What This Code Means

Narrowing of heart arteries causing chest pain with characteristics that don't fit the standard angina patterns.

Coding Tips

  • Use this code for atypical presentations such as angina equivalent symptoms or unstable angina patterns
  • Document the specific type of angina presentation to support medical necessity

Clinical Significance

This code captures atherosclerotic heart disease of native coronary arteries with angina presentations that do not fit the standard classifications of unstable, vasospastic, or refractory angina. This may include atypical angina equivalents such as exertional dyspnea, nocturnal angina, or other variant presentations. Proper capture ensures that the anginal component of the disease is coded alongside the underlying coronary artery disease.

Documentation Requirements

  • Documentation of coronary artery disease involving native vessels
  • Description of the specific angina presentation that does not fit unstable, vasospastic, or refractory categories
  • Clinical characteristics of the anginal episodes
  • Diagnostic evidence supporting ischemia
  • Treatment plan

Excludes 1 — Do NOT code together

  • other forms of angina pectoris without atherosclerotic heart disease (I20.8-)
