Frequently Asked Questions
What is the ICD-10 code for subsequent stemi & nstemi mocard infrc?
The ICD-10-CM code for subsequent stemi & nstemi mocard infrc is I22. The full clinical description is "Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction". I22 is a non-billable header code. Use a more specific child code for billing purposes.
What does ICD-10 code I22 mean?
ICD-10-CM code I22 represents “Subsequent ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction”. It is classified under Chapter 9: Diseases of the Circulatory System and is a non-billable header code. Use a more specific child code for billing purposes.
Is I22 a billable code?
No, I22 is a non-billable header code. You need to use one of its more specific child codes for billing. There are 5 child codes under I22.
What chapter is I22 in?
I22 is in Chapter 9: Diseases of the Circulatory System (codes I00-I99).
What codes cannot be used with I22?
I22 has Excludes1 notes indicating codes that cannot be used together with it, including: subsequent myocardial infarction, type 2 (I21.A1); subsequent myocardial infarction of other type (type 3) (type 4) (type 5) (I21.A9).
What are the subcategories under I22?
I22 has 5 child codes, including: I22.0 (Subsequent STEMI of anterior wall), I22.1 (Subsequent STEMI of inferior wall), I22.2 (Subsequent non-ST elevation (NSTEMI) myocardial infarction), I22.8 (Subsequent STEMI of sites), and 1 more.
Are additional codes required with I22?
Yes, when using I22, also report: code, if applicable, to identify:; exposure to environmental tobacco smoke (Z77.22); history of tobacco dependence (Z87.891); occupational exposure to environmental tobacco smoke (Z57.31); status post administration of tPA (rtPA) in a different facility within the last 24 hours prior to admission to current facility (Z92.82); tobacco dependence (F17.-); tobacco use (Z72.0).
What are the UMLS CUIs for I22?
I22 is linked to 12 UMLS Concept Unique Identifiers: C0027051, C0010072, C0151814, C0264686, C0264688, and 7 more. The UMLS (Unified Medical Language System) integrates multiple biomedical vocabularies maintained by the U.S. National Library of Medicine.
How does I22 relate to ICF functioning codes?
ICF (International Classification of Functioning, Disability and Health) codes describe how conditions like subsequent stemi & nstemi mocard infrc affect a person's functioning — body functions, activities, participation, and environmental factors. AutoICD provides ICF Core Sets for 12+ conditions and can map clinical text to ICF categories automatically. Browse the ICF directory to explore functioning codes.
What is the ICD-11 equivalent of I22?
I22 maps to the ICD-11 code: BA42.Z (Subsequent myocardial infarction, unspecified).
