About ICD-9-CM 997.09
997.09 is an ICD-9-CM diagnosis code for other nervous system complications. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 4 ICD-10-CM codes, such as G03.8 (Meningitis due to other specified causes), G97.0 (Cerebrospinal fluid leak from spinal puncture) and G97.81 (Other intraoperative complications of nervous system). All of these are approximate matches, so review the record to pick the right one.
