Extrapyramidal and movement disorders in diseases classified elsewhere (G26) ICD-10-CM
The G26 code range covers extrapyramidal and movement disorders in diseases classified elsewhere with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the 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.

About the G26 Code Range
The ICD-10 code G26 is used for identifying extrapyramidal and movement disorders that occur as part of other diseases classified elsewhere in the ICD-10 system. This code helps specify movement-related symptoms that are not primary diagnoses but are linked to underlying conditions.
Extrapyramidal and movement disorders refer to involuntary movements, muscle rigidity, or tremors often seen in neurological illnesses. When these symptoms arise as complications or associated features of other diseases, G26 captures this relationship by classifying the movement issues secondary to the primary condition. Unlike codes for primary movement disorders such as Parkinson’s disease, the ICD-10 code for extrapyramidal and movement disorders in diseases classified elsewhere serves to detail the nervous system effects occurring in context with other illnesses. This distinction is important for accurate medical records, billing, and treatment planning where movement disturbances are a known consequence but not the main diagnosis.
