ICD-10 code for gangrene
From the official ICD-10-CM alphabetic index entry “Gangrene, gangrenous (connective tissue) (dropsical) (dry) (moist) (skin) (ulcer)”. Page updated September 29, 2026.
About coding gangrene
The ICD-10-CM code for gangrene is I96 (Gangrene, not elsewhere classified). The official index lists 62 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I96.
Don't report I96 together with the conditions in its Excludes1 note: gangrene in atherosclerosis of native arteries of the extremities (I70.26), gangrene in hernia (K40.1, K40.4, K41.1, K41.4, K42.1, K43.1-, K44.1, K45.1, K46.1), gangrene in other peripheral vascular diseases (I73.-), gangrene of certain specified sites - see Alphabetical Index and 2 more.
The conditions in its Excludes2 note aren't part of I96, but may be coded alongside it if the patient has both: gangrene in diabetes mellitus (E08-E13 with .52).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.
