Gangrene, not elsewhere classified (I96)
ICD-10 code I96 is used specifically for cases of gangrene not classified elsewhere. This code captures various forms of tissue death due to impaired blood supply that don’t fall under more specific gangrene categories.
This code covers a wide range of conditions including gangrene caused by peripheral vascular disease, skin necrosis from drug reactions like heparin-induced thrombocytopenia or coumarin therapy (known as coumarin necrosis), and necrosis of surgical flaps or stomas. It also includes rare types such as gangrene of fingers, toes, or feet, bilateral presentations, and pressure injuries that become gangrenous. Professionals looking for the ICD-10 code for ischemic gangrene or terms like peripheral gangrene, acral gangrene, or radionecrosis of the skin after radiation treatment will find I96 relevant. This code helps medical coders precisely document various non-specific gangrenous conditions when the exact cause or location is not detailed in other ICD-10 codes.
Instructional Notations
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
- Gangrenous cellulitis
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
- 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
- gas gangrene A48.0
- pyoderma gangrenosum L88
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Ergotism
Poisoning caused by ingesting ergotized grain or by the misdirected or excessive use of ergot as a medicine.
