ICD-10 Code I13.2: Hypertensive heart and chronic kidney disease with heart failure and with stage 5 chronic kidney disease, or end stage renal disease
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 elevated blood pressure or hypertensive disease. The most accurate code depends on whether the condition is primary, secondary, or linked with heart or kidney involvement.
When is it used?
- May be used when a clinician documents hypertensive heart and chronic kidney disease with heart failure and with stage 5 chronic kidney disease, or end stage renal disease 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
- Primary care, cardiology, nephrology, and pre-operative documentation where blood pressure disease is part of the active problem list.
- Chronic disease follow-up and risk-adjustment workflows where hypertension status affects longitudinal care planning.
Common management context
- Clinical follow-up often includes blood-pressure measurement, medication review, kidney-risk assessment, and cardiovascular risk management.
- Documentation becomes more specific when the chart links hypertension with heart failure, chronic kidney disease, or another secondary cause.
- Specialist context already linked on this page includes Cardiologist, General Physician, ENT Specialist, Urologist.
🔍Key distinctions
Important notes
- ICD-10 hypertension coding is often broader than the actual treatment plan; the exact code depends on whether associated heart or kidney disease is documented.
- Secondary hypertension and hypertensive heart or kidney disease generally require more specific codes than uncomplicated essential hypertension.
- When hypertension is documented with heart or kidney involvement, the linked disease context usually affects code specificity.
