I50.22 - Chronic systolic (congestive) heart failure

Clinical Definition

Heart failure with preserved ejection fraction (HFpEF), also known as diastolic heart failure, is characterized by symptoms of heart failure despite a normal ejection fraction (typically ≥50%). The heart pumps normally but has trouble filling with blood due to stiff ventricles.

Documentation Requirements

• Specific type/classification of heart failure (preserved EF)

• Current ejection fraction percentage (must be ≥50%)

• Acuity (acute, chronic, acute on chronic)

• Severity (NYHA Class I-IV)

• Associated symptoms/signs

• Any underlying causes

• Treatment plan and management

Common Synonyms

• "Diastolic heart failure"

• "Stiff heart syndrome"

• "Heart failure with normal ejection fraction"

• "HFpEF" (abbreviation)

Coding Conflicts

Excludes1:

• Heart failure with reduced ejection fraction (HFrEF)

• Heart failure with mid-range ejection fraction (HFmrEF)

Scribing.io Automation

Our AI scribe automatically:

• Identifies EF percentages from echo reports

• Tags mentions of diastolic dysfunction

• Captures NYHA classification documentation

• Links documented symptoms to heart failure criteria

• Flags documentation gaps in required elements

• Suggests specificity when "heart failure" is mentioned without type

To ensure clean coding:

• Use "HFpEF" or "preserved EF heart failure" in assessment

• Document current EF percentage

• Include NYHA classification

• Link relevant symptoms to the diagnosis
