2019 ICD-10-CM Diagnosis Code G63

Polyneuropathy in diseases classified elsewhere

    2016 2017 2018 2019 Billable/Specific Code Manifestation Code
  • G63 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
  • The 2019 edition of ICD-10-CM G63 became effective on October 1, 2018.
  • This is the American ICD-10-CM version of G63 - other international versions of ICD-10 G63 may differ.
ICD-10-CM Coding Rules
  • G63 describes the manifestation of an underlying disease, not the disease itself.
Code First
Code 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.
