Codes by condition The ICD-10-CM code for cataract is H26.9 — Unspecified cataract. This is the code the Alphabetic Index gives for cataract with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
Billable Unspecified
H26.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which cataract code should you use? The Alphabetic Index lists 41 codes under Cataract . 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.
