ICD-10 Code I23.2: Ventricular septal defect as current complication following acute myocardial infarction
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. This code sits within the broader ICD-10 area for Diseases of the circulatory system (I00-I99).
đź“‹Clinical overview
This ICD-10 code is commonly used when documentation describes a current complication following acute myocardial infarction. The most accurate code depends on whether the active complication is hemopericardium, septal defect, cardiac or valvular rupture, thrombosis, or another specified post-MI complication.
When is it used?
- May be used when a clinician documents ventricular septal defect as current complication following acute myocardial infarction in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code can be used as a clinically usable diagnosis entry in standardized coding workflows.
What it does not mean
- A code alone does not explain severity, treatment plan, or outcome.
- A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
đź©şClinical context
When commonly used
- Inpatient, cardiology, critical-care, and utilization-review workflows where an acute myocardial infarction is complicated by a current structural, thrombotic, or mechanical cardiac consequence.
- Coding workflows where the chart identifies the specific post-MI complication and that complication changes final code specificity beyond the acute myocardial infarction itself.
Common management context
- Evaluation often includes hemodynamic assessment, echocardiography or catheterization context, rhythm and thrombotic review, and coordination across cardiology, critical-care, and procedural teams.
- Documentation usually becomes more specific when the chart identifies the exact post-MI complication such as hemopericardium, septal defect, wall rupture, papillary or chordal rupture, thrombosis, or another specified current complication.
- Specialist context already linked on this page includes Cardiologist, General Physician.
🔍Key distinctions
Important notes
- This ICD-10 family captures current complications following acute myocardial infarction rather than the acute myocardial infarction itself.
- The exact current complication pattern drives the final code specificity inside this family.
- Ventricular septal defect as a current complication following acute myocardial infarction is coded separately from atrial septal defect, hemopericardium, rupture patterns, thrombosis, and other post-MI complication patterns.
- Documentation that describes a current complication following acute myocardial infarction is coded differently from the acute myocardial infarction itself, chronic ischemic heart disease, or remote prior myocardial infarction without active complication.
Important exclusions
- acquired ventricular septal defect not specified as current complication following acute myocardial infarction (I51.0)
