2023 ICD-10-CM Diagnosis Code G09
Sequelae of inflammatory diseases of central nervous system
2016 2017 2018 2019 2020 2021 2022 2023 Billable/Specific Code
- G09 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
- The 2023 edition of ICD-10-CM G09 became effective on October 1, 2022.
- This is the American ICD-10-CM version of G09 - other international versions of ICD-10 G09 may differ.

ICD-10-CM Diagnosis Code G09
Sequelae of inflammatory diseases of central nervous system
2016 2017 2018 2019 2020 2021 2022 2023 Billable/Specific Code
Code First- condition resulting from (sequela) of inflammatory diseases of central nervous system
Note- Category G09 is to be used to indicate conditions whose primary classification is to G00-G08 as the cause of sequelae, themselves classifiable elsewhere. The 'sequelae' include conditions specified as residuals.

Code FirstCode First Help
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation. In most cases the manifestation codes will have in the code title, "in diseases classified elsewhere." Codes with this title are a component of the etiology/manifestation convention. The code title indicates that it is a manifestation code. "In diseases classified elsewhere" codes are never permitted to be used as first listed or principle diagnosis codes. They must be used in conjunction with an underlying condition code and they must be listed following the underlying condition.
