H10 Conjunctivitis
ICD-10-CM category H10 sits in Chapter 7 (Diseases of the eye and adnexa, H00-H59). It contains 72 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.
