Heart failure (I50)

Browse all the diagnosis codes used for heart failure (i50). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range. This format makes it simple to browse diagnosis codes in this chapter or section and find what you're looking for. We've also added green checkmark icons to label billable codes, and red warning icons for non-billable ones. This makes it easy to identify which codes can be billed.

Clinical Information

Diastole - Post-systolic relaxation of the HEART, especially the HEART VENTRICLES.

Heart Failure - A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.

Heart Failure, Diastolic - Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.

Heart Failure, Systolic - Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.

Systole - Period of contraction of the HEART, especially of the HEART VENTRICLES.

Instructional Notations

Code First

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

• heart failure complicating abortion or ectopic or molar pregnancy O00 O07 O08.8
• heart failure due to hypertension I11.0
• heart failure due to hypertension with chronic kidney disease I13
• heart failure following surgery I97.13
• obstetric surgery and procedures O75.4
• rheumatic heart failure I09.81

Type 2 Excludes

A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

• cardiac arrest I46
• neonatal cardiac failure P29.0
