Complete code families applicable to Acute Diastolic Heart Failure

I50.3-I50.33Primary Range

Heart failure codes specific to diastolic dysfunction

This range includes codes for acute, chronic, and acute-on-chronic diastolic heart failure, which are essential for accurate documentation and coding of diastolic heart failure conditions.

Key Information: ICD-10 code for acute diastolic heart failure

Essential facts and insights about Acute Diastolic Heart Failure

The ICD-10 code for acute diastolic heart failure is I50.31, applicable when the condition is acute with preserved ejection fraction.

Primary ICD-10-CM Code for acute diastolic heart failure

Acute diastolic (congestive) heart failure
Billable Code

Decision Criteria

clinical Criteria

  • Documented EF ≥50% with acute symptoms

documentation Criteria

  • Acuity and causal relationship must be documented

Applicable To

  • Acute decompensated diastolic heart failure

Excludes

  • Chronic diastolic heart failure (I50.32)
  • Acute-on-chronic diastolic heart failure (I50.33)

Clinical Validation Requirements

  • Ejection fraction ≥50%
  • Echocardiogram showing diastolic dysfunction
  • Elevated BNP/NT-proBNP levels

Code-Specific Risks

  • Risk of using unspecified codes if acuity is not documented
  • Audit risk if EF is not documented

Coding Notes

  • Ensure documentation includes EF and specifies the acuity of heart failure.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Hypertensive heart disease with heart failure

I11.0
Use when hypertension is documented as the cause of heart failure.

History of tobacco use

Z87.891
Use if there is a documented history of tobacco use.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Unspecified diastolic heart failure

I50.30
Use I50.31 for acute cases with documented acuity and preserved EF.

Chronic diastolic heart failure

I50.32
Use I50.32 for chronic cases without acute exacerbation.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Acute Diastolic Heart Failure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.31.

Impact

Clinical: Leads to incomplete clinical assessment., Regulatory: Non-compliance with coding guidelines., Financial: Potential loss of reimbursement due to incorrect DRG assignment.

Mitigation Strategy

Use terms like 'due to' or 'secondary to' in documentation., Ensure all relevant conditions are linked in the clinical notes.

Impact

Reimbursement: May result in lower reimbursement due to unspecified coding., Compliance: Increases risk of audit and non-compliance., Data Quality: Leads to poor data quality and inaccurate clinical records.

Mitigation Strategy

Ensure documentation specifies 'acute' or 'acute-on-chronic' to use I50.31 or I50.33.

Impact

Missing documentation can lead to incorrect coding and audits.

Mitigation Strategy

Implement standardized templates for documenting heart failure.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Documentation Templates for Acute Diastolic Heart Failure

Use these documentation templates to ensure complete and accurate documentation for Acute Diastolic Heart Failure. These templates include all required elements for proper coding and billing.

Acute diastolic heart failure in a hypertensive patient

Specialty: Cardiology

Required Elements

  • Ejection fraction
  • Acuity of heart failure
  • Causal relationship with hypertension

Example Documentation

74F with acute diastolic HF (EF 58%, E/e' 16) secondary to hypertensive crisis (BP 190/110).

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has heart failure.
Good Documentation Example
Acute diastolic HF (EF 60%) with pulmonary edema, secondary to uncontrolled hypertension.
Explanation
The good example specifies the type, acuity, and cause of heart failure, which is necessary for accurate coding.
