T46 Agents primarily affecting the cardiovascular system

ICD-10-CM category T46 sits in Chapter 20 (External causes of morbidity, V00-Y99). It contains 198 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.
