ICD-10 Code for Hernia
Also indexed as (acquired) (recurrent)
The ICD-10-CM code for hernia is K46.9 — Unspecified abdominal hernia without obstruction or gangrene. This is the code the Alphabetic Index gives for hernia with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
K46.9 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which hernia code should you use?
The Alphabetic Index lists 62 codes under Hernia, hernial. 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.
