Heart failure

In Other forms of heart disease (I30-I5A), chapter 9: Diseases of the Circulatory System

23 billable codes under I50: 6 are an MCC, 7 are a CC; all map to HCC 226 (Heart Failure, Except End-Stage and Acute), HCC 225 (Acute Heart Failure (Excludes Acute on Chronic)), HCC 224 (Acute on Chronic Heart Failure) and 1 more HCCs.A CC or MCC (major CC) is a secondary diagnosis that raises the MS-DRG payment. An HCC counts toward a Medicare Advantage patient's risk score.

About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Heart Failure

Heart failure means that your heart can't pump enough oxygen-rich blood to meet your body's needs. Heart failure doesn't mean that your heart has stopped or is about to stop beating. But without enough blood flow, your organs may not work well, which can cause serious problems.
