About ICD-9-CM 02.41

02.41 is an ICD-9-CM procedure code for irrigation and exploration of ventricular shunt. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-PCS took over.

The CMS General Equivalence Mappings translate it to 3 ICD-10-PCS codes, such as 3C1ZX8Z (Irrigation of Indwelling Device using Irrigating Substance, External Approach), 3E1Q38X (Irrigation of Cranial Cavity and Brain using Irrigating Substance, Percutaneous Approach, Diagnostic) and 3E1Q38Z (Irrigation of Cranial Cavity and Brain using Irrigating Substance, Percutaneous Approach). All of these are approximate matches, so review the record to pick the right one.
