ICD-10 Code for Gastritis
Also indexed as (simple)
The ICD-10-CM code for gastritis is K29.70 — Gastritis, unspecified, without bleeding. This is the code the Alphabetic Index gives for gastritis with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
K29.70 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
