I50.3-I50.33Primary Range

Heart failure codes specific to diastolic dysfunction

This range includes codes for chronic diastolic heart failure, both stable and acute on chronic.

Hypertensive heart disease with heart failure

Used when hypertension is a contributing factor to heart failure.

Key Information: ICD-10 code for chronic diastolic congestive heart failure

Essential facts and insights about Chronic Diastolic Congestive Heart Failure

Chronic diastolic congestive heart failure is coded as I50.32 in ICD-10. Ensure documentation includes ejection fraction and symptoms.

Primary ICD-10-CM Code for chronic diastolic congestive heart failure

Chronic diastolic (congestive) heart failure
Billable Code

Decision Criteria

clinical Criteria

  • Ejection fraction ≥50% confirmed by echocardiogram

documentation Criteria

  • Documented symptoms of heart failure and preserved ejection fraction

Applicable To

  • Chronic diastolic heart failure
  • Heart failure with preserved ejection fraction (HFpEF)

Excludes

  • Systolic heart failure (I50.2-)
  • Combined systolic and diastolic heart failure (I50.4-)

Clinical Validation Requirements

  • Ejection fraction ≥50%
  • Echocardiogram showing diastolic dysfunction
  • Symptoms of heart failure such as dyspnea, orthopnea

Code-Specific Risks

  • Incorrectly coding as systolic heart failure
  • Lack of documentation for ejection fraction

Coding Notes

  • Ensure documentation specifies chronic diastolic heart failure with preserved ejection fraction.

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 as a primary code when hypertension is a contributing factor.

Chronic kidney disease, stage 3

N18.3
Use when CKD is present and contributes to heart failure.

Differential Codes

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

Acute on chronic diastolic (congestive) heart failure

I50.33
Use when there is acute decompensation in a patient with chronic diastolic heart failure.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Chronic Diastolic Congestive Heart Failure to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code I50.32.

Impact

Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential for reduced reimbursement.

Mitigation Strategy

Ensure echocardiogram results are included in the patient's record., Train staff on the importance of documenting ejection fraction.

Impact

Reimbursement: Incorrect coding can lead to lower DRG assignment., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data affecting patient care.

Mitigation Strategy

Always specify 'diastolic' or 'systolic' and document ejection fraction.

Impact

Risk of audits due to non-specific documentation of heart failure.

Mitigation Strategy

Implement training on detailed documentation practices.

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.

Outpatient follow-up for chronic diastolic CHF

Specialty: Cardiology

Required Elements

  • Type and acuity of heart failure
  • Ejection fraction
  • Symptoms and treatment plan

Example Documentation

Patient with chronic diastolic CHF, EF 55%, stable on diuretics.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has CHF.
Good Documentation Example
Patient has chronic diastolic CHF with EF 55%, stable on current regimen.
Explanation
The good example provides specificity and clinical details necessary for accurate coding.
