Frequently Asked Questions
What is the ICD-10 code for other disorders of brain in diseases classified elsewhere?
The ICD-10-CM code for other disorders of brain in diseases classified elsewhere is G94. The full clinical description is "Other disorders of brain in diseases classified elsewhere". G94 is a billable/specific code that can be used on insurance claims and medical billing.
What does ICD-10 code G94 mean?
ICD-10-CM code G94 represents “Other disorders of brain in diseases classified elsewhere”. It is classified under Chapter 6: Diseases of the Nervous System and is a billable/specific code that can be used on a claim.
Is G94 a billable code?
Yes, G94 is a billable/specific ICD-10-CM code and can be used to indicate a diagnosis on a medical claim.
What chapter is G94 in?
G94 is in Chapter 6: Diseases of the Nervous System (codes G00-G99).
What codes cannot be used with G94?
G94 has Excludes1 notes indicating codes that cannot be used together with it, including: encephalopathy in congenital syphilis (A50.49); encephalopathy in influenza (J09.X9, J10.81, J11.81); encephalopathy in syphilis (A52.19); and 1 more.
What SNOMED CT codes does G94 map to?
G94 maps to 22 SNOMED CT concepts: 66944004, 68574006, 1275631007, 1290801000000102, 1259515002, and 17 more. SNOMED CT is a clinical terminology used in electronic health records.
