326 is a legacy ICD-9-CM diagnosis code for late effects of intracranial abscess or pyogenic infection. It was valid on U.S. claims through September 30, 2015 and cannot be reported for services on or after October 1, 2015, when ICD-10-CM replaced the ICD-9 code set. Under the CMS General Equivalence Mappings, its ICD-10-CM replacement is G09 (Sequelae of inflammatory diseases of central nervous system), flagged as an approximate match.

Information for Patients

Abscess

An abscess is a pocket of pus. You can get an abscess almost anywhere in your body. When an area of your body becomes infected, your body's immune system tries to fight the infection. White blood cells go to the infected area, collect within the damaged tissue, and cause inflammation. During this process, pus forms.

Questions About 326

Is 326 (late effects of intracranial abscess or pyogenic infection) still a valid code?

No. This code belonged to ICD-9-CM, which the United States retired after September 30, 2015. Claims with dates of service on or after October 1, 2015 must use ICD-10-CM codes, such as its replacement G09.

What is the ICD-10 replacement for 326?

The General Equivalence Mappings crosswalk this code to ICD-10-CM G09 (Sequelae of inflammatory diseases of central nervous system). The match is flagged as approximate, so confirm it against the clinical documentation before use.

What did 326 mean?

In the final ICD-9-CM release, this code described late effects of intracranial abscess or pyogenic infection. It sat in block 326 Late effects of intracranial abscess or pyogenic infection under Diseases of the nervous system (320–359).
