- heart failure due to hypertension (I11.0)
- heart failure due to hypertension with chronic kidney disease (I13.-)

Documentation support
General coding-documentation guidance — not a substitute for payer-specific requirements or professional coding judgment.
- •This is a non-billable header code. Documentation must support a more specific child code before this diagnosis can be reported on a claim.
- •Laterality-specific codes exist for this condition — confirm the affected side is documented.
- •This code represents a manifestation. Documentation should identify the underlying condition, which must be coded first.
- •As a general rule, code to the highest level of specificity supported by the documentation in the medical record.
