ICD-10 Code for Gangrene
Also indexed as (connective tissue) (dropsical) (dry) (moist) (skin) (ulcer)
The ICD-10-CM code for gangrene is I96 — Gangrene, not elsewhere classified. This is the code the Alphabetic Index gives for gangrene with no further qualifier, valid for FY2027 (October 1, 2026 – September 30, 2027).
I96 is billable but unspecified. If the documentation names a type, site or cause, one of the more specific codes below is likely expected.
Which gangrene code should you use?
The Alphabetic Index lists 32 codes under Gangrene, gangrenous. 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.
