Range Overview

high priority

The ICD-10 code range I05-I09 is dedicated to chronic rheumatic heart diseases. These codes are used to document various forms of rheumatic heart disease, including rheumatic mitral valve diseases, rheumatic aortic valve diseases, and other rheumatic heart diseases. The codes in this range help to classify the severity and complications of the disease, which is essential for appropriate treatment and management.

Key Usage Points:

  • Always specify the type of valve disease (mitral, aortic, tricuspid, etc.)
  • Include the presence of any complications such as heart failure or atrial fibrillation
  • Specify the severity of the disease if known
  • Use additional codes to identify any associated conditions
  • Remember to code first any underlying streptococcal infection

Coding Guidelines

When to Use:

  • When a patient has a diagnosis of chronic rheumatic heart disease
  • When a patient has complications from chronic rheumatic heart disease
  • When a patient has a history of rheumatic fever and has developed heart disease
  • When a patient has multiple valve diseases resulting from rheumatic fever
  • When a patient has aortic or mitral valve disease without mention of rheumatic origin

When NOT to Use:

  • When a patient has acute rheumatic fever without heart involvement
  • When a patient has a non-rheumatic heart disease
  • When a patient has a heart disease not specified as rheumatic or non-rheumatic
  • When a patient has a heart disease resulting from conditions other than rheumatic fever

Code Exclusions

Always verify the rheumatic origin of the disease before using these codes.

Documentation Requirements

Documentation for chronic rheumatic heart diseases should clearly specify the type of disease, any complications, and the severity of the disease. The documentation should also include any associated conditions and whether the disease is a result of rheumatic fever.

Clinical Information:

  • Type of rheumatic heart disease
  • Presence of any complications
  • Severity of the disease
  • Associated conditions
  • History of rheumatic fever

Supporting Evidence:

  • Clinical notes
  • Laboratory results
  • Imaging reports
  • Referral letters
Good Documentation Example:

Patient with severe chronic rheumatic mitral valve disease with complications of heart failure. History of rheumatic fever in childhood.

Poor Documentation Example:

Heart disease

Common Documentation Errors:

  • Not specifying the type of valve disease
  • Not including complications
  • Not specifying the severity of the disease
  • Not mentioning the history of rheumatic fever

Coding Complexity

Medium
Complexity Rating

The complexity of these codes is medium due to the need to specify the type of disease, any complications, and the severity. There is also a need to identify any associated conditions and to code first any underlying streptococcal infection.

Key Factors:
  • Need to specify the type of valve disease
  • Need to include any complications
  • Need to specify the severity of the disease
  • Need to identify any associated conditions
  • Need to code first any underlying streptococcal infection

Specialty Focus

These codes are primarily used by cardiologists and rheumatologists. They can also be used by internists and family practitioners.

Primary Specialties:
Cardiology
60%
Rheumatology
30%
Clinical Scenarios:
  • A patient with a history of rheumatic fever presenting with heart murmur
  • A patient with severe rheumatic mitral valve disease and heart failure
  • A patient with rheumatic aortic valve disease and atrial fibrillation
  • A patient with multiple valve diseases due to rheumatic fever

Resources & References

Resources for these codes include the official ICD-10 coding guidelines, clinical references on rheumatic heart disease, and educational materials on ICD-10 coding.

Official Guidelines:

  • ICD-10-CM Official Guidelines for Coding and Reporting
  • World Health Organization ICD-10 guidelines

Clinical References:

  • American Heart Association guidelines on rheumatic heart disease
  • Journal articles on rheumatic heart disease

Educational Materials:

  • ICD-10 coding training materials
  • Online courses on ICD-10 coding

Frequently Asked Questions

Can I use these codes for a patient with aortic valve disease not specified as rheumatic?

No, these codes should only be used for diseases of rheumatic origin. For aortic valve disease not specified as rheumatic, use the appropriate code from the I35 range.
