R01.1

Cardiac murmur, unspecified

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 R01.1 is a billable code used to indicate a diagnosis of cardiac murmur, unspecified.

Key Diagnostic Point:

Cardiac murmurs are abnormal sounds produced by turbulent blood flow within the heart. They can be classified as either innocent (physiological) or pathological. Innocent murmurs are common in children and typically resolve without intervention, while pathological murmurs may indicate underlying heart conditions such as valvular heart disease, congenital heart defects, or heart failure. The murmur's characteristics, including timing, location, and intensity, are crucial for diagnosis. Murmurs can be detected during a physical examination using a stethoscope, and their presence may prompt further investigation through echocardiography or other imaging modalities. The unspecified designation indicates that the specific type or cause of the murmur has not been determined, necessitating further evaluation to ascertain its clinical significance.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of murmur characteristics
  • Need for additional diagnostic tests to determine etiology
  • Differentiation between innocent and pathological murmurs
  • Potential for co-existing cardiac conditions

Audit Risk Factors

  • Inadequate documentation of murmur characteristics
  • Failure to document follow-up evaluations or tests
  • Misclassification of innocent vs. pathological murmurs
  • Lack of correlation with clinical findings

Specialty Focus

Medical Specialties

Internal Medicine

Documentation Requirements

Detailed description of the murmur, including timing, location, and intensity, along with any associated symptoms.

Common Clinical Scenarios

Patients presenting with fatigue, palpitations, or chest pain where a murmur is detected during routine examination.

Billing Considerations

Consideration of patient history, including prior cardiac conditions and family history of heart disease.

Emergency Medicine

Documentation Requirements

Acute care documentation must include the context of the murmur, associated symptoms, and any immediate interventions.

Common Clinical Scenarios

Patients presenting with acute chest pain or dyspnea where a murmur is identified during the emergency evaluation.

Billing Considerations

Rapid assessment of the murmur's significance in the context of acute cardiac events.

Coding Guidelines

Inclusion Criteria

Use R01.1 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the murmur is documented clearly and that any associated conditions are coded appropriately

Exclusion Criteria

Do NOT use R01.1 When
No specific exclusions found.

Specialty Considerations

Cardiology may require more detailed echocardiographic assessments.

ICD-10 Improvements

The transition to ICD-10 has allowed for more specificity in coding cardiac murmurs, enabling better tracking of patient outcomes and resource utilization.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specificity in coding cardiac murmurs, enabling better tracking of patient outcomes and resource utilization.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the difference between an innocent and pathological murmur?

An innocent murmur is typically benign and occurs in healthy individuals, often resolving without treatment. A pathological murmur indicates an underlying heart condition that may require further evaluation and management.
