Non-billable headerICD-10-CM

I50.3 is a non-billable header ICD-10-CM code for diastolic (congestive) heart failure. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • combined systolic (congestive) and diastolic (congestive) heart failure (I50.4-)

Code also

Both codes may be needed to describe the encounter fully. Sequencing depends on the reason for the visit.

  • end stage heart failure, if applicable (I50.84)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Excludes2 inherited from the categories above I50.3

Not part of this code, but both may be coded when both are present.
