specific suffixes in the coding system.
Precise use of these ICD-10-PCS irrigation codes ensures accurate documentation of the irrigation procedure performed on a specific anatomical site using the appropriate approach.
Questions About This Page
