I50.4 — Combined systolic (congestive) and diastolic (congestive) heart failure
I50.4 is a non-billable header ICD-10-CM code for combined systolic (congestive) and diastolic (congestive) heart failure. It cannot be billed on its own: choose one of the more specific child codes below.
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.
- Combined systolic and diastolic left ventricular heart failure
- Heart failure with reduced ejection fraction and diastolic dysfunction
Other codes that can never be billed with I50.4
These codes carry an Excludes1 note pointing at I50.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I50.4 alone.
Risk adjustment
I50.4 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
