ICD-10 Code for Papillitis
The ICD-10-CM code for papillitis is H46.00 — Optic papillitis, unspecified eye. This is the code the Alphabetic Index gives for papillitis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
H46.00 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which papillitis code should you use?
The Alphabetic Index lists 6 codes under Papillitis. Which one applies depends on the qualifier documented in the record — the type, site, cause, or associated condition. Find the qualifier below, then verify the code in the Tabular List before using it.
