I25.119Atherosclerotic heart disease of native coronary artery with unspecified angina pectoris

Billable / specific codeICD-10-CM

I25.119 is a billable, specific ICD-10-CM code for atherosclerotic heart disease of native coronary artery with unspecified angina pectoris. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

  • unspecified angina pectoris without atherosclerotic heart disease (I20.9)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

  • Atherosclerotic heart disease with angina NOS
  • Atherosclerotic heart disease with ischemic chest pain

Excludes2 inherited from the categories above I25.119

Also inherited, and the opposite of Excludes1: these conditions are not part of I25.119, but a patient can have both, so you may code both.

Written on I25.1 Atherosclerotic heart disease of native coronary artery

  • atheroembolism (I75.-)
  • atherosclerosis of coronary artery bypass graft(s) and transplanted heart (I25.7-)

Written on I25 Chronic ischemic heart disease

  • non-ischemic myocardial injury (I5A)

Risk adjustment

I25.119 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.
