ICD-10-CM category G71 sits in Chapter 6 (Diseases of the nervous system, G00-G99). It contains 28 billable codes for FY2027, effective October 1, 2026 to September 30, 2027. Always code to the most specific code available: a code with more characters that describes the diagnosis more precisely takes priority over a shorter one.
