I50.3 — Diastolic (congestive) heart failure
Is I50.3 billable?
No — I50.3 is a non-billable header code. I50.3 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 4 billable codes beneath I50.3.

Excludes1 — never code together
The conditions below can never be reported together with I50.3 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- combined systolic (congestive) and diastolic (congestive) heart failure (I50.4-)
Code also
Two codes may be needed to describe the condition fully. Whether I50.3 is sequenced first depends on the reason for the encounter.
- end stage heart failure, if applicable (I50.84)
Inclusion terms
Alternative wording in documentation that is classified to I50.3.
- Diastolic left ventricular heart failure
- Heart failure with normal ejection fraction
- Heart failure with preserved ejection fraction [HFpEF]
Code first — inherited from I50
The underlying condition below must be sequenced before I50.3. I50.3 describes a manifestation and cannot be the principal or first-listed diagnosis.
- 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)
Excludes2 — not included here — inherited from Chapter 9
The conditions below are not part of I50.3, but a patient may have both at the same time. When documentation supports it, I50.3 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
- systemic connective tissue disorders (M30-M36)
- transient cerebral ischemic attacks and related syndromes (G45.-)
Excludes2 — not included here — inherited from I50
The conditions below are not part of I50.3, but a patient may have both at the same time. When documentation supports it, I50.3 and the excluded code may both be reported.

How long has I50.3 existed?
I50.3 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
