ICD-10 Code I50.82: Biventricular heart failure
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 heart failure or impaired cardiac pumping function. The most accurate code depends on whether the record identifies the heart-failure type, side, acuity, or ejection-fraction context.
When is it used?
- May be used when a clinician documents biventricular heart failure 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
- Emergency, inpatient, cardiology, and chronic-disease documentation where fluid overload, reduced cardiac function, or decompensation is part of the active problem list.
- Risk-adjustment, utilization-review, and follow-up workflows where heart-failure specificity affects longitudinal care planning and treatment review.
Common management context
- Heart-failure follow-up often includes symptom review, volume-status assessment, medication reconciliation, cardiac imaging context, and monitoring for worsening congestion or reduced function.
- Documentation usually becomes more specific when the chart identifies systolic or diastolic dysfunction, acute versus chronic status, left or right-sided failure, or reduced ejection fraction.
- Specialist context already linked on this page includes Cardiologist, General Physician, ENT Specialist.
🔍Key distinctions
Important notes
- ICD-10 heart-failure coding is often more specific when the record identifies acute, chronic, combined, systolic, diastolic, or side-specific heart failure detail.
- Heart failure may coexist with hypertension, valvular disease, kidney disease, arrhythmia, or ischemic disease, but related conditions may still require their own linked codes.
