ICD-10 Code for ConjunctivitisNOS
Also indexed as (staphylococcal) (streptococcal)
The ICD-10-CM code for conjunctivitisnos is H10.9 — Unspecified conjunctivitis. This is the code the Alphabetic Index gives for conjunctivitisnos with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
H10.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
