Excludes1 — never code together
The conditions below can never be reported together with I50.814 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- Right heart failure with but not due to left heart failure (I50.82)
Code also
Two codes may be needed to describe the condition fully. Whether I50.814 is sequenced first depends on the reason for the encounter.
- the type of left ventricular failure, if known (I50.2-I50.43)
Inclusion terms
Alternative wording in documentation that is classified to I50.814.
- Right ventricular failure secondary to left ventricular failure

- transient cerebral ischemic attacks and related syndromes (G45.-)
Excludes2 — not included here — inherited from I50
The conditions below are not part of I50.814, but a patient may have both at the same time. When documentation supports it, I50.814 and the excluded code may both be reported.
How long has I50.814 existed?
I50.814 first appears in FY2018 (FY2017 is not available, so it may have appeared then).
