Non-ischemic myocardial injury (non-traumatic) (I5A) ICD-10-CM
The I5A code range covers non-ischemic myocardial injury (non-traumatic) with 1 ICD-10-CM diagnosis codes. 1 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
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.
- Acute (non-ischemic) myocardial injury
- Chronic (non-ischemic) myocardial injury
- Unspecified (non-ischemic) myocardial injury
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
- the underlying cause, if known and applicable, such as:
- acute kidney failure N17
- acute myocarditis I40
- cardiomyopathy I42
- chronic kidney disease CKD N18
- heart failure I50
- hypertensive urgency I16.0
- nonrheumatic aortic valve disorders I35
- paroxysmal tachycardia I47
- pulmonary embolism I26
- pulmonary hypertension I27.0 I27.2
- sepsis A41
- takotsubo syndrome I51.81
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.
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.
